  • the front strip consists for example of a bristle strip, which can be profiled at its lower edge.
  • a suction nozzle with the described features is for example off DE 29812 377 U1 known. It is suitable for large-scale removal of dust on smooth floors or textile floor coverings. Decisive for the success and the quality of the suction process is that the suction mouth on the underside of the suction nozzle is guided as close as possible above the floor surface. The Movement of the suction air thereby achieves the high speed required to remove the dust particles.
  • the nozzle has a manually operable mechanical device for lowering a arranged in the suction head carrier to which a front-mounted bristle strip and a rear-side sealing element are attached. With this arrangement, dust, fibers, lint and the like can be effectively absorbed.
  • a suction nozzle for sucking hard floors which has at the bottom of the suction head protruding bristle strips.
  • the bristle strips limit the suction space at the back of the suction opening.
  • a separate front strip is provided, which is vertically adjustable. By lifting the front strip, the ground clearance in front of the suction opening for sucking coarse particles can be increased.
  • a drive is provided, which is controlled by a dirt sensor.
  • the invention has for its object to provide a universally applicable to textile floor coverings and smooth floors suction nozzle, which has both good suction properties for dust and for coarse dirt particles and is easy to use.
  • the suction nozzle has a separately switchable additional device for vacuuming coarse dirt, with which the front strip already extended between the floor surface to be cleaned and the floor smoothed for suction while maintaining the pivoting mobility of the suction head, a ground clearance of more than 2 mm is adjustable and / or the Flow cross-section of openings in the front strip is changeable. This will get you Suction movements and coarse dirt particles that lie on the floor surface in front of the front of the suction head, under the suction mouth, are detected there by the air flow and removed via the suction channel. There are several possibilities for the further structural design of the additional device.
  • the additional device has at least one displaceable or pivotally mounted in the suction head additional front-sealing element, through the actuation of openings in the front strip can be closed.
  • the openings of the front strip are closed to collect dust on slightly soiled smooth floors. For Grobschmutzing the openings that extend to the lower edge of the front strip, released by an actuation of the front sealing element.
  • a further embodiment of the additional device provides that the suction head in the region of the sole has support rollers which are vertically adjustable with the additional device.
  • the support rollers of the suction head can be raised to a higher level, so that between the extended front strip and the bottom surface a ground clearance of more than 2 mm, advantageously a distance between 3 mm and 10 mm and preferably a distance between 5 mm and 10 mm established.
  • the support rollers are preferably arranged in the front region of the sliding sole, in particular in the vicinity of the front strip, so that the sliding sole can be tilted relative to the ground by extending these support rollers.
  • sealing elements on the narrow sides and / or the back of the suction head to avoid a lateral and / or back air flow on the underside of the suction head and are extended.
  • the sealing elements ensure that when lifting or tilting the suction head relative to the floor, the air flow at the front of the Suction head enters the suction mouth and be taken on a forward movement of the suction head coarse dirt particles effectively. A reduction of the air flow rate by lateral or backside false air is thus avoided.
  • the lifting or tilting in combination with a lateral and rear sealing of the suction head has the further advantage that the rear seal eg by means of a flexible sealing lip during forward movement of the suction head any dirt that has not been fully absorbed, collects what the sucking relieved in the next forward stroke.
  • the suction head of the auxiliary device is associated with a switchable electric drive to the elements of the attachment, e.g. Support rollers and / or a front sealing element to adjust.
  • the electric drive can be controlled by a sensor module that detects coarse dirt on the floor surface. Due to the sensor-controlled motorized operation of the attachment, the adjustment according to the invention of the ground clearance or the inventive opening and closing of openings of the front strip is carried out automatically.
  • the sensor of the sensor module can be used as a non-contact sensor, e.g. be designed as an optical sensor, laser optical sensor or ultrasonic sensor.
  • the sensor may be formed as a touch sensor, for example as a piezo-mechanical sensor or capacitive touch sensor. Such touch sensors already respond to weak touches as they are caused by coarse dirt particles on, for example, smooth floors, and control according to the motor drive of the attachment.
  • the electrically operated auxiliary device is operated periodically.
  • the function according to the invention for coarse dirt removal is regularly recurring Given timing cycles, so that in terms of time, both the coarse dirt removal and the fine dirt removal is effective in the same way.
