A laundry treating apparatus (10) comprising a tub (30), a drum (50) rotatably mounted inside the tub (30), at least one ball balancer (500) mounted centred to the drum (50) having an annular channel defined therein, at least one ball (400) movably disposed in the said channel, said ball being free to move in the said channel under the action of gravitational and inertial forces, characterized in that at least one actuator element (200, 1200) is fixed to one side of said balancer (500), said actuator element (200, 1200) has at least two controlled states to enable, block or constraint the transit of said ball (400) at its position, said actuator element (200) by dynamically enabling respectively blocking or constraining the ball (400) transit in the said balancer (500) channel at its position can act on the ball (400) position in the balancer (500), so that the unbalance (90) in the drum (50) is offset by at least the one ball mass (400).
