Abstract

In order to be able to dispense with the time-consuming and expensive manual cleaning of ship's hulls (4), a cleaning installation is proposed which consists of at least one cleaning roller (2, 3) which can be driven to rotate, is rotatably mounted in a rack (1) and whose roller structures are positioned at least partially below the surface of the water.
