A floor covering such as a nap mat or carpet of washable type comprises a rubber or plastic back, wherein the nap or tufts is/are fastened in the back material. The floor covering has means for increasing the drain of liquid from the nap when the floor covering is subjected to the influence of a force, such as a pressing force, a centrifugal force, and/or a pressure difference between the front and rear side of the floor covering. This means may be a normally closed perforation of the back material and/or an intermediate tissue via which the nap is secured to the back material. Preferably the intermediate tissue is a non-woven material, mainly consisting of synthetic fibres having a weight of 100-300, preferably 250 g per m2, a fibre thickness of 5-30, preferably 8 decitex, and a tissue thickness of 1-5, preferably 2 mm. Thereby a nap mat or carpet is achieved having a short drying time and/or provides a small drying energy consumption after washing.
