Description
High-traffic logistics corridors and healthcare facilities demand quiet, chemical-metered disc scrubbing with rapid turnarounds. The Nilfisk SC550 R 20 20″ walk-behind scrubber features a 20-inch disc deck powered by 24V lithium technology and EcoFlex proportioning. You steer dual 13.2-gallon tanks with motorized traction. However, this single-disc machine cannot pick up dry wood splinters.
The machine framework incorporates a structural steel chassis and thick rotationally molded high-density polyethylene solution and recovery tanks. A transaxle drive motor propels forward motion, while a 0.6 HP electric motor powers the single 20-inch disc brush at 160 RPM. Operators command up to 66 lbs down-pressure. Polyurethane wheels transport an empty weight of 250 lbs without marking finished floors.

Dynamometer Bench Testing Load Telemetry
Bench testing confirms continuous motor current draw of 24-Amps at 24V under maximum disc down-pressure and traction drive engagement on industrial concrete. The lithium battery maintains constant voltage discharge across two continuous hours without power taper. The 0.4 HP two-stage vacuum system produces 45 inches water lift at the recovery hose intake. Single-pass water recovery measures 98% on flat commercial tiles. Acoustic telemetry records a quiet 63 dBA sound level at the operator station. Scrub motor heat rises 28°F.
Field Operation Usability Maintenance Directives
Janitors control this machine using the ergonomic handle console and variable-speed thumb switches. The traction drive handles slight hallway inclines without operator pushing effort. Do not deploy this 20-inch disc scrubber for rough outdoor concrete slabs, asphalt parking decks, or loose debris sweeping.
- Flush the automated EcoFlex chemical proportioning plumbing every 30 days.
- Examine disc brush bristles for wear every 100 operating hours.
- Flush the 13.2-gallon recovery tank with clean water after each shift.
