Auto Scrubber Kent Razor Plus 24c 24 inch Gel Battery Plus family consists of 5 models designed on a modular platform to allow tools-free exchange of scrub decks. Three disc models (24D, 26D & 28D) are available featuring "click-off/click-on" scrub heads. The two cylindrical models (24C & 28C) have sweep/scrub multi-tasking capabilities. All models feature 21 gallons solution and recovery capacity, variable scrub pressure, the industry's best sound level, and a standard onboard battery charger. Additionally, the Economically Calibrated Orifice (ECO) System allows more than a full hour of productive scrubbing on a single refill/dump cycle. Options include additional scrub decks for multiple applications, maintenance-free gel batteries, and multiple scrub brushes. The cumulative result is a level of innovation, flexibility, safety, performance, productivity, reliability, and value not previously experienced in walkbehind automatic scrubbers.
