The invention discloses an automatic cleaning method and device for movable escalator steps. The automatic cleaning method includes the steps that static images of the escalator steps are obtained through an imaging unit and transmitted to a control unit; the control unit compares the static images with pre-stored standard images to judge the pollution grades of the escalator steps and then determine the cleaning intensity in a spraying unit; and based on the cleaning intensity, the escalator steps are cleaned through the spraying unit. By means of the automatic cleaning method and device, the escalator steps can be cleaned in place, the cleaning efficiency is greatly improved, the water consumption of escalator step cleaning is reduced, and negative influences of drained waste water on the environment are avoided.
