The device serves for eliminating deposits (52) in ventilation ducts (14) in the stationary or non-stationary operating mode. The cleaning medium is a fluid sprayed out under high pressure from a spray head (3). The spray head (3) is carried by a supply pipe (2), through which lead the drive shaft coming from a motor (1) and a fluid channel. In the non-stationary operating mode, the device is integrated into a slide (15) which is pulled through the ventilation duct (14). The slide (15) is introduced into the ventilation duct (14) through an inspection port sealable by means of an inspection cover. Ventilation ducts (14) extending horizontally, vertically and obliquely can be treated. In the stationary operating mode for cleaning an inlet or outlet, a bend or a branch and, for example, also a vapour extractor, the device is held without a slide (15) in a supporting cover which is inserted into the inspection port.
