A self-cleaning entry rug assembly has a housing with a hingedly supported top plate extending over substantially its entire top and providing transversely extending openings adjacent its opposite ends. A frame is supported on the top plate and rotatably supports a pair of tread rollers extending in the transversely extending openings of the top plate as well as auxiliary rollers. An endless belt carrying a rug extends about the tread rollers and auxiliary rollers, and a rug cleaning device is provided in the housing below the closed path. One of the auxiliary rollers may be moved on the frame to vary the tension on the belt, and a drive motor effects rotation of the rollers to rotate the belt and rug. A control system controls the drive motor and cleaning device, and it is adapted to receive a signal from a presence sensor adjacent the entry rug assembly to terminate rotation of the rollers upon approach of a person.
