A vacuum cleaner of the present invention guides air and dust sucked from an inlet 12 to a dust collection chamber 29 through a guide path 41 . A cylindrical passage member 55 is locate data linear section of the guide pipe 41 so that its axial line may come along a direction in which the linear section 52 extends. A plurality of vent holes 47 are formed on the passage member 55 and each of the vent holes 47 is covered with a mesh filter 50 . When dust is accumulated in the dust collection chamber 29 to some extent, air flowing into a lead-in pipe 43 flows to the outside (the side of a bypass passage 31 ) through the vent holes 47 and is guided directly to an outlet by bypassing the dust collection chamber 29.
