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.
