PROBLEM TO BE SOLVED: To additionally provide a blow function rationally and sanitarily no matter what suction generator is used, and to provide a vacuum cleaner with such improved handleability that dust suction conditions are easily recognized. SOLUTION: An air jetting device includes: a suction chamber 6 where suction force acts; a jetting chamber 11 communicating with a jetting port 7 for jetting air; a suction fan 5 disposed in the suction chamber 6 and operated by the suction force; a jetting fan 10 disposed in the jetting chamber 11, for generating jetting force; power transmission means (rotary shaft 14) for transmitting the power of the suction fan 5 to the jetting fan 10; and power generation means 17 connected to the power transmission means. A suction port 2 communicating with the suction chamber 6 is provided on the rear part near the jetting port 7, dust detection means 19 which uses the power generation means 17 as power source is provided, and dust sucked from the suction port 2 is detected by the dust detection means 19 and reported. Even in a place where it is not easy to perform cleaning and it is hard to see the conditions of a surface to be cleaned, since the detected result of the dust detection means 19 is reported, dust recovery conditions are easily recognized and cleaning is efficiently performed.
