BRUMBY RIDE-ON SCRUBBER/DRYER
OPERATIONS MANUAL AND TROUBLESHOOTING GUIDE
Thank you for purchasing Mitchell Professional Floor Cleaning Equipment. Please
be sure to read the manual before operation.

Overview
The Mitchell BRUMBY GS-560D ride-on scrubber/dryer integrates both scrubbing and drying in
one machine, leaving the floor clean and dry in a single pass.
It is equipped with a quiet electric motor producing a low noise output of 58dB and capable of up
to a continuous 3-4 hours operation with a single charge.
The compact sized body is able to fit into most elevators for multi-storey transport and allows for
a smaller swing diameter capable of cleaning tight spaces efficiently.
How the machine works
Cleaning solution and water from the solution tank are released to the floor through a manually
controlled solution valve. The brush uses the detergent and water solution to scrub the floor
clean.
As the machine moves forward, the suction motor and squeegee wipes the dirty solution from
the floor and draws it into the recovery tank.
