<p>A water-extracting device comprising: a water extraction tank (200) for extracting water from clothes; sensor elements (152, 700) for outputting detected signals including information on vibrations of the water extraction tank (200); and a control device (150) for controlling the water extraction tank (200) on the basis of the detected signal. The water extraction device is characterized in that the sensor elements comprise a first sensor element (152) that detects the amplitude of the water extraction tank (200) in a first direction and a second sensor element (700) that is installed in a second direction with respect to the first sensor element (152), the second direction being opposite to the first direction.</p>
