A vehicle mounted vacuum cleaning system (20) includes a portable frame (23), a cyclone separator (51) mounted to the frame and a blower (111) for urging in the airstream to pass through the cyclone separator. Movable support arms (53, 54) are provided for supporting the cyclone separator and for moving it between a first position adjacent the portable frame and a second position extended laterally from the portable frame. Lifting track (141) and rail (142) are provided for moving the cyclone separator between raised and lowered positions. The vacuum cleaning system further includes a plurality of filter bags (76) mounted within a filter bag house (75) and air purge grids (81 and 82) for cleaning all of the filter bags simultaneously. The air purge system includes a reservoir (93) for storing compressed air and valve means (96) for releasing a charge of compressed air into the filter bags in a direction generally opposite to the normal direction of airflow through the filter bags in response to the attainment of a selected pressure within the reservoir.
