New Clarke FOCUS II Disc 28 Midsize Floor Scrubber
Our Take (from the SES Sales Team)
“The FOCUS II midsize is the walk-behind for buildings that have outgrown a 20-inch machine but don't have the room or the budget for a rider. Two 14-inch pad drivers give you a 28-inch path, and the 23-gallon tanks mean an operator can work a long hallway or a big retail floor without stopping to dump and refill.
The body is rotomolded Polydur®, which shrugs off the bumps and dings walk-behinds take in daily use. The four configurations come down to two questions: do you want sealed AGM batteries or lower-cost wet batteries, and do you want the chemical mixing system so detergent is metered automatically instead of premixed in the tank?”

A 28-inch walk-behind that works like a small rider
The Clarke FOCUS® II Disc 28 Mid Size Autoscrubber® is built for schools, healthcare, retail, grocery, hospitality and cleaning contractors who scrub large open floors every day.

Four ways to build it
All four include two 14-inch pad holders, a 24 V onboard charger and the same 23-gallon tanks. Find your row and column:
| Batteries | Standard | With chemical mixing system |
|---|---|---|
| 242 Ah wet Lower cost; needs watering | Model 05401A | Model 05405A |

What the chemical mixing system does
Features:
- Patented pulse-modulated solution control for precise, consistent solution delivery
- Gimbal-mounted pad drivers ride over uneven floors for even scrubbing
- Yellow palm buttons and a one-touch control panel that almost any operator can learn
- Rear solution fill and an electronic float that shuts off the vacuum when the recovery tank is full
- Tool-free squeegee adjustment with chemical-resistant urethane blades
