Recovery System

Functional Description
Overview
The recovery system picks up the scrubbing solution from the floor and directs it into the recovery tank.
The squeegee vacuum fan, driven by a hydraulic motor powered by the auxiliary pump, draws air from
the recovery tank to create a vacuum in the tank and at the squeegee to pick up the solution. The solution
travels through the squeegee hose and into the recovery tank.
The Squeegee Blade Switch on the instrument panel switches the squeegee vacuum fan motor on and off as
well as extending and retracting the squeegee.
