PROBLEM TO BE SOLVED: To provide a vacuum cleaner capable of improving dust separation performance without enlarging a device.SOLUTION: A vacuum cleaner 1 includes an electric blower 10, a suction port body 2, and a dust collection unit 13. The dust collection unit 13 includes a revolution chamber 29, a main inflow air passage 27, outer air intake ports 56, and sub-inflow air passages 28. The revolution chamber 29 revolves air that has come from a main inflow port 42 and air that has come from sub-inflow ports 45. The main inflow air passage 27 allows air that has passed the suction port body 2 to flow from the main inflow port 42 into the revolution chamber 29. The sub-inflow air passages 28 allow air taken in from the outer air intake ports 56 to flow from the sub-inflow ports 45 into the revolution chamber 29.SELECTED DRAWING: Figure 13 |
