Abstract: A system for inspecting wearable people footwear, comprising: a person's standing grille, an air stream chamber, whereas the grille is one of the partitions of the chamber, a plurality of blowing jets surrounding the object and a vacuum port. While said object is being under normal atmospheric conditions, the particles are being detached from the object exterior surface by said plurality of blowing jets detached particles are passing through said grille holes and are carried by near surface airfoil streams generated within the chamber and directed towards the vacuum port. An analyzer instrument analyzes the particles, collected at the particle collection area.
