A lens-cleaning assembly includes an ultrasonic cleaning system configured to selectively generate vibrations in a lens. The ultrasonic cleaning system is operable to selectively generate cleaning vibrations at a plurality of pulse widths. The cleaning system also includes a controller in communication with the ultrasonic cleaning system. The controller is configured to automatically determine a target pulse width among the plurality of pulse widths in response to a detected characteristic of a detected occlusion on the lens, and to automatically control the ultrasonic cleaning system to generate a cleaning vibration having the target pulse width.
