Based on a recent study by COIT Cleaning and Restoration, the best-rated carpet cleaner is the Hoover Power Scrub Deluxe Carpet Washer. The number-two rated carpet cleaner is the Bissell DeepClean Pet Deep Cleaner 36Z9, which specializes in pet stain and odor removal.
As of 2015, the Hoover Power Scrub Deluxe retails for $160. COIT drew attention to many positive features of the cleaner including its adjustable height, separate gallon tanks and automatic shut-off when tanks are full. The only shortcoming COIT noted is a short power cord.
The Bissell DeepClean is priced at $300. It comes with a removable pet hair basket and has adjustable settings. However, like the Hoover Power Scrub Deluxe Carpet Washer, it has a short power cord.
