In a floor-surface polisher in which floor-surface is polished by a pad which is mounted within a pad cover and rotated at a high speed by a motor during the traveling operation of the polisher, a floor-surface polisher equipped with a function for adjusting a pad pressure being characterized in that the pad is resiliently supported by a support force, the support force directing upwardly to separate the pad away from the floor-surface, a plurality of very small spaces being formed within the pad so that a drawing force for lowering the pad toward the floor-surface against the upwardly-directing support force will be generated during a high speed rotation of the pad, electric-current value setter for adjusting, either automatically or manually, an electric-current value of the motor to a pre-set value, the setter being mounted on a control portion of the pad motor.
