Introducing the Clarke RA40™
Meet the RA40™: the most innovative Clarke scrubber ever.
This compact, highly maneuverable 20 inch 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 over the past 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 chemical, 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-TSteering, prevents tipping incidents. All these features contribute to
safer operation for both operators and other building occupants.
Steering Wheel Control Panel
Extremely user friendly and easy to learn
dashboard with One-Touch button and intuitive
display integrated into the steering wheel.
Exclusive multifunction digital display allows for
maximum customization of machine settings.
CMS Control Button
Clarke’s exclusive Chemical Mixing System
automatically mixes adjustable levels of
concentrated chemicals stored in an onboard
reservoir with clean water stored in the solution
tank. That means you can stop wasting unused
chemical, get more consistently clean floors and
give the RA40 an extra boost of cleaning power
for heavily soiled areas.
Onboard Squeegee Storage
Built-in squeegee hanging system on tank
allows for safe transportation through
doorways and tight areas, while
permitting tank drying.
