New Clarke FOCUS II 28 Disc Rider Scrubber
Our Take (from the SES Sales Team)
“The Focus II Rider 28 Disc is a full-size rider for facilities that scrub a lot of open floor, like school corridors, healthcare hallways, warehouses and big retail floors. With 31-gallon tanks, a 28-inch deck and up to 220 lb of scrub pressure, it can clean heavily soiled floors in one pass and keep going for a long time between dumps. The One-Touch controls are simple enough that new operators pick it up quickly. The 28-inch deck is the more maneuverable choice; if you have very wide open areas, look at the 34-inch model.
The real choice is batteries. The 310 Ah wet set with the onboard charger covers standard shifts. The 420 Ah wet set gives longer runs and charges from an off-board shelf charger, so plan a charging spot. The 312 Ah AGM set is sealed for crews that would rather not water batteries. Any package can come with the Chemical Mixing System if you want the machine to meter detergent.”

The Clarke Focus II Rider 28 Disc is a battery-powered ride-on floor scrubber with a 28 in (71 cm) disc deck and 31 gal (117 L) solution and recovery tanks. It is built for large hard-floor areas that need regular scrubbing, and three scrub pressure settings up to 220 lb (96 kg) let it clean heavily soiled floors in one pass. It cleans at up to 3.12 mph for a maximum coverage of 38,438 sq ft per hour, turns in a 63 in (160 cm) radius and runs at 68.6 dBA. Universal One-Touch™ controls keep operation simple, and the open design, angled floorboard and tools-free adjustable seat give the operator a clear line of sight and a comfortable ride.
