Power cords got you wound up? We’ve spent more than 100 hours over the past few years looking into 80 different cordless vacuums, and after testing more than a dozen of them, we’re sure the Dyson V6 is the best choice. No cordless vacuum from any other brand matches the cleaning performance of the V6; in our tests, it picked up more ground-in dust and hair from our carpets than any competitor, and it cleaned up bare floors in fewer passes.

Last Updated: Eight months ago
We considered 7 new vacuums, including variants of some of our top pick from Dyson, but aren’t changing our picks. We’ve added those new models to the competition section below. Also, the Anker HomeVac Duo is now known as the Eufy HomeVac Duo. It’s the same product from the same company, just with a different brand label, and it’s still one our budget picks.
Expand Most Recent Updates
Nine months ago: We saw some new vacuums this year at CES including the Samsung Power S6050 and a new model from Eufy. Most interestingly, LG showed us its new H7 model, which could be a contender against our current top picks if it becomes available in the US. We've added all our thoughts down below.
10 months ago: Our picks have changed. The Dyson V6 is our pick for the best cordless vacuum, the Dyson V8 Absolute is our upgrade pick, and the Hoover Linx and the Anker HomeVac Duo are our two budget options.
11 months ago: We are finishing the update to this guide now. In the meantime, we’re putting it on Wait status because we no longer recommend the Hoover Air Cordless 2-in-1 (you can do better for the money these days). Our new main pick—good enough to replace a plug-in vac in apartments and some smaller homes—is the Dyson V6 base model. Our new budget pick for tidying up is the Hoover Linx. We also like the Anker HomeVac Duo 2-in-1 as a budget option, if you also want a hand vac. Our new upgrade pick for big houses is the Dyson V8 Absolute.
11 months ago: We’re working on an update for this guide right now, as we think expectations for a great cordless stick vacuum have changed since our last round of testing. If you’re looking to purchase one of our picks right now, please consider our upgrade pick—the Dyson V6. For our most up-to-date thoughts on all the types of vacuums we’ve tested, and help picking the one that’s best for you, check out our piece Which Vacuum Should I Get?
One year ago: We’ve added some long-term testing notes, owner reports of battery problems with our main pick, and a preview of the upcoming Dyson V8.
Two years ago: As battery-powered vacuums continue their development, we’ve added a few models to our What to Look Forward To section. The newly unveiled LG CordZero, which follows you around as you work like an enthusiastic puppy, is perhaps the most interesting concept of the bunch. Simplicity Vacuum has also released a new Cordless Vacuum, that mimics its corded cousin, the Simplicity Freedom, in both looks and power.
Two years ago: We’ve added long-term test notes for our main pick, updated our Competition section with some new dismissals, and added links to our new guide that can help you decide which kind of vacuum you should buy.
Two years ago: After 55 hours of research and testing, we’ve chosen the Hoover Air Cordless 2-in-1 BH52120 as our new main pick. If the BH52120 is unavailable, we recommend the Hoover Platinum Collection Linx Cordless, a capable machine that lacks handheld capabilities. If you’re looking to invest in a powerful cordless vacuum with a longer battery life than our top pick, the $300 Dyson V6, our upgrade pick, is for you.
Two years ago: We're changing our top pick to the Hoover Air Cordless 2-in-1 ($150). It's the handiest, most practical vacuum for most people who live in an apartment or small house with short carpets and bare floors. It cleans floors as effectively as any cordless stick vac at this price. What really sets it apart, though, is that it converts into a handheld vacuum (complete with two attachable tools), so you’ll be able to clean pretty much any surface in your home and your car, including crevices and upholstery. It's a phenomenal value. It's also worth noting that the Air Cordless 2-in-1 is a much different vacuum from the $200 Hoover Air Cordless that we dismissed in the previous version of this guide. That vacuum doesn't convert into a handheld vac, and underperforms compared to cordless vacs that cost less. Our old pick, the Hoover Linx, only cleans your floor. It's still a solid vacuum, but the Air Cordless 2-in-1 is much more versatile, and only costs $20 extra. If you want something that's better at cleaning short and medium carpets, with a longer battery life, our new step-up pick is the Dyson V6 base model ($300). Look for our updated guide with our latest research and testing in the next few weeks.
Three years ago: Updated with a couple new Dysons--the v6 ($300), the v6 Motorhead ($400), the v6 Animal ($500), the v6 Absolute ($600)--and the Hoover Air Cordless 2-in-1 ($150). You can read more here about why we don't recommend a Dyson right now. However, that could change eventually. Dyson tells us that once the v6 lineup goes on sale in March 2015, they’ll start offering refurbished batches of the DC59. They didn’t confirm the price, but we think that they’ll be about $230—the same as the refurbed DC44 goes for now. We’ll see how the situation shakes out, but the DC59 might be on the verge of becoming an excellent deal.  
Our pick
Dyson V6
No cordless vac from any other brand matches the cleaning power of the Dyson V6. Easy to steer, it works on carpets or bare floors and runs long enough to clean most small homes.

The V6 has about 17 minutes of constant run time, which is enough to clean most condos, apartments, or townhouses. Lightweight and easy to steer, it works well on carpets or bare floors and can convert into a handheld vacuum for cleaning shelves, windowsills, upholstery, or your car. This model is expensive, and it has only a two-year warranty, but that’s what it costs to get a cordless vacuum that’s good enough to replace a plug-in model—and based on the positive feedback from owners, lots of people think the V6 is worth the price. This Dyson used to be our upgrade pick, but now we’re making it our main pick (over the Hoover Air Cordless 2-in-1) because its performance goes far beyond the competition and the price is lower now than it was in previous versions of this guide. If you have the right kind of home for a cordless vacuum, the V6 is the best one for the money.

We think the base-model V6 is a great choice for most, and that’s the model we refer to throughout this guide. But Dyson also sells a few variants with tools that suit different needs, now at prices that are often competitive with or sometimes cheaper than the plain ol’ V6. If you have lots of carpet or want more handheld tools, give them a close look.

Budget pick

*At the time of publishing, the price was $120.

Hoover Linx
For quick pickups or good-enough apartment cleaning, the Hoover Linx is the sturdiest cordless vac for the money.

If you just need something affordable and convenient for tidying up a small space, the Hoover Linx (BH50010) is a tried-and-true option. It’s one of the most effective cleaners among budget-priced cordless vacs, and it has a respectable 16-minute run time. The foam filter is reusable, clogs and tangles are easy to clear, and the machine won’t need much general maintenance. Like its competitors at this price, it’s effective only at cleaning bare floors and maybe sweeping up some surface-level crumbs and hair from short rugs. The Linx has been available since 2009 and has thousands of customer reviews, so we know that most people should expect good performance over a couple of years. (This model used to be known as the Hoover Platinum Collection Linx; to the best of our knowledge, the new vacuum is exactly the same.)

