Further, by operating and moving the operation pipe 40S to adjust the height position of the ejection nozzle 50, it is possible to wind up only dust such as fallen leaves having a light weight without rolling up stones and mud. Further, even if stones or mud rolls up, by operating and moving the operation pipe 30S to adjust the height position of the guide member 33, only dust such as fallen leaves having a light weight is sucked into the suction port 31 of the connection pipe 30. You can surely inhale.

Further, since the guide member 33 prevents the suction port 31 of the connection pipe 30 from coming into direct contact with the ground or the like, it is possible to prevent stones or mud from being directly sucked from the suction port 31.

Dust such as fallen leaves sucked from the suction port 31 of the connection pipe 30 is the air passage 3 on the nozzle side of the connection pipe 30.
It is sucked into the dust collection case 60 through 0a. In the dust collection case 60, a vortex flow is generated by the cyclone portion 63, and relatively large dust such as fallen leaves accumulates at the bottom of the dust collection case 60 due to this vortex flow.

The air and small dust sucked into the dust collecting case 60 passes through the filter 64 and is sucked into the dust collecting chamber 21 of the cleaner body 20 through the body side air passage 30B of the connection pipe 30. Then, small dust is collected by the dust collecting filter 23.

As described above, relatively large dust such as fallen leaves is collected in the dust collection case 60, and small dust is collected by the dust collection filter 23 of the cleaner body 20, so that the dust collection filter 23 is frequently replaced. You don't have to.

In order to discard the fallen leaves accumulated in the dust collecting case 60, the dust collecting case 60 is removed from the connection pipe 30 and the filter 64 is removed to discard the fallen leaves.

In the above embodiment, the bottom wall guide portion 33A of the guide member 33 is plate-shaped, but may be comb-shaped or brush-shaped. Further, as shown in FIG. 5, a part of the side wall guide portion 73B of the guide member 73 may be a wire mesh, and the upper wall guide portion 73C may be a wire mesh.

Further, in the above embodiment, the power source is taken from the power cord, but it may be a battery type.
