Clarke RA40

Clarke RA40 20D Micro Ride-on Scrubber

This compact, highly maneuverable 20'' ride-on autoscrubber 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. SmartFlow technology automatically reduces the solution flow rate when the operator slows down, such as on turns, edge cleaning and maneuvering around obstacles, avoiding left behind water. This improves tank and operator productivity by up to 50%, reduces chemical usage and costs, and helps eliminate expensive slip and fall injuries. The RA40’s chemical mixing system allows you to vary the chemical concentration as needed to clean light to heavily soiled areas, and the machine provides two levels of scrubbing pressure. Its small profile design provides full sightline visibility, a short turning radius and the ability to clean in tight spaces. Clean up to 32,560 feet per hour at 3.7 mph.
