Abstract

An endpiece for a vacuum cleaner comprising a plate (3) having a lower surface which rests on the ground and optionally fitted with elements such as brushes (8), optionally comprising channels which direct suctioned air to a suction opening (5), also having an upper surface (4) which is fitted with a tube (6) which communicates with said opening and which is connected to a suction unit located close to the tube or at a distance therefrom in the case of an installation having a centralized suctioning unit. The lower surface (7) of the plate (3) comprises at least three suction channels (9,10) between which a wiping device (12) is mounted, said two channels (9,10) being disposed to the front and to the rear of the wiping device (12) in the direction of displacement of said endpiece on the ground during vacuuming.

Claims

1. A vacuum-cleaner nozzle of the type comprising a foot (3), of which the underside, designed to come into contact with the floor, is optionally equipped with parts such as brushes (8) and optionally has channels directing the sucked air toward a suction orifice (5), and of which the upper surface (4) is equipped with a pipe (6) communicating with this orifice and connected to a vacuum-cleaning unit situated near the pipe or remote from it in the case of an installation having a centralized vacuum-cleaning unit, the underside (7) of the foot (3) having at least two suction channels (9, 10) between which a wiping device (12) is mounted, and the two channels (9, 10) being situated in front of and behind the wiping device (12), in the direction of movement of the nozzle over the floor during vacuum cleaning, which nozzle is characterized in that the wiping device (12) is a wipe or the like.

2. The nozzle as claimed in claim 1, characterized in that the wiping device (12) is mounted removably on the underside (7) of the foot (3).

3. The nozzle as claimed in either of claims 1 and 2, characterized in that when the underside of the foot (3) is fitted with brushes (8) defining in particular, at least in part, suction channels (9, 10), the lower plane of the wiping device (12) lies approximately in the lower plane of the brushes (8).

4. The nozzle as claimed in either of claims 2 and 3, characterized in that the wiping device (12) is fixed removably to the underside of the foot by hook and loop devices, such as those known under the trade mark Velcro.

5. The nozzle as claimed in one of claims 1 to 4, characterized in that the wiping device (12) has a device for wetting it from a reservoir of liquid.

6. The nozzle as claimed in one of claims 1 to 5, characterized in that it comprises means which, when the nozzle is moved in one direction, allow communication between the suction orifice (5) and the suction channel (9, 10) situated ahead of it in the direction of movement of the nozzle and closes the suction channel situated behind it.

7. The nozzle as claimed in claim 6, characterized in that the support (13) for the wiping device (12) is mounted on the foot (3) of the nozzle in such a way that it slides in the direction in which the nozzle is moved, so as to close the suction channel (10) situated behind it in the direction of movement of the nozzle (2) and uncover the suction channel (9) situated ahead of it.

8. The nozzle as claimed in one of claims 1 to 7, characterized in that the foot (3) is of generally rectangular shape and comprises two suction channels (9, 10) arranged along its two longitudinal edges.

9. The nozzle as claimed in one of claims 1 to 7, characterized in that the foot (3) is of generally ovoid shape and comprises two suction channels (9, 10) that meet at the two vertices.
