Abstract
The invention relates to a vacuum-cleaner nozzle for vacuuming an underlying surface, having a suction channel which opens out into a suction mouth. In order to form the vacuum-cleaner nozzle such that it has a relatively pronounced suction action for a sustained period of time, it is proposed according to the invention that the vacuum-cleaner nozzle comprises a lifting mechanism which interacts with the underlying surface and by means of which it is possible to change the distance of the suction mouth from the underlying surface on a periodic basis.
