A float that is stuck will cause the vacuum motor to suck in water, resulting in vac motor damage. The recovery tank has a Recovery Tank Shutoff Float (10) to block the vacuum system when the recovery tank is full. You can tell when the float closes by the sudden change in the sound of the vacuum motor.
