An apparatus comprises: a sensor window 70; a deflector 76 fixedly positioned to deflect a first airflow F1 travelling in an opposing direction to a direction of travel of the sensor window to one or more directions tangential to the sensor window, and a nozzle 106 fixedly positioned to direct a second airflow F2 through the nozzle to a space between the sensor window and the deflector. In a further embodiment, an apparatus comprises: a sensor window 70 defining a direction of travel; a wedge 76 spaced from the sensor window and positioned in the direction of travel from and one of above and below the sensor window, the wedge including an outer surface facing the direction of travel and an inner surface opposite the direction of travel; and a nozzle 106 aimed at the inner surface. A filter and compressor may be fluidly connected to the nozzle. The nozzle may be an air nozzle, further comprising a liquid nozzle fixed relative to the sensor window and positioned to eject liquid into the second airflow. The deflector may further comprise a second deflector positioned to deflect a third airflow.
