Which cordless vacuum should you choose? Find out in our shoppable video review

Thinking of swapping your corded vacuum for a cordless model? It can be tough knowing which brand and model to go for. Do you spent £199 or £400? What are you actually getting for your money?

Well, we put three of the best cordless vacuums from market leaders, Shark, Vax and Dyson to the test to show the differences. We compared not just their suction, but the battery life and any other features you get to make cleaning easier. Watch the video above to see them in action – it is shoppable so if you like what you see, just click the product to buy – then read on for more advice.

The contenders

• Dyson V11 Absolute – a lightweight, high-tech cordless vacuum with digital display and suction that automatically adjusts to the surface (above left). RRP £499.99.
• Vax Blade 2 Max –  a great-value, lightweight cordless vacuum that promises no loss of suction (above middle). RRP £199.
• Shark DuoClean with Flexology & TruePet – the only cordless vacuum that folds in half for easy storage without needing wall mounting. This model also flexes to clean under furniture and has anti-allergen seal (above right). RRP £479.99.

The results

We wanted to know how the vacuums perform on hard floors and carpets; how easy they are to empty; how long their batteries actually last; and how much they weigh. Here's how they compare:

1. Performance on different floors

All of the vacuums come with different heads for different surfaces but, let's be honest, who really bothers switching? We sprinkled breadcrumbs and crushed cornflakes on hard floor and carpet and set the vacuums loose using the standard heads. The Shark DuoClean is the heaviest of the bunch and that's partly due to its huge head, which had really impressive suction on both surfaces, but does make it a little tricker to manoeuvre.  The Vax Blade 2 Max is the easiest to move around but has the least sophisticated brush system, which we found didn't pick up as many bits on hard floors as it did on carpets. The Dyson V11 Absolute has the smartest tech here, automatically adjusting its suction as you move from hard floors to carpets when it's on Auto mode.

Winner = We love how the Dyson V11 Absolute automatically adjusts its suction levels depending on the surface

3. How long does the battery actually last?

If you're replacing your corded vacuum, then you want to know you can clean the whole house without having to stop and recharge. Here's how they performed in our test:

Joint winners = The Dyson V11 Absolute and Vax Blade 2 Max both exceeded their stated run times

2. Ease of emptying

There's nothing more frustrating then vacuuming the whole house then emptying the vacuum and spreading dust everywhere!  We found all three models easy to empty, once you'd got used to how they work. With the Shark DuoClean and Dyson V11, the handle and collection bin are attached to one another, so you have to remove the whole top half of the vacuum before you can empty them. This means they're harder to direct into the rubbish. The Vax Blade 2 Max is the only model where you can remove just the collection bin, which makes it the easiest to empty.

The winner = Being able to remove just the bin on the Vax Blade 2 Max makes it the easiest to empty

4. Weight and size

Two of the most important features of any cordless vacuum is that it is lightweight and easy to store. Here's how the Vax, Shark and Dyson weigh up:

The winner: The Dyson V11 Absolute is the lightest of the bunch and the wall-mounted charger is super convenient

Which should you choose?

• It's the priciest of the bunch, but for great runtime, ease of use and lightweight design, the Dyson V11 Absolute is definitely worth the investment.
• If you're on a tight budget then you can't go wrong with the Vax Blade 2 Max, which has consistent suction, exceeds its stated run time and is the easiest to empty.
• If you don't want to mount your cordless vacuum on a wall and the idea of a flexible neck that makes it easier to clean underneath furniture appeals, then go for the Shark DuoClean with Flexology.
