At 1.5 hp and 175 RPM, these floor machines are the smoothest operating in the industry. Contractors and floor technicians prefer this machine for their easy start up. Our floor scrubbers feature a patented rotationally molded housing that absorbs the shock and torque normally associated with running a floor machine. The ultra high output 1.5 hp motor provides the power to maintain the speed necessary for the tough floor cleaning jobs and start up where heavier torque is required for stripping, scrubbing, scraping, grinding, shampooing and bonnet cleaning. The 20" 1.5 hp Floor Machine combines the enduring popularity of an all metal floor machine with the most technologically advanced motors, transmissions and electrical components. You get the craftsmanship of the classic metal floor machine with the dependability of all metal construction and the features for the most challenging floor jobs.
