  • Filter shaker assembly for sweeping machine
    Patent number: 8256061
    Abstract: A filter shaking assembly for a floor surface maintenance machine including a filter assembly in fluid communication with the debris hopper and having a cylindrical filter held against a shaker plate. The shaker plate is vibrated by a shaker motor at least partially positioned within an interior of the filter and eccentric mass to remove an accumulation of debris from the surface of the filter. The eccentric mass may include two eccentric masses positioned on a common shaft of the shaker motor.

  • Filter cleaning apparatus
    Patent number: 7896936
    Abstract: A filter cleaning mechanism for a cylindrical filter within a filter box of a surface maintenance machine having a shaker plate engaging a top end of the filter and having vibrations induced via a motor and eccentric mass combination. In one example, the motor and eccentric mass are mounted to a hinged cover plate via a vibration isolating connection. A pair of slot structures may limit movement of the filter to a generally vertical direction relative to ground.

  • Cyclonic filter for surface maintenance machine
    Patent number: 7662199
    Abstract: A filter system for a surface maintenance machine having a hopper assembly for receiving brush-thrown debris including a cyclonic separator for separating dust and debris from air drawn through the hopper via vacuum action. The cyclonic separator may include multiple cyclone and may be in fluid communication with the hopper assembly so as to periodically receive dust and debris exiting the filter system.
