This carpet and upholstery cleaner removed stains faster and more thoroughly than any other model, thereby earning The Best rating from the Hammacher Schlemmer Institute. The Best model removed every last drop of grape juice and coffee from carpeting with only two passes, unlike lesser models that failed to completely remove the stains after four passes. It has a 13 1/4"-wide cleaning path (the widest of all models tested) and uses hot water, detergent, and dual multidirectional brushes that surround carpet fibers to remove dirt from every angle. Unlike lesser models that left behind soapy residue, The Best model quickly suctioned all of the dirty, soapy water and applied direct heat to the cleaned carpet to hasten its drying. Its upholstery tool has a rotating brush that was gentle on fabric yet quickly removed stains, while lesser models leaked or oversaturated upholstery. The Best model used the least amount of detergent while achieving superior results, and its water tanks were the easiest to remove and refill. Includes 16 oz. of detergent. 44" H x 15" W x 20" D. (28 1/2 lbs.)
