Buying a Carpet Washer? Read This Buying Guide First

Carpets get a rough deal, don’t they? They’ve got to take the brunt of constant footfall and heavy furniture, all while looking as smart and fresh as the day they were installed.

Thankfully, there’s a way to help them out: the handy carpet washer. These clever pieces of equipment can dredge even the toughest marks and stains, but if you’re wondering whether a carpet washer is the sort of appliance that belongs in your cupboard of occasional miracles, you’ve come to the right place. 

In this guide, we’ll cover everything you need to know about carpet washers, and offer our top recommendations. Keep reading to learn more…

What is a carpet washer?

The clue is very much in the name. 

A carpet washing machine is a household appliance that does what a vacuum alone cannot. It deep‑cleans fibres by applying a cleaning solution, agitating the pile, then extracting the dirty water back into a separate tank. 

Think of it as a portable, scaled‑down extractor designed for occasional but effective stain and freshening work around the home.

The basic cycle is simple. You pour a cleaning solution into the machine’s clean water tank, apply it to the carpet or upholstery, let a brush or roller agitate the fibres to loosen dirt and stains. 

The unit sucks up the slurry of solution and muck into a dirty water tank, leaving your carpet fibres visibly cleaner and, importantly, with less trapped odour.

A good machine removes spill marks, ground‑in dust in high‑traffic strips, and pet‑related soiling without the time or cost of booking a carpet cleaning specialist. They can also tackle stairs, sofas, and car interiors, were lugging a full‑size extractor would be a touch overkill.

Sounds great, right? But carpet washers do have limits. 

They are designed for domestic use and periodic deep cleans rather than continuous, commercial extraction. They won’t magically restore very old, badly matted carpets to showroom condition, but they will considerably extend the time between professional cleans and make spot maintenance simple and effective.

When used sensibly, a carpet washer is the kind of appliance that turns an anxious “oh no” spill into a ten‑minute job and keeps your soft furnishings smelling and looking fresher.

What to look out for when buying a carpet washer

When selecting a carpet washer, you want to match the machine’s practical features to how and where you’ll use it. 

Don’t be dazzled by technicalities. Focus on capacity, reach, cleaning action and upkeep. Here are the features that we think you should look out for to determine how useful a carpet washer will be in your home:

Tank capacity 

We can split this first consideration into two categories: clean water, and dirty water.

Let’s start with the clean water tank. The larger the tank, the more water it will hold, which means fewer top‑ups during a session. 

A 2.5 L tank is a sensible domestic size, big enough to clean an average living room without the need for constant refills, yet small enough that the machine stays light and manoeuvrable. 

The same logic applies to the dirty water tank. This tank keeps extracted muck out of the clean solution, and is hygienic. 

These tanks tend to be a little smaller than the clean water tank, and will typically fill faster than the clean tank because extracted water contains soil, so expect to empty this once or twice during a substantial cleaning session.

Top tip: plan cleaning runs room by room and reserve heavy pre‑treating for the worst patches to make the most of the water you carry.

Power and performance

What good is a carpet washer if it lacks the power to suck up that much?

Motor wattage is an indicator of what suction and agitation energy you can expect to get out of your carpet washer. For household stain work, a motor in the range of 800W gives a good balance, enough pull to extract solution and loosen dirt without being noisy or power‑hungry. 

Top tip: higher wattage isn’t inherently better for household needs, so don’t rush in with the highest power model you can find. Efficient extraction, brush action, and correct technique matter just as much.

Tools and reach

Power is only one component of a good carpet washer. It also needs to clean properly.

Let’s start with the part that gets down in the dirt, literally. A wide cleaning head covers more carpet with each pass, speeding up the job. 

A roller brush that detaches makes maintenance simpler, so you can remove hairs, threads, and debris that would otherwise reduce effectiveness. 

Brush agitation works by loosening soil, so the extraction can do its job, so a sturdy, serviceable brush is worth paying attention to.

The hose length determines how far you can go without repositioning the base unit, so you want one with a reasonable reach that extends the machine’s usefulness to sofas, staircases, and car interiors. 

A long hose makes the difference between a carpet washer that cleans floors and one that becomes a genuinely multi‑purpose home cleaner. 

This logic applies to the power cord as well. A long power cord gives practical reach in household rooms so you spend less time swapping sockets. If you have multiple rooms or awkward stair layouts, a long cord reduces interruptions.

Top tip: to make sure your carpet washer has a reasonable reach, we recommend looking for models with a hose of over 2 metres, and a power cord over 7 metres.

Water and solution flow

Being able to control how much solution the machine lays down is very useful. Carpet cleaners require a cleaning solution, so you want to make sure you get the most out of it for your money, and the health of your carpet. 

Lower flow settings are kinder to delicate fibres and speed drying, while higher flow helps tackle stubborn stains.

Top tip: use the minimum effective amount of cleaning solution and make additional passes with extraction rather than soaking the pile.

Portability and maintenance

What good is a carpet washer if you struggle to manoeuvre and maintain it?

Weight is always going to be the trade-off when you look for models with larger tanks and cords, so finding the right balance that works for your needs is crucial.

A unit weighing around 3 kg is easy to lift between floors and use on stairs. Compact dimensions make storage simpler and mean the machine won’t dominate your storage cupboard. 

Cleaning the cleaner is another consideration. Carpet washers will need a thorough clean after use if you want it to work properly (which we assume you do if you’ve bought it).

Look for easy‑access tanks and detachable brushes for straightforward cleaning. Rinse both tanks after use, clear the roller of hair and debris, and allow the machine to dry before storing to avoid mould and smells. 

Simple, tool‑free maintenance saves more time over the life of the product than a handful of extra features.

Top tip: bear in mind that tanks add weight when full, so ergonomics and handle design affect real‑world portability.

Our top recommendation for carpet washers

Now with all those considerations out of the way, let’s look at the Morphy Richards’ top recommendation for carpet cleaners.

If your home needs a dependable machine for periodic deep cleans, stain removal and refreshing upholstery, there’s only one carpet washer you should consider: the MRXWASHMAX DualClean Carpet Washer. 

This carpet washer has the practical, user‑focused specifications that will suit the typical UK household. 

The 2.5L clean tank means that you won’t be refilling every few minutes when tackling a lounge or a run of bedrooms, and the 1.6L dirty tank keeps muck separate for hygienic disposal. 

The 800W motor provides enough suction to pull out solution and soil effectively without becoming an unwelcome chore to run. 

The detachable roller brush is an invaluable asset, making it easy to clear it of hair and fibres after use, and keep agitation working at full strength.

The 7.2m power cord and the 2.4m upholstery hose are simple but underrated conveniences, making it straightforward to clean stairs, sofas and awkward corners without repeatedly hauling the main unit. 

The adjustable water/solution flow gives you control when you’re dealing with delicate fabrics or stubborn spills.

Better yet, the 1L bottle of cleaning solution included in the box means you can start cleaning straight away, and the formulation is tuned for the machine’s seals and plastics so you avoid compatibility headaches. 

At around 3 kg and with compact dimensions, the DualClean Carpet Washer is light enough to carry up a flight of stairs when empty, and the modest footprint makes storage easy.

If your priority is a practical, ready‑to‑use machine that will actually be used rather than gathering dust, there is no better option than the MRXWASHMAX DualClean Carpet Washer.
