Abstract (en)
[origin: WO2009128763A1] This invention relates to a vacuum cleaner nozzle comprising a suction plate (10) having an inlet side (11) and an outlet side (12). The suction plate comprises an air duct (30) having a duct wall (31). The air duct extends through the suction plate from a suction opening (13) on the inlet side to the outlet side. A first primary sealing edge (19) for engaging with a surface bein cleaned and for at least partly sealing the suction opening 13 against the surface being cleaned extends along at least a portion of a side (15) of the suction opening. The invention is characterized by that at least one inlet end portion of the duct wall forms an elongated first protrusion (32), which provides a first secondary sealing edge. The first secondary sealing edge extends along at least a portion of the first primary sealing edge and is horizontally displaced from the first primary sealing edge. The secondary sealing edge is provided in order to yield better dust removal ability from carpets as well as providing a more comfortable cleaning experience
