A cleaning unit for a window or a sensor in a motor vehicle includes a reservoir for a cleaning liquid, at least one cleaning nozzle provided in or on a cleaning nozzle unit, a fluid connection between the reservoir and the cleaning nozzle and at least one spray pump provided between the reservoir and the cleaning nozzle. The spray pump is formed by a piston-cylinder unit that has a cylinder axis and is provided in or on the cleaning nozzle unit. The cleaning unit is characterized in that the piston of the piston-cylinder unit is designed as an electromagnetically actuated piston, which can be actuated in a first direction under the action of an electromagnetic force directed along the cylinder axis, which first direction forms a compression direction.
