Focus II Mid Size Autoscrubber

Debris is conveniently collected into a removable tray by the counter rotating brushes. The brushes are also easy to changeout without using tools.
Clarke Focus II CYL 28 CHEM, 312 Ah AGM batteries
The cylindrical brush deck paired with an onboard chemical dilution system. Two counter-rotating 28 inch brushes sweep debris into an onboard hopper while they scrub, so the machine picks up grit and small debris that a disc machine would push around, removing the need for a separate sweeping pass.
Why the CHEM option: the concentrate is metered into the solution line automatically at the correct ratio, so operators stop mixing by eye. That cuts chemical overuse and keeps results consistent between shifts.
This configuration: 312 Ah maintenance-free AGM batteries with onboard charger. This is the fully specified build of the CYL 28.
Cleaning path: 28 in cylindrical, 2 brushes
Solution tank: 23 gal
Batteries: 312 Ah AGM maintenance-free, included, with onboard charger
Dimensions: 59.5 x 31 x 44 in

- Easy access to the battery compartment is great for maintenance and installation and designed to contain any liquid spills. Choose either 242 or 310 Ah wet or 312 Ah maint-free (AGM) batteries.
- The optional Chemical Mixing System gauges the appropriate amount of chemical and mixes it into the solution flow. The ounce per gallon setting is controlled by a knob on the control panel.
- Quiet vacuum motor system - 65 decibels on disc, 63 decibels on the BOOST model. This allows the operator to use the scrubber in noise sensitive areas.
