1. An automated cleaning system, comprising:
a first illumination source for emitting radiation at a first wavelength in the short wave infrared range (SWIR) towards a field of view (FOV);
a receiver operating in the SWIR to acquire SWIR image data based on radiation reflected from elements located in the FOV; and
a processor for determining, based on the SWIR image data, presence of water-based liquids in the FOV, wherein the receiver comprises one or more germanium (Ge) photodiodes (PDs).
