The tube shaft is either shaped as a cyclone separator or a cyclone separator is arranged between the nozzle and the tube handle. The cyclone separator is provided with a whirl chamber (37) which is defined, in part, by an up-side-down truncated cone (41). The whirl chamber has an inlet opening (38), a first outlet opening and a second outlet opening. The inlet opening is placed at the upper part of the whirl chamber (37). Partially cleaned air flows through the first outlet opening (39) which communicates with the vacuum source. The second outlet opening (42) is placed at the lower part of the whirl chamber. The second outlet opening communicates with a dust collecting container (43).
