  • the barrelled body 130 is inserted into the dust collecting unit 200 so as to slide.
  • the barrelled body 130 and the dust collecting unit 200 can move with respect to each other. That is, if the user pulls or pushes a handle 101 on a upper surface of the cyclone unit 100 far from or toward the dust collecting unit 200, the barrelled body 130 slides along the inside of the dust collecting unit 200. Therefore, the dust collecting space (S) can be selectively increased or decreased according to change of positions of the barrelled body 130 and the dust collecting unit 200.
  • a seal ring 131 is formed along the circumference of a lower portion of the barrelled body 130 so as to make the dust collecting device airtight, thereby preventing loss of pressure.

Accordingly, in order to widen the dust collecting space (S), if the user pulls the cyclone unit 100 upwards at a predetermined distance, the hooking protrusion 260 prevents the dust collecting unit 200 from moving upwards together with the cyclone unit 100. Consequently, the dust collecting space (S) can be smoothly widened.
