ABSTRACT:
A vacuum cleaner has an electric motor driving an air impeller for creating suction and a pump which draws liquid material through an inlet tube from the bottom of a tank and expels it from the tank. A priming mechanism is disposed in fluid communication with the outlet portion of the pump. The priming mechanism primes the pump from the outlet side of the pump by collecting liquid received by the tank of the vacuum cleaner in the priming mechanism and establishing a pressure differential across this collected liquid.
