Best steam cleaner brands
By Sarah Ingrams
Discover the best and worst steam cleaner brands, according to our independent lab tests and surveys of steam cleaner owners.
Since we began testing steam cleaners in 2011, we’ve assessed almost 100 different models in the Which? lab to find out which really offer the best cleaning power and value.
In this guide, we share what we’ve learnt about some of the biggest steam cleaner brands, such as Karcher and Vax. Our insider advice reveals which does well in our tests, which brands you can trust to be reliable – and which you should avoid.
Once you've decided which brand is for you, head straight to our steam cleaner reviews for the inside track on the latest best models.

Choosing the best brand of steam cleaner
If you’ve decided to buy a steam cleaner that can take care of a wide range of cleaning jobs, from floors to windows, then you’ll probably be looking for a cylinder steam cleaner like the ones pictured. A great steam cleaner doesn't just deliver a great clean with minimal effort each time, but it should be a model you can rely on and ideally one that you'd be happy to recommend to a friend.
Our brand overview takes all of this into account – including our rigorous test results as well as feedback from hundreds of Which? members who own steam cleaners.
Customer scores are based on how satisfied Which? members were with a product, and how likely they are to recommend it to a friend.
We test cylinder steam cleaners from big brands such as Karcher as well as own-brand models to separate those which give a great all-round clean with minimal effort from the steam cleaners which struggle to shift dirt and make you work hard into the bargain.
We also ask hundreds of Which? members who own steam cleaners to tell us how happy they are with the brand they own, enabling us to give a Which? customer score. The most popular brand of cylinder steam cleaner gets a customer score of 65%, and the worst 54%. We also ask about any problems they have experienced with it we can calculate its reliability rating.
