1. A sensor cleaning device for cleaning an external vehicle sensor device from above, the sensor cleaning device comprising,
a liquid inlet for receiving pressurized liquid,
a first and a second liquid outlet for emitting pressurized liquid which is received from the liquid inlet,
a chamber for pressurized liquid fluidly connecting the liquid inlet and the first and second liquid outlets,
wherein each one of the first and second liquid outlets is having a width and a length, wherein the length extends in a length direction and the width extends in a width direction, wherein the length direction is perpendicular to the width direction, and wherein the first and second liquid outlets are configured so that pressurized liquid is emitted transversely through a sectional plane defined by the width direction and the length direction, characterized in that, the length is greater than the width for each first and second liquid outlet so that a first and second line-shaped liquid outlet is formed, the chamber having a first volume fluidly connected to the first line-shaped liquid outlet and a second volume fluidly connected to the second line-shaped liquid outlet, wherein the first and second volumes extend in a circumferential direction to form a tubular structure providing dual channel flow of the pressurized liquid,
the first and second line-shaped liquid outlets are further configured so that emitted pressurized liquid therefrom during use impinge each other, thereby forming a resulting sheet of liquid,
a gas inlet for receiving pressurized gas and at least one gas outlet for emitting pressurized gas which is received from the gas inlet,
wherein the at least one gas outlet is provided in-between the first and second line-shaped liquid outlets.
