Squeegee System
Functional Description
Overview
The squeegee assembly is mounted at the bottom rear of the machine and picks up the water from the oor.
Two squeegee blades (front and rear) pick up the water and direct it into the squeegee support assembly.
A vacuum hose attached to the support assembly lifts the water from the squeegee and directs it to the
recovery tank. The squeegee lift actuator raises and lowers the squeegee as appropriate for the operation
being performed. The squeegee mounting system is designed to allow the squeegee blades enough side-to-
side movement to conform to the oor surface and swing sideways when turning.
