Abstract
A wet/dry vacuum apparatus is disclosed including a collection tank and a suction head. The suction head includes a base defining a tank inlet aperture, a blower intake aperture, a blower exhaust aperture, an atmospheric, intake-discharge aperture and an integrally molded valve housing. A blower is secured to the base in line with the intake aperture and includes an exhaust outlet connected to the exhaust aperture. The valve housing is opposite the blower and defines a tank opening communicating with the collection tank. A planar valve element is rotatably mounted within the housing and selectively permits communication of the blower intake with the tank for collection of debris and liquid or connection of the blower exhaust outlet with the tank to pressurize the tank and force the contents thereof out through the tank inlet.
