A vacuum waste removal system including a waste receiving container including a tank having an intake conduit, a dome carrying an air knife and having an outlet conduit and a filter screen removably located between an upper end of the tank and a lower end of the dome. The improvement is directed to a lift and lock arrangement interconnecting the dome with the tank. The arrangement includes a horizontal arm extending from one edge of the dome and tank to substantially the vertical axis of the container. A jack is connected with the first end of the arm while the second end connects with the dome and air knife. A conduit supplying air to the air knife passes through the connector connecting the dome with the end of the arm. The arrangement allows the dome, the conduit, and the air knife to be moved upward away from the tank a distance sufficient to allow removal and replacement of the filter. The arrangement then allows the dome, conduit and air knife to be cranked downwardly into sealed engagement with the tank. During these vertical movements, the dome is maintained aligned with the vertical axis of the cylinder.
