Why This Project Matters High-rise glass curtain wall cleaning has long relied on rope-suspended workers - a method that is slow, expensive, and inherently dangerous. When Guizhou Transportation Group needed a safer and more efficient maintenance method, it adopted Kitefly Tethered's dual-tethered drone cleaning system: a complete solution integrating continuous ground power, high-pressure water delivery, and industrial aerial cleaning deployment. The system completed full operational testing and formal acceptance review, and all core performance indicators exceeded the original specification. What Is a Dual-Tethered Cleaning System? Traditional cleaning drones may carry a spray nozzle, but battery endurance and water pressure at altitude quickly become limiting factors. Kitefly Tethered addresses both issues at the same time through a dual-tether architecture: Power tether - continuous 380V ground power feeds the drone and onboard systems without battery-duration limits. Water tether - high-pressure water is delivered from the ground pump to the airborne spray lance, maintaining stable pressure at working height. The result is a system capable of 24+ hours of continuous operation, spray pressure up to 20 MPa, and cleaning efficiency of 800-1,000 m² per hour, while keeping all personnel on the ground. System Configuration This deployment integrates four core components from Kitefly Tethered's product line together with the DJI FC100 heavy-lift aerial platform. Ground Power Unit - G40Pro Tethered Power Box The G40Pro converts standard 380V three-phase grid power into regulated high-voltage DC output for the drone and all airborne systems. Key Parameter Specification Input Power 380V AC (3-phase, 4-wire) Output Voltage 0-1000V DC (adjustable) Rated Output Power =97% Protection Rating IP65 (partial components IP67) Operating Temperature -26°C to +40°C Storage Temperature -40°C to +65°C Altitude Rating 0-3,000 m Weight =95% restored Personnel working at height Zero Continuous operation (no fault) Full-duration test passed Compliance with safety standards Full pass Operational Advantages Unlimited endurance. Grid-connected ground power eliminates battery swapping and return-to-home interruptions. The system can support 24+ hours of continuous operation, making it suitable for full-facade cleaning tasks. No workers at height. All personnel remain on the ground and operate the system remotely, removing rather than merely reducing fall risk. Stable pressure at altitude. The ground pump delivers sustained high-pressure water to the airborne spray lance, while the integrated tether arrangement helps maintain continuous cleaning performance. Access to complex geometry. The telescopic AF-Q2 lance improves reach for recessed joints, curved curtain wall sections, and other hard-to-clean areas. Cleaner and greener operation. No fuel combustion is required during operation, and the process is compatible with green construction and maintenance requirements. Application Scenarios This system is intended for large-scale facade cleaning and infrastructure maintenance projects where conventional manual methods are unsafe, slow, or operationally impractical. Super high-rise office towers and commercial complexes Transportation hub terminals and stations Large-span glass atrium structures Bridge cable cleaning and surface maintenance Tunnel interior wall cleaning Industrial facility exterior maintenance About Kitefly Tethered Kitefly Tethered develops and manufactures tethered power systems for industrial drone operations.
