The best carpet cleaners in the UK – tested on coffee, curry and red wine stains

I’ve tested a few carpet cleaners in my time, but I have to admit I learned new things putting these eight models through a series of punishing tests. My main takeaway is this: if you have light-coloured carpet, don’t eat curry over it. If you do, and the worst happens, clean it up as quickly as you can, because every second counts.

I also learned that no carpet cleaner in this group comes with a magic wand you can wave over a mess to make it disappear. I doubt there’s a machine on earth that can make a single pass over a dollop of tikka masala paste and leave no trace of it behind.

Don’t let this put you off, though. All the machines I’ve tested here put up a good fight against a variety of stains. Just be warned that even with the very best carpet cleaner, you’ll need to add time, elbow grease and persistence if you want a carpet that looks as good as it did before the mess hit the floor.

Why you should trust me

While I’ve spent more time in the past few years testing vacuum cleaners (even my kids call me “the Hoover reviewer”, not least because they know how much it annoys me when they use a trademark as a generic term), I’ve also worked with a good number of carpet cleaners. I’ve reviewed enough of them to be known to my neighbours as someone who might have a carpet cleaner on test that they can borrow, particularly when their carpets have been subjected to a teenager’s house party, a toddler with a stomach bug or an incontinent pet.

Beyond cleaning, I’ve been testing all sorts of products for more than 30 years, from laptops and printers to smartphones and video doorbells.

How I tested

Before handing me the task of testing carpet cleaners, the Guardian asked a professional for five of the hardest substances to remove from carpet. They came back with curry, coffee, red wine, soot and urine. No way was I going to drop any of that on to my own carpets, so I bought two rugs to test on: a relatively short-pile Seattle washable rug from the Range and a longer-pile Marvel shaggy washable rug from Dunelm.

I started with the four full-size cleanersspreading measured quantities of the five substances across the two rugs. I was asked to test them with dried-in stains, so I left them overnight. Don’t do this at home; you’ll end up with a foul-smelling house and stains that are very hard to remove.

I passed the full-size cleaners over each of the stains multiple times in an attempt to get the mess out. Urine wasn’t that visible, but the curry was particularly bad, leaving the espresso, spoonful of soot and measure of Waitrose’s cheapest red somewhere in between.

Where the upright cleaning action struggled, I went on to test their built-in spot-removing tools, in an attempt to get deeper into the stains. I also tested all the full-size cleaners on a larger section of my own carpet, to get a feel for their general cleaning abilities.

To test the four spot cleaners, I used the same problematic substances, but I cleaned these up as soon as they were spilt, as these devices are designed to be ready to whip into action as soon as a mess is made.

Any test products not returned to the manufacturers will be deep-cleaned and donated to the British Heart Foundation.

What you need to know

What type of carpet cleaner should I buy?

That depends on how you plan to use it. Upright cleaners are best for washing all the carpets in your home, and can cover large areas with minimal fuss. Most can be pushed around just like a vacuum cleaner. Many uprights can also spot clean stairs and upholstery with the included handheld attachments, and they’re useful if you need to focus on a small problem area.

If you don’t have a lot of carpet, a dedicated spot cleaner can do a similar job. There’s nothing stopping you from using a spot cleaner on a large area of carpet, but it will take more time and require you to get on your hands and knees. Spot washers are smaller, making them more convenient to store and easier to get ready as soon as an accident happens.

What’s the difference between a carpet cleaner and a steam cleaner?

Most carpet cleaners use clean water and detergent to wash the carpet and have a suction function to take the dirty waste into a separate container. Steam cleaners use water heated to high temperatures to help kill germs and are more often designed for use on hard floors. They don’t tend to suck up excess water afterwards, but because the water is applied as steam, they generally leave less moisture behind.

Should I just rent a carpet cleaner?

Renting a carpet cleaner is a great idea. Most people won’t need to wash their carpets every week. You could consider buying a spot washer for tackling small accidents, but rent a full carpet washer when you want to clean the whole house.

Rug Doctor specialises in cleaner hire and rents out professional-grade machines. Stock is conveniently managed through retailers including Tesco and B&Q, meaning cleaners are easy to collect and return. Tool hire services such as HSS also offer carpet cleaners for rent. You may also be able to borrow one from a local Library of Things.

How often should you clean your carpets?

That depends on how quickly they get dirty. If your footfall is relatively low and you don’t have any pets, then a wash every 12-18 months should be fine. If your carpets see a lot of dirt, though, they might benefit from a more regular clean. Washing carpets with mechanical cleaners can cause wear, so you shouldn’t do it more often than you need to.

Does it matter what my carpet is made of?

Yes. If your carpet is made of delicate or natural materials such as wool, you should check the manufacturer’s guidelines. Some explicitly advise against using their products on particular types of carpet.

How do you recycle an old carpet cleaner?

Some manufacturers, including Vax and Rug Doctor, operate a take-back scheme, where you can buy a new device and they’ll take the old one you’re replacing and recycle it. Some retailers, including Currys, Argos and B&Q, offer a similar service.

If you miss the return window or don’t want to replace your old carpet cleaner, you can take the machine to a council-run recycling centre or another electrical recycling point. Manufacturers help fund the collection and recycling of electrical items through the government’s Waste Electrical and Electronic Equipment (WEEE) regulations.
