A compact 20 in disk scrubber for tight floor plans
The Timberline S20 Disk Pad Assist is a small-footprint, battery-powered walk-behind floor scrubber for spaces where a bigger machine gets in the way: auto shops and showrooms, school locker rooms and convenience stores. Timberline sizes it for areas under 25,000 sq ft and rates it at 15,748 sq ft per hour theoretical productivity.
A single 20 in disk brush scrubs while a 33 in squeegee and a 0.8 hp, 3-stage vacuum motor with 50 in of water lift pick up the water. The 12 gal solution and 15 gal recovery tanks are 5/16 in poly on a 3/16 in powder-coated steel chassis, and it works on concrete, epoxy, grout and VCT.
Condition: Demo. Inspected by SES technicians.
