Abstract
An upright deep cleaner including a base housing pivotally connected to an upright handle, the upright handle carrying a liquid supply tank and the base housing including a recovery tank. The liquid supply tank includes an internal siphon tube for ensuring liquid flow to a feed valve when the upright handle is in the inclined position. The base housing includes a suction nozzle adjacent a spray bar, and removable floating brush for contacting a surface being cleaned, the brush being interchangeable with a bare floor tool including a sponge, brush, and squeegee. The recovery tank includes an internal baffle for preventing foaming of solution and a tank vent housing including a sponge-type filter to prevent spray from exiting the recovery tank. A vacuum motor cooling outlet is positioned on underside of the base housing to distribute air heated by the motor onto the surface to be cleaned.
