Abstract

A cleaning section for an electric oral hygiene device is disclosed. The cleaning section includes at least a first carrier mounted for driven rotation or oscillating rotation around a rotation axis; and at least a plurality of first cleaning elements mounted on the first carrier with their bases arranged on the vertices of a first star-shaped polygon around the rotation axis. All of the first cleaning elements are inclined in a circumferential direction such that the free end of each of the first cleaning elements is farther away in the circumferential direction than the base of the respective first cleaning element; and wherein at least one cleaning element property alternates between adjacent first cleaning elements or between clusters of first cleaning elements.
