About This Supplier
Company Overview
Guangdong Lingdu Intelligence Technology Co., Ltd. (Lingdu Intelligence) is a National High-tech Enterprise and a Guangdong Provincial Specialized and Sophisticated SME, founded in 2021. The company’s founding team began R&D in Xiamen in 2016, driven by a mission to eliminate the life-threatening risks faced by traditional “spider-man” window washers. Lingdu Intelligence focuses on the R&D, production, and sales of intelligent cleaning robots for high-altitude curtain walls. The company has accumulated over 200 patents and its products are exported to more than 20 countries and regions worldwide.
Canopy / High-Altitude Curtain Wall Cleaning Robot Products
Lingdu Intelligence has developed two flagship products specifically for cleaning high-rise building facades: the Lingkong K3 and the Lingyun Y3.
1. Lingkong K3 — High-Altitude Curtain Wall Cleaning Robot
The Lingkong K3 is Lingdu Intelligence’s first mass-produced flagship product. It is designed for flat curtain wall surfaces and has gained significant market traction, winning the “Supreme Gold Award” at the 136th Canton Fair Design Innovation Award (CF Award) in 2024.
Key Specifications & Features:
| Feature | Specification |
|---|---|
| Cleaning Efficiency | 1,200–2,000 m²/day (3x faster than manual labor) |
| Maximum Operating Height | Up to 600 meters |
| Adhesion System | 8 suction cups utilizing vacuum negative pressure |
| Machine Weight | Approximately 70+ kg, with an adhesion force of 200 kg |
| Water System | Built-in 9L circulating water tank |
| Wind Resistance | Stable operation in winds up to Force 12 |
| Applications | Hotels, office buildings, shopping malls, and railway stations |
| Price | 338,000 RMB per unit |
The Lingkong K3 features an innovative water recycling and filtration system that reduces water consumption from the traditional 50–200 tons per clean to just 200–500 liters. The machine is equipped with a proprietary safety locking system that, even in the event of a power failure, ensures the robot remains securely attached to both the wall and the safety rope.
2. Lingyun Y3 — Obstacle-Crossing Curtain Wall Cleaning Robot (3rd Generation)
Launched in November 2025, the Lingyun Y3 is Lingdu Intelligence’s third-generation cleaning robot. It represents a major technological breakthrough, as it is the first robot in China to feature active gait-based obstacle-crossing technology for high-altitude curtain walls.
The Core Problem It Solves: Traditional curtain wall cleaning robots can only operate on flat, unobstructed surfaces, covering less than 30% of building facade scenarios. The Lingyun Y3’s obstacle-crossing capability expands this coverage to over 60%.
| Feature | Specification |
|---|---|
| Obstacle-Crossing Height | 20 cm active obstacle clearance |
| Continuous Operation | 7 hours |
| Water System | Built-in 19L water circulation base |
| Water Savings | 98% water conservation |
| Appearance | Ice-blue, futuristic design |
- “Eyes”: Millimeter-level visual recognition system that detects protrusions, seams, and obstacles on the wall surface
- “Brain”: An AI model trained through hundreds of thousands of virtual simulations that can perform “health checks” on building facades and make autonomous decisions
- Real-time Motion Control: Enables the robot to freely navigate vertical, inclined, and obstacle-filled walls, avoiding window frames and other obstructions without collision
Development History: The R&D team conducted extensive research and found that the height of window frames on most glass curtain wall buildings is concentrated around 20 cm. They set this as their technical target and developed the active gait-based obstacle-crossing technology, continuously refining the mechanical structure and core algorithms to achieve the final product.
Summary
| Product | Type | Key Strength | Target Scenario |
|---|---|---|---|
| Lingkong K3 | Flat-surface cleaning robot | High efficiency, proven reliability, water recycling | Standard flat curtain walls |
| Lingyun Y3 | Obstacle-crossing robot | 20 cm active obstacle clearance, AI vision, 98% water savings | Complex facades with window frames and obstructions |
Both products replace dangerous manual “spider-man” labor with safe, efficient, and intelligent robotic solutions.
