A device configured to generate a liquid jet on an outer region of a motor vehicle, the device comprising:

• a tank of the motor vehicle;
• a pump of the motor vehicle coupled to the tank;
• a liquid outlet of the motor vehicle coupled to the pump, wherein the liquid outlet is configured to emit the liquid jet generated by the pump and fed from the tank so that the liquid jet emerges in the outer region of the motor vehicle;
• a liquid container with a liquid inlet configured to receive the liquid jet from the liquid outlet in the outer region of the motor vehicle, wherein the liquid container is coupled to the tank via a conduit.

A method for operating a device configured to generate a liquid jet on an outer region of a motor vehicle, the device comprising a tank of the motor vehicle and a pump of the motor vehicle coupled to the tank, the method comprising:

• generating, by the pump, a liquid jet using fluid feed from the tank;
• emitting, by a liquid outlet of the motor vehicle coupled to the pump, the liquid jet in the outer region of the motor vehicle;
• receiving, by a liquid container with a liquid inlet, the liquid jet emitted by the liquid outlet in the outer region of the motor vehicle, wherein the liquid container is arranged in the outer region of the motor vehicle;
• and
• providing, by the liquid container via a conduit, fluid received from the liquid jet to the tank.
