An arrangement for cleaning of pipelines, and especially ventilation pipes and ventilation ducts in buildings, by means of a cleaning means, which is connected via a supply conduit with a source of pressure medium showing one or more nozzle openings directed back towards the supply conduit. The cleaning means shows a nozzle opening in the form of a largely continuous annular gap, which extends along the periphery of the cleaning means and which is connected to the supply conduit and the source of pressure medium, by which annular gap the medium is made to discharge in order partly to clean inner walls of the line, and partly, as a result of the forces of reaction from the discharging medium, to make the cleaning means move into the pipeline.