Also great

*At the time of publishing, the price was $120.

Eufy HomeVac Duo
The Eufy has more battery life than our other budget pick, plus a pop-out hand vacuum, but it usually costs a bit more and lacks the Hoover’s strong reputation.

Another affordable cordless vacuum we really like is the Eufy HomeVac Duo (formerly known as the Anker HomeVac Duo; it’s the same product from the same company and Eufy is just their new homewares label). It has two advantages over its competitors: a 24-minute battery life, which is a few minutes longer than that of most other budget models, and a pop-out hand vacuum, so you can use it for more than just cleaning floors. Like the Linx, the Eufy HomeVac Duo is a competent bare-floor cleaner and okay at tidying up short rugs, and it won’t need much maintenance. The downside is that it’s a newer model from a brand that’s new to vacuums, so we don’t know if it has any reliability or quality-control problems yet.

Upgrade pick
Dyson V8 Absolute
With the power of Dyson’s V6 and twice the battery life, this model is the only good choice if you need to clean a big house in one session.

If your home is too big for the V6 to clean in one pass but you still want a cordless vacuum that cleans like a great plug-in, your only good choice is the Dyson V8 Absolute. It’s a lot like the V6 if it had twice the battery life—we timed it at 32 minutes per charge on the standard power setting—plus some extra accessories and a few other design tweaks. The average size of a new house in the US is about 2,400 square feet, and the V8 should almost be able to handle that floor space in a single session. The main drawback is that the V8 costs a lot of money but still has a relatively short expected lifespan. For a large home, a plug-in vacuum is a much more practical, cost-effective choice. But if you really want to use a cordless vacuum in a big house, get the V8.

Why you should trust us

In 2014, I counted 19 vacuums in my condo, and I might have forgotten a couple.

I’ve covered vacuums for The Sweethome for more than three years, logging hundreds of hours of vacuum research and testing in that time. I’ve personally tested dozens of vacuums of all types (cordless, robots, handhelds, and traditional plug-ins) in several homes with varied floor plans. And I have at least passing knowledge of hundreds more vacuums.

Other trivia: When I wrote this in 2014, I counted 19 vacuums in my condo, and I might have forgotten a couple. I’ve learned to preemptively explain the vacuum situation to guests when they come to my place for the first time. I’ve mostly lived in spaces where cordless vacuums are easier to use than plug-ins (including where I’m living right now), so I have a particularly good perspective on this guide.

In 2016, I put in an additional 19 hours of research and testing into about 27 new vacuums, plus dozens of additional hours of using our favorite vacuums to clean my own home.

Although we do our own testing, we also think it’s important to hear what other people have to say. We’ve interviewed a bunch of vacuum experts over the years, including:

I’ve also made a point to listen to as many of our readers as I can through comments on our guides, emails, Twitter exchanges, and message-board posts.

And I also like to read other vacuum reviews, including customer reviews (I’ve easily read more than 1,000) as well as reviews by other editorial sources like CNET, Consumer Reports, Good Housekeeping, and Reviewed.com.

Who should get this

The best cordless vacuums now have enough cleaning power to match good plug-in vacuums and enough battery life to clean small to midsize homes (roughly 1,200 square feet) in a single session. Obviously, the best part about owning a cordless vacuum is that you have no cable to unwrap and rewrap during every cleaning session or catch on corners and doorways. If you’ve ever skipped out on vacuuming because you’re feeling too lazy to unwrap the cord (guilty as charged) or your cramped floor plan makes cord-wrangling feel like a major chore, a cordless vacuum can be a life-changer.

But cordless vacuums have some disadvantages:

  • Cordless vacuums always cost much more than plug-ins with comparable cleaning performance and can’t consistently match the cleaning performance of the very best plug-ins on thicker carpets.
  • Cordless vacuums have shorter warranty periods than good plug-ins and shorter expected lifespans. That’s partly because the batteries in cordless vacs are likely to wear out after a few years.
  • Cordless vacuums have limited run times, and most can’t clean a big home in one session. For example, our favorite cordless Dyson lasts about 17 minutes, which is enough juice to clean about 1,200 square feet if you move pretty fast. But as of 2010, the Census Bureau reports (PDF) that the average new American home is about 2,400 square feet. Cordless vacuums also need at least three hours to recharge, so once the battery dies, you’ll need to walk away from cleaning for a while, even if you haven’t cleaned your whole home. (However, you could clean different parts of your home on different days, or just as needed, to avoid the battery life problem altogether.)
  • No cordless vacuum will keep your indoor air as clean as a great bagged plug-in, which is usually a dealbreaker for people with asthma or allergies.

This update covers new vacuums released since mid-2015, the last time we did a big update of this guide. We’re realigning a few things. Our old upgrade pick is now our main pick, and one of our old main picks is now a budget pick. We made these changes because attitudes toward cordless vacuums have shifted. Lots of our readers told us that they wanted a cordless vacuum to completely replace a plug-in vacuum, not just as a good-enough cleaner for small jobs. And as much as we tried to get the point across that our old main pick was best for tidying up apartments, some readers still bought it expecting it to work like a good plug-in and weren’t happy with the results. So we’re adjusting for those expectations.

If you need more help choosing the right vacuum for your home, we have a quick guide for that!

How we picked

cordless vacuum group testing

The cordless vacuums we tested for this guide (left to right): Hoover Cruise, Hoover Air Cordless Lift, Dyson V8 Absolute, Anker HomeVac Duo (now known as the Eufy HomeVac Duo), Dyson V6, Hoover Linx, Hoover Air Cordless 2-in-1, Black+Decker Smartech HSVJ520JMB. (Not pictured: Eufy HomeVac Lightweight.)

We started by making a list of all the cordless vacuums we could find. Since 2014, when we started covering this category, we’ve tracked 80 models (though many are now discontinued).

We looked for a cordless vacuum that cleans as well as a good plug-in.

For our main pick, we looked for a cordless vacuum that cleans as well as a good plug-in. That means it should suck up noticeable debris from bare floors and short- or medium-pile carpets in a couple of passes, as well as some of the less-noticeable fine dust and hair that accumulates deeper in carpets over time.

