Device for cleaning a surface by means of jets of liquid, consisting of a rotary assembly (1), arranged inside a protective cap or casing (2), and which is mounted at the end of the output shaft (4) of an engine (motor). It is characterised in that it comprises: - a cylindrical chamber (5) which is concentric and integral with the drive shaft (4), arranged below the protective cap (2) and inside which emerges a supply (6) of cleaning liquid; - at least one circuit (7) extending radially from the abovementioned chamber (5), in the direction of the lateral wall of the protective cap (2) and including orifices making it possible to spray, under pressure, the liquid introduced without pressure inside the rotary chamber (5) in the direction of the surface or surfaces to be cleaned. <IMAGE>
