PROBLEM TO BE SOLVED: To selectively use respective suction ports according to requirements, easily clean a narrow place and a high place or the like, and at the same time, eliminate an exchange of suction nozzles during cleaning by attaching a main body wherein a plurality of suction ports can be switched, between a switch box and a nozzle. SOLUTION: At one end of a main body 1, a main suction port 7 and a subsidiary suction port 2 are provided, and at the other end, a hose connecting part 15 is provided. Also, in the main body 1, a suction port breaker 6 which blocks either one of respective suction ports 7, 2 is provided, and the suction port breaker 6 is moved along a guide 3 and a groove 4, and at the same time, a switching lever 5 is provided so that the suction port breaker 6 may be operated from the outside of the main body 1. In addition, a subsidiary extension pipe 9 is constituted of a flexible hose 8, and the flexible hose 8 is fixed to a main extension pipe 10 with a pipe fixing utensil 11. By this method, by using a plurality of suction ports 7, 2 which are provided between a switch box and a suction nozzle 12 by selectively opening/closing them, even a narrow place and a high place or the like can be easily cleaned.
