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.
