Abstract
A wet cleaning suction nozzle having a suction opening (22) facing the floor and communicating with a nozzle outlet tube (12), scraper blades (24), one located in front of, and one behind, the suction opening as seen in the direction of movement of the nozzle, wherein the lower ends of the scraper blade abut the floor when the nozzle is used. The suction opening (22) is located closer to the floor than fastening points (23) of the scraper blades in the nozzle. The nozzle is used on hard, as well as soft floors, without being converted, and the nozzle includes spacers (31), which prevent the nozzle opening (22) from touching the floor when the nozzle is used on a hard floor, but which permits the suction opening to abut the floor when the nozzle is used on a soft floor.
