PROBLEM TO BE SOLVED: To provide a vacuum cleaner having a cyclone duct collecting machine which can efficiently collect the bulky dust while preventing the bulky dust from being adhered to an inner surface of an external wall of an outer cyclone chamber as much as possible, and easily dispose the accumulated dust with the excellent dust collection volume efficiency of the bulky dust. SOLUTION: (1) A pocket is provided in the external wall of the outer cyclone chamber. (2) A bulky dust accumulation chamber communicated with the pocket is provided on a lower portion of the pocket. (3) A small dust accumulation chamber is provided on a lower portion of an inner cyclone chamber. (4) The bulky dust accumulation chamber is attached/detached to/from a cyclone unit comprising the outer cyclone chamber and the inner cyclone chamber. (5) The small dust in the small dust accumulation chamber is discharged into the bulky dust accumulation chamber when the bulky dust accumulation chamber is detached from the cyclone part.
