Abstract
A system includes a vacuum cleaner with a dust chamber having ribs and a dust bag including a fleece disposed on a supporting structure. The fleece includes a plurality of fleece corrugations, with a distance between the fleece corrugations being matched to a distance between the dust chamber ribs. The resultant matching of the fleece corrugation spacing and the spacing of the dust chamber rib prevents partial or large-area contact of portions of the dust bag with an inner surface of the dust chamber.
