| 摘要 |
The invention concerns a vacuum cleaner nozzle comprising at least a flow channel (4a, 4b) substantially transverse to the forward moving direction of the nozzle (24), open towards the surface to be cleaned, and in ventilating connection with a suction channel (2). The invention is characterised in that at least a scraper blade (9b) in contact with the floor to be cleaned is arranged parallel to the channel (4A, 4B) and adjacent thereto. Furthermore, closure means (9a) of the channel (4A, 4B) produce an opening of the channel when the nozzle is moved in a direction wherein the scraper blade is upstream of the channel and a closure of the channel when the nozzle is moved in the opposite direction. |
