A system includes a sensor window, a sensor having a field of view through the sensor window, a piezoelectric vibrator positioned to impart vibrations to the sensor window, and a computer communicatively coupled to the sensor and the piezoelectric vibrator. The computer is programmed to identify a type for an obstruction of the sensor window based on data from the sensor, and instruct the piezoelectric vibrator to vibrate the sensor window with vibrations having a vibration profile. The vibration profile has at least one of frequency or phase velocity chosen according to the identified type of obstruction.