We narrowed in on models that met the following criteria:

  • An 18-volt battery or greater: More voltage does not necessarily mean more cleaning power, but 18 V is a good baseline for decent suction. Weaker batteries struggle with larger debris, like the road salt or chunks of food we sometimes cleaned up while testing.
  • A lithium or lithium-ion battery: Most cordless vacuums now use this battery type, but some old stragglers out there still use NiCD or NiMH batteries. Those types take much longer to recharge than lithium-based cells, and NiCD-based models are particularly awful because they start to lose suction about halfway through their running time.
  • At least 15 minutes of running time: That’s about the cutoff for 1,000 square feet of cleaning. Since we were looking for a cordless vacuum that could replace a plug-in, we wanted to find something that could work in more types of homes than just small apartments, even if it couldn’t quite handle the average American house.
  • Strong customer ratings: We’ve found that an average customer rating of four out of five stars is an accurate cutoff for user satisfaction. Any lower is a sign of a design flaw or quality-control problem.
  • A two-in-one design or a hose with attachments: Most of the time you’ll be cleaning your floors, but it’s handy to be able to transform your vacuum into a handheld so that you can clean windowsills, shelves, curtains, ceilings, upholstery, and tight spaces around furniture and appliances.

Other important features like reusable filters and swiveling joints are pretty much a given on any cordless vacuum these days. Warranties are also all fairly similar (two years), though we did favor brands with better reputations for responsive customer service.

After winnowing down the possibilities based on specs, we decided to call in four vacuums for testing that range in price from $180 to $300:

If you spend less than $180 on a cordless, it’ll lack a bunch of features and won’t come close to replacing a good plug-in vacuum. However, some cheaper picks work fine to tidy up smaller spaces—not a bad choice for a cozy apartment with no carpet, or as a secondary vacuum for your kitchen, for example. So we called in a few budget-friendly models for testing as well:

Every cordless vacuum that costs more than $300 is an upgraded version of the Dyson V6 (except for one model by Simplicity, which we’re not too excited about). These step-up models come with specialized cleaning heads that can eke out better performance in some scenarios. But the most compelling reason to spend more is to get extra battery life, and the only model that scratches that itch is the Dyson V8 Absolute (and a couple of variants on the V8). We called in the Absolute for testing, too.

How we tested

We test at home, using an evolving procedure to measure cleaning performance, handling, and ease of maintenance. These tests include cleaning trials using cat litter, baby powder, cat hair, steel-cut oatmeal, and lentils sucked up from wood floors, laminate floors, tile floors, low-pile area rugs, low-pile knit carpets, and medium-pile rugs. We test open-floor pickup, as well as side suction from corners and baseboards. And we try to measure the strength of a vacuum’s airflow by seeing how much debris it can clean up without actually driving over it.

Most cordless vacuums have about as much battery life as their manufacturers say they do, we’ve found. But we double-check anyway, because sometimes the vacuums meet their advertised run time only under certain conditions, like with the brush roller turned off, or with certain tools attached. We also listen for whether the suction drops off as the battery drains, though this problem is uncommon now that the industry has largely switched to lithium batteries.

For handling, we run each model through a timed slalom course to get a feel for steering and maneuverability. We drive through a few rooms, around and under a bunch of furniture, and over a mix of bare floors and rugs. The point is to see what it’s like to use each vacuum in a real-life apartment with a tight floor layout. Racing a vacuum through an obstacle course isn’t exactly how you would use one of these, naturally, but it clues us in on a few frustrations and flaws that might annoy owners, like how vacuums can bunch up area rugs or struggle to get around corners. In addition, we use each vacuum (when possible) for “above-floor” cleaning—upholstery, countertops, windowsills and curtains, stairs, and even the ceiling—to get a feel for handling and performance.

Our favorite tests are the stress tests. They give us the best idea of how each vacuum stands up to the dumbest operator errors (we’ve all made them). Basically, we try to clog and tangle each machine with tough debris like shredded copy paper, balls of cat hair, sawdust, and socks. And if we succeed in jamming them up, we figure out how to unclog them. The fewer tools and the less time needed, the better.

Our pick

cordless vacuum dyson v6 base model

The Dyson V6 base model has a cleaning head that works well on both carpets and bare floors.

Our pick
Dyson V6
No cordless vac from any other brand matches the cleaning power of the Dyson V6. Easy to steer, it works on carpets or bare floors and runs long enough to clean most small homes.

The Dyson V6 base model is the best cordless vacuum for most people because it cleans as well as a good plug-in vacuum on most common types of flooring and costs less than other Dyson cordless models. In our tests no other brand’s cordless vacuums came anywhere close to matching the carpet-cleaning performance of the V6. The V6 is also great on bare floors, and it can convert into a handheld vacuum, too. It’s lightweight and very thin, and most people find it easy to handle and to stash away between uses. With a 17-minute battery life (about average for the category), it’s best suited for an apartment or a smaller townhouse, where it can usually clean the whole space on a single charge—our estimate is about 1,200 square feet.

Cordless vacuums aren’t a great value compared with plug-in vacuums because they rarely last as long, have limited run times, and can’t handle long carpet well. But if do you have the right kind of home for a cordless vacuum, the V6 is the best one for the money by a mile.

Dyson makes a handful of V6 variants that some people might want to consider depending on their flooring, but after looking at all the configurations, we think the base model is a good choice for most people because it works well on almost any surface and usually costs less than the others. Prices shift pretty rapidly these days.

cordless vacuum dyson v6 weight

The Dyson V6 weighs less than five pounds, making it one of the lightest vacuums available.

Cleaning performance is the most important feature here. It puts the V6 in a class above all other cordless vacuums. Nothing else we’ve tested (except for the flagship Dyson V8) comes close even on the standard power setting, let alone the boosted-power Max setting.

In our crumb-cleanup tests, the V6 usually picked up the majority of debris from a plush rug in one back-and-forth pass, which no other cordless vac managed. In powder-cleanup tests, it was the only model that consistently picked up most fine debris from floors on one pass (including from between floorboards) and from our short test rug in a couple of passes (or one pass on the Max setting). Other models left behind some dusty debris regardless of how many passes we made with them.

Other outlets rate the V6 highly, too. Consumer Reports (subscription required) gave Recommended status to all the variants of the V6 that it tested. CNET awarded four out of five stars to the Dyson V6 base model, tying the top rating that site has given to any cordless vacuum.

The most illuminating cleaning data we got wasn’t even from a controlled cleaning test. I was in the process of moving out of an apartment, and I used the opportunity to get some hands-on time with a few vacuums. I used the Dyson V6 side by side with the Black+Decker Smartech HSVJ520JMB, one in each hand, to get a feel for how each one handled and how the battery life compared. The amount of dust and hair that the V6 pulled out of the carpeting, on just one battery charge and on the regular power setting, put the Smartech HSVJ520JMB to shame. Check this photo out:

cordless vacuum dyson v6 black+decker smartech comparison

The Dyson V6 managed to pick up much more ground-in debris (left) than the Black+Decker Smartech HSVJ520JMB (right) when we used them side by side over a single charge.

