Who we are

Built in Hangzhou. Designed for real industrial environments.

Yun Yi Intelligent is a technology innovation enterprise based in Zhejiang, China, with a strong focus on tethered UAV applications. From Hangzhou, we serve customers with a system-led approach to high-altitude industrial cleaning.

Our core direction centers on glass curtain-wall cleaning and photovoltaic cleaning, integrating flagship UAV platforms including DJI M400 and T100 with cleaning payloads, tethered water supply, controls, and field operating methods.

OUR PRINCIPLE Start from the surface and site conditions, then engineer the aircraft, cleaning hardware, supply system, and operating process as one complete solution.

Our development path

The “dual-tether cleaning” concept.

In 2023, Yun Yi introduced the concept of dual-tether cleaning. The approach was developed around the practical needs of UAV cleaning customers and the realities of long-duration high-altitude work.

01

Water-tether system

A high-value spray solution designed for customers already operating their own UAV platforms.

02

Facade-focused deployment

Developed for glass curtain walls and complex building exteriors where traditional rope-access work is slow, labor-intensive, and difficult to scale.

03

Integrated field operation

Highly integrated equipment and controls make one-person, one-UAV deployment possible for suitable operating environments.

What defines our system

Integrated around safety, efficiency, and deployment.

Our work is not limited to one spray module. We combine aircraft compatibility, tethered water delivery, operating controls, and practical site workflows.

01 / PLATFORM

Flagship UAV integration

System development around platforms such as DJI M400 and T100, with configuration based on actual operating requirements.

02 / CLEANING

Tethered water delivery

Continuous cleaning-water supply designed to support high-altitude exterior cleaning without relying on limited onboard liquid capacity.

03 / OPERATION

Lean field deployment

Highly integrated controls and equipment help reduce the labor demand of cleaning operations and simplify site deployment.

UAV exterior cleaning operation
Why it matters

Replacing risky access with a more scalable workflow.

For tall buildings, power plants, chemical facilities, and other hard-to-reach exterior surfaces, the goal is to reduce dependence on manual high-altitude access while improving maintenance efficiency and repeatability.

  • Reduce high-altitude manual exposure 01
  • Lower labor demand during cleaning 02
  • Improve repeatability of exterior maintenance 03
  • Adapt systems to specific site conditions 04
Capability & collaboration

Built through application, testing, and real-world demonstration.

01 / TECHNOLOGY
