<p>A floor mat apparatus comprises a length (6) of plastics having a high plasticiser content, and therefore having a tacky surface to collect dirt and bacteria, trained about rollers (3,4) one of which is driven by a motor (4a) to bring fresh portions of the mat (6) to the upper stretch between rollers (3,4) across which people walk to a clean-room area. Portions of the mat leaving the upper stretch are washed at (7,8) and dried at (9) before returning to the upper stretch.</p> |
