The Windsor® Grouthog® is designed specifically to clean hard tiles and their grout lines quickly and efficiently. The Grouthog is driven by a 1/3hp motor that is thermally protected to ensure long, trouble-free performance. Its weight is concentrated over the brush for maximum cleaning efficiency, yet at only 49 pounds, it is light enough to control in confined areas. The adjustable handle and 40 foot cord ensures ease of operation. The Grouthog uses a cylindrical rotating brush to remove dirt from grout lines while also cleaning the tile surface. Grouthog is perfect for concrete floors and docks, or for stripping finish from all types of hard surface flooring. An optional four gallon tank with convenient solution release trigger is available for use with the Grouthog.
