Business idea - an automatic window cleaning robot

My business idea is related to creating an automatic window cleaning robot. At the beginning, how important it is for me that the product is cheap and available on the market in Europe, and above all that it is made of quality material, so that my company and I can offer consumers a guarantee and security. My idea is for the robot to be fully automated because we live in an increasingly modern society where with just one click on the mobile we can clean the house or let the air conditioner work while we are not at home or open the curtains on the windows of the house. I think that there is no such product on the market yet, so my idea will be an inspiration for many companies in the future. The purpose of this robot machine is to be glued on both sides of the window, which would clean both sides with one movement, thus saving energy and money. Bigger and bigger buildings are being built where man needs special equipment which is very expensive to be able to clean a 100-storey building. The uniqueness of this product is that we should not use force or bother to clean, but all this will be available to us with just one click on the mobile phones
