Patent number: 7475451Abstract: 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.Type: GrantFiled: October 28, 2004Date of Patent: January 13, 2009Assignee: BISSELL Homecare, Inc.Inventors: Kenneth M.

Patent number: 6158081Abstract: The invention relates to a water extraction cleaning machine having a variable solution mixing valve adapted to create cleaning solution mixtures of variable constituent ratios. Clean water and detergent are provided from tanks supported on the water extraction cleaning machines. The size of the detergent inlet opening can be altered through rotation of a control knob provided on the outside of the water extraction cleaning machine. The knob is interconnected to at least one member which is adapted to vary the size of one of the detergent fluid inlet and the clean water inlet so that the ratio of constituent elements can be altered depending upon the cleaning application.Type: GrantFiled: August 25, 1998Date of Patent: December 12, 2000Assignee: Bissell Homecare, Inc.Inventors: Timothy E.
