| 摘要 |
The invention concerns a self-propelled running apparatus for cleaning a surface immersed in a liquid, comprising at least a transverse running member (15), having two axial ends through which it is mounted rotatable on a frame about a transverse axis of rotation, means guiding in rotation said running member, including means driving in rotation said member through at least one of its axial ends, and whereof a part at least, called frame-mounted guide means, is borne by the frame. Said cleaning apparatus is characterised in that the guide means are adapted to enable, without dismantling relative to the frame the frame-mounted guide means and without dismantling the frame itself, at least the displacement of the running member (15) between a position, called working position, wherein the running member co-operates with the guide means so as to be driven in rotation about the transverse axis, and a position, called maintenance position, adapted to enable at least one component (21, 22) forming a running surface of the running member to be changed.
