Hardeep ChannaResearcher & writer

Inconsistent performance and leaks are just two of the most common faults reported by steam cleaner owners in our unique survey. Read on to find out which steam cleaner brands customers would recommend.

Knowing which brands are more prone to faults is vital when you're buying a new steam cleaner. In our latest customer satisfaction survey, we asked more than 6,997 Which? members, as well as 3,003 members of the public, to tell us whether they're happy with their steam cleaner and if it's given them any trouble. 

We've crunched the numbers for the biggest manufacturers – including Bissell, Karcher, Shark and Vax – and have calculated a customer score for each, so you know which brands come recommended by owners. Our survey data takes into account which steam cleaner brands had faults reported, and whether they needed to be repaired or replaced.

The 3 most common steam cleaner faults

1. Inconsistent performance (13% of all faults reported)

Gradual deterioration in performance of your steam cleaner could be down to several factors. 

Some can be quite basic, like lack of water in the tank, a blockage or the water tank cap not being securely fastened. All of these are relatively easy to fix yourself with the help of the manufacturer's guide. 

Always check the safety latch is not locked, as this will prevent the steam cleaner from functioning. Make sure you regularly clean (or if needed, replace) the water filter, as it can become clogged over time.

If your unit is performing inconsistently or not up to standard and none of these apply, check your warranty to see if you can get the product fixed or replaced by the manufacturer. Alternatively, take it to a specialist at an approved repair centre.

2. Leaking/spitting water (12%)

Leaking is a common steam cleaner problem, but the good news is there are a few checks you can make in order to identify the cause of leaking and fix the issue.

If your steam cleaner is spitting water, chances are the water tank has been overfilled. If the tank is filled to a good level and the appliance continues to leak, check the tank, cap and the filter for damage. 

Also, make sure the water tank is fitted correctly and pushed into the unit securely, as a loosely fitted tank may leak.

If the filter or another part of your steam cleaner is damaged, contact the manufacturer to find out if a replacement part might be covered under your warranty.

3. Body cracked or damaged (11%)

Just over 24% of owners of steam cleaners reported the this fault, and stated that they had their product repaired or replaced by the manufacturer. 

If your appliance is still under warranty, try to get it repaired or replaced before purchasing a new product, as this can save you having to spend unnecessary money.

How we calculate the best and worst steam cleaner brands 

Which? has a wealth of information on Britain's favourite brands. Every year we ask Which? members to tell us about the home appliances they own – from how likely they would be to recommend a brand, to how reliable the products are once they get them home.

Last year 6,997 Which? Connect panel members and 3,003 members of the public told us about more than 20,454 individual products. We calculate a brand's customer score, fault rate and proportion replaced or repaired based on the results of our annual survey.

Our surveys, combined with our extensive lab tests, mean we can recommend the best steam cleaners to buy.
