Pressing the “One Step Scrub Button” will lower the squeegee and scrub head
Only one actuator will be energized at any given time – squeegee is lowered
first, then the scrub head
Squeegee actuator uses internal limit switches to stop travel in upward and
downward travel
Scrub head actuator travel is controlled by monitoring actuator current in
upward travel and brush motor current in downward travel
Squeegee actuator can also be operated by pressing the “Vacuum Fan/
Squeegee Button”, without operating scrub brushes
