Abstract:
An electric window cleaning device includes an operating portion and a wiping portion which are attracted to both sides of a glass of a window by magnets, and are free to move along the glass by virtue of balls. The wiping portion includes a power mechanism and a power supply device. The power mechanism includes an output shaft, a rotary disc and a duster removably fixed to the rotary disc. The power device includes a switch and a battery which are electrically connected to the power mechanism. When the power mechanism is turned on, the output shaft rotates the rotary disc and the duster to clean the outer surface of the glass, as an user moves the operating portion which is attracted to the inner surface of the glass, the wiping portion will also move along the outer surface of the glass to perform cleaning operation.

Abstract:
A carpet extractor valve assembly (340,522) alternately directs cleaning solution to a base-mounted spray bar (74,526) or to a remote distributor (438,614) of an accessory tool (16,524). The valve assembly includes an inlet port (344), which receives cleaning fluid from a handle-mounted reservoir (14,574), and first and second discharge ports (400, 442), connected to the spray bar and the accessory tool, respectively. First and second valve members (352,354) include first and second poppets (362, 444), which are biased by a spring (384) to normally-closed positions in which the first and second discharge ports are sealed. A trigger-operated actuation rod (410) actuates the first valve member to release cleaning fluid to the spray bar. A quick connect coupling (464,466,608,610) connects the remote distributor with the second discharge port and opens the second valve member thereby. In one embodiment, a cleaning solution pump (480), mounted in a pump housing (490) over a base assembly A, is coupled between the valve assembly (340) and the remote distributor (438). In another embodiment, a pump (520) is connected between a cleaning solution tank (574) and the valve assembly inlet port and pressurizes cleaning fluid for both the spray bar (526) and the remote distributor (614).
