SELF-PROPELLED APPARATUS FOR CLEANING A SUBMERGED SURFACE

摘要

The invention relates to a self-propelled apparatus for cleaning a submerged surface, comprising: a hollow body (1); a device (2, 11, 14) for guiding and driving the hollow body (1) over the submerged surface, said hollow body (1) including a base (3) positioned facing the submerged surface; at least one liquid inlet (4); and at least one member projecting from the base of the hollow body toward the submerged surface. The invention is characterised in that it includes at least one member, referred to as the anti-blocking member (6), positioned immediately in front of a projecting member (7) in a direction of movement of the hollow body (1), said member rotating about a rotation shaft (10) which is fixed relative to the projecting member (7). The anti-blocking member (6) can roll over an obstacle on the submerged surface and move the projecting member (7) such as to get over the obstacle.
