By the rotation of the rotating brush 37, dust adhering to the surface to be cleaned is scooped, and the scavenged dust passes through the extension pipe 24 from the suction port 35 and is sucked into the dust collection chamber 31. The dust sucked into the dust collection chamber 31 is
The intake air is separated by a vortex generated by flowing from the extension pipe 24 along the outer wall in the dust collection chamber 31, and only the intake air from which dust has been removed is sucked into the electric blower 21 via the hose 23. Here, in the present embodiment, the dust collecting chamber 31 for collecting dust is provided at the connecting portion between the hose and the extension pipe, and this is provided between any of the ventilation passages from the suction tool 22 to the electric blower 21.

It is a vacuum cleaner and uses a cyclone dust collection method so that dust is not clogged unlike a rechargeable vacuum cleaner with a dust collection bag, so that a constant suction force can be maintained and the battery capacity can be maintained. However, it is possible to improve the dust collection performance of the rechargeable vacuum cleaner, which is limited and does not easily suck dust with only suction power.
