The invention relates to a device and a method for cleaning pipes and channels by means of pressurized water and rotatable tools (11), comprising a connection part (2) for a pressurized water line, which connection part comprises a pivot bearing (5a) and is provided with a tool head (6), which can be rotated relative to the pivot bearing (5a) and can be set in rotation by rotary nozzles. In order to achieve the aim of not destroying any energy by intentional whirl and/or friction and possibly using a pressure hose having or not having a spring shaft and nevertheless being able to drill open blockages, the connection part (2) is or will be provided with propelling nozzles (3) and the tool head (6) is or will be provided with a coupling part (10) at the front end of the tool head for fastening rotatable tools (11) protruding in the axial direction. |
