This paper describes the design of a low cost miniature-cleaning robot CLEANtech equipped with navigation and obstacle detection sensor suite and powerful actuators to carry out dry and wet mopping in an enclosed environment. The present design is a modified wheeled mobile robot with added sensing and actuation blocks for carrying out the cleaning task within a specified work envelope. The advanced motion-planning algorithm enable this embedded robot to cover all possible paths to remove dirt and dust from the floor efficiently. Floor cleaning robots have found special attention during COVID-19 pandemic where healthcare providers have recommended special caretaking of body and environmental hygiene in order to successfully control the spread of the viral infection.
