UNDERWATER CLEANER
The invention relates to an underwater cleaner (1), in particular for a swimming pool, comprising a suction nozzle housing (3) having a suction nozzle (2) which communicates with a suction chamber (4), and having a suction mouth (10) which defines a suction plane (9), wherein an outlet channel (5) stems from the suction chamber (4), which outlet channel has a connection (6) for a filter device in the region of its outlet opening (50), and comprising at least one water jet nozzle (7, 12) which opens into the suction chamber (4) in the region of the suction nozzle (2) and via which water can be fed under pressure into the suction chamber (4) such that a negative pressure is established in the suction chamber (4) according to the water jet pump principle, wherein a first water jet nozzle (7) opens into the suction chamber (4) in such a way that a flow center line (7a) of the first water jet nozzle (7) is directed into the outlet channel (5), wherein the first water jet nozzle (7) is formed in one piece with the suction nozzle housing (3) and the suction nozzle housing (3) can be produced together with the first water jet nozzle (7) by injection molding.To enable easy production, it is provided that the first water jet nozzle (7) can be formed by a slider that can be pulled through the outlet channel (5) from the side (A) of the connection (6) for the filter device, and that the first water jet nozzle (7) widens in the direction of flow of the water jet.
