The Bissell Proheat is a powerful carpet cleaner that is great for busy homes where spills, stains, and pet hairs are a frequent occurence. 

Deep clean for carpets and upholstery

Our reviewer has praised this carpet cleaner's visible cleaning results, including on upholstery and deep pile carpets. It's also very effective at picking up pet hairs (owners of long-haired pets will be particularly thankful).

Spot cleaning for spills and stairs

It can also be used for quick spills and has a tool for furniture and the stairs – all those small spots the bigger carpet cleaners will miss.

Powerful but noisy

The only thing to bear in mind is that all this power comes at the cost of quite a bit of noise.

What is the best carpet cleaner you can buy?

How to buy the best carpet cleaner 

When it comes to buying the best carpet cleaner to suit your needs, there are a few factors worth considering if you're looking to get the most for your money. We'd recommend bearing the following in mind:

Capacity
If you're planning on cleaning a large, completely carpeted home, on a regular basis, or have a lot of carpets to clean – perhaps you're an Airbnb or holiday apartment owner – look for something with a large capacity that won't require constant refills. Similarly, if you're simply looking to clean a small area of carpet on an irregular basis, pick something that's portable and can be stored in a cupboard, with ease.

Cable length
The same things can be said for cable length. The longest cable possible is a must in a large space, but less of a priority in small homes, or where there's only one carpet that requires cleaning, say, in the bedroom. 

Attachments
You'll want to make sure your carpet cleaner does exactly what you want it to do; whether that be cleaning upholstery, stair carpets, car interiors, curtains, and more. Ensure the model you choose comes with the appropriate attachments to get the job done.

Carpet cleaners vs. vacuum cleaners 

Why do I need a carpet cleaner if I already own a vacuum cleaner, you may ask? Two reasons: stain removal and deodorising  action. While vacuum cleaners are perfectly good for everyday cleaning, a carpet cleaner delivers a deeper clean, often with the assistance of a carpet shampoo. Think of it as an 'as well' rather than an 'instead' product.

While we recommend using a carpet cleaning machine to give your soft flooring a new lease of life, for small clean-ups and quick jobs, a carpet cleaning product may just do the trick instead. For all the best carpet cleaning products, see our guide.
