SQUEEGEE LIFT SYSTEM

TRACTION DRIVE

Although the squeegee lift is a manual lift there is an electrical circuit that the lift lever is
tied to. When the squeegee lever is moved it actuates a switch. This switch send a signal
to the controller telling it that the squeegee is down on the floor. When it sees this signal it
turns on the vacuum motor. When the squeegee lever is moved to lift the squeegee up, the
switch in no longer depressed and the signal going to the controller is interrupted. When
the controller no longer sees the signal for the vacuum motor it runs the vacuum motor for 21
additional seconds to clear any excess water from the squeegee hose and then it turns off
the vacuum motor.
