PROBLEM TO BE SOLVED: To provide a rotary rotor which can be manufactured easily with improved precision to prevent the deflation of the rotor when rotating. SOLUTION: In the vacuum cleaner floor nozzle set in the main body case, which has the oblong opening for sucking dust at the bottom, the rotary rotor is provided in the vicinity of the opening. The rotary rotor consists of a rotor and a cleaner. The rotor has plurality of grooves, which open to the both ends and are parallel to the direction of the axis. The cleaner consists of plurality of base parts and cleaner blades, which are connected to the base parts. The base parts are attached to the rotor grooves in a way that the cleaner blades are mounted around the rotor axis successively with a specified torsion angle.
