Demo Advance SC4000 28D
Our Take (from the SES Sales Team)
“If you need a rider floor scrubber that won’t break the budget, the Advance SC4000 is a great choice. This machine is available in Disc, Cylindrical, and Nilfisk’s unique REV system, which competes with other orbital scrubbers. This machine comes in 28” and 32”, and yet it is a smaller-profiled machine. This makes it very nimble and maneuverable. Rider scrubbers are not only easier but safer for the operator, as they are not in the way of the machine getting up against walls and making sharp turns because they are seated in the middle of the footprint of the scrubber. All of the command functions are integrated into the steering wheel, allowing the operator to make adjustments on the fly.. Also available are the EcoFlex system and Smart Flow Technology.”
A compact 28 in disk rider that fits through standard doorways
The Advance SC4000 28D is a mid-size ride-on floor scrubber for schools, hospitals, retail stores, arenas and other buildings with a mix of open floor and tight spaces. A 28 in disk deck scrubs while the rear squeegee picks up, and 33 gal solution and recovery tanks keep it working between fills. Nilfisk rates the standard model at up to 53,590 sq ft per hour.
The body is just 31.1 in wide, so it passes through standard-sized doorways, and the 65.5 in minimum aisle turn helps in narrow aisles. This is Nilfisk part number 56120023, the SC4000 28D package with batteries and a 36 V onboard charger.
Condition: Demo. Inspected by SES technicians.
