  • Page 35: Recovery System

    RECOVERY SYSTEM FUNCTIONAL OVERVIEW Vacuum / Recovery System General Dirt and water are lifted off the floor into the recovery tank by airflow, created by a 3-Stage 36V vacuum motor. The wastewater and air enter the vacuum system at the squeegee tool, through small openings (notches) located in the front squeegee blade. The small openings are the entrance points for the water and air, and help speed up the airflow producing the suction to lift the wastewater off of the floor.
