An apparatus for automatically cleaning dirt and debris from a pedestrian's footwear. The apparatus can be an integral portion of the entryway door's threshold or else can be made portable. The pedestrian steps upon a removable tray and activates a vacuum source. The vacuum source pulls the dirt and debris from the pedestrian's footwear through a multitude of openings in the removable tray. The dirt and debris is captured within the tray (large particles) and debris collection container (smaller particles) for later disposal. The apparatus cleans the welts and also provides a means for drying wet footwear. The apparatus can be either AC or DC powered and can be automated to only operate when a pedestrian is standing upon the tray, can operate continuously, or can be manually switched on and off.
