I. Background and Industry Demand

With rapid urbanization, the cleaning and maintenance of high-rise façades, power plant cooling towers, and chemical facility exteriors have become urgent industrial needs.
Traditional “spider-man” manual rope access cleaning faces three major challenges:

· High safety risks: Personnel suspended at height, frequent accidents.

· Low cleaning efficiency: Limited coverage per operation, time-consuming process.

· Inconsistent cleaning quality: Manual operations make it difficult to maintain even pressure and full coverage.

The market urgently needs an innovative solution that enables mechanized high-altitude operation, standardized cleaning processes, and integrated workflow management.
The Kitefly Tethered Water-Supply Drone System was developed precisely to meet these needs.
