The present invention relates to a vacuum cleaner nozzle (10; 10') adapted to contact a working surface, said vacuun cleaner nozzle including a brush nozzle (12; 12') having edge portions (16b, 16c; 16'b, 16'c) provided along the longitudinal sides of the brush nozzle (12; 12'). The invention also relates to a method to perform edge cleaning along the front edge portion, seen in the direction of motion, of the brush nozzle (12; 12'). Known vacuum cleaner nozzles have the disadvantage that when the brush nozzle is active dust and solid particles are transported around on the working surface that is vacuumed, i.e. dust and solid particles will not enter inside the brush rim. Further, known brush nozzles do not have edge cleaning along the front edge, seen in the direction of motion. Significant for the present invention is that the longitudinal edge portions (16b, 16c; 16'b, 16'c) are given a synchronized elevating/lowering movement whereby a front edge portion (16b; 16'b), seen in the direction of motion, is elevated from the working surface while simultaneously a rear edge portion (16c; 16'c), seen in the direction of motion, is lowered against the working surface.
