The paper presents a comparison of two methods of balancing a washing machine, oni with free balls and the other with liquid. For both of them the physical and mathematica models are presented. The distribution of clothes in the washing machine is random and i is not possible to predict the dynamic forces. It is shown that the use of liquid cannot givi good results because only a part of the washing machine can be counterbalanced. In the case of using ball balancers, the washer's vibration can be completely balanced. The reason that the balls or liquid change their positions with respect to the basket is shown.
