We've tested cordless vacuum cleaners from big brands including Dyson and G-Tech

We’ve just tested 14 of the latest cordless vacuum cleaners, including models from Bosch, Vax and Hoover, and uncovered four high-scoring Best Buys and two pitifully bad Don’t Buys. 

Though many of the cordless vacuum cleaners in our latest tests are similar in price, there are significant differences in how well they clean. With scores ranging from an impressive 78% to a dismal 34%, our tests show that manufacturers' claims don’t always stack up.

Find out which came top - and which have been relegated to the Don't Buy pile - in our cordless vacuum cleaner reviews.

Cordless vacuum cleaners on test

Our latest tests have seen seven brands go head to head, including Dyson, Bosch, Gtech, Bissell, Black and Decker, Hoover and Vax. 

We tested three of the latest models from Dyson's V6 range - the top-of-the-range Absolute, the Fluffy and the basic V6 model. Each model in the range has a different combination of attachments and a different price. But is there actually any difference between them in terms of how well they clean? Our test lab reviews reveal all. 

Also having undergone our lab tests is the Gtech AirRam K9, a cordless vacuum designed specially for pet owners. Based on the original Gtech AirRam AR02, this cleaner is designed to remove stubborn pet hair, has zinc alloy components to withstand tougher cleaning jobs, and scented filters to stave off dirty pet smells.

Cordless vacuum cleaning power

In our tests we challenge cordless vacuum cleaners to pick up fine dust ground into the carpet, hidden in floorboard crevices and on laminate flooring. These tests really help to highlight the ones that will banish dust and those that will hardly touch it.

On floorboards, some can only pick up less than 5% of the dust - a huge difference when you consider the best models can collect nearly all of it. On carpet, the worst only suck up less than 19%, while the best can gather more than 75%.

We also put each vacuum cleaner to work removing ground-in pet hair from the carpet, which some really struggle to do, and measure how many dust particles they leak back out - particularly important if you're an allergy sufferer.
