ABSTRACT:
A sweeper hopper with a filter assembly is provided. The filter assembly separates the hopper into a dirt and debris-receiving chamber and an exhaust chamber. Air-borne dirt carried through the dirt and debris chamber is trapped by the filter assembly and the air enters the exhaust chamber from which it is exhausted through a blower. A holding frame holds the filter in place against a supporting frame or flanges. The frame has a shaker motor which is periodically operated to clean the filter by vibration. When the filter is to be replaced, the holding frame is readily separable therefrom for rapid replacement, yet the holding frame securely holds the filter in place when the sweeper is in operation.
