  • the nozzle body remains in its usual suction or displacement direction, so that a Randabsaugung means of the swiveled nozzle head by the further oriented in the direction of displacement rollers of the nozzle body for the user means no additional effort. It is preferred in this case that the nozzle head automatically in a collision with an object, such as a baseboard or chair leg, pivoted relative to the nozzle body.

  • the nozzle head pivots automatically in the course of the forward movement of the vacuum cleaner in a pivoting position, which allows the retraction of the nozzle in the niche. It proves to be particularly advantageous in this case that even deep niches can be sucked off by the two-part design of the nozzle according to the invention. Also, this results in a comfortable and gentle sucking around furniture feet and obstacles, with always a comfortable and automatic adjustment to the surrounding situation while maintaining the usual way of working - only forward and backward movement, no sideways movement - is present.

  • a pivoting of the nozzle head affects neither its planar alignment nor an angle of attack of the vacuum cleaner to the nozzle, so that the user at a Pivoting the nozzle head no corrective measures are required.
  • the nozzle head in the pivoted state extends partially below the nozzle body. As a result, the nozzle head immersed in the pivoted state, at least with a partial area in a region covered by the nozzle body.

  • the nozzle head in the normal position has a greater width (ie extension transverse to the direction of travel) than depth (extension in the direction of travel).
  • a large width of the nozzle head is desired for the extraction of large areas. For evacuating niches, however, there should be a smaller width measured transversely to the direction of travel.
  • the width of the nozzle head is more than twice the greatest depth of the nozzle head.
  • a ratio of nozzle head width to nozzle head depth of 3: 1 may be provided.

  • the joint is formed in the region of the greatest depth of the nozzle head.
  • the nozzle head is pivotable relative to the nozzle body by 360 ° and more. Consequently, the nozzle head is preferably rotated arbitrarily, even to get back to its original normal position after a 360 ° rotation. It is further proposed that one or more preferred pivoting positions of the nozzle head are latched, including, for example, spring-assisted locking lugs, sliding or rolling body can occur in correspondingly formed recesses.

It proves to be advantageous in this case if the intended spring is held in the nozzle head and acts on the, the nozzle head passing through the suction channel of the nozzle body. It is further proposed that the spring passes through the suction channel. In this case, an orientation of the elongated spring element is preferred parallel to a front-side edge of the nozzle head, this at about the middle of enforcing the Saugkanalqueriteses.
  • the Saugkanalwandung is provided for this purpose with radially aligned openings for the flow rate of the spring or with correspondingly aligned grooves for receiving spring sections, so that a deflection of the nozzle head relative to the nozzle body causes a bending out on both sides of the Saugkanalwandung protruding and held in the nozzle head spring sections. This creates a restoring torque, which acts on the nozzle head in the direction of the normal position.
  • the training may also be selected so that the spring is connected to the suction channel, wherein more preferably in this case the spring does not pass through the suction channel. Rather, in this case a free end of the spring is held in the region of the Saugkanalwandung, so for example.

Alternatively, however, it can also be provided that the springs run in the basic position in the opposite direction. The construction of a uniform restoring torque in both a deflection in one direction and in the other direction is improved in that the springs are aligned symmetrically to each other. It is further proposed that the spring is designed as a leaf spring. As a spring material here spring steel, fiberglass and corresponding plastics may be provided. Furthermore, also by the geometry of the leaf spring width, thickness- a desired characteristic be designed the spring behavior.
  • the leaf spring has a curved cross section.

  • suction air flow is in this case influenced in such a way that the frictional force is lowered below the suction nozzle head, so that a deflection of the nozzle head for avoiding obstacles and the pivoting back takes place even when vacuuming carpets in the simplest way.
  • suction air flow is lower in a pivoting position than in a non-pivoted position.
  • a secondary air path is opened in a pivoting position. It is further preferred here that, when the nozzle head is pivoted through an angle of> 0 °, ie, out of the usual operating position of the nozzle head transversely to the direction of travel, a secondary air path is opened.
