The study highlights the "evolutionary design" processes and the results of the product through an example of a device design on the target of surface cleaning at high buildings. In today's high buildings glass cleaning is carried out manually by the employees via ropes on the buildings. During this process, there are frequent situations in which employees are exposed to vital danger due to environmental wind speeds. To prevent this situation, a design study has been carried out in order that the developed surface cleaning device should be capable of surface cleaning at high wind speeds. The study was carried out in two stages. At first, the pressure forces on the surface of the device were determined according to the wind speeds and the friction coefficients were found. In the second stage, displacement and swing distances at different wind speeds of the device were investigated depending on the pressure forces applied to the device surface. The evolutionary design process was operated for the device with three different form structures and the design decisions were taken by calculating the aerodynamic improvements with ANSYS-Fluent program and displacement distances with ANSYSMechanical program for the model with low friction coefficients. It also tried to emphasize the process-related effects of the evolutionary design approach used alongside the technical output of the product.
