Zusammenfassung:A nozzle (1) for cleaning devices comprising a housing (2) having a suction channel (7), a neck (3) connected to the suction channel, and a coupling unit (4) connected to the neck. The neck is shaped as a funnel having an opening (7b) connected to the suction channel, wherein the opening has a width at least 30% of the width of a second opening (7a) of the suction channel. The suction channel (7) may have a depth which decreases from the neck (3) towards the ends of the nozzle. This reduces the pressure loss and provides a higher flow velocity at the ends of the nozzle and a more uniform distribution of the flow velocity over the width of the nozzle.
