The invention provides a roller washing machine. The roller washing machine comprises a box, an outer barrel, an inner barrel, an ordinary inlet system and a strong water flow inlet system, wherein the strong water flow inlet system comprises: a second inlet pipe, a second inlet valve and a nozzle, the first end of the second inlet pipe is connected with the nozzle, and the second end of the second inlet pipe is connected with the inlet, and the second inlet valve is arranged on the second inlet pipe, which is used to control the open and close of the second inlet pipe, the nozzle is installedin the box, and the injection orifice of the nozzle directs toward inside the barrel mouth of the inner barrel. The scheme uses the strong water flow formed by the water pressure of tap water to washclothes in the washing earlier and middle period and cause the surface stain to dissolve, so as to enhance the cleaning effect. Compared with the circulatory system in the existing technology, the technology does not need pumping, the system structure is simpler, the cost is lower, and the flow intensity of washing clothes is large, and the cleaning effect is good.
