Abstract
Certain exemplary aspects of the present disclosure are directed towards apparatuses and methods which autonomously decontaminate parts. Parts to be cleaned are identified, and based on the identification of the part, a part specific cleaning program is initiated. During the cleaning, the part is manipulated about a gas supply in such a way that the drag force on the contamination particles attached to the part exceeds the contamination particles' surface adhesion force and accordingly is removed from the surface of the part. The removed contamination is then evacuated from the atmospheric environment near the part by a low pressure zone of a second gaseous material near the part.
