PURPOSE: A movable polishing device is provided to enable a working head to be accurately set on a desired position since if the floor is not even, the slopes in four directions of a housing are controlled by a guide cylinder. CONSTITUTION: A movable polishing device comprises a housing(110), a plurality of working heads(120), a driving motor(130), a guide cylinder(140), and a folding cylinder(150). The housing is coupled to a moving unit(200) by a flexible joint(112). The working head is installed downwardly on the housing. The driving motor is coupled to the housing and operates the working head. The guide cylinder is vertically installed on the housing. The guide cylinder controls the height of the housing. The folding cylinder is coupled to the moving unit by a pin. The end of the rod(151) of the folding cylinder is coupled to the housing.
