The Hydramaster RX20 is a corded scrubber and buffer designed for tile and grout, concrete, and stone surfaces. It operates at 110V and features a walk-behind style, making it easy to maneuver around the workspace. The RX20 model includes a disc brush and pad type for efficient cleaning and polishing. Ideal for business and industrial cleaning applications, this Hydramaster unit provides reliable and effective floor and upholstery cleaning solutions. It has been in the garage for two years, so it is a little dusty, but still functional and well cared for.
