'Clean Assist' Function
The optional Clean Assist function is designed to facilitate high-pressure cleaning operations, offering precise and safe control.
Using a hyperfrequency radar installed directly on the spray nozzle, this system detects obstacles in front of the drone.
It acts as a frontal anti-collision system, enabling the drone to maintain a safe distance from the surfaces to be cleaned, which can be adjusted via the remote controller.


The remote control enables you to manage the hose length from a distance, ensuring precise control and hassle-free maneuvering of the drone during cleaning tasks. This advanced feature not only saves time but also enhances safety by reducing the risk of tangling or accidents.
