Abstract
A vacuum cleaner includes a receiving chamber and a removable dust collecting container. The dust collecting container has a guide groove on that outer surface facing the inlet flow connection of the vacuum cleaner, and this guide groove is adapted or matched to the discharge opening of the inlet flow connection. The guide groove extends from the bottom surface of the dust collecting container vertically upwardly as far as to the inlet flow opening of the dust collecting container. The dust collecting container has short inlet ribs arranged in an upper region upon that outer surface located across from the inlet flow opening and starting ribs in the transition between the bottom surface of the receiving chamber inlet rib containing wall. A soft elastic seal is pressed against the sealing surface of the dust collecting container in a region of the inlet flow opening, and the sealing surface surrounds the inlet flow connection.
