2. Industry Pain Points

Fatal Flaws of Traditional High-Altitude Cleaning:

· Severe Safety Risks:
Rope-access “spider-men” cleaning has an annual accident rate exceeding 0.8%; in 2024 alone, 584 fatalities from high-altitude falls in China.

· Inefficient and Costly:
Cleaning a 300-meter skyscraper typically requires a 30-person crew over 15 days, with labor accounting for over 65% of the total cost.

· Operational Restrictions:
Work halts during bad weather; complex façades (curved glass, hollow structures) are hard to reach; high-risk zones in power/chemical plants restrict manual access.

· Environmental and Social Disruptions:
Scaffolding blocks traffic; chemical cleaners pollute building surfaces and surrounding environment.

Limitations of Conventional Drone Cleaning:

· Payload <10kg

· Flight time <20 minutes

· Water pressure <5MPa
→ Insufficient for continuous, commercial-scale operations

4. Proven Results

Transforming Façade Cleaning Industry

Shanghai Tower Case Study:

· 4 systems in parallel → Cleaned 632m tower crown in 7 days (traditional method: 45 days)

· Zero accidents + 40% water saving + 52% total cost reduction

· Client Testimonial: “No more insurance nightmares or labor shortages—we now confidently accept ultra-high-rise contracts over 200m.”

Boosting Power Plant Maintenance Efficiency

1 GW Thermal Power Plant Insulator Cleaning:

· Two systems conducted live-line cleaning → 12 towers cleaned per day

· Traditional methods require 8 hours of shutdown per tower

· Savings: Avoided production loss of CNY 1.6 million/day

· Test Data: Flashover voltage restored to 98.3% of new equipment standard

Upgrading Chemical Plant Safety Standards

Ethylene Reactor Anti-Corrosion Coating:

· Drone proximity spraying of special coatings in toxic environments

· Results: Project duration reduced to ¼ original time; zero high-risk insurance payouts

Authoritative Certification & Endurance Validation

· Certified by China National High-Altitude Equipment Quality Inspection Center

· Over 3,000+ hours of uninterrupted operation in typhoons, freezing rain, and other extreme conditions
