A self-propelled running apparatus for cleaning a surface immersed in a liquid, includes a tranverse running member having two ends through which it is mounted rotatable on a frame about a tranverse axis of rotation, a device for driving in rotation the member and a frame-mounted guide borne by the frame. The guide is adapted to enable, without dismantling relative to the frame the frame-mounted guide and without dismantling the frame itself, at least the displacement of the running member between a working position and a maintenance position. |
