AbstractA device for cleaning materials attached to a vessel and a building structure below water level is provided which comprises a generally cylindrical outer shell and a central chamber arranged concentrically within the outer shell, the chamber having an impeller for discharging the attached materials together with water through a circular space between the outer wall of the chamber and the inner wall of the shell, and a cleaning device for removing the materials on the surface of the vessel and the structure. In operation of the impeller the device is absorbed and adhered onto a cleaning surface of the vessel and the building structure whereby cleaning operation can be effected without the device being pressed onto the cleaning surface.
