Cordless vacuum cleaners free you from the plug socket, making for easier and quicker cleaning.
They are often stick-shaped, light and manoeuvrable, and can be handy for awkward cleaning jobs such as vacuuming your car or stairs.
Originally considered an extra vacuum for quick clean-ups in between full-home cleans, the very best cordless vacs are now good enough at cleaning to replace your corded vacuum.
Beware, though: only a few models truly clean well. Our independent tests of popular models have uncovered plenty of dreadful vacuums that will fail to clean your home.
Watch our video guide to choosing a cordless vacuum, or read on for more advice on pricing, features and key brands.
There are three main types of cordless vacuum cleaner:
While most cordless vacuum cleaners are bagless, there are a few versions with disposable dustbags. These have the advantage of larger dust capacities, so you'll need to empty them less often. You'll need to factor in the ongoing cost of replacement dust bags, though.
Cordless vacuums range in price from around £50 to £600. Models from brands such as Bosch, Dyson, Samsung and Shark will usually set you back at least £180.
Our tests have shown that it's hard to find a great cheap cordless vacuum (although there are a couple out there), but spending a lot doesn't guarantee you a top-class vacuum cleaner. We've tested models costing more than £400 that are so poor at cleaning we've made them Don't Buys.
Most cordless vacuum cleaners have a handheld cleaning mode. This is usually either a pull-out handheld vacuum, or the more common stick design where you can swap the floor tool for mini tools.
You can also remove the cleaning tube entirely and attach the tools to the main vacuum unit to make a small handheld vacuum. This is great for cleaning in tight spaces, up high and in places that are difficult to reach, such as in a car.
Some cordless vacuums are designed largely for cleaning floors and may have no handheld mode, or a rather clunky one. So it's worth thinking about what you need to clean before you buy.
You can also buy standalone handheld vacuum cleaners. These are usually cheaper and might be all you need if you just want something for tackling stairs and cleaning the car. See our for our top picks.
The amount of time you can use a cordless vacuum cleaner for depends on the type of battery it has and what setting you use it on. Lithium-ion batteries are generally the best for quicker charging and longer battery life.
Key things to check include:
When we test cordless vacuums, we assess battery life on both the highest and lowest settings and publish the results in our reviews, so you know whether or not they live up to the manufacturer's claims. We've found models that overstate battery life by as much as a third, which could mean you get caught short when cleaning.
Nearly all cordless vacuum cleaners have a small dust capacity, so you'll need to empty them more frequently. The average dust capacity is 0.6 litres compared with 2.1 litres for a corded model.
Most are bagless too, which means that you might have more contact with dust and debris while emptying than you would like. If you prefer a bagged vacuum, there are a couple of options. These also have have larger capacities. Check our reviews of the and to get our verdict on whether they are a good buy.
Cordless vacuum cleaners are much lighter than standard vacuums. On average, a cordless vacuum weighs 3kg compared with 6.4kg for a corded machine. Their light weight makes cordless vacuums a fantastic choice if you struggle with heaving a conventional corded cleaner around your home.
As well as weight, balance is key for a cordless vacuum cleaner. We've tested cordless vacuums that have a low overall weight but are poorly balanced. This can make the vacuum feel heavier in the hand, particularly when tackling jobs such as cleaning up high.
Our tests reveal that only a small handful of cordless vacuum cleaners are as good as the best traditional vacs at the tough tasks of cleaning fine dust from carpets and hard floors, and sucking up hair and fluff from around the home.
The best cordless vacuum cleaners will keep your floors dust and fluff-free, and be convenient, light and easy to use.
If you have a larger home, or one with lots of carpet, you may be better off with a corded vacuum. But if you're sick of lugging a corded model around, going cordless could make cleaning much easier – as long as you choose wisely.
Dyson is one of the most popular cordless brands. It has a wide range of models to pick from in four core ranges: V7, V8, V10 and V11.
As you go up the ranges, you get improved battery life, more features and increased capacity. Within each range you'll find various options, from 'Animal' to 'Absolute' or 'Total Clean' models.
As a general rule, they usually stack up something like this:
Prices can vary wildly, particularly on the older V7 and V8 ranges, which can make it difficult to know if you're getting a good deal. Head over to our guide on to unpick the differences between each of the cordless ranges and narrow down your search.
Don't disregard other brands, either. We've found rival cordless vacuums that are better at some cleaning tasks, have longer cleaning times or are cheaper. See our to compare all the popular models and find the best.
Shark has aspirations to be the new Dyson, and has launched a series of premium cordless vacuums over the last few years.
Its two main cordless ranges are:
Shark's DuoClean floor tool is similar to Dyson's 'fluffy' hard floor tool. It has a soft roller brush that rotates in the opposite direction to the main bristled turbo brush. This is meant to help pick up both larger debris on hard floors and fine dust on carpets.
Both models have a pet and non-pet version; the main difference is whether you get a mini turbo cleaning tool or not. Regardless of whether you have pets, this can be handy for cleaning the stairs. It's worth checking prices when you buy, as sometimes the pet version is the same price as the standard one, or even cheaper.
