Abstract - Window cleaning makes the building's architectural glass free from dust and dirt. The traditional way of cleaning office windows cannot be applied to high rise windows with huge sections of glass. Cleaning the windows from outside requires special tools in going up and it's really unsafe. The Window cleaner proposed is an unmanned device which would be controlled by using a microcontroller. This device would be safer compared to traditional methods of window cleaning in case of high glass structures that increases risk in loss of human life. Structure of the proposed device consists of a triangular frame and uses suction cup based adhesion technique to adhere on the glass surface. The movement of the frame over the glass is done by using special rigging. The frame consists of an automated cleaner which is run by motors and pre-programmed microcontrollers. The automated cleaner moves in vertical direction within the frame using the threaded shaft.
