The invention belongs to the technical field of washing equipment, and particularly relates to a shoe washing machine. The invention aims to solve the problems that during arrangement of a brush of anexisting shoe washing machine, the brushing area and the structural complexity of a transmission system are difficult to coordinate, and the surface of a shoe has a brushing dead corner. For the purpose, the shoe washing machine is provided with a rotatable brush component, and the brush component is capable of brushing shoes in a circumferential direction of the shoes. As for the washing effect,a mode of brushing the shoes in the circumferential direction enables the surfaces of the shoes to be free of brushing dead corners, and the omnibearing brushing ensures that the surfaces of the shoes are thoroughly brushed without missing parts. In terms of the number of brush components, the rotation arrangement of the single brush greatly reduces the transmission difficulty, the power system of the shoe washing machine is simple in structure and short in transmission chain, rapid installation and maintenance are facilitated, the possibility of failure is low, and the working stability of the shoe washing machine is good.
