To provide a circulating type vacuum cleaner capable of preventing exhaust air from leaking from the circulating air path of a cleaner main body to the outside through a clearance around a sucking hose, capable of surely preventing the sucking hose from being disconnected, simple in structure, and convenient for increasing the circulating performance of air.

A flexible sucking hose 33 of bellows tube is extracted to the outside of a cleaner main body 12 across a circulating chamber 26 allowing to lead therein the air exhausted from an electric blower and moving to the vent hole 22c of a connection port body 22. The hose 33 communicates the connection port body 22 thereof with a sucking path 22f and stuck fixedly to each other so as to form a second sucking route different from a first sucking route B leading from the sucking port 91 of the sucking port body 13 to a dust collecting chamber 23. A circumferentially continued rib 48 is provided projectedly on the inner surface of the annular hose surrounding part 47 of a main body 12 surrounding the hose 33. The rib 48 is fitted into the groove in the outer periphery of the hose 33 passing through the surrounding part 47.
