A wet cleaning device, in particular a wet wiping device, has a cleaning roller which is rotatable about a roller axis and has a cleaning lining. In order to create a wet cleaning device in which the regeneration effect is optimized, in particular while using a minimum of liquid, the wet cleaning device has a decelerating element to assist the removal of liquid and/or of dirt from the cleaning roller, which element has an impact edge directed radially outwards with respect to the roller axis and is arranged between fibers of the cleaning lining during a regeneration operation in such a way that the free ends of the mechanically unloaded fibers project outwards in the radial direction beyond the impact edge.
A wet-cleaning device (1), having a cleaning roller (3) that can rotate around a roller axis (2), and has a cleaning lining (4) with fibers (6) having free ends, wherein the wet-cleaning device (1) has a decelerating element (5) to support the removal of liquid and/or dirt from the cleaning roller (3) during a regeneration operation, wherein the decelerating element (5) has an impact edge (7) relative to the roller axis (2), and during the regeneration operation is arranged so as to radially cover the fibers (6) of the cleaning lining (4) to such an extent that the free ends (8) of the mechanically unloaded fibers (6) outwardly protrude over the impact edge (7) in a radial direction, wherein the decelerating element (5) has an expansion that yields a distance between the decelerating element (5) and the roots of the fibers (6) and a distance between the free ends (8) of the fibers (6) extending in a radial direction and the decelerating element (5), so that the free ends (8) of the fibers (6) have leeway to bend over the impact edge (7) given an impact on the impact edge of the decelerating element and to be pulled off of the impact edge (7) in the direction opposite the bending as the cleaning roller (3) continues to rotate and be guided through between the cleaning roller (3) and decelerating element (5).
A method for operating a wet-cleaning device (1) wherein liquid and/or dirt are removed from a cleaning roller (3) of the wet-cleaning device (1) rotating around a roller axis (2) during a regeneration operation, wherein a decelerating element (5) for the regeneration operation is arranged so as to radially cover fibers (6) of a cleaning lining (4) of the cleaning roller (3) to a point where an impact edge (7) of the decelerating element (5) protrudes so far between the fibers (6) that the free ends (8) of the fibers (6) are folded over the impact edge (7) during the rotation of the cleaning roller (3), wherein the decelerating element (5) has an expansion that yields a distance between the decelerating element (5) and the roots of the fibers (6) and a distance between the free ends (8) of the fibers (6) extending in a radial direction and the decelerating element (5), so that the free ends (8) of the fibers (6) have leeway to bend over the impact edge (7) given an impact on the impact edge (7) of the decelerating element (5), and to be pulled off of the impact edge (7) in the direction opposite the bending as the cleaning roller (3) continues to rotate, and be guided through between the cleaning roller (2) and decelerating element (5).
