Abstract
A sensor-cleaning system includes a sensor of a vehicle, an electrode, and a computer communicatively coupled to the electrode. The sensor includes a lens. The electrode is positioned to draw dust from the lens when the electrode is energized. The computer is programmed to energize the electrode in response to the vehicle moving and deenergize the electrode in response to the vehicle being stationary.
