A washing system (100) is intended for washing a surface (210). It includes at least two fluid-ejection devices (110, 120) adapted to discharge fluid out of the device to the surface (210). The fluid-ejection devices (110, 120) are positioned relative to each other such that a turbulence effect is created when fluid is discharged out of the fluid-ejection devices (110, 120) towards the surface (210) being washed. The fluid-ejection devices (110, 120) can be positioned opposite each other, such that fluid discharged encounters with adjacent areas in the surface (210) being washed.
