1. A vacuum cleaner nozzle comprising a nozzle body (10) and a scraper blade, said nozzle body having a nozzle opening (13) facing a surface to be cleaned, said scraper blade comprising a single, strip-shaped piece (16), made from an elastic material and having a first edge part (18) resting on said surface (19) and a second opposite edge part which is received in a holder (17) in the nozzle body, said nozzle body being maintained a generally constant distance (A) from the surface when the scraper blade is moved forwards or rearwards on a hard surface, the length of the piece (16) extending toward the surface from the holder under free conditions being larger than said generally constant distance (A) so that the first edge part (18) during said movement trails behind the holder as seen in the direction of movement of the nozzle, wherein the piece (16) serves as a soft spring when the direction of movement of the nozzle is reversed, and thereby dampens forces which are applied on the first edge part (18) toward the holder (17).
