Abstract
Abstract The combination of a vacuum cleaner and a dust filter container. The dust filter container does not have a conventional attachment plate. A support structure is located in the vacuum cleaner housing having a projecting member provided with a hole, the latter is inserted through a slot in the dust container whereby the hole aligns with an opening in the dust container. The hole in the projecting member and the opening form a through passage into the dust container from the inlet suction conduit of the vacuum cleaner. A seal is arranged in the vacuum cleaner housing between a flange on the suction conduit and a portion of the dust filter container surrounding the hole therein.
