1. A cleaner comprising:
- a base and a subsidiary suction device respectively provided with suction ports to suck external foreign substances;
a suction fan generating suction force to suck the external foreign substances;
a first channel connected to the base to transmit the suction force to the base;
a second channel connected to the subsidiary suction device to transmit the suction force to the subsidiary suction device; and
a channel conversion device including a first valve and a second valve rotated to respectively open and close the first channel and the second channel,wherein the first valve and the second valve are respectively rotated from the upstream portion of a flow to the downstream portion of the flow, and thus close the first channel and the second channel.
