Abstract: Aspects of the disclosure relate to cleaning rotating sensors having a sensor housing with a sensor input surface. For instance, a first signal from a position sensor indicating a current position of the sensor housing may be received. A second signal to activate a liquid nozzle and an air nozzle, the liquid nozzle being configured to provide a spray of liquid and the air nozzle being configured to provide a puff of gas may be received. When to activate the liquid nozzle in order to provide the spray of liquid on the sensor input surface may be determined based on the current position of the sensor housing and the second signal. When to activate the air nozzle in order to provide the puff of gas on the sensor input surface may be determined based on the current position of the sensor housing and the second signal.
