Medium-duty floor pad is designed for moderate wet cleaning and scrubbing with rotary\/automatic scrubbers. Medium-hard resin and medium denier fiber is abrasive enough to take one to two coats of damaged finish off the floor. The pad also removes soil, scuff\/heel marks. Open-web design allows dirt to enter the fiber and resist soil load on the face of the pad for maximum use. Resiliency allows pad to remain flexible to reach depressions. Floor pad is designed for use at speeds between 175 to 350 RPM.
