Deteriorating suction power, blocked filters and batteries not lasting as long as they used to are the most common cordless vacuum cleaner problems, according to our survey of 8,382 cordless vacuum cleaner owners in the UK.

Knowing which brands develop the most faults and how long a model can be expected to last is vital when you're buying a new cordless vacuum. That's why we ask thousands of people each year whether they're pleased with their cordless vacuum, or if they've experienced problems.

We've got data on the biggest vacuum cleaner brands – AEG, Black & Decker, Bosch, Dyson, Gtech, Halo, Hoover, Lidl, Miele, Samsung, Shark, Tineco and Vax – so we can tell you which brands to choose, and which ones to avoid.

The table below summarises this year’s results. Brands are ranked by their customer score, which relates to whether customers would recommend the brand.

The 'proportion faulty' is the percentage that experienced a fault, and the 'proportion repaired or replaced' is the percentage of cordless vacuum cleaners that were fixed or thrown away due to a fault.

The three most common cordless vacuum faults

Cordless vacuum cleaners are less reliable than their corded cousins, but you don't always need to buy a new one if your cordless vac develops a fault. In fact, the three most common faults can be simple to fix.

1. Battery not lasting as long as it used to (22% of all faults reported)

Like most lithium-ion batteries, cordless vacuum batteries eventually lose power.

Before buying a new vac, it's worth checking whether the battery can be replaced – spare batteries can buy you more cleaning time too, although they often cost £50 or more, so they can be an expensive extra.

2. No suction or deteriorating suction (12%)

A complete loss of suction or noticeably deteriorated suction could be a result of reduction in battery power, blocked airways or filters within the vacuum cleaner, or a clogged brush bar.

To find out how to restore suction in your cordless vacuum, watch our video guide on how to fix a vacuum cleaner that's lost suction.

3. Blocked filters (11%)

Blocked filters can be avoided by regularly washing your vacuum's filters. Most manufacturers advise rinsing filters in cold water once a month and allowing them to dry for up to 48 hours on a windowsill.

Washing your filters with warm water or not letting them dry could damage your vacuum's filtration system, allowing fine dust particles to escape while you clean.

How we calculate the best and worst vacuum cleaner brands

Which? has a wealth of information on Britain's favourite vacuum cleaner brands. 

Each year, we ask Which? members and the public to tell us about the domestic appliances they own – from how likely they'd be to recommend a brand, to how long a product lasted once they got it home. 

This year, more than 17,000 people told us about more than 70,000 products, including 8,382 cordless vacuums

Our survey, combined with our independent testing data, means we can give you unique insight into which cordless vacuum brand you should buy.
