Abstract
To provide a vacuum cleaner capable of effectively preventing damage to a fan and a fan case without significantly decreasing the suction force. The vacuum cleaner includes a suction portion, a centrifugal separation portion, and a first collection portion that are provided on an upstream side of a fan stored in a fan case; and a second collection portion provided on a downstream side of the fan. The vacuum cleaner is configured to, with rotation of the fan, separate a part of air introduced into the centrifugal separation portion via the suction portion to the first collection portion side, thereby collecting sucked objects contained in the air into the first collection portion, and separate another part of the air introduced into the centrifugal separation portion to the fan side, thereby collecting sucked objects contained in the air into the second collection portion.
