a) Cleaning system comprising a suction source connected by a filter unit for filtering the indrawn air to a manifold (9) which has connection points (10) in the areas to be cleaned. b) System characterised in that the filter is composed of a chamber (3), at the top end of which is a pipe (2) connected to the suction source (1) and at the bottom end of which is an emptying port (6) closed by a valve (8), in that the pipe (2) connected to the suction source (1) continues into the interior of the filter chamber in the form of a sleeve (4) with an open bottom end (41) and in that the manifold (9) is connected to the filter chamber by a pipe (16) provided with at least one nozzle (15) for injecting into the stream of indrawn air a jet of atomised water, which pipe (16) enters the chamber more or less tangentially and at a similar height to the sleeve (4). <IMAGE>
