In order to create a wet-cleaning appliance which, as far as the user is concerned, can be transferred in a particularly convenient and reliable manner from mopping operation to regeneration operation, the displaceable covering element should be coupled to the cleaning roller by a gear mechanism, in particular a toothed gear mechanism, such that the cleaning roller can be displaced by virtue of the covering element being displaced or the covering element can be displaced by virtue of the cleaning roller being displaced. ## Claims ### Claim 1 A wet-cleaning appliance (1), in particular a wet mop, having a cleaning roller (2) mounted so that it can rotate around a roller axis (3), and a roller cover (4) that at least partially encloses the cleaning roller (2) in a circumferential direction, which has at least one displaceable covering element (5) for optionally closing and/or releasing an opening region (6) of the roller cover (4), wherein the displaceable covering element (5) is coupled with the cleaning roller (2) by a gear mechanism (7), in particular a toothed gear mechanism, in such a way that the cleaning roller (2) can be displaced by displacing the covering element (5), or the covering element (5) can be displaced by displacing the cleaning roller (2), wherein the covering element (5) is displaceable in a circumferential direction of the cleaning roller (2) around a covering axis (8). ### Claim 2 (depends on 1) The wet-cleaning appliance (1) according to claim 1, wherein the covering element (5) is rotatable around the roller axis (3). ### Claim 3 (depends on 1) The wet-cleaning appliance (1) according to claim 1, wherein the roller axis (3) is arranged on a swiveling arm (15) that is mounted on a housing (10) of the wet-cleaning appliance (1) and can pivot around a swivel axis (9). ### Claim 4 (depends on 3) The wet-cleaning appliance (1) according to claim 3, wherein the gear mechanism (7) is arranged at least partially on the swiveling arm (15). ### Claim 5 (depends on 3) The wet-cleaning appliance (1) according to claim 3, wherein the covering element (5) has a first gear mechanism element (11), and the housing (10) of the wet-cleaning appliance (1) has a second gear mechanism element (12). ### Claim 6 (depends on 5) The wet-cleaning appliance (1) according to claim 5, wherein the first gear mechanism element (11) engages into the second gear mechanism element (12), wherein the swiveling arm (15) has a covering axis (8), in particular the roller axis (3), on which the covering element (5) is rotatably mounted. ### Claim 7 (depends on 5) The wet-cleaning appliance (1) according to claim 5, wherein a third gear mechanism element (13), in particular a toothed wheel, is arranged on the swiveling arm (15), which engages into the second gear mechanism element (12), and wherein the gear mechanism (7) further has a fourth gear mechanism element (14), in particular a toothed wheel, which is connected with the third gear mechanism element (13) in a force-transmitting manner, and engages into the first gear mechanism element (11). ### Claim 8 (depends on 3) The wet-cleaning appliance (1) according to claim 3, wherein a drive, in particular an electric motor, is allocated to the swiveling axis (9) of the swiveling arm (15) or one of the gear mechanism elements (11, 12, 13, 14). ### Claim 9 (depends on 3) The wet-cleaning appliance (1) according to claim 3, wherein the housing (10) has a first slotted guide (16), into which an engaging element (17) arranged on the covering element (5) engages. ### Claim 10 (depends on 9) The wet-cleaning appliance (1) according to claim 9, wherein the covering element (5) has a second slotted guide (18), into which an engaging element (19) arranged on the housing (10) engages. ### Claim 11 (depends on 1) A method for operating the wet-cleaning appliance (1) according to claim 1, wherein a rotatable cleaning roller (2) for a regeneration operation of the cleaning roller (2) is displaced away from a surface to be cleaned, and is at least partially enclosed with a roller cover (4), wherein the cleaning roller (2) is displaced by a displacement of a covering element (5) of the roller cover (4), or the covering element (5) is displaced by a displacement of the cleaning roller (4), in particular by means of a gear mechanism (7) that provides an operative connection between the covering element (5) and cleaning roller (2), wherein the covering element (5) is displaced in a circumferential direction of the cleaning roller (2) around a covering axis (8).
