PROBLEM TO BE SOLVED: To provide a position adjusting mechanism of dust suction device in a floor surface cleaning robot that the height adjustment of dust suction device is easily done and that results in great reduction of burden on worker. SOLUTION: A supporting axis 44 supports a spare wheel 42 rotatably. A guide member 45 enables the supporting axis 44 to move freely up and down, and the supporting axis 44 is energized upward with a spring 47. On the other hand, an eccentric cam 54, which is placed on a rotatory axis 53. A retaining tool 58 capable of being connected to a hook hole, which is formed in a supporting member 51, is provided on the arm 57. An eccentric cam 42 placed on the rotatory axis 53 rotates with the rotation of the arm 57, and the spare wheel 42 moves, following the rotation of the eccentric cam 42. Thus, the height between the floor surface and a dust suction device 30 is adjusted.
