The brush body 300 includes a first brush strip 360 located on the outer side and a second brush strip 364 spaced apart from the first brush strip 360 and made of a different material. The first brush strip 360 rotates around the axis of the brush body 300 to form a first brush strip virtual rotation circle, while the second brush strip 364 rotates around the axis of the brush body 300 to form a second brush strip virtual rotation circle. The diameter of the second brush strip virtual rotation circle is greater than or equal to the diameter of the first brush strip virtual rotation circle.

[0024] The rolling brush body 300 further comprises a rolling brush sleeve 320 located at the inner side, a driving end 304 located at one end, a plurality of mounting portions 340 circumferentially spaced around the rolling brush sleeve 320, and a plurality of circumferential gaps 342 located between adjacent two mounting portions 340. The mounting portion 340 comprises a first mounting groove 344 receiving a first brush strip 360, and a second mounting groove 348 located adjacent to the first mounting groove 344 and receiving a second brush strip 364, wherein the extending directions of the first mounting groove 344 and the second mounting groove 348 are parallel to the central direction of the rolling brush body 300. The axial section of the first mounting groove 344 and the second mounting groove 348 is a T-shaped groove. The first brush strip 360 is a wool strip comprising a plurality of bristles, and the diameter of the bristles is 0.1-0.6mm, and the material of the bristles is nylon fiber. The second brush strip 364 is a leather strip, and the material of the second brush strip 364 is rubber.
