Problems Specification: The number of glass buildings in Palestine and the neighboring countries is increasing, these buildings owners use the traditional method in cleaning windows. The traditional method is through employing a number of workers that manually cleaning windows, which is considered to be an inefficient, costly and relatively slow as the cleaning process takes a long time. This method could also be harmful to the workers which make it dangerous, heavy task for employees and creates very stressful situations for them, which might cause death and financial loss.

Solution: Sky Cleaner Machine will save time, money, and also will save workers lives. This method cleans windows and glasses faster than hand method. The machine will keep moving on the surface of the glass doing four operations (brushing, sprinkling water , wiping and moving up and down at the same time) ,while the hand method will do one operation at a time. Mechanical method requires less number of workers, thus, less labour cost . The Window cleaner proposed project 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 the risk of losing human lives.

Constrains and Standards: -The Sky Cleaner machine will consist of two parts: Part one : Vehicle. -Frame -LCD Screen -Microcontroller -Electrical Motors -Wheels -Cables and pulley This part will move in one axis ( parallel to the edge of the top of the building ), using orders of the remote control which will actuate the motor to move forward and reverse.

Part Two: Box. Frame. Electrical Motor. Brush. Wiper. Pump. Wheels. In this part, the liquid(water & cleaning fluid) will be sprinkled on the window using nozzles, and the brush will clean the dust, finally, wipers will wipe the window. Knowing that this part will be dangled by the cables moving up and down.

Advantages: - 70-80% labor savings. - Reduced insurance premiums Advantages: - 70-80% labor savings. - Reduced insurance premiums. - Safely operated from roof top or ground. - Cleans windows, frames and building exteriors. - Fast return on investment (ROI).

Conclusion : Through our project, we decided to develop the idea of cleaning the glass by machine and to achieve our goals which we work for it by raising the level of safety and reduce costs and a better quality has faced several problems: The first problem is how to move the cleaning machine horizontally or vertically The second problem we faced that the power of the motor that should operate the process. Thirdly, the number of motors needed in our project to operate the process and achieve the minimum level of safety.
