<p>The invention relates to a method and apparatus for cleaning textiles submersed in water by means of ultrasonic energy. To avoid the use of chemical additives normally used to improve the cleaning action, the water is subjected to a second movement, enhancing the cleaning action. This second movement may be a stirring movement, but preferably it is an ultrasonic movement as well. Then it is advantageous to have both ultrasonic movements act at the same time. The washing machine is suitable for domestic use.</p> |
