Product Details

The greatest feature of this Clarke Focus II automatic ride on floor scrubber is the ability for you to customize it to your needs! It can be purchased with a 28" or 34" rotary (disc) deck for use in large areas to do normal cleaning. It can also be purchase with a 14" x 28" oscillating deck with BOOST technology for chemical-free stripping and low-chemical floor scrubbing.

All different machine variations come with pad drivers, so the 28" rotary machine uses 14" pads, the 34" rotary machine option uses 17" pads, and the BOOST machine uses 14" x 28" pads. Other brush options are available for uneven floors like unfinished concrete or grouted tile.

We've found that this Focus II rider scrubber excels in wide open areas like those found in manufacturing facilities, warehouses, gymnasiums and cafeterias. A large 31 gallon tank and low-solution flow rates result in 84 minutes of continuous scrubbing without having to dump your recovered water or refill your clean solution tank. Variable down pressure settings allow you dial the exact amount of pressure you need for each cleaning job (regular, heavy & extreme scrub). A follow behind squeegee system leaves the floor dry to the touch after scrubbing.
