Abstract
A sweeping brush for an automatically moving cleaning device has a rotational axis receptacle for receiving a rotational axis of the cleaning device and at least one bundle receptacle that extends outwardly from a transition area on the rotational axis receptacle, which holds a bristle bundle having a plurality of bristles. The bundle receptacle is arched as viewed in an axial direction of the rotational axis receptacle. In order to optimize known sweeping brushes in terms of their service life and cleaning properties, the bundle receptacle is fabricated out of an elastic material.
