Cordless stick vacuum cleaners are hoovering up market share from more traditional cylinder and upright vacuums. But is a cordless cleaner right for your home?
The slimline, portable design of cordless vacs makes them light and convenient for whipping round the house, but their small dust capacity and the limitations of the battery life means they aren't suitable for all homes.
Plus, we've found only a few can match the cleaning power of the best corded vacuum cleaners.
Cordless vacuum cleaners are lighter than most ordinary upright vacuum cleaners, weighing an average of 3kg compared with 7kg for a standard vacuum.
They're easy to move around too, as you aren't hampered by a cord or your proximity to a plug socket. If you're cleaning up high though, you will have to shoulder the whole weight of the vac as you clean.
Many come with wall mounts so instead of rifling through the cupboard under the stairs you can just grab and go. This makes them ideal for quick clean-up jobs - when you've spilled crumbs over the kitchen for example, or stomped bits of grass all over the hall carpet.
Some are designed just for floor cleaning, but most have accessories which make tackling smaller cleaning jobs such as cleaning your car, or the stairs, easier.
Many early cordless vacuums barely lasted 20 minutes, but runtime has improved on more premium models over the years.
If you need to use high-power mode - if you have lots of carpet for example - you'll find the battery life drops dramatically. The (£500) gives 60 minutes cleaning time on eco mode, but just 12 on turbo.
You might save time when cleaning with a cordless vacuum, but you'll likely spend more time emptying it and cleaning the filters. If you don't, your vacuum cleaner will get less effective at picking up dirt as it gets blocked up.
If you're an allergy sufferer, this isn't ideal either as it means more regular contact with the dust. There are some bagged cordless vacuums available though, which have larger capacities, such as the and .
Some bagless models have features designed to prevent dust escaping, such as Dyson's dirt ejector - a silicone collar which pushes debris into the bin.
The most important thing about a vacuum cleaner is how well it cleans, and this is where some cordless cleaners will really let you down.
The best models can leave carpets clean and keep dust safely locked up. But with more than one in three cordless vacs we test being so poor we name them Don't Buys, you'll need to choose carefully - especially if you have a carpet-heavy home.
These figures shows the best dust pick up from carpet results we have recorded for robot, cordless and corded vacuum cleaners.
Scores show the amount of dust picked up from thick carpet by the best vacuum cleaner we tested in each category.
Aside from cleaning power, you'll also want to be sure a cordless vacuum cleaner will last long enough for you to get the cleaning done.
Battery life varies wildly, from as little as seven minutes on full power for some models, to more than an hour on others. Generally, the more you pay, the more battery life you'll get.
It's worth considering whether you're happy cleaning little and often or if you want to be able to tackle the whole house in one go. If you have lots of carpet, check how long the battery lasts for on the higher power settings recommended for carpets.
How long a cordless vac takes to recharge can vary from an ultra-fast 60 minutes to more than sixteen hours.
Cheaper models may have longer recharge times, which could be frustrating if you are halfway through the cleaning when your battery dies.
Of course, a long battery life is worthless if it can't clean effectively. We test runtime and recharging time for each model, so to find out which cordless cleaners hit the sweet spot between battery life and effective cleaning head to our list of the .
Cordless vacuum cleaners are undeniably light and convenient, but only a few are truly effective at sucking up dust and dirt in your home.
