Abstract (en)
[origin: WO03003896A1] The invention relates to a vacuum cleaner comprising a frame mounted on transport members (R, R') and provided with an electric turbine (T) which is used to create a depression, via a membrane filter (M), in a collector (S) of particles recovered from the ground and driven towards said collector by a flow of air via a transfer conduit (C), characterized in that said turbine (T) comprises a set of blades (P) and a nozzle (1) whereby the casing thereof consists of an upstream (11) volute which is centered on the axis of the blades and which leads to a divergent downstream part (12) which communicates with the outside.
