1. A method for cleaning a rotating sensor, the sensor including a sensor housing with a sensor input surface, the method comprising:
receiving, by one or more processors of a controller, a first signal indicating that there is a contaminant on the sensor input surface; and
in response to receiving the first signal, sending, by the one or more processors of a controller, a second signal to one or more transducers in order to cause the one or more transducers to generate waves in order to attempt to remove the contaminant from the sensor input surface, wherein the first signal further indicates a type of the contaminant and wherein the one or more processors responsively control a ratio of standing waves to traveling waves generated by the one or more transducers based, on the indicated type of contaminant.
