A suction sweeping machine includes a filter arrangement for collecting debris from a fluid stream. The filter arrangement comprises an outlet leading into the filter arrangement, a container, preferably in the form of a plastic bag, for collecting debris and having an open upper end, and a porous tube which extends downwardly into the bag. The arrangement is such that a debris carrying fluid stream flowing from the outlet diffuses through the porous tube and out of the open end of the bag, while the debris remains within the bag. Preferably, the porous tube is flexible. In a preferred construction, the plastic bag is located in a compartment with an access door in a sidewall thereof, and a plurality of candle filters provide a secondary filter.
