Buying Guide: Carpet Cleaners

By: Kelly Burgess on April 23, 2018

What the best carpet cleaner has

  • A large tank. A carpet cleaner with a large tank requires fewer refills and can cut your overall cleaning time. Keep in mind, however, that the larger the tank, the heavier the machine will be when it's full.
  • Extra tools and attachments. Most upright carpet cleaners and some compact models come with an extension hose and handheld attachment for cleaning upholstery, stairs and narrow places. One in this report comes with a detachable, portable cleaner.
  • Powered brushes to scrub out dirt. Reviewers almost universally agree that carpet cleaners with powered brushes do a better job of scrubbing dirt from carpet fibers. The alternative is scrubbing at the stains with a manual attachment.
  • Powerful suction. If your carpet cleaner can't retrieve all the water it just sprayed on the carpet, your floors will take a long time to dry and they'll probably still have some dirt mixed in with that water, too.
  • A long cord and hose. The longer the cord, the larger the area you can clean without having to unplug and relocate the cord. The best carpet cleaners we reviewed have at least a 15-foot cord and often quite a bit longer. Hoses should be at least 5-feet long to reach even upper stairs without having to carry or balance a heavy carpet cleaner.

Know before you go

Do you plan to clean hard floors, too? If so, you may need to purchase an additional hard-floor attachment for your carpet cleaner. Or, see our report on steam mops.

How much cleaning do you have? If you really have a lot of traffic in and out of your house, quite a few pets, or often have to deal with larger messes, it's worth getting a full-sized carpet cleaner (or even a commercial model like the ones used as rental carpet cleaners) for more thorough cleaning of larger areas. However, if all you need to do is clean the occasional small spill or pet accident, a portable or spot carpet cleaner will be easier to use and store.

Which convenience features are most important to you? You could get by without a clean rinse feature, an internal water heater, indicator lights and automatic shutoff when the recovery tank is full, but all of those features make your carpet cleaning experience easier. Put some thought into what you're willing to pay for, however, as these extras also may raise the cost substantially.

How close are you to a service center? If you need warranty service on your carpet cleaner, some companies require that you take it to the nearest service center, then leave it for repairs. Some frustrated owners report having to repeat a round trip of up to 100 miles to collect their repaired appliance.

A few tips for the best carpet cleaning experience

When it comes to cleaning your carpet, professional carpet cleaning services provide the best results, but they are a more expensive option. They also require you to clear smaller items from every room you want shampooed and adjust your schedule to suit the cleaners. However, professional services give your carpet a true "steam" cleaning and may be able to make even badly stained carpet look a lot better.

Reviewing professional cleaning services is well beyond the scope of this report, because local companies vary, but we recommend checking out Google, Yelp, Home Advisor, or Angie's List for ratings on companies in your area. Angie's List no longer requires a paid subscription to join. A check with your local Better Business Bureau is also a good idea.

It's also important to have realistic expectations when hiring a carpet cleaning service or renting a professional-grade machine. Reviews are often mixed depending upon the condition of the carpet. Some owners report astonishingly good results with rental or professional cleanings, but there is a point at which some stubborn, old stains -- or some very worn down carpets -- are just beyond help. That's another reason why it's best to have a carpet cleaner or spot cleaner tucked into the closet, waiting for your moment of need, to keep your carpet from getting to that point.
