  • Patent number: 7418764
    Abstract: An upright vacuum cleaner is provided having a suction nozzle height adjustment arrangement controlled by a rotary mode control member located on the upper housing. The rotary mode control member controls a suction nozzle height adjustment motor and a rotary agitator drive disconnect arrangement. A wheel tensioner located on an idler arm is operatively connected to a cam on the suction nozzle height adjustment motor which tensions and de-tensions the agitator drive belt to control the rotary agitator. The rotary mode control member could have discrete settings for the various floor surfaces to be cleaned including bare floors and carpet of varying pile heights. Alternately, the rotary mode control member could be variable so that an infinite number of suction nozzle height settings can be selected.

  • Patent number: 7340797
    Abstract: The cleaning apparatus includes a base portion for movement along the surface and a handle pivotally connected to the base portion. A recovery tank is removably mounted to the handle and has a front end. A lid covers the recovery tank and has an inlet opening for directing dirt and liquid into the recovery tank and an outlet opening located at the front end of the recovery tank. A suction nozzle is secured to the base portion and fluidly communicates with the inlet opening of the lid. A suction source fluidly communicates with the outlet opening for drawing dirt and liquid from the surface through the suction nozzle and into the recovery tank. A partition device is positioned between the outlet opening and the inlet opening and extends down within the recovery tank a sufficient distance to prevent the liquid from flowing from the inlet opening to the outlet opening.

  • Patent number: 7332005
    Abstract: A floor care appliance such as a vacuum cleaner is provided having an filtration bag changing assembly located in the filtration compartment. A supply of filtration material is packaged in a container in the form of a continuous tube to be fed into the filtration compartment. A sealing and cutting assembly seals the tube at the lower end after a bag is fed into the filtration compartment. Once a filtration bag is full, a new filtration bag is pulled into place with the lower end of the tube being sealed and the old filtration bag being cut from the tube by a cutter. A pair of opposing heating elements are used to seal the opposing sidewalls of the tube together to form the filtration bag. The free end of the tube is fluidly connected to the suction nozzle by a connector and a dirt duct.

  • Patent number: 7316051
    Abstract: A floor care appliance is provided with a switch for controlling the height of the suction nozzle. The switch controls the height of the suction nozzle by controlling the operation of an independent motor and a gear and cam arrangement operatively connected to the wheel carriage. Another cam arrangement is operatively connected to the independent motor which engages suction nozzle height adjustment travel limits at both extremes of the suction nozzle height. The suction nozzle height adjustment travel limit switches turn off current to the independent motor at the extremes of the suction nozzle height to prevent overheating of the independent motor and over travel. In the preferred embodiment of the invention, two wires connect the suction nozzle height control switch to the independent motor along with the two travel limit switches and a pair of diodes.
