World’s quietest vacuum cleaner

The AEG-Electrolux Ultrasilencer is designed to work quietly without compromising cleaning performance.

Which? vacuum cleaner expert Vivienne Fitzroy says: ‘In the past we’ve recorded noise levels of up to 90 decibels for some vacs in our lab tests – equivalent to a symphony orchestra performing a loud passage. 

‘At 66 decibels the Ultrasilencer certainly lived up to the hype in our tests. It’s the quietest we’ve seen in recent years – but you’ll need to check out our full review to see if it’s as good at cleaning as it is keeping the noise down.’

Best Buy vacuum cleaners

We put all our vacuum cleaners through rigorous independent tests at our lab, before posting results to our vacuum cleaners review. We test how good they are at cleaning carpets, wooden floors and pet hair.

We only award Best Buy status to those that deliver the best cleaning results and have average or above reliability. 

We score each brand for reliability by surveying thousands of Which? members every year to find out which brands are the least likely to suffer problems after you get them home.
