Abstract
A waste recuperating electrical apparatus (13) composed of a suction device that includes in particular an electric motor (20) and a suction turbine (22), a suction aperture (16a), and a tubular filter (1) forming a waste receptacle. The apparatus (13) further has a housing (14) arranged between the suction aperture (16a) and the suction turbine (22) with both of which it communicates on either side through ducts (16b) and the tubular filter (1) is arranged in the housing (14) such that one of its end orifices (6) is sealed and the opposite end orifice (4) is directly connected to the suction nozzle duct (16b). The filter housing has elements maintaining (3) the filter spaced from the filter (1) housing (14) inner wall so as to increase the volume around the duct enclosing the filter periphery in the suction turbine direction.
