There are just a few carpet spot-cleaner machines on the market, and the highest Amazon.com user ratings go to the Bissell carpet cleaning machines. The units researched have several things in common: they really are spot cleaners, meant to clean very small areas; they lack the rotating-brush and suction power of full–size machines; and, although they can be used to clean upholstery, users find them awkward and cumbersome for this purpose. That said, all three carpet spot cleaners seem to perform well for their intended uses.
With Sixty-four percent of Bissell SpotBot consumer reviews on Amazon.com giving this machine five stars out of five, the Bissell SpotBot takes first place. It boasts “WalkAway” technology that allows the machine to clean carpet stains unattended when it’s placed on top of the spot and set to the “set-in stain” option. Users report the SpotBot does an excellent job at removing stains, whether the automatic “set-in staine” setting or the manual setting is used. They note, however, that the automatic setting uses a lot of cleaner and leaves a distinct circle on the carpet where the round scrubbing brush cleans the stain. Some users surmised that the cleaning may have taken some color out of the carpet, but most agreed that the color difference is due to the area surrounding the circle being dirty. “Clean circles” notwithstanding, the Bissell SpotBot reportedly is highly effective at removing stains.
The Bissell Spot Lifter is the only battery-powered machine researched. Although Bissell claims it runs for 15 minutes between charges, users report that five to 10 minutes is more accurate. That apparently is sufficient for most spot removal, as 49 percent of Amazon.com user reviews give Spot Lifter five stars. The main drawback of this machine compared to the others is that it doesn’t have a rotating brush. It does have a stationary one that users report as effective, however, as they note the machine does an excellent job at removing stains. On the downside, when the dirty-water tank is overfull, soiled water leaks into the unit and sprays out the side vents. Users claim these leaks can be prevented with frequent emptying of the tank.
Almost 45 percent of Amazon.com user reviews rate the Bissell Little Green ProHeat five stars out of five, it’s clear that the machine is very good at carpet spot removal. The Little Green is a one-step spot cleaner that distinguishes itself by heating the water in the clean-water tank before it sprays it onto stains. The other bonus is the turbo brush, which is reported by users to be a rotating brush with a suction-mode switch. The Little Green has both suction and clean modes. The primary complaint about the Little Green is that the spray trigger malfunctions frequently because of a build-up of deposits caused by the cleaning fluid and water mixture passing over the heating unit and burning. Several users reported the need for frequent repairs, although others have been able to keep their sprays clear by carefully cleaning and flushing the machine after each use. On the upside, users rave about the the Little Green’s cleaning power.
