U.S. Products’ TreadMaster self-contained, compact escalator cleaning systems are designed to effortlessly clean and polish escalator stairs. Position the TreadMaster at the bottom of the escalator and lower the cleaning head into position then simply activate the escalator. The system’s built-in vacuum collects surface-level dirt and debris as the escalator moves. Brushes automatically remove dirt and soil embedded in the treads of the steps. Pads then polish the steps. The system essentially works by itself without any repositioning. Use it to thoroughly clean any tread width.
