Flushing-dump arrangement for cleaning the bottom of sewage basins, rainwater basins or the like, which has at least two tanks which are tiltable by filling with water and are connected to one another so as to be fixed in terms of rotation. To avoid water losses on filling the tanks and therefore in order that each tank empties its intended quantity of water on tilting, they are connected so as to communicate with one another through at least one water conduit.
