Buying a carpet cleaner: which features really matter for carpets, sofas and cars

A carpet cleaner can lift spilled drinks, pet hair, food and everyday dirt from fabric surfaces. But not every machine is right for every home. Some models are advertised with high suction figures but have small tanks. Others have a spray function, but can be awkward to clean after use.

Before buying, it’s worth looking out for these three common pitfalls:

  • High Pa figures alone don’t tell the whole story: cleaning performance also depends on the brush head, water flow, airflow, and the condition of the hose and filter.
  • Small tanks can make the job take longer: when cleaning large carpets or several upholstered items, you’ll need to top up the clean water and empty the dirty water more often.
  • Not every fabric surface is suitable for wet cleaning: delicate fabrics, certain mattress covers and materials that aren’t colourfast can be affected by water and cleaning products.

The most important things to consider when buying a carpet cleaner

1. Spraying, brushing and suction

A carpet washer with a spray function is handy for deep-cleaning carpets, sofas or car seats. It applies water or cleaning solution to the surface, loosens dirt with a brush, then sucks the liquid back up.

This 3-in-1 function is different from that of a conventional carpet vacuum. A dry carpet vacuum mainly picks up loose particles, crumbs and pet hair. A wet vacuum or upholstery cleaner, by contrast, uses liquid and is designed for stains and spilled drinks.

It’s important not to soak the cleaned area. Moving slowly while vacuuming can help remove as much moisture as possible. Follow the manufacturer’s guidance on the maximum water temperature and suitable cleaning products.

2. How to assess suction power realistically

Figures such as 12,000 Pa, 13,000 Pa, 15,000 Pa or 17,000 Pa indicate the stated suction power. They’re useful for a broad technical comparison, but don’t tell you on their own how quickly a sofa or carpet will dry.

Also look at:

  • the shape and width of the suction attachment,
  • the length of the hose and power cable,
  • how easy it is to reach corners, stairs and car seats,
  • whether the airflow can remain as unobstructed as possible,
  • removable tanks and easily accessible filters.

A long hose is particularly useful if you want to clean car seats, tackle stairs or work between pieces of furniture. With a mains-powered machine, you also won’t need to recharge a battery, but you will need an accessible socket.

3. Tank capacity and maintenance

A separate clean- and dirty-water system prevents collected dirty water from being put back onto the surface. Check each capacity separately. Figures such as 1.4 litres of clean water and 1.2 litres of dirty water shouldn’t be treated as a single tank capacity.

After each use, you should:

  1. empty the dirty-water tank,
  2. rinse the tank, brush head and hose as instructed,
  3. allow all the components to dry completely,
  4. check the filter and nozzles for hair or fibres.

This helps prevent moisture from sitting in the machine and can keep unpleasant smells at bay. If you use the cleaner frequently, automatic or manual hose cleaning is also useful.

How to use and care for your carpet cleaner

Before wet cleaning, use a carpet vacuum to pick up loose crumbs and pet hair. Test the cleaning product and the fabric’s water resistance on an inconspicuous area first. Move the brush head slowly and avoid using too much liquid.

When using electrical appliances:

  • Unplug the machine before filling, emptying or cleaning it.
  • Don’t immerse the main unit, cable or plug in water.
  • Don’t pick up flammable liquids, hot substances or sharp objects.
  • Allow the tanks and filters to dry after use.
  • Keep children and pets away while the machine is running.

Frequently asked questions about carpet cleaners

How often should you use a carpet cleaner?

It depends on the material, how often it’s used and how dirty it is. For individual stains, spot cleaning is usually enough. Sofas, carpets or pet areas that see heavy use can be cleaned more often when needed. The key is to let the surface dry completely between uses.

Can you use a carpet cleaner on car seats and mattresses?

Many portable models are designed for car seats, upholstery and mattresses, according to their product descriptions. First, check whether the fabric in question is water-resistant. Use only a small amount of liquid on mattresses and make sure the room is well ventilated.

How much does it cost to run a carpet cleaner?

Running costs include electricity, water and, where needed, cleaning solution. For mains-powered machines, you can make a rough estimate of electricity use from the stated wattage and how long you use the appliance. A larger tank can also mean fewer refills, but it won’t necessarily use less cleaning solution.
