PROBLEM TO BE SOLVED: To provide an exhaust circulation type vacuum cleaner whose hose weight is decreased and whose operability is improved. SOLUTION: A cleaner hose unit 4 structured with double hoses composed of an outer hose 11 and an inner hose 12, has a handle pipe 6 on one end which is provided with an operation section for operating the vacuum cleaner, is communicatively connected on the handle pipe 6 side to a suction nozzle 7 which scrapes up dust, and is provided with a plurality of conductive wires which electrically connects between a body 1 and the operation section dividedly along each of the outer hose 11 and the inner hose 12, whereby the conductive wires disposed on the inner hose 12 which is smaller in diameter than the outer hose 11 are decreased in usage quantity owing to the smaller winding diameter and are decreased in weight, thereby improving operability.
