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 in orbital walk-behind that scrubs daily and strips finish without chemicals
The Advance SC500 X20R is a compact, quiet walk-behind floor scrubber for hospitals, schools, offices, grocery and retail stores, athletic facilities, restaurants and hotels. Its REV orbital deck spins a 20 in pad at 2,250 rpm orbital while the pad turns at 30 rpm, and Advance says REV technology allows chemical-free removal of floor finish. 12 gal solution and recovery tanks and a 26.5 in squeegee round out a machine sized for daily scrubbing in occupied buildings.
This configuration (Advance 56383556) includes the EcoFlex detergent system, a 24 V battery system with an onboard charger, and a pad holder.
Condition: Demo. Inspected by SES technicians.
