A self-contained floor mat assembly that comprises a tray with a flow-through mat insert positioned thereon. The tray has an upper surface and a lower surface and the lower surface rests on the floor. The flow-through mat insert is positioned on the upper surface of the tray and the insert includes at least one hole that extends from the upper surface thereof through to a lower surface thereof. When people walk across the mat, liquid and particulate matter is scraped from their shoes and drops through the holes in the insert and onto the upper surface of the tray. If the insert is not secured to the tray, it may be periodically removed from the tray for cleaning purposes. The self-contained mat assembly can be moved and positioned anywhere on the floor surface as desired.
