Zusammenfassung:	An external filter box for a surface maintenance machine having a hopper with selective communication being provided between the filter box and the hopper to permit dusty air to flow from the hopper to the filter box and to permit dust and debris captured by the filter box to flow into the hopper. In one example, the hopper includes a prefilter assembly which is coupled to an inlet of the filter box during a sweeping operation and which is removed away from the filter box during a hopper dump procedure.
