Abstract
A vacuum cleaner nozzle having a nozzle body (10) having a nozzle opening (13) facing a surface to be cleaned and one or more scraper blades. The scraper blades have a single, strip-shaped piece (16), made from rubber, plastic or some other elastic material. The blade has a first edge part (18) resting on the surface (19) to be cleaned and a second, opposite edge part which is secured in a holder (17) in the nozzle body. The distance (A) of the holder from the surface being cleaned is mainly constant when the scraper blade is moved forwards or rearwards on a hard surface. The length of the blade (16) extending toward the surface from the holder under free conditions is larger than the distance (A) from the holder to the surface so that the first edge part (18) during forward and rearward movement will trail behind the holder, as seen in the direction of movement of the nozzle. The blade (16) is shaped and constructed such that when the direction of movement of the nozzle is reversed, the blade serves as a soft spring for forces which are applied on the first edge part (18) from the surface (19) toward the holder (17).
