Facades and high windows cleaned without scaffolding, cherry picker or ropes.
The cleaning drone hovers in front of the facade. A spray nozzle rinses off dirt, dust and rain streaks. The water comes through a hose from our van. It is purified, so it dries without marks. The pilot stands on the ground and follows every part of the facade on screen. That way the drone also reaches places a water-fed pole or cherry picker cannot.
