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.
