The present invention refers to a floor cleaning machine comprising brush means (2) adapted to scrub the floor (4) with a cleaning, i.e. detergent 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) comprises 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, wherein said suction chamber is fluidly connected to suction means (8), and wherein said front flap (5) is provided with a plurality of indentations (9) of a reduced cross-sectional size to convey the dirty cleaning liquid into the suction chamber (7); at least a portion of the front flap (5) is provided in the form of a tab (10) that is associated to the same front flap (5) via a rupture edge (11), wherein such tab (10) is adapted to be removed so as to form a breach or passageway (12) having a broader cross-sectional size in the front flap (5) in order to reduce the speed of the air entering the suction chamber (7) and, as a result, the related suction noise. A method for manufacturing a scraping flap is also provided. |
