Drone Cleaning System: 24/7 Continuous High-Altitude Operation with
Tethered Power
Stop Battery Anxiety. Replace manual rope-access cleaning with
Kitefly’s industrial tethered cleaning solution.
Battery-powered drones are typically limited to 20–40 minutes of flight time, making them unsuitable for large-scale facade
cleaning projects. Our tethered drone cleaning system delivers continuous power supply from the ground, enabling
long-duration and stable operation for high-rise buildings. With up
to 16kW output power and 120m tether length, the system is designed for industrial cleaning tasks where
consistency, safety, and uptime matter. Proven in Lianyungang

Industry Pain Points
Fatal Flaws of Traditional High-Altitude Cleaning
· Severe Safety Risks: Rope-access “spider-men” cleaning exposes workers to persistent
fall hazards and high insurance pressure.
· Inefficient and Costly: Cleaning a supertall façade often requires large crews, long
schedules, and heavy labor cost.
· Operational Restrictions: Work is easily interrupted by weather, while curved glass, hollow
structures, and hazardous industrial zones are difficult to access
manually.
· Environmental and Social Disruptions: Scaffolding and rope-access operations affect traffic, site order,
and surrounding building use.
Limitations of Conventional Drone Cleaning
· Payload often below 10kg
· Flight time often below 20 minutes
· Water pressure often below 5MPa
These limitations make conventional drones insufficient for continuous commercial-scale cleaning operations.

FAQ
Q: What is a tethered drone cleaning system?
A: It is a high-altitude cleaning solution that supplies continuous
power from a ground tether station to an airborne power module,
helping the drone operate far beyond battery flight limits.
Q: How does it solve the endurance problem?
A: Instead of relying only on onboard batteries, the system uses a
ground power station and tether cable to deliver continuous power,
which is more suitable for long-duration façade cleaning.
Q: What cleaning height can the system support?
A: The AF-G30 manual lists a single tether length of 120 m, which
is the key reference for high-altitude operations in this
configuration.
Q: Which parameters do customers usually care about most?
A: For the ground system, customers usually focus on input power
requirement, output voltage, tether length, power output, and reel
control mode. For the airborne module, the main concerns are input
voltage range, rated output voltage/current, rated power,
efficiency, size, and protection functions.
Q: Why are the drone airframe parameters not listed here?
A: This page is positioned as a cleaning solution page rather than
a UAV export page. For export communication, it is usually more
useful to focus on the tether station and airborne power module,
which are the core parts of the cleaning power solution.
Q: Can this solution be adapted for different industrial scenarios?
A: Yes. It can be configured for façade cleaning, industrial
maintenance, and some specialized spraying or coating tasks
depending on payload and project requirements.