The V6 can clean more effectively than other cordless vacuums mostly because it has a better motor. The so-called V6 digital motor spins at 110,000 rpm; as the company claims, it “spins three times faster” than motors in other cordless vacuums (though Dyson reps did not share with us which model was used as a comparison). The faster rotation helps it create more suction, which helps it clean better. We don’t have details on how fast other cordless-vac motors spin, and Dyson’s marketing often makes claims that are technically true but presented out of context.1 But the proof is in the cleaning power here—we know from testing that the V6 is much stronger than other cordless vacuums. The motor is also much smaller and lighter than most other vac motors, which helps make the V6 one of the lightest overall vacuums.

The V6 also has a better brush roll than its competitors. The base-model cleaning head has four rows of edge-to-edge bristles, more coverage than on any other brush roll we’ve seen in cordless vacuums from other brands. That design helps it agitate carpet more thoroughly, loosening up more debris from between fibers. It’s useful on bare floors, too, because it helps sweep up clingy debris that suction alone would not grab.

Dyson’s customer service gets fewer bad reviews than other brands’ departments. Nobody has good data to show that certain brands have faster or more responsive customer service than others, but we do know that very few customer reviewers for the V6 at Amazon even mention Dyson’s service. That bodes well for reliability. And those owners that do mention customer service, even if they leave a bad review for the product, tend to mention that customer service is at least “friendly and helpful,” as reviewer Bridget Gustafson does. We’ve found the same thing in our own interactions. Wirecutter staff writer Nick Guy called looking for a solution to poor suction, and the representative walked him through the steps to clear a clog, which fixed the problem. We can’t find many recent stories about Dyson going above and beyond to help customers, but we also can’t find examples of people feeling like they got totally screwed or dismissed by the service team when a serious hardware problem cropped up. We’d love to hear your stories, good or bad.

The V6 is easy to steer and pleasant to handle, all things considered. At about five pounds, it’s a shade lighter than our other contenders and one of the lightest vacuums available anywhere. The swivel joint at the cleaning head turns as tight as anything we’ve seen on any vacuum. Since the V6 is so narrow and nimble, it can get into tight spaces much more easily than other vacuums—between or under furniture, for example, or reaching for the ceiling. It has some downsides that we cover in the Flaws but not dealbreakers section, but on balance, the design is an asset.

The V6 can convert into a handheld vacuum and take attachments like the combo brush (pictured).

Like most cordless vacuums, the V6 doesn’t take up much floor space and can easily fit into a closet between uses. It doesn’t even need to take up any floor or closet space at all: You can screw the charging dock into a wall, and the V6 can just hang there without touching the ground.

Customer ratings for the V6 are excellent for a vacuum. Other variants of the V6, such as the Motorhead and Absolute models, have great ratings as well (slightly better than the base model, actually), also based on many hundreds of reviews each.

cordless-vacuum-dyson-v6-cannister-empty-630

The V6 has a trap door for emptying the dust bin, but you’ll still have to get your hands dirty some of the time.

No amount of additional run time can offset the V6’s advantage on cleaning power.

We’d estimate that the V6 has enough battery life to clean somewhere between 1,000 and 1,200 square feet on a single charge, depending on how fast you work, how much open space you have, and how much carpeting you’re trying to clean. To think of it another way, we clocked it at about 17 minutes, running constantly, on the standard power setting (or about 6 minutes on the boosted-power Max setting) with the cleaning head attached. Your actual cleaning sessions might last a little longer than that. With the head detached, it can run for 20 minutes because it’s not using any extra power to drive the brush roll, so you’ll earn back a little time if you switch to handheld mode for a bit. And the trigger-style power switch turns the vacuum off when you loosen your grip, so you’ll save juice whenever you pause.

The 15-to-20-minute range is a typical run time for a cordless vacuum these days, and the V6 actually has the shortest run time among all our main-pick finalists. However, no amount of additional run time can offset the V6’s advantage on cleaning power, so the modest run time is a limitation we think most people who live in apartments and condos can learn to live with.

The V6 is also easier to unclog and untangle than most cordless vacs, because it comes apart in so many places. The cleaning head pops off, the brush roll slides out, a plate comes off the bottom of the head, and the extension tube detaches from the dust bin. So while it clogs and tangles about as easily as other cordless vacuums, we’ve found that it’s easier to fix.

The cleaning head on the V6 base model comes apart in a few places, so it’s relatively easy to unclog and untangle.

Like other cordless vacuums, the V6 comes with a reusable filter and a belt that should last the lifetime of the machine. You probably will not need to pay for any replacement parts while you own the V6.

Flaws but not dealbreakers

The Dyson V6 costs way more than a comparable plug-in vacuum. For some owners, it does not live up to the expectations they had for the price. We can’t blame them, and we want to make sure you know what you’re getting into before you decide to buy this or any other cordless vacuum instead of a handheld.

The most common complaint we read about the V6 is that it doesn’t have enough battery life. The average newly built American home is about 2,400 square feet, according to the 2010 Census Bureau (PDF), but we’ve found that the V6 can clean about 1,200 square feet on one charge if you work quick. The battery needs about four hours to recharge completely, which is typical for vacuums with this run time.2 It’s also built permanently into the body of the vacuum, so you can’t swap it out for a fresh battery. And the V6 won’t run while charging, either—you can’t use it like a plug-in vacuum—so once the battery is empty, you’re done cleaning for the better part of the day.

If your home is too big for the V6 to cover in one pass, your options are:

  • Get a plug-in vacuum. This is by far the most cost-effective option.
  • Get used to cleaning different sections of your home on different days, or at least at different times of the day, to give the battery a chance to recharge.
  • Upgrade to the Dyson V8, which doubles the battery life for an extra $200 (or more), or the Dyson V7, which adds 50 percent more battery life for an extra $100.

A couple of cordless vacuums have significantly longer run times than the V6 for roughly the same price, including the Hoover Air Cordless Lift and the Bissell AirRam. But in all of our testing, neither one was nearly as strong a cleaner as the V6.

We also came across several complaints that the V6 runs for less than 10 minutes, or that it can clean only a single room. That’s true on the Max power setting, but you can turn that off to extend the cleaning time out to 17 minutes. Just press the Max button on the back of the main assembly, so that the blue LED isn’t illuminated. If you’re still struggling with short run times even with Max mode turned off, get in touch with customer service.

