Advance SC450 56383129 20″ Walk Behind Floor Scrubber with (2) 98 Ah Gel Batteries, Charger, and Brush – 10.5 Gallon / 11.9 Gallon

Description

Scrub commercial clinic hallways and classroom vinyl tile without battery acid hazards using this Advance SC450 56383129 20″ Walk Behind floor scrubber. Powered by two 12V 98 Ah maintenance-free gel batteries, this 24V machine cleans a 20-inch path at 150 RPM. Operators must sweep entrance sand before scrubbing to protect the recovery squeegee from premature tearing.

Thick rotationally molded polyethylene forms the 10.5-gallon solution and 11.9-gallon recovery reservoirs, resisting impact damage and harsh chemical degreasers. A powder-coated steel frame carries the sealed gel battery bank, 400W brush motor, and 330W vacuum motor. The 20-inch disc scrub head applies 65 lbs of down-pressure across uneven floor joints. The machine weighs 285 lbs with batteries.

Bench Dynamometer Load Electrical Telemetry

Technicians test each SC450 gel scrubber on our diagnostic platform to verify vacuum water lift and electrical draw under load. The 330W vacuum motor produces 45 inches of sealed water lift through the recovery dome. Brush motor current draws 14-Amps at 24V under full 65 lb down-pressure on commercial VCT tile. The 98 Ah gel battery bank maintains stable discharge voltage across two continuous hours. Sound meters record 68 dBA.
