Walk-Behind Floor Scrubbers
Whether you need a conventional disc-powered scrub deck, a cylindrical model for rough or textured floors, or the green-cleaning sustainability of BOOST® Technology, there’s a rugged, reliable Clarke® Focus® II Mid-Size Scrubber that can improve your floor cleaning efficiency.
Clarke Focus II BOOST 28 CHEM, 312 Ah AGM batteries
Clarke's orbital BOOST deck paired with an onboard chemical dilution system. The deck oscillates rather than rotating, so it can strip finish using water alone, and the CHEM system meters detergent into the solution line at the correct ratio for the jobs where you do want chemical.
Why the CHEM option: operators stop mixing by eye. The concentrate is dosed automatically, which cuts overuse, keeps results consistent between shifts, and lets one machine switch between chemical-free stripping and dosed scrubbing without a tank change.
This configuration: 312 Ah maintenance-free AGM batteries with onboard charger. This is the longest-running and most hands-off build in the BOOST 28 family.

Solution tank: 23 gal
Batteries: 312 Ah AGM maintenance-free, included, with onboard charger
