Claim 0:
1. A mat cleaning device which washes and dries a mat, the device comprising:
a casing which constitutes an exterior of the mat cleaning device;
a washing water spray nozzle which is disposed on one side of the casing and configured to spray a washing water on the mat;
a drive motor which is disposed inside the casing;
a plurality of rollers which are rotated by the drive motor and configured to transfer and wash the mat;
a vacuum pump which is configured to form a vacuum pressure;
a vacuum suction which is configured to suck moisture and foreign matter on a surface of the mat by using the vacuum pressure formed by the vacuum pump;
a centrifugation chamber which is configured to provide the vacuum pressure formed by the vacuum pump to the vacuum suction and centrifuge the moisture and the foreign matter sucked by the vacuum suction; and
a hot air supplier which has a first end coupled with a discharge hole of the vacuum pump and has a second end disposed under the mat so as to dry the mat by using air discharged from the vacuum pump,
wherein the vacuum suction comprises:
a vacuum chamber which is connected to the centrifugation chamber and configured to provide suction force thereto; and
a bottleneck which is formed on an upper part of the vacuum chamber, wherein the bottleneck is smaller in a width than the vacuum chamber, and a plurality of vacuum suction slots are formed in an upper surface of the bottleneck,

wherein the plurality of rollers comprises:
a guide roller which is configured to rearwardly transfer the mat, said guide roller being rotated by the drive motor; and
a first pressing roller which is disposed at a rear side of an upper part of the guide roller and configured to press the mat transferred by the guide roller to an upper part of the bottleneck while the first pressing roller is in contact with the guide roller,

wherein friction members are attached on a surface of the first pressing roller,
wherein the friction members are attached on the first pressing roller by being spaced at predetermined intervals apart from each other in a longitudinal direction of the first pressing roller, and
wherein a material of the friction members is a non-slip tape, and the surface of the first pressing roller has a predetermined smoothness level.
