Recently, the Nanjing Feiying FC30 tethered drone for curtain wall cleaning was successfully delivered. At a commercial office construction site, the drone—equipped with a high-pressure cleaning module—precisely hovered above the glass curtain wall. Fine jets of water evenly washed along the curtain wall’s textured surface, completing in just 30 minutes what would normally take a traditional “Spider-Man” half a day to accomplish. This milestone marks the official entry of the high-altitude cleaning industry into the “tethered intelligent era.”
As equipment specially designed for high-rise buildings, the FC30’s 120-meter tethered system achieves a dual breakthrough: On one hand, by relying on continuous power supply from the ground, it overcomes the limitations of battery life, enabling each unit to operate continuously for 8 to 10 hours. On the other hand, it employs high-strength, wear-resistant cables that can withstand a 30-kilogram payload while resisting strong winds up to 12 meters per second. Even in wind conditions as high as Force 6, the drone can maintain stable hovering, thereby solving the longstanding challenge of traditional drones’ “swinging tail” phenomenon at high altitudes.
Tech-Heavy: Customized Solutions Tackle Industry Pain Points
The delivery of FC30 is not just a single product implementation, but rather a customized solution tailored for curtain wall cleaning scenarios.
1. Customization capabilities for full-scenario adaptation
Material compatibility: For curtain wall materials such as glass, stone, and aluminum panels, customize the high-pressure nozzle pressure (adjustable from 30 to 80 bar) and the detergent ratio to prevent damage to the materials.
Structural adaptation: Equipped with an adaptive balancing system, it uses binocular vision and phased-array radar to scan the building’s 3D model, automatically adjusting the cleaning angle for curved and uneven facades to eliminate cleaning blind spots.
2. Build a safety redundancy protection network.
The dual tether backup system ensures zero risk of falling from a height of 120 meters. Key components meet the IP68 waterproof rating, allowing normal operation even in light rain.
The phased-array radar with a 3-meter detection range performs real-time scanning of obstacles, and its accuracy in identifying reflective materials such as glass is three times higher than that of traditional vision-based obstacle-avoidance systems.
3. A Double Leap in Efficiency and Environmental Protection
Data shows that the FC30 single-unit machine can cover an area of 8,000 to 10,000 square meters per day—6 to 20 times the coverage of traditional manual cleaning. In the Taizhou Talent Building project, just two FC30 units completed the cleaning of a 10,000-square-meter curtain wall in only 18 hours. Meanwhile, the precision spray system reduces water consumption by 60%, and when paired with eco-friendly cleaning agents, it achieves “zero pollution” operations.
Industry Transformation: From “High-Altitude Adventure” to “Smart Operations and Maintenance”
The delivery of the FC30 is reshaping the high-altitude cleaning industry. In the past, “Spider-Man” operations not only faced the risk of falls but were also confined to a narrow operational window—limited to winds below Level 4 and temperatures ranging from 0°C to 35°C. However, thanks to its operating temperature range of -20°C to 45°C and an IP55 protection rating, the FC30 can extend the number of effective working days throughout the year by up to 40%.
The deeper value lies in labor substitution. As the “Spider-Man” workforce continues to age, the industry is facing a labor shortage. Each FC30 unit can replace 3 to 5 human workers, and remote ground-based control further reduces personnel training costs.
Future Outlook: Mooring Technology Opens Up New Opportunities in the Low-Altitude Economy
This delivery of the FC30 is just a microcosm of tethered drone applications. From being an “aerial lighthouse” for power grid emergency repairs to serving as an “intelligent butler” for curtain wall cleaning, tethered technology—with its advantages such as 24-hour station-keeping and heavy payload capacity—is opening up new frontiers in the low-altitude economy. Meanwhile, by integrating digital twin technology to enable multi-drone collaborative operations, this approach is further driving the intelligent upgrade of high-altitude operations and maintenance.
As the 120-meter tether connects the ground to the sky, the FC30 is not only cleaning the “face” of buildings but also erasing the marks of transformation in traditional industries—high-altitude work is bidding farewell to the “age of risk” and stepping into a new era characterized by “safety, efficiency, green practices, and smart technology.”
