Robot window washers

The city of Dubai in the United Arab Emirates is equipped with robotic window washers. The advantages of robots from the Serbot AG company are numerous: worker safety (robots instead of humans), faster execution speed (150 m2 per hour for the machine instead of 20 to 30 for a man) and the option of working in windy conditions. The robot moves in several directions using suction cups and cables. Given the height of the skyscrapers in the city of Dubai, the work that these machines provide is a great idea. This type of extreme robot will increasingly replace humans in the future for obvious cost, speed, and safety reasons. Who can compete with it?
