Claim Text:
1. A cleaning section for an electric oral hygiene device, comprising: 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 a mounting surface of the first carrier with their bases arranged on vertices of a first star-shaped polygon around the rotation axis; wherein all of the first cleaning elements are circumferentially inclined in the same circumferential direction with respect to the rotation axis such that a 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; wherein the first cleaning elements form an outermost ring of a plurality of rings of cleaning elements; wherein at least one first cleaning element has a first height measured between the mounting surface of the first carrier and the free end of the first cleaning element in direction of the rotation axis and at least one first cleaning element has a second height, wherein the distance between the two height values lies in a range of between about 0.1 mm and about 3.0 mm; wherein the shape of the cross-sections of the first cleaning elements alternate between an elongate shape such as an essentially rectangular shape and a more compact shape such as an essentially square shape or an essentially trapezoidal shape; wherein at least one cleaning element property of a length of the cleaning element and an area of a cross section of the cleaning element discretely alternates between adjacent first cleaning elements or adjacent clusters of first cleaning elements; and wherein circumferential inclination angles of at least the first cleaning elements lie in a range of between about 10 degrees to about 16 degrees; wherein the first cleaning elements have an additional penetration amplitude in a relative range of between about 1.5% and 3.9% of the length of the cleaning element.
