Stairs cleaning is time-consuming task and monotonous Stairs cleaning is time-consuming task and monotonous. As a result, most people tend neglect this task or focus on other areas of the house. Hiring professional cleaners for deep cleaning on monthly basis may be costly to some. Present vacuum cleaners, upright ones are not suitable ones. Those which can be made into portable ones or handheld ones are easier to maneuver but it still takes one’s time and effort to complete this task. How to clean efficiently? Problem Statements

Project Background & Overview Stairs cleaning robot is autonomous so cleaning is “done by itself”. It still requires a very minimum effort, however Robot will have to descent from top of the stairs. We’re attaching linear actuators/electric motors to achieve this Lightweight and medium The robot is able to clean stairs of any width effectively For motorized cleaner powered by gasoline to that by electric Research on Adjustable Chassis (mechanical movement) Project Background & Overview
