<p>Apparatus for cleaning continuous smooth surfaces comprising a cleaning unit (A) and a seizing unit (B). The cleaning unit (A) comprises suitable rotating brushes (10-30), liquid detergents sprayers (20), sucking manifolds (12-40) and/or blowing manifolds (50), which are operated and co-operating in a per se known manner. The seizing unit (B) comprises a pair of tracks (60) strained between respective pulleys (80-81), which are arranged parallel to each other and operated synchronously by a suitable motor (805), which tracks are provided with a plurality of cups (70) fixed thereto by means of adequate rigid bodies (71), in which discoidal membranes (73) providing for the effective cups are controlled centrally by an associated stem (74), which operates under depression said discoidal membranes (73) at the adherence portion thereof. A further set of tracks (60b) disposed orthogonally to the previous one permits to obtain translations orthogonal to each other. <IMAGE></p> |
