To clean the 75,000 windows with a total area of approx.400,000 m2 of glass, three horizontal rails will be available on the building, each of which will have a bucket machine with a weight of 5,000 kg. The top of the building is cleaned by industrial climbers who use ropes to descend from the top and do their work.

Under normal conditions, when all building maintenance units are in operation, 100 employees need three to four months to clean the entire outer building.

Inventor Mehmet Tuzcu develops unmanned machines that clean glass levels and the glass helmet.
