The invention relates to a cleaning device (9) for the surface (3) of a faça de of a building (1). Said device comprises at least one elongated wiper strip unit (10), which can be displaced back and forth along at least one guide ra il unit (6) by means of a fixed drive motor (45) and which extends at right angles to said guide rail unit (6). The device also comprises at least one cleaning fluid line (29), to which spray nozzles (31) that are directed onto the surface (2) to be cleaned are connected. The aim of the invention is to provide a simple, compact device. To this end, the wiper strip unit (10) has at least one carrier (19) which is guided in a sliding manner in the guide rail unit (6). Said carrier is rigidly connected to a linear drive element (32), e.g. a toothed belt (33), which can be displaced along the guide rail unit (6). The fixed drive motor (45) is allocated to said linear drive eleme nt.
