According to the invention, the hinge axis of the tilting joint is arranged within the indentation in a region near the bottom of the suction head. This results in a particularly favorable introduction of force of the pushing force.
  • In the first functional position, the broad side of the suction head is aligned substantially transversely to a suction pipe connected to the connecting end of the pipe bend. In a forward movement of the floor nozzle, a pushing force is introduced into the suction head, wherein the force line of action of the pushing force is displaced in the suction direction in the rear region of the floor nozzle. At the front in the suction direction broadside of the suction head can perform smooth tilting movements, so that carpet folds and carpet edges can be run over well. Consequently, the floor nozzle according to the invention is characterized by good sliding properties on floor surfaces. Furthermore, the device is easy to handle both when vacuuming wide floor surfaces and narrow niches.
  • The pivoting range of the movable channel portion is limited by stops, wherein a stop is assigned to the second functional position appropriate.
  • In a further embodiment, the invention teaches that the suction head has an upper housing part and an insert connected to the upper housing part and that the channel connecting piece of the tilting joint consists of two parts, wherein the one part is integrally formed on the upper housing part and the other part of the insert. The suction head is a plastic part. The two-part design of the suction head leads to simplifications of the injection molds. Suitably, the outer surface of the channel connecting piece is integrally formed on the upper housing part and the insert has a shaped piece, which forms a portion of the adapted to the geometry of the movable channel section inner contour.
  • On the underside of the suction head, a sliding sole can be arranged in a manner known per se, which has a suction mouth extending up to the narrow sides, which is connected in terms of flow through an opening to the channel connecting piece.
