The Advance SC750 REV 28-inch autoscrubber features 2, 14-in dual random orbiting (2,250 orbits/minute and a 10-RPM 2nd orbit) scrub heads that have the ability to clean in four different and distinct cleaning modes. The SC750 REV's two 14-in pads provide consistent contact across the cleaning path and feature an orbital motion that spins at 2,250-RPM. These orbits attack the dirt from multiple directions, and hold the cleaning solution in the full area of the pads, compared to traditional rotary scrubbers that sling water away from a round pad. The SC750 REV 28-inch can clean chemical free with just plain water. The REV has the ability to damp strip VCT or Terrazzo floors without using chemicals. It can clean with detergent utilizing the dashboard mounted detergent on/off button for variable dilutions. The 21 gallon solution and recovery tanks provide long continuous cleaning times with reduced trips for dump and refill. 310 Ah batteries for long run times between recharging.
