The subject disclosure relates to features that facilitate the automatic cleaning of optical sensors and in particular Light Detection and Ranging (LiDAR) sensors used in autonomous vehicle deployments. In some aspects, the disclosed technology includes a sensor cleaning apparatus having a housing, wherein the housing is configured to be rotatably coupled to an optical sensor, a wiper blade coupled to the housing, wherein the wiper blade is disposed at a downward angle relative to a top-surface of the optical sensor, and one or more nozzles disposed within the wiper blade, wherein the nozzles are configured to apply compressed gas to a surface of the optical sensor.

A surface wiper device which includes a carrier which supports a blade. The carrier attaches to a wiper arm which urges the blade against and moves the blade across the surface of a windshield. The carrier further provides a plurality of outlets each of which communicate between a hollow passage inside the carrier and a location on the external surface of the carrier. A fluid can be delivered from a fluid source fluidicly coupled to the hollow passage of the carrier under sufficient pressure to be dispersed from the plurality of outlets onto the windshield during movement of the blade. A fluid heater can be thermally coupled with the fluid delivered from the fluid source to the plurality of outlets to increase the temperature of the fluid dispersed onto the windshield. The fluid can be sufficiently heated to generate a heated gas.
