US 10,368,710 B1 · Ergonomic multi-functional cleaning machine

Abstract

In one aspect, the invention is directed to a cleaning machine that includes a fresh liquid tank, a vacuum tank, and an electromechanical assembly—with the electromechanical assembly including an electromechanical housing, a pump, and a vacuum motor. In this particular aspect of the invention, the pump and the vacuum motor are mounted to the electromechanical housing; and the electromechanical assembly is releasably connected to the fresh liquid tank. In another aspect, the invention is directed to a method for rapid replacement of the electromechanical components of the cleaning machine described immediately above. The method includes disconnecting the electromechanical assembly from the fresh liquid tank, and connecting a replacement electromechanical assembly to the fresh liquid tank. The replacement electromechanical assembly includes a replacement electromechanical housing, a replacement pump, and a replacement vacuum motor, with the replacement pump and replacement vacuum motor being mounted to the replacement electromechanical housing. In a further aspect, the invention is directed to a cleaning machine that includes a vacuum tank comprising a suction inlet, a vacuum motor operable to vacuum a soil-containing liquid into the vacuum tank through the suction inlet, and a HEPA filtration assembly constructed and arranged to receive a HEPA filter. In this fashion, air drawn into the vacuum tank through the suction inlet may undergo high efficiency filtration before exiting the cleaning machine.
