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 the tank and expels it from the tank. A priming apparatus is disposed in the tank chamber in fluid communication with the pump and a valve is selectively actuable to establish a pressure differential across liquid in the priming apparatus to thereby prime the pump.
