Abstract: A vacuum cleaner including a housing with a dust container therein and a suction opening with a detachable connection of a suction hose to the opening. The housing having an outer wall aligned with the suction opening and the suction opening in an inner wall. The connector body of the suction hose having tubular end piece with a connecting cone insertable into the suction opening through both walls of the housing and into the dust container.

Abstract: A cleaning appliance, in particular vacuum cleaner. The appliance comprises a filter and a heating device, by means of which the filter can be heated to carry out a pyrolytic cleaning process. During and/or after said pyrolytic cleaning process, at least neighbouring areas of the filter are cooled by a cooling air stream and the heating device is supplied with energy from a primary energy source. To prevent the risk of overheating and a potential fire if the primary energy source fails, the appliance is equipped with a secondary energy source, which can be used to generate the cooling air stream, at least if the primary energy source fails.

Abstract: A vacuum cleaner with a housing and a housing cover with a cable-pull opening in the housing cover. An electric cable has a plug on one end which can be pulled through a cut-out which is larger than the plug. During assembly the plug is pulled through the cut-out and then into a cable run area formed on one side of the cut-out and connected by a slit large enough for the cable but too small to accommodate the plug.

Abstract: A filter stop for a vacuum cleaner contains a dust chamber that is closable with a lid and receives a dust bag with a reinforcement plate in a specific fitting position. The filter stop has a base plate that is movable between two stopping positions parallel to the direction in which the reinforcement plate of the dust bag is inserted into the dust chamber. The filter stop is also provided with a swiveling lever that can be brought into a position activating the vacuuming function of the vacuum cleaner by the reinforcement plate when the dust bag is correctly positioned. The swiveling lever is in a position preventing the vacuuming function from being activated when the dust bag is not correctly positioned. The filter stop can be brought into a stop position activating the vacuuming function exclusively when the swiveling lever is actuated by a shoulder of the reinforcement plate.