Other V6 owners expected more cleaning power for the price. That’s understandable, but this is simply the strongest cordless vacuum apart from the Dyson V8. We’ve found that on its standard power setting, it cleans about as well as a good $150 plug-in vacuum like the Shark Navigator Lift-Away that we recommend in our guide to plug-ins. In Consumer Reports tests (subscription required), which used the boosted-power Max mode, the V6 actually outperformed many plug-in models.

The V6 base model comes with only a single tool, a combo brush. No turbo tool for quickly cleaning upholstery, not even a simple crevice tool. For $300, that’s a raw deal. However, at the time of writing, Dyson.com is giving away three extra tools of your choosing with the purchase of the V6. That should be the standard offer.

Unrelated to the price expectations, we found a few other common complaints:

The V6 doesn’t work on high-pile carpets or rugs, because the fibers wrap around the brush roll, and you have no way to turn off the brush roll. You should not expect the V6 to work on shag, saxony, cable-cut, or other types of rugs or carpets with long, loose fibers. Some people find that the V6 base model is even hard to push across mid-pile plush carpets, though we didn’t find that to be a problem. If your floors are mostly carpet, you could upgrade to one of the V6 variants with the direct-drive carpet-cleaner head (like the V6 Motorhead), which works great on mid-pile carpets.

Small, lightweight area rugs often get tangled up in the V6, because the suction is strong and the brush roll is very aggressive. Bigger and heavier rugs, rugs held down by furniture, or rugs with rubber backing should stay in place.

The base model of the V6 acts like a snowplow—that is, the cleaning head sometimes pushes around large pieces of debris (think cereal) without sucking them up. If you have a toddler who likes to toss Cheerios off the high chair, you can use the V6 without the cleaning head attached (just the open extension tube) to pick up the pieces instead. Alternately, buy one of the V6 variants with the soft-fiber cleaning head, like the V6 Total Clean.

Since the cleaning head doesn’t have a locking joint, the V6 can’t stand up under its own power. You’ll either need to wall-mount the dock (which involves drilling holes) or get used to leaning the vacuum up against a wall or shelf.

Some people find that the trap door to the dust bin opens too easily. We’re not sure if it’s just “too easily” for some people’s preferences or if certain units have a faulty seal at the trap door. In our testing, we have not had this issue.

Noise is an issue for some people. In short: The volume is fine for short periods, but the high pitch can be annoying. We measured the V6 at about 80 dBC on the standard power setting, which can fatigue your ears over time, though usually not within the vacuum’s 20-minute maximum battery life. It’s also completely typical for a cordless vacuum, right in the middle with others we’ve tested. However, it does have frequency spikes at 4,000 Hz and 7,000 Hz, which come across as a high-pitched whine that can be irritating. And on Max mode, it’s louder and whinier, running at 84 dBC, spiking at an even-higher-pitched 6,500 Hz and 10,500 Hz. Most cordless vacuums are not pleasant to listen to, and the V6 is no better than the lot, but we think most people can deal with it.

Driving the V6 can be hard on your wrists. It’s a top-heavy vacuum, so you’re holding the bulk of the weight in your hands. You also need to squeeze the power trigger constantly while you’re vacuuming. As loose as the action on the trigger is, pressing it is still an effort. Personally, the V6 has at times aggravated my lingering case of tendonitis, though I’ve learned to relax my death grip on the trigger. People with arthritis pain may find the V6 too uncomfortable to use.

The V6 can cut out unexpectedly during use, though the problem is uncommon. While this symptom can mean the battery or the wiring is faulty, it usually means the intake is clogged, or the filter is very dirty, or the brush roll is jammed or tangled. When the V6 senses an obstruction like a clog or tangle, it turns itself off to protect the motor from burning out or the belt from popping. So before you panic about the power source, run through your care-and-maintenance checklist to see if you can find a simpler cause. Another possible cause is that the trap door to the dust bin is not fully sealed. Try wiping off the gasket and reclosing it.

We’ve heard reports of chronic clogging in the V6, though we really don’t know if it’s more or less common than with other cordless vacuums. Parts of the intake path are fairly narrow—particularly right at the entrance to the dust bin—so big tufts of thick pet hair may cause blockages. Wirecutter staff writer (and owner of several pets) Nick Guy tested the V6 for about a year and had to deal with occasional pet-hair clogs. Again, run through the basic steps for care and maintenance to see if that fixes the problem. But if you have pets with long hair, you may be better off buying a great plug-in model like the Shark Navigator Lift-Away, which has wider intakes, a longer warranty period, and a lower upfront cost to offset the risks of chronic problems.

Even if debris doesn’t cause performance problems, it can get caught in hard-to-clean parts of the V6. The upper part of the dust bin is the most obvious spot—hair gets wedged between the walls of the dust din and the cyclone, and most people’s fingers are too thick to pull it out. You’ll need a pipe cleaner or some other stick-like tool to unwedge the debris. The bearings on the tiny wheels at the front of the cleaning head are another pain point for hair and fuzz buildup; we know from experience that over time those bearings can get so jammed up that the wheels won’t roll anymore. You’ll need to spend some time with a pair of tweezers or needle-nose pliers getting the debris out. Try to stay ahead of the problem with regular cleanings.

And again, the Dyson V6 is an expensive vacuum. As good as the test results and most of the owner reviews are, nobody can guarantee that this thing will work well for you. And the cost makes it a somewhat riskier buy than a plug-in vacuum. If you have any doubts about this vacuum, that it’s more trouble than it’s worth or that it can’t handle your flooring and layout, you should probably pass. But if the upsides of a cordless vacuum feel like they’re worth that risk, the Dyson V6 is the best choice for most people.

Long-term test notes

I’ve personally been using a version of the V6 off and on for close to three years.

I first tested it when it was known as the DC59, released back in early 2014. I knew right away it was a great vacuum for an apartment, but at $500, it was too expensive to recommend to many people. Now that the price has dropped, the V6 is a better value.

I’ve also been able to see how these vacuums hold up over time: We’ve had the same V6 floating around between Sweethome staff members since mid-2015, and a DC59 has been making the rounds since early 2014. We haven’t had to do anything out of the ordinary to keep the test units running well—just washing filters, cutting away tangles, and clearing clogs.

A tried-and-true choice for modest messes

cordless vacuum hoover linx

Budget pick

*At the time of publishing, the price was $120.

Hoover Linx
For quick pickups or good-enough apartment cleaning, the Hoover Linx is the sturdiest cordless vac for the money.

