Abstract: A toilet seat (27) is provided with a slide housing (26) comprising nozzles for spraying and/or applying water and/or disinfecting liquid. It comprises at least one wiper for drying the surface of the seat (27). The slide housing (26) is placed over a segment of the seat (27), which then, while being sprayed by the nozzles, is driven in the circumferential direction by at least one electric motor. The entire operation is started up manually by actuating the lever (2) of the flushing water cistern (1), and subsequently is controlled by the control electronics (27) until the cleaning of the seat (27) has been completed. The energy is obtained by a turbine (11), which is mechanically connected to a low-voltage direct-current generator (13), and is driven by the water filling the flushing water cistern (11). The actual flushing water, therefore, flows at the normal kinetic energy into the toilet; the hydraulic resistance of the turbine (11) is not switched on while the flushing water flows into the toilet bowl.
