The floor mat is formed from an array of interlocking tiles. Each tile is based on an open matrix structure which defines in its upper surface rows of recesses (8) for receiving carpet strips interleaved with rows of scraper elements 32. The carpet strips are anchored in the recesses with the aid of nipples (18) which engage apertures in the carpet strip backing and by peripheral retaining projections (12). The scraper elements (32) may be positioned within a cavity and protrude above the surface of the matrix structure and scrape and agitate the scrapings down the cavity in which they are located. An array of probes (46) agitate the underside of the carpet strips and double action male and female connectors (4,6) enable adjacent tiles to be securely locked together irrespective of which way up the tiles are placed next to each other. |