A cheaper cordless vacuum can work for small jobs like picking up crumbs off the kitchen floor, or as a “good enough” cleaner for a home with mostly bare floors. If that’s what you’re after, we think the Hoover Linx (BH50010) is the best choice. For the price, it’s as durable and effective as a cordless vac can get.

The Linx is a competent floor cleaner, a little more capable than others at its price. It can pick up visible debris from bare floors and surface debris from short rugs and carpets. The side brushes pull particles away from baseboards pretty reliably. The Linx is not strong enough to suck up much of the fine dust in your carpets—nothing at this price is. But if you’re mostly cleaning bare floors and area rugs (which you can pick up and shake out by hand from time to time), the Linx is a fine way to keep your floors tidy. If you’ve only ever used a cheap vacuum anyhow, the Linx will seem normal.

Compared with other inexpensive cordless vacuums, the Linx is sturdy. If you use it a few times per week for tidying up, it should last for two or three years before an important part breaks without needing much maintenance. We can’t guarantee that longevity, but it is an educated guess: The Linx has been around since 2009 (which is amazing for this category because it changes so rapidly) and has thousands of customer reviews that we can reference, so we feel like we’re drawing from a solid data set about its build quality.

The Linx is not strong enough to suck up much of the fine dust in your carpets—nothing at this price is.

Maintaining the Linx is easy enough. As with many other vacuums, you’ll need to rinse (and air-dry) the foam filter every few weeks. You’ll also need to untangle hair from the brush roll and baffle tube from time to time, which is as easy as cutting it away with scissors or a razor blade. The bearings on our test unit stayed free and clear of hair after a few years of use, so you shouldn’t have to worry about cleaning those. It’s also easy to unclog, because the intake tube between the cleaning head and the entrance to the dust bin is only a few inches long, short enough to fish out obstructions with a finger or a pipe cleaner. You probably won’t have to change the belt and may not need to buy any replacement filters. We don’t anticipate any ongoing costs of ownership within the expected two- or three-year lifespan, though replacement parts are widely available if you need them.

The Linx comes with one battery that lasts for about 16 minutes with the brush roll running, by our measure. That’s enough time to tidy up most condos or apartments and typical for cordless vacuums at this price (which range from 11 minutes up to about 24 minutes at full power). The battery is removable and charges in a separate dock, so if you want, you can buy a second battery and swap between them as needed.

Handling is reasonably smooth and light on the Linx. While the joint at the cleaning head is stiffer than on some competing models, it still swivels a bit and is pretty easy to turn and get under some furniture. The angled handle also makes this model easier to steer and recline than the straight stick-style handles on other cordless vacs.

The Linx gets high ratings on Amazon from over 8,000 reviews. That is an enormous number of ratings over many years, so we’re confident that most people are happy with what they paid for.

cordless vacuum hoover linx

While the Hoover Linx doesn’t swivel as fully as other models, the reclining handle makes it easier to slip the Linx under chairs and tables without straining your wrist.

The main downside to the Linx is that it does not have a hose or removable hand-vac component, so you can’t use it to clean your car, windowsills, or anything besides flooring. That was a common limitation a few years ago, but now most cordless vacuums have some sort of above-floor cleaning capability. If you’re looking for an affordable two-in-one cordless vac, we have a recommendation below.

This is a decent tidy-up cleaner, but it’s not in the same league as our main pick.

The Linx is not really meant to be repaired, nor is it built to withstand heavy use. Judging from customer reviews we’ve read, our estimate is that if you’re using the Linx for more than three battery cycles per week, the plastic construction may not hold up as long as you’d hope. If you try to pry open the body, it may not go back together. The Linx has a two-year warranty, but it explicitly covers only defects, not wear and tear. Plus, we’ve read dozens of owner reviews that say Hoover’s customer service can be difficult to deal with; many of those reviews complain of long wait times and several layers of escalation before anything gets resolved.

We also want to reiterate that this is a decent tidy-up cleaner, but it’s not in the same league as our main pick in this guide and definitely not on a par with a good plug-in vacuum. In previous versions of this guide, we may not have done as good a job as we should in getting that point across. Don’t expect this model to fully clean plush carpets or reliably pick up after three dogs—those are tough jobs meant for vacuums better than this.

And as solid as the Linx has been, nobody can guarantee against bad production runs in the future.

Hoover released the Linx Signature (BH50020). At the time of writing, it costs the same as the regular Linx (BH50010). We’ve confirmed with Hoover that these are exactly the same vacuum—they are “different in terms of looks only,” a rep told us. So grab whichever version costs less, or whichever one you prefer to look at.

A budget model with a longer battery life

cordless vacuum anker eufy homevac duo

Also great

*At the time of publishing, the price was $120.

Eufy HomeVac Duo
The Eufy has more battery life than our other budget pick, plus a pop-out hand vacuum, but it usually costs a bit more and lacks the Hoover’s strong reputation.

If you want a budget cordless vacuum with more battery life or the ability to pull double duty as a hand vacuum, check out the Eufy HomeVac Duo (formerly known as the Anker HomeVac Duo). Like the Hoover Linx, the Eufy HomeVac Duo can’t compete with the Dyson V6 in cleaning power, but it’s useful for tidying up.

Eufy is not a familiar name in vacuums. It’s the homewares sub-label of Anker, a popular maker of battery and charging accessories, including a handful that we recommend. So the jump to battery-powered vacuums isn’t a huge stretch.

The HomeVac Duo’s biggest advantage over the Linx is its extra running time. We clocked it at about 25 minutes at full power, so nine minutes more than the Linx (and eight minutes more than the Dyson V6). That’s better for larger spaces, but it also gives you some flexibility if you tend not to recharge the vacuum after every small job. The HomeVac Duo can also run for up to 60 minutes on “eco” mode, but we found the suction to be so weak that it’s essentially useless for anything but dust bunnies.

The other upside is that the HomeVac Duo can convert into a handheld vacuum for tidying up windowsills, countertops, crevices, and anything else that’s not the floor. It comes with two attachable tools: a combo brush tool and a crevice tool. It’s not a particularly strong handheld vacuum, but it can come in handy for easy jobs.

cordless vacuum anker eufy homevac duo

The Eufy HomeVac Duo has a pop-out handheld vacuum.

The Amazon customer ratings for the old version, the HomeVac Duo, are very strong, as are the ratings for the updated model.

The HomeVac Duo can also fold at the handle into roughly half its normal height. We haven’t seen that feature in any other vacuum before, and we aren’t sure how useful it’ll be. It could be convenient for people who live in very small homes and want to be able to store this vacuum in a small cubby or under a bed. It’s also easy to repack into its box, which is not something we can say for most other vacuums.

