The dredging apparatus comprises a drive motor, a pumping device and an ejector, the drive motor being adapted to drive the pumping device which, in turn, is adapted to deliver a forced flow of water to the ejector in order to establish and maintain the ejecting effect. The ejector, pumping device and drive motor are assembled to form a unit. A cable delivers energy to the motor from the surface.
