What Are the Brushes on Escalators Actually For?

Those brushes along the sides of escalators are not there to clean your shoes. They are skirt deflectors designed to help keep feet, footwear, and loose clothing away from the narrow boundary between a moving step and a stationary side panel. This video explains how that boundary creates risk, why a few centimeters of separation matter, how brush deflectors change foot placement, and what they can—and cannot—protect you from.