In other ways, the HomeVac Duo is pretty typical for a cordless vac. Cleaning performance is good on bare floors and for getting surface-level grit and hair out of short carpets. In our tests, it picked up most obvious, midsize debris in one or two passes, which is pretty quick for this type of vacuum. At least in the first couple of weeks of testing, the suction was a little stronger than we expected, though we don’t know how it will hold up over time. Handling is light and nimble. Taking it apart to clean clogs and tangles is easy. Not much maintenance is required apart from keeping the filter clean.

The big unknown with the HomeVac Duo is that we don’t have much historical brand data about Eufy vacuums. This is the company’s first model, and we don’t know if they’re built to last. To be fair, we don’t always know that about brand-name vacuums either until they’ve been out for a few years. But we’ve found that two-in-one style vacs like this get grimy and lose suction faster than nonconvertible vacuums do. The crevices in the dust cup are tricky to clear out completely, we’ve found, so debris builds up over time, to the detriment of the air flow.

Unmatched power and a big boost in run time

cordless vacuum dyson v8 absolute

Upgrade pick
Dyson V8 Absolute
With the power of Dyson’s V6 and twice the battery life, this model is the only good choice if you need to clean a big house in one session.

If you want a cordless vacuum that can suck up as much debris as a plug-in vacuum and clean an entire house on a single charge, the Dyson V8 Absolute is as good as you can get.

The V8 is a lot like the V6, if it had about twice as much battery life. We timed it at slightly more than 32 minutes per charge on the standard power setting. That puts it right on the edge of being able to clean 2,400 square feet, the average size of a new house in the US. The boosted-power Max mode, which can pull fine dust out of a carpet like a very good plug-in vacuum, ran for 8 minutes by our measure (it’s worth noting that’s only a couple of minutes longer than the V6 on Max mode, not twice as long).

As a newer model, the V8 has a few other refinements over the V6. The dump-lever pops the cyclones away from the dust bin like a Transformer, so it’s easier to fully empty the vacuum without getting your hands dirty. While both vacuums use the same motor, extra sound insulation makes the V8 run about 8 dBC quieter than the V6, with less of a high-pitched whine—it’s easier on the ears than any other effective cordless vacuum we’ve tested so far. And while we didn’t notice a big difference in our at-home testing, upgrades to the electronics allegedly give the V8 stronger suction, which may help it pull more dust from carpets.

cordless vacuum dyson v8 absolute accessories

All the accessories that come with the Dyson V8 Absolute, clockwise from the top: extension tube, charger, soft-roller cleaning head for bare floors, direct-drive cleaning head for carpets, combo tool, mini turbo tool, crevice tool, the V8 itself, charging dock.

That’s all great, but the issue here is price. The everyday street price for the V8 Absolute is about $600, which is a ton of money for a vacuum with a two-year warranty and an expected lifespan of less than five years. We’ve seen it for $480 on sale, but that’s still wicked expensive. Even the cheaper variants on the V8 are very expensive. The steep price makes this model hard to recommend wholeheartedly, when plug-in models with better filtration, unlimited run times, and decades-long lifespans cost the same.

Plug-in models with better filtration, unlimited run times, and decades-long lifespans cost the same amount of money.

But if you understand the caveats and still think the V8 is right for you, go for it. We’ve had a great time testing it, and it’s a wonderful vacuum.

The V8 Absolute comes with two cleaning heads (the direct-drive carpet head and the soft-roller bare-floor head), plus a bunch of attachments, including a mini motorized tool. Other V8 variants come with fewer tools or less battery life. It’ll work on most types of flooring, including mid-pile carpets that the V6 base model might struggle with. Long, loose carpets still pose a problem.

The competition

The Hoover Air Cordless 2-in-1 used to be our top pick in this guide. But we got lots of feedback from readers who expected that since it was our top recommendation, the Air Cordless 2-in-1 would be a much stronger cleaner than it really was, even though we tried to emphasize that its abilities were limited. So we shifted the focus of the guide to vacuums that can legitimately replace a plug-in vac in most apartments and small homes. As for the Air Cordless 2-in-1, it’s not even one of our favorite budget models anymore—time has passed it by. The 11-minute battery life is significantly shorter than that of newer competing models like the EufyAnker HomeVac Duo. And we’ve come across many documented cases of battery defects, which makes it tough to keep recommending when a trooper like the Hoover Linx is available. The Air Cordless 2-in-1 is still a decent little vacuum, but we now think you have better options.

The Air Cordless 2-in-1 is still a decent little vacuum, but we now think you have better options.

Dyson makes several variants of the V6—all the same vacuum, just different accessories. We’ve recommended the base model throughout this guide because it’s relatively affordable and the cleaning head works well on both carpets and bare floors, so it can work for pretty much anyone. But depending on your flooring, you might want to consider another variant. Here are the important details:

The most common one is the V6 Motorhead, which comes with a direct-drive cleaning head designed for getting more dust and hair out of carpets. It’s not so great on bare floors, though, because the aggressive brush action can scatter midsize debris across the room instead of scooping it into the vacuum. It also comes with a combo tool and crevice tool.

The V6 Total Clean variant comes with every accessory you’ll reasonably need. It has the same accessories as the V6 Motorhead, plus a dusting tool, a mini turbo tool for easily cleaning hair off of upholstery (super-handy for pet owners), and a soft-roller cleaning head designed for getting all types of debris off of bare floors, including large particles like cereal. In our experience, the basic cleaning head on the base-model V6 already works great on any kind of flooring, so the two-heads setup feels a little superfluous—but they do improve the cleaning ability.

Less-common variants include the V6 Animal, V6 Absolute, V6 Slim, V6 HEPA, and V6 Fluffy, all of which have some combination of the tools and cleaning heads already mentioned. Some of them have a HEPA filter, which is useless—the standard filter is already excellent, and emptying the V6 will always kick dust back into the air, undoing all the extra filtration anyway.

The street prices for these Dyson variants shift constantly, and as of early 2017, they were competitive with the base model’s price. We can’t give you some magic number where one variant becomes better than another for the money, because everyone values each tool and cleaning head a little differently. The base model is a safe bet for most cordless-vac shoppers, but if you see a great deal on a different version and think you’d gain something from attachments, go for it. Also remember that you can always buy the attachments separately if you need them.

