Abstract

Aspects of the disclosure relate to cleaning rotating sensors having a sensor housing with a sensor input surface. For instance, a first signal indicating that there is a contaminant on the sensor input surface may be received. In response to receiving the first signal, a second signal may be sent in order to cause one or more transducers to generate waves in order to attempt to remove the contaminant from the sensor input surface.
