2. 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

3. 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)
