The invention provides a shoe-washing machine. The shoe-washing machine comprises a water-containing barrel, as well as an inner impeller and an outer impeller which are arranged inside the water-containing barrel, wherein the inner impeller is fixedly arranged in the central position of the bottom of the water-containing barrel, and the outer impeller is rotatably arranged on the periphery of the inner impeller; a central hairbrush is arranged on the inner impeller, and a barrel wall hairbrush is arranged on the inner wall of the water-containing barrel. According to the shoe-washing machine, two impellers, namely, the inner impeller and the outer impeller are arranged inside the water-containing barrel, the inner impeller is fixedly arranged in the central position of the bottom of the water-containing barrel, the outer impeller is rotatably arranged on the periphery of the inner impeller, the central hairbrush is arranged on the inner impeller, and the barrel wall hairbrush is arranged on the inner wall of the water-containing barrel. In the washing state, the outer impeller rotates to drive shoes to move, in the moving process of the shoes, the shoes have contact friction with the fixed central hairbrush so as to be washed, and meanwhile, the barrel wall hairbrush can rub the other sides of the shoes, so that the washing effect is further improved.
