PROBLEM TO BE SOLVED: To provide a suction nozzle for a floor for a vacuum cleaner enhancing a dust collecting effect by blowing intake air of a turbine on a floor surface. SOLUTION: When cleaning is performed by operating a vacuum cleaner, air flows from an air intake port 12 to the turbine 9 to rotate the turbine 9. A rotary brush 7 rotates by synchronizing with the rotational force. At the same time, intake air rotating the turbine 9 becomes air flow 16, is led to an intake air flow passage 11 including a turbine chamber formed by the rotary brush 7 and a partition wall 10 between the turbine 9 and a front surface of the rotary brush 7 and is blown from a plurality of intake blowoff ports 15 provided in the vicinity of the floor surface of the partition wall 10 on the front surface of the rotary brush 7 to the floor surface. By blowing air to the floor surface of a suction port 6, dust on the floor surface and a carpet is flung up, and air is passed through a bent joint 4 and is sucked into a cleaner main body together with dust scraped up by a blade 13 of the rotary brush 7.
