Squeegee System
Functional Description
Overview
The squeegee system includes the squeegee assembly, squeegee mounting assembly, squeegee lift weldment
and the squeegee lift cylinder.
The squeegee assembly is mounted at the bottom rear of the machine and picks up the water from the floor.
Two squeegee blades (front and rear) pick up the water and direct it into the vacuum hose which carries it to
the recovery tank. The squeegee lift cylinder raises and lowers the squeegee as appropriate for the operation
being performed.
