  • Patent number: 8418311
    Abstract: A vacuum cleaner having a vacuum cleaner body, a suction fan and motor operatively associated with the vacuum cleaner body, and a wheel. The wheel has a wheel body having an axis of rotation, a tread surface, and a cushion layer radially interposed between the wheel body and the tread surface. The cushion layer includes a resilient shell having a plurality of resilient cells therein. The shell and the plurality of cells have one or more gasses in them, and are dimensioned to damp vibrations and impacts between the tread surface and a floor surface that the tread surface contacts as the wheel rotates about the axis of rotation.

  • Publication number: 20100306955
    Abstract: A vacuum cleaner dust separation unit having a cyclone chamber (113) and a dust collection chamber (115). The cyclone chamber (113) extends along a longitudinal axis (398), and has an air inlet (183), an air outlet (408), an inlet wall (396) between the air inlet (183) and the air outlet (408), and one or more air passages (404) through the inlet wall (396). The dust collection chamber (115) is adapted to receive dirt from the cyclone chamber (113). In one aspect, the inlet wall (396) comprises an elliptical wall that is located adjacent the air inlet (182) and angled relative to the longitudinal axis (398). In another aspect, the cyclone chamber (113) has an end wall (432) located opposite the inlet wall (396), and a dirt outlet (114) to the dust collection chamber (115) located adjacent the end wall (432), and the end wall (432) has a recessed portion (438) surrounding an extended portion (436) that protrudes into the cyclone chamber (113).

  • Publication number: 20100306960
    Abstract: This invention relates to a telescopic vacuum cleaner tube comprising a first inner tube, a second inner tube, and an outer tube, wherein the first and second inner tubes are arranged to form first and second telescopic links relative to first and second end portions of the outer tube, respectively. The outer tube forms the intermediate tube of the three-part tube while at the same time being fully accessible in any position, whereby one common grip for operating both of the two respective telescopic links, formed by the first and second inner tubes and the intermediate outer tube, of the three part telescopic tube is obtained.
