New Advance SC500 X20D EcoFlex Small Scrubber
Our Take (from the SES Sales Team)
"The Advance SC500 has been a staple in the Nilfisk/Advance fleet for some time. This affordable, reliable, efficient, and versatile machine is one of the best on the market. It cleans approximately 25,000 square feet of flooring day in and day out. Use a brush on concrete or a pad holder and pad for VCT and other sensitive materials. With a 12 gallon solution and recovery tank, you can go a long way without filling or dumping the scrubber. Nilfisk is an international company and parts/service are available in most areas. New or reconditioned, you cannot go wrong with this machine."
A 20-inch traction-drive scrubber with EcoFlex™ on board
The Advance SC500™ 20D EcoFlex is a compact, quiet, battery-powered walk-behind floor scrubber with traction drive and a 20-inch disc deck. Advance designed it to raise productivity and lower total cleaning costs in hospitals, schools, offices, supermarkets, shops, sports centers, restaurants, hotels and production floors. Large 12-gallon tanks and SmartFlow™ technology extend the time between dump and refill cycles by as much as 50%, and the EcoFlex system installed on every package here lets the operator match water and detergent use to the job. Quiet Mode™ drops the sound level to 60 dBA for daytime cleaning.
