KTV Working Drone originated from an idea to find an innovative and efficient way to clean facades and windows. This was back in 2015. A lot of mods were needed to make the drone work properly for cleaning, also commercial. Fast forward the result is a unique drone with tailor-made and uniquely adapted mounting equipment with specially designed cleaning equipment. A patent pending safety solution to prevent the drone from falling down during operation is also developed. The drone has been extensively tested and commercialized for window and facade cleaning, and has been used operationally since 2020 by the KTV Group in Norway. In 2022, KTV Working Drone was ready and the commercialising process started. Today KTV Working Drone is established almost all over the world, and the partner network is growing rapidly.
