Clarke (Alto) FOCUS II RIDE 28B Parts and Support
Ride the green-cleaning wave Sustainable cleaning is on everyone’s shortlist. But is it possible without sacrificing performance? The Clarke® Focus® II Rider Autoscrubber proves it: Not only does it make green cleaning possible, but it can actually clean and restore floors more thoroughly and cost effectively at the same time. Your choice of a 28- or 34-inch disc deck or a 28-inch BOOST® Technology Deck can quickly clean or restore everything from school gymnasiums to healthcare hallways. And the 31-gallon tank paired with precision-controlled cleaning solution flow rates allow up to 155 minutes of scrubbing between refills. The Clarke Focus II Rider takes operator comfort and easy operation to new levels, as well. Its open design allows drivers to access the drivers’ compartment from the left or right, and then quickly modify the seat for optimum comfort. Other features move comfort even further, including the low-step height, anti-slip floor, recessed foot pedal and angled floorboard.
