The High-Altitude Facade Cleaning Spray Lance Kit (Dual-Nozzle) is a dedicated facade cleaning payload purpose-built for the DJI M400 enterprise UAV. Featuring a lightweight carbon fiber extended-lance design, the entire unit weighs just 1.15 kg and mounts securely under the fuselage via bolt fixation. Compatible with the DJI M400 E-Port V interface, it connects directly to DJI Pilot 2 for control through the PSDK protocol. Equipped with a dual-nozzle system, the kit supports one-touch switching between high-pressure water jet and foam cleaning modes, delivering a spray distance of 7–10 meters. The integrated cross-oscillation mechanism enables a ±30° lateral sweep, effectively covering facades of varying orientations. With a recommended flight altitude of ≤120 m and a 20 MPa high-pressure water hose rated for aerial cleaning demands, the system is widely suited for high-altitude operations including glass curtain wall cleaning, exterior wall tile cleaning, and billboard cleaning. It delivers a safe, efficient UAV-based cleaning solution for high-rise building exterior maintenance.
