摘要

The method involves applying a cleaning liquid (R) to a surface to be cleaned using spray nozzles (15, 16), where the liquid forms a continuous liquid film on the surface and dust particles are washed away by the film. A sanitary appliance (10) or the surface are excited using ultrasonic exciters (13) in an oscillating manner, where the exciters are incorporated into the appliance and the excitation of the surface takes place in a frequency spectrum of 20-40 kilohertz.
