This week KTV Group carried out window cleaning at Bergen Airport Flesland using KTV Working Drone technology. The operation is considered one of the most demanding cleaning tasks within this type of work in the world.

The entire project had to be completed within a three hour night window, during which a total of 2,500 square meters of glass façade had to be cleaned. The working conditions were challenging. The terminal area acts as a wind tunnel, while the metal structures in the roof create significant limitations for GPS signals. In addition, signal interference is common in the area, making the operation technically demanding.

To handle these conditions, the new DJI M400 was used together with sensors and software developed by KTV Working Drone. The operation was completed with high precision and without technical issues.

The glass surfaces at Bergen Airport also represent a significant cleaning challenge. Pollution levels are very high, and previously even manual cleaning with rope access technicians has taken several weeks without achieving the desired result.

Through continuous development of new cleaning methods, KTV Working Drone has developed techniques capable of handling extremely demanding cleaning conditions. For this project, the new chemistry KTV Window Facade+ was used with excellent results.

An important milestone is that even heavily contaminated windows, which previously could not be cleaned effectively using drone technology, can now be cleaned with very good results.

Another important advantage is that the method does not involve mechanical contact with the glass. This eliminates the risk of wear and damage to the windows, which can often occur during traditional manual cleaning.

Conclusion.
The experience from this project confirms that the technology is now mature enough to operate in some of the most demanding environments and cleaning operations within this type of work.

Looking back at where the technology was in 2020 with the first generation systems and comparing it to the level we have reached in 2026, the development has been enormous.
