ABSTRACT:
A device for cleaning surfaces in general by means of a liquid jet comprises a cleaning liquid entry duct (1) in which a hollow shaft (3) fitted with a drive impeller (9) is rotatably mounted. After traversing the impeller, the liquid enters the shaft to then exit in the form of a compact filiform jet through a nozzle (6) which is inclined to the longitudinal axis of rotation of the shaft. The speed of rotation of the shaft and hence of the jet can be adjusted at will from zero to a maximum value by a braking unit (23, 24). There is also provided a selector (88) arranged to assume a first position in which it enables all the liquid to enter the hollow shaft, and a second position in which part of the liquid is deviated upstream of the impeller and discharged downstream of the impeller as an atomized conical jet.
