A milking robot comprises a robotic arm, a camera coupled to the robotic arm, a camera-facing nozzle coupled to the robotic arm, and a controller. The robotic arm extends in a longitudinal direction between the hind legs and from the rear of a dairy livestock located in a milking stall. The camera-facing nozzle sprays a protective layer of the camera with a cleanser. The controller communicates a signal instructing the camera-facing nozzle to spray the camera with cleanser.
