Abstract
A floor washing-drying machine including a scraping device that is capable of automatic orientation. The scraping device follows changes of direction of the machine by a simple and effective orienting mechanism so as to wipe all the surface washed by a washing mechanism, without leaving any wet portions on the surface. An idle mode mechanism is achieved by a bushing to which the scraping device is connected. The bushing is mounted in an idle and axially slidable mode on the brush rotation shaft.
