An escalator handrail washing device according to one embodiment of the present invention comprises: a case that accommodates an escalator handrail and a washing unit; a self-generation unit, arranged in the case, for converting kinetic energy of the escalator handrail into electric energy; and a communication unit for transferring information on an operating state of the escalator handrail to a control center. The washing unit includes a plurality of rollers. At least one roller is rotated without power, by frictional force generated by contacting a surface of the escalator handrail, in a first direction which is a reverse direction of a preset rotating direction of the escalator handrail. Other rollers are rotated by rotational force of the at least one roller. The other rollers can sterilize or wash the escalator handrail while rotating.