Dyson also sells two V8 variants. Compared to the V8 Absolute, the V8 Animal leaves out the soft-roller head, which is inconvenient if you have bare floor, and the HEPA filter, which is no great loss. It costs $100 less, which makes it a pretty good deal if you can live without the bare-floor cleaner. The V7 Motorhead is in the same chassis as the V8, but its battery life is halfway between the V6 and V8—we’re guessing it’ll get about 25 minutes of run-time, based on Dyson’s claim of 30 minutes. It’s a decent in-betweener option if you want more battery life, though it does not come with a mini turbo brush, which is a letdown for the price.

The Eufy HomeVac Lightweight is a stronger vacuum with a longer battery life than the Hoover Linx, for a similar price, with a similar design. We considered making it one of our budget picks, and we may do so in the future. If you find it for a lower price than the Linx and like the way it looks, go for it. However, this Eufy is a new vacuum from a brand that’s new to the category, whereas the Linx has a long, positive track record, so we’re sticking with it for the time being.

The Hoover Air Cordless Lift comes with two 25-minute batteries, more than enough run time to vacuum a big house. (We actually clocked each battery at an impressive 28 minutes per charge in our tests.) That’s much more battery life than the Dyson V6 (or even the V8) offers, for a much lower price. It also has a five-year warranty, the longest coverage we’ve seen for a cordless vacuum. But the Air Cordless Lift was not that strong of a cleaner in our tests, as we found that it left behind dusty debris in carpets. It did not perform well in Consumer Reports tests, either, and it’s heavier than any other cordless vacuum we tested. If you like the extended run time and the general design of the Air Cordless Lift, you’d probably be better off getting a similar plug-in vacuum, like the Shark Navigator Lift-Away that we recommend.

The Hoover Cruise looks like it was designed to mimic the Dyson V6 as closely as possible without technically infringing on any patents. It even has a trigger-style power button. But the Cruise is not in the same league as the V6. In our tests, the suction was much weaker and the brush roll had less bristle coverage, so the Cruise was not nearly as effective a cleaner on any surface. It does have one neat feature we’d like to see Dyson adopt: a lock for the trigger switch, so that you don’t need to keep squeezing it throughout the cleaning session.

The Black+Decker Smartech HSVJ520JMB has the right specs to compete with the Dyson V6 and even adds some neat features like a floor-type sensor, which automatically adjusts the suction when you switch from bare floors to rugs and vice versa. But the HSVJ520JMB’s cleaning power was pitiful in our tests—it just did not clean carpets effectively at all, barely able to pull surface-level hair out from the fibers. From what we have read about other Black+Decker cordless vacuums, we suspect they’re not any better.

The Bissell AirRam wasn’t really one of our top contenders—it’s a floors-only cleaner, with no hose or convertible hand-vac component—but Bissell sent us one to test anyway. It has a long battery life, which we clocked at about 36 minutes. Consumer Reports gave it Excellent marks for carpet and bare-floor cleaning, right up there with all the Dyson models. That seems like a great recipe for an affordable whole-house cleaner. But it just did not perform well in our cleaning tests on floor or carpets, particularly with dusty debris. As tempting as the specs and some test results might look for the price, we think this model would fall short of most people’s expectations for cleaning power.

Tons of other cheap cordless vacuums are available from the likes of Bissell, Black+Decker, Electrolux, Hoover, and others. We have not tested all of them, but based on our research we believe that our budget picks in this guide are better choices than any of those.

Apart from the Dyson V8, the only other really high-end cordless vacuum is the Simplicity Cordless Freedom. According to Simplicity, it has a 44-volt battery and more than an hour of run time, which is very impressive. But it’s even pricier than the Dyson V8, and it can clean only floors—no hose, no convertible hand vacuum. We tested a plug-in version of this vacuum a while back, and it was nothing special when it came to carpet cleaning, either. The Cordless Freedom represents a nice attempt by an old-school brand to embrace the future, but we would not recommend it over the Dyson V8.

What to look forward to

We saw a few interesting vacuum models at the CES 2017 trade show. The LG H7 appears to be a convincing Dyson V6 knockoff. The specs placard said the motor can move up to 140 air watts, up from 100 air watts in the Dyson. That number tells only part of the story, but the H7 seems to be a lot stronger than any other cordless stick vac we’ve seen. So far, Dyson is way ahead of the competition in this category, but it would be refreshing to have a serious challenger. We’ll see if this one stands up, but LG showed off vacuums at the last two or three CES shows that never made it to the US. LG representatives did not have any information on pricing or a target release date.

Samsung also showed us a new two-in-one model, the Power S6050. It’s more like an Electrolux or Eufy vacuum than a Dyson. However, Samsung does not have much of a reputation for good vacuums, at least not in the US.

 

Care and maintenance

We’ll have a more thorough article on care and maintenance covering a wider variety of vacuums coming soon. But in a nutshell: Keep your filters clean according to manufacturer directions. Empty the bag or dust bin when it’s full. Check for clogs and tangles if the vacuum is having trouble cleaning. Follow the manufacturer’s directions for maintaining the health of the battery.

Oh, and seriously—if your pet pees on the carpet, never try to clean it with a vacuum.

Footnotes:

1. A couple of examples of context-free advertising: Dyson once claimed that one of its cordless vacuums had “zero carbon emissions,” a phrase suggesting that the vacuum makes no contribution to the carbon-dioxide pollution driving climate change. However, it’s a true statement only in the sense that the motor has no carbon-fiber brushes, so it can’t emit carbon dust. Dyson reps told us that the “zero carbon emissions” statement “was always meant to refer to the motor having no carbon-fiber brushes, and therefore not emitting carbon dust. However, to your point, we started getting feedback that it caused the exact type of confusion you’re pointing out, so we stopped using this phrasing.”

Dyson had also long claimed that its bagless vacuums had “no loss of suction.” But when the company released the first Dyson Cinetic model in 2014, it then claimed that this model was “the only vacuum that won’t lose suction.” If that claim was true about the new model, what did that mean about the decade of advertising that came before? We asked Dyson for comment, and reps explained that the old claim was based on an industry-standard test for maintaining suction as the bin fills just once. The new claim means that the Dyson Cinetic is designed not to lose suction over 10 years of use, based on a modification of the industry-standard test that “follows its main protocol, but just extends it out to account for use over a period of time. The test we use is the same test as the original no loss of suction test that we repeat for 10 years’ worth of use.” Jump back.

2. The V6 has about the same battery capacity as an iPhone 7 (2 Ah), so why does it take so much longer to recharge? That’s because the V6 runs at a higher voltage (21 V versus 3.8 V), and such a fast discharge is harsh on a battery. Dyson balances that and preserves longevity with a recharge cycle that’s gentler (meaning slower). A phone is the opposite: With a gentler discharge cycle, it can recharge faster.
