Blocked filters, a complete loss of suction or a faulty battery are the most common cordless vacuum problems according to our survey of 1,649 cordless vacuum cleaner owners in the UK. 

Knowing which brands develop the most faults and how quickly is vital when you're buying a new vacuum cleaner. That's why each year we ask nearly 10,000 Which? members to tell us whether they are happy, or have experienced problems with their home appliances, in our unique reliability and customer satisfaction survey.

Our survey data takes into account the number and severity of reported faults, and how soon they happened after buying. We've got data on all the biggest cordless vacuum cleaner manufacturers – including Dyson, Bosch, Vax, and Gtech - so we can tell you which brands are worth buying - and the ones to avoid.

Cordless vs corded vacuums: which are more reliable?

In general cordless vacuum cleaners are less reliable and develop faults sooner than traditional plug-in vacuums. If reliability and longevity is number one for you, it's worth considering the most reliable corded vacuum cleaner brands, as our data suggests that these will outlast even the most reliable cordless vacuum cleaners, and they're usually cheaper too.

Preventing faults: what you can do

Regular maintenance will go a long way to keeping your vacuum fault-free, and it's even more crucial with cordless vacuums, which need more frequent maintenance due to the smaller dust container. See our guide to maintaining your vacuum cleaner for a step by step guide, with video, on how to keep your vacuum from blocking up and losing suction. 

Best vs worst: cordless vacuum cleaner brands compared 

As the table reveals, some brands are much more reliable than others, and leave customers more satisfied.

Common cordless vacuum cleaner problems 

The most common problem people experience with their cordless vacuums is blocked filters. The good news is that this is an easy problem to fix with regular maintenance and cleaning of both the allergy and motor filter on your cordless vacuum cleaner. 

A complete loss of suction is the next most common fault, which can either be a symptom of blocked filters / a clogged brush bar on the floorhead, or a more serious issue like a faulty motor or blocked passages within the vacuum.

A faulty battery is a more serious problem. With some cordless vacuums, it's impossible to replace the battery, so once it goes, the whole product is useless. It's worth checking if the battery can be replaced, or looking out for a model with swappable batteries - as this can buy you more cleaning time too, though spares often cost £50 or more, so can be an expensive extra.

How we measure cordless vacuum cleaner reliability

When calculating reliability, we categorise and take into account minor, major and catastrophic faults:

  • Minor fault - a fault that doesn't affect the product's performance significantly or a fault that only occurs occasionally with minimal impact. This issue may be irritating or annoying but it isn't frequently problematic and you can easily work around it. For example, if an accessory you don't use very often breaks.
  • Major fault - a fault that has a noticeable effect on the product’s performance. This fault affects how you use the product and can be problematic. For example, if the battery life dramatically shortens over time.
  • Catastrophic fault - a fault that renders the product unusable, with the fault needing to be repaired or parts replaced before it can be used again. For example, the vacuum cleaners motor might cut out intermittently, or not turn on at all.

How we calculate the best and worst cordless vacuum cleaner brands 

Every year, we gather a wealth of information about Britain's favourite vacuum cleaner brands, both cordless and corded, through our independent testing and a survey of Which? members about the products they own. 

We crunch the numbers from our tough cleaning tests, where we test all the major cordless vacuums launched each year, to see how each brand fares on average. 

We also ask members to tell us how likely they would be to recommend a brand, based on the products they own, and how reliable they are. This year nearly 10,000 Which? members told us about more than 30,000 products. We calculate a brand's reliability and its customer score based on the results of our annual survey.

Our reliability survey, combined with our testing data, means we can give unique insight into which cordless vacuum cleaner brands are a good bet.

This data is crucial for our testing, too. If a brand falls far below the category average, we won’t recommend any of their products unless a marked improvement in reliability is shown, or the brand offers an above-average guarantee on a product that qualifies as a Best Buy based on our cleaning tests.
