A surface traveling mobile apparatus which moves by an endless track belt installed to be wrapped around a case from end to end, traveling on a surface by the rotation of wheels driven by a power source is provided. The surface traveling mobile apparatus includes vacuum chambers installed to be attached to the sides of the wheels, a vacuum tube for connecting the vacuum chambers to each other, a vacuum pump formed in part of the vacuum tube, the vacuum pump for inhaling and exhausting air, and suction mechanisms installed along the endless track belt at predetermined intervals, valve driven by contacting the wheels, and vacuum attached to the surface by the vacuum pump inhaling and exhausting air. Also, a cleaning apparatus including a spray unit for spraying water or wash liquid to the surface when the surface traveling mobile apparatus moves, and a rotating brush for washing the surface using the sprayed liquid, are provided. Accordingly, the surface traveling apparatus and the cleaning apparatus using the same can freely travel a plane, an inclined plane, a vertical plane, and a ceiling and thus, can clean areas which are not easily cleaned by people, such as windows or high buildings and high ceilings.
