The invention provides a sensor device with a cleaning function. A sensor device includes a cylindrical sensor window defining an axis; and a ring fixed relative to the sensor window and centered about the axis. The ring includes a liquid chamber, at least one nozzle, and an air chamber. The liquid chamber is circumferentially elongated about the axis. The at least one nozzle is fluidly connected to the liquid chamber and has a discharge direction directed at the sensor window. The air chamber is circumferentially elongated about the axis alongside the liquid chamber. The air chamber does not have an inlet and an outlet.
