This study aimed to determine the optimum washing of laboratory washing model that design to stimulate the active washing process and passive commercial washing machine are compared in order to determine the best washing result. Variables of the study include water speed, washing time and radial nozzle inclination angle. The rotational system of an automatic washing machine has two major technical difficulties. One is the collision of the tub against the frame at the beginning of its early spinning stage. A factor that causes such instability of the rotational object can be attributed to the deflection of the liquid inside the liquid balancer due to the unbalance mass. Proposed a new washing technology and new design of the washing machine can be as a base of its new type. These machines have better outcome data; improve quality of washing process and effective use of washing liquid. New washing machine is simple design, does not have rotary parts at all and uses active process of washing process with squeezing of linens and more productive then known washing machines. Also, this machine can recycle and feed cleaned washing liquid. Additionally, in use of ultrasonic technology of washing process, new machine today will be perfect design.
