Conventionally, a suction cleaner nozzle comprises a coupling sleeve and a sole plate provided with a lower surface and at least one suction channel communicating with the coupling sleeve and opening onto the lower surface of the sole plate. The lower surface of the sole plate is intended to be located adjacent a surface to be cleaned during use of the cleaner nozzle.

In the case of such a suction cleaner nozzle, a portion of the waste sucked by the suction cleaner nozzle follows the path formed by the main suction channel and is discharged through a suction duct provided with the sole plate, while another portion of the waste sucked by the suction cleaner nozzle follows the auxiliary suction channel before being discharged also through the suction duct. The presence of the main suction channel and the auxiliary suction channel thus ensures an improved suction capacity of the suction cleaner nozzle, compared to a triangular shaped nozzle without an auxiliary suction channel.
