PROBLEM TO BE SOLVED: To provide an autonomous cleaning device capable of optimizing the cleaning capacity and efficiency of a cleaning mechanism. SOLUTION: The autonomous cleaning robot includes a chassis, a driving system mounted to the chassis to move the autonomous cleaning robot, and a cleaning head mounted to the chassis to clean a floor surface. The cleaning head includes a deck mounted to the chassis so as to be vertically pivotable with respect to the floor surface; a brush assembly mounted to the deck; and a deck adjusting assembly for pivoting the deck according to the torque change of the brush assembly. The deck adjusting assembly includes a pulley mounted to the deck side, and a pulley cord with one end fixed to the chassis side and with the other end fixed to the pulley.
