PROBLEM TO BE SOLVED: To provide a floor brush securing a cleaning performance of a brush member and a blade member, and having a preferable maintainability. SOLUTION: A driving device 81 is rotationally driven by a motor 13 to connect one end in the axial direction of a brush mount 51 and the driving device 81, and torque load of a second bearing 98 on the other end of the brush mount 51, which is larger than that of a first bearing 91 on the driving device 81, causes a circumferential twist of the elastic brush mount 51 with a brush member and a blade member 53 to rotate a rotary brush 12, so that the cleaning performance of the brush member and the blade member 53 is secured. The motor 13 stops to disconnect a driven device 54 of the brush mount 51 and the driving device 81, the elastic brush mount 51 is returned and changes its form, and the brush member and the blade member 53 follows the axial direction of the brush mount 51 for preferable maintainability.
