Small, but strong on stains. Years of experience guided the development of Ruby, our compact but brilliantly powerful water-extraction machine. Made specifically for upholstery cleaning, Ruby has a specially engineered reduced-pressure 55-psi water pump and a 1-horsepower vacuum motor that creates cyclonic action. The hand tool's clear vacuum head makes it easy to see the stains and dirt as they're vacuumed away. Features a 3-gallon solution tank and a 3-gallon recovery tank.
