Stand-up to increased performance
and productivity
A cost-efficient cleaning solution
Clarke has been helping cleaning professionals increase cleaning effectiveness and
productivity for 100 years. Now we are pleased to introduce the SA40 stand on
scrubber to further enhance your cleaning productivity. Designed to deliver reliable
cleaning performance, the SA40 stand-on scrubber provides a flexible, extremely
maneuverable and compact solution for small to medium-sized areas.
Maximum productivity
Clarke has set the standard for robust, productive, easy to use and reliable cleaning
equipment. The Clarke SA40 is designed with a large 12 gallon solution tank and low
flow rate, which can provide up to 75 minutes of scrub time without refilling, so you
will spend more time cleaning. The SA40 is also engineered to provide increased down
pressure at 75 pounds to enable you to enjoy maximum clean in a single pass.
Consistent, easy cleaning
The SA40 ensures consistent, reliable cleaning with solution flow rate control right at
your fingertips. Select from low, medium or high flow rates to match the job at hand
without stopping the machine. This not only minimizes cleaning solution waste but also
reduces time spent on dump and refills. For simple operation, all scrubbing parameters—
brush pressure, solution flow and vacuum—are controlled with individual buttons, and
are clearly displayed on the easy-to-read, LCD graphical display.
True Blue sustainability
With the SA40 you can enjoy a high level of cleaning performance without sacrificing
sustainability. The SA40 is designed to allow you to clean with minimal consumption of
detergent and water so that real savings can be gained without compromising
performance or the environment. All Clarke auto scrubbers feature important benefits
such as low noise levels, enhanced user ergonomics, onboard chargers and superior
pickup to ensure you are left with clean, dry and safe floors.
