LENS CLEANING WITH FLEXURAL ACTUATOR

The invention relates to a cleaning device for cleaning an optical device of a motor vehicle, wherein the cleaning device has at least two cleaning units and at least one holder on which the cleaning units are arranged. Each cleaning unit has a drive part and a cleaning part, wherein the drive part comprises an electroactive polymer and can move the cleaning part at least partially. The holder on which the cleaning units are arranged is movable between a working position in which the cleaning units are positioned toward the optical device such that the cleaning parts can be moved by the drive part over a surface to be cleaned of the optical device, and a rest position in which the cleaning units are positioned away from the optical device. The cleaning device is configured such that each cleaning part of the cleaning units is moved over a partial area of the surface to be cleaned assigned to it, wherein the partial areas can at least partially overlap.
