b. a robotic arm to grasp and move said article;
c. a camera to acquire an image of said article;
d. a processor configured to:
i. execute a cleaning protocol based on said image, wherein said cleaning protocol lists a time sequence of a plurality of robot positions such that said spray makes contact with all regions of said article;
ii. execute a targeted cleaning protocol based on said image, wherein said targeted cleaning protocol lists a time sequence of a plurality of robot positions such that said spray makes more contact with soiled regions of said article relative to clean regions of said article; and
