  • Patent number: 9516985
    Abstract: A washing-drying machine including a scraping device including a reversible fastening system of scraping blades. The reversible fastening system makes it possible to apply the scraping blades to the scraping device in a simple and safe way and as simply to remove them to clean them or replace them when worn out through a flexible fastening mechanism including holes for engaging with support elements provided on the scraping device, and including at least an elastic end portion with a slot for engaging with the undercut of a corresponding locking element, formed in the proximity of end portions of the support.

  • Patent number: 8549702
    Abstract: The present invention refers to a floor washing-drying machine, in particular of the drives-on-board kind, provided with at least a front driving and steering wheel (3), a pair of rear wheels (5), a brush-carrying head (4) positioned between the front driving wheel and the supporting axle of the rear wheels, and a wiping and vacuuming device (6) arranged behind the rear wheels. The brush-carrying head (4) is connected with the machine frame through a support and steering system of four-arm linkage type (X,Y,J,W; 17,19) which is driven by a gear steering device (11,12,14,15). The technical solution allows to solve efficiently the problem of collecting washing liquid and to dampen impacts of the machine against obstacles which it may encounter along its path.

  • Patent number: 7743459
    Abstract: A floor washing-drying machine includes a brush (2) adapted to scrub a floor (4) with a cleaning liquid in view of removing soil and dirt therefrom, and a wiping device (3) adapted to scrape the floor (4) in order to remove the dirty cleaning liquid therefrom. The wiping device (3) includes a front flap (5) and a rear flap (6) adapted to elastically and slidably engage the floor (4) so as to define a suction chamber (7) therebetween, with the suction chamber being fluidly connected with a suction device (8). A further elastic flap (10) is mounted to the wiping device behind the rear flap, and the width of the further flap is smaller than the width of the front and rear flaps (5, 6).
