PROBLEM TO BE SOLVED: To provide a suction nozzle capable of enhancing dust-sucking performance and serviceability and reducing the rate of dust clogging when sucking dust and the rate at which dust on a floor face to be cleaned is blown away. SOLUTION: A connection 101 rotatably connected to a suction nozzle body part 102 includes an inner connecting pipe 105 for suction, having an inlet 105c facing an intake port 129 through which air is sucked, an outer connecting pipe 106 having the pipe 105 inside it, and a return air passage 107 formed between the pipes 105, 106 and having pivot parts 109 that form a pair of horizontally projecting return air passage outlets. An air guide 135 is provided at a front edge portion 122b adjacent to the upstream of a circulation blowout port 103 through which the air circulated is forced out to the intake port side. The collision between two streams of air, supplied to the blowout port 103 while facing each other after being separated by the pair of outlets 109 inside the main part 102, is prevented by the air guide 135 to restrain generation of turbulent flow.
