Title: Self-evacuating vacuum cleaner
Inventor: BERFIELD ROBERT C
IPC: A47L9/00
Filed: 1997-07-11
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. The vacuum cleaner also includes a mechanical shut-off and override assembly that automatically shuts off the motor if the liquid level in the tank gets too high. A user, however, can mechanically override this automatic shut-off in order to continue pumping liquid out of the tank. A priming apparatus is disposed in the tank 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.
