Apparatus for cleaning a submerged surface with a disconnectable dirty circuit

Abstract

The invention relates to a device for cleaning an immersed surface comprising a hollow body and members for driving the body over the immersed surface; a filtration chamber which is provided in the hollow body and which has: a liquid inlet; a liquid outlet; a hydraulic circuit for the flow of liquid between the inlet and the outlet through a filtering device (11), wherein the filtering device (11) comprises a filtering casing (49, 55) which is removably mounted in the filtration chamber and which can be inserted into/removed from the filtration chamber in one piece, and the filtering casing (49, 55) has at least a lower end which opens at the base of the hollow body and which constitutes a liquid inlet into the hollow body of the device.
