ABSTRACT:
A vacuum cleaner having a body with an inlet opening for dust laden air and an outlet. An impeller is located between the inlet and the outlet. A chamber within the body having at least one wall receives a perforate dust receptacle. The chamber is located up-stream of the impeller. An inlet passageway extends from the inlet opening into the chamber. This passageway is directed so that when a perforate dust receptacle is in position in the chamber, the inlet passage has an outlet directed at a wall of the dust receptacle. Dust laden air entering the receptacle is filtered to remove dust. The dust laden air, forced against the wall by the impeller, acts to keep the wall free of dust accumulation.
