<p>The apparatus (5) has a cylindrical head (1) equipped with active elements e.g. cleaning units such as fluid diffusion units and cleaning wipe (2), and a residual fluid collection unit such as scraper strip (3) and a suction mouth (4). The active elements for cleaning are placed on a side of the head, and the elements for collecting the residual fluid are placed on another side of the head with respect to a median longitudinal plane, where the apparatus is formed to alternatively use the elements required to clean or to collect the residual fluid.</p> |
