| 摘要 |
The invention concerns a floor nozzle (1) for vacuum cleaner, comprising a suction chamber delimited at the front and at the rear, in the advancing direction (r) by delimiting elements (5, 5') for example, runners, a rotary brush (6) being optionally mounted inside the suction chamber (2). The invention aims at improving a vacuum cleaner nozzle of this type, particularly in terms of maneuverability for carpet vacuum cleaning. Therefor, the delimiting elements (5') are designed to be vertically mobile, over a partial zone and said delimiting elements (5') can be automatically lifted, depending on the substrate present in the suction chamber (2) and/or depending on a forward (r) or backward (r') movement of the floor nozzle (1). |
