The ONEPWR CleanSlate is a cordless, battery-powered spot and upholstery cleaner built around Hoover's 20V ONEPWR battery. It sprays and extracts on carpet, stairs, rugs and car interiors, with a 7-inch cleaning width, a 4.5-foot hose and a 40-ounce clean water tank. Boost Mode adds suction for set-in stains, and the removable battery can be swapped for longer jobs. It suits quick spot work and vehicle cleaning rather than whole-room deep cleaning, where a corded extractor with more tank capacity and continuous power does better. Owners like the freedom from cords but rate it only modestly overall, with complaints about suction, battery runtime and durability.

Ratings sit at 3.3 out of 5, so reception is mixed. Owners value the cordless convenience for stairs, upholstery and cars, but many say suction and stain removal fall short of a corded cleaner and that battery runtime and build quality disappoint.
