Best cordless vacuum cleaners for 2021

From the best cheap cordless vacuum to which Dyson is best, we recommend the top models to buy in 2021

Cordless vacuum cleaners tend to be lighter and easier to use than corded vacuums, making cleaning feel like less of a chore. But not all cordless models are an improvement on a standard vac – we've found plenty that struggle to do the essential job of removing dust and dirt from your home. 

To help you avoid a dud, we've hand-picked our favourites from our full list of the best cordless vacuum cleaners, including our top cheap cordless model, the best option if you're keen on Dyson and the one to buy for dealing with pet hair. Each has gone through our rigorous lab tests, so you can be sure that it will be brilliant at cleaning your floors.

We've also found three models that are so dreadful, we think you should avoid them at all costs.

Best cordless vacuum overall

  • 85%
    £599.00

    This is the best cordless vacuum we've tested. It's brilliant at cleaning, has a lengthy battery life, and is really easy to use. What's more, it has nifty extras like a digital display that tells you how much cleaning time you have left, automatic suction control so you don't need to worry about changing settings when you switch surfaces, and a little accessory clip so you can take mini tools with you as you clean. It isn't cheap, but it's the one to go for if you want the best of the best.

Best cordless vacuum for larger homes

  • 83%
    £699.00

    This extra-large vacuum is packed with futuristic features, as well as a two-litre dust container and a 32-cm wide floorhead – perfect for covering extra floor space. It cleans well on all surfaces and picks up pet hair and larger debris with ease, but be warned: it's hard work to manoeuvre around a furnished home.

Best cheap cordless vacuum

  • 80%
    £229.99

    This model is one of the best cordless vacuums we've tested regardless of cost, making it even more of a steal. It's a real dust-buster on all surfaces and has no problem tackling larger debris or pet hair, too. There are cheaper cordless vacuums on the market, but you'll struggle to find a vac that’s better value for money.

Best cordless vacuum for pet owners

  • 83%
    £495.00

    If your home is always covered in pesky pet hair, this is the vac for you. It removes fluff and fur with ease, and does just as good a job at removing dust and larger debris from your home. And if you buy a compatible attachment, it can also be used as a steam mop – perfect for tackling muddy pawprints.

Best bagged cordless vacuum

  • 77%
    £250.00

    This is the only bagged cordless model that cleans to Best Buy standards. It's easy to use, and cleans very well on both carpets and hard floors. It comes with plenty of dust bags, and you can get a full service – which includes a new battery, new filters and software updates – for less than some other brands charge for a spare battery alone.

Three cordless vacuum cleaners to avoid

There's a lot to like about cordless vacuums, but it doesn't include this trio of poor performers. All three fail to achieve the most basic cleaning standards you'd expect from a vacuum – no matter how good their prices may seem, they're best avoided.

Only logged-in Which? members can view the vacuums to avoid in the table below. If you're not yet a member, join Which? to get instant access.

    £99.00

    This is one of the lowest-scoring vacuum cleaners we've ever tested. It totally fails to clean carpets and floorboards, and it’s also terrible at removing pet hair and retaining fine dust, making it a particularly bad choice if you suffer from allergies.

    It may look the part, but this cordless vacuum is terrible. In fact, it fails to suck up more than 90% of dust from floorboards, making it one of the worst vacuums we've ever tested.

    Despite being pitched to animal lovers, this pet model struggles to suck up fluff and fur. It's even worse at dealing with dust, removing less than a third of particles from carpets – and less than a quarter from floorboards.

Spending more or opting for a well-known brand won't guarantee you avoid a substandard vac. See our full list of Don't Buy cordless vacuums for the models to steer clear of.

Would a corded stick vacuum suit you better?

Corded stick vacuums have some of the benefits of cordless vacs. They have the same lightweight design and can often be used in a detachable handheld mode – but without the limited battery life.

They also tend be cheaper than cordless models. And because they don't have batteries, they can be lighter too.

Shark is one of the few big brands continuing to make this style of vacuum, so if you like the sound of it, take a look at our Shark vacuum cleaner reviews to see how they measure up on cleaning power.
