How we test Dyson vacuum cleaners

We've tested 34 Dyson vacuums over the past three years and put each and every one through the same battery of tough tests as we do models from all the brands. By testing each model in the same robust way we're able to accurately compare different models and and brands to ensure we only recommend the very best as Best Buys.

We score each vacuum cleaner on the areas that matter most to you, including how well they pick up dust and pet hair, how much dust they can hold before they need emptying, how easy to use they are and how noisy they are. 

For our dust pick up test a machine spreads very fine sand over a carpet and grinds it in. We then strap the vacuum cleaner to our custom-built test rig, which pulls and pushes the vac as it sucks up the dust. This is known as the Arizona sand test. 

This test is repeated several times; when the bag or canister is empty and also when it's filled with 100g and 400g of dust. A poor vacuum cleaner would pick up less than half the dust, a Best Buy vac can pick up twice as much. 

We also check each vac's pet hair pick-up by hand-combing cat and dog hair into carpet and then testing how long a vac takes to pick it up. We also measure dust capacity - so how often you'll have to empty it - and the weight and reach. 

As well as testing vacuum cleaners in our lab, we also survey thousands of vacuum cleaner owners every year about any faults or problems they've encountered with their vacuum cleaner. The results enable us to apply a reliability rating to each brand - find out Dyson’s reliability track record by taking a look at the results of our vacuum cleaner reliability survey
