This compact, highly maneuverable 20 inch auto scrubber is designed to elevate the cleanliness, health and safety of your facility to the next level. Every cutting-edge feature-from the ultra-sharp turning radius to the onboard chemical mixing system- has been engineered to the high performance and reliability standards you have come to expect from Clarke over 100 years!
SmartFlow technology increases productivity.
SmartFlow technology automatically reduces the solution flow rate when the operator slows down. Automatically reducing the flow rate on turns, edge cleaning or maneuvering around obstacles helps to avoid water left behind and increases the productivity by up to 50% per tank. This means greatly reduced slip and fall risk and cost to clean. Reducing the amount of cleaning solution used also prevents wasting water and chemicals, increasing sustainability.
Extreme maneuverability and safer control.
The small profile design of the RA40 provides full sightline visibility, a short turning radius and the ability to clean in tight spaces. It also contributes to a low center of gravity that, when combined with Safe-T-Steering, prevents tipping incidents. All these features contribute to safer operation for both operators and other building occupants.
-Large, 18.5 gallon tank for high cleaning productivity
-Two levels of scrub pressure for added cleaning power in heavily soiled areas
-Water-level indicator easily viewable from the operator’s seat
-Easy-removal squeegee with built in squeegee hanger stores easily on the backside when not in use
-Scrub deck and squeegee raise and lower quickly and easily
-Lid lifts off easily, providing access to clean tank and debris catcher
-Low step-on design makes for easy onboarding and offboarding
-Wide, ergonomic operator seat and steering wheel provide a more comfortable driving experience
