1. A delivery unit for a cleaning system, the cleaning system for cleaning a sensor system of a Self-Driving Car (SDC), the sensor system and the cleaning system being mounted onto the SDC,
the delivery unit comprising:
a liquid nozzle for delivering a liquid jet and directing the liquid jet towards a surface of the sensor system;
an air nozzle for delivering an air jet and directing the air jet towards the surface of the sensor system; and
a deflection orifice for delivering an other air jet;
the liquid nozzle, the air nozzle, and the deflection orifice disposed in a triangular configuration, wherein in the triangular configuration,
the air nozzle and the liquid nozzle being angled towards each other,
the deflection orifice being angled towards the liquid nozzle, thereby deflecting liquid residue from the liquid nozzle away from the air nozzle,
the air nozzle and the deflection orifice being in fluid communication with a single air manifold;
wherein the sensor system has a housing, the housing having:
a bottom plate for attachment to a surface of the SDC;
one or more walls connecting the bottom plate to a top plate, the surface of the sensor system being disposed inside the housing and facing outwardly towards the one or more walls; and
the top plate defining the air conduit, the liquid conduit, and the triangular configuration positioned on an edge of the top plate, the triangular configuration oriented to deliver the air jet and the liquid jet towards the surface of the sensor system placed vertically below the top plate.
