a brush core; and

at least ten bristle clusters regularly distributed over a circumferential surface of the brush core,

wherein the bristle clusters are arranged in at least two parallel planes on the brush core and wherein a respective plurality of the bristle clusters are positioned in each plane, and

wherein tips of all the bristle clusters of each of the at least two planes lie substantially on a common enveloping circular line.

2. The side brush of claim 1, further comprising an alternating arrangement of the bristle clusters in the at least two planes.
