Success cases | 3U intelligent drone cleaning solution to renovate the exterior wall of Guangzhou Building

Located in Guangzhou’s bustling business district, Guangzhou Tower is 80 meters high and has 25 floors. In recent years, frequent rainy weather in Guangdong has led to mold, dirt and stains on the exterior walls of buildings, seriously affecting their high-end image and tenant satisfaction. In order to maintain the building’s excellent appearance, support the leasing business and ensure structural safety, the Building Management Office decided to look for an efficient and safe external wall cleaning solution.

Challenges and pain points

·Risk of falling from height: The main safety hazard of artificial high-rise building cleaning is falling from height. Cleaners rely on ropes or baskets to work and equipment failures (e.g., rope breakage, basket decoupling) or operator errors can result in serious injuries or injuries.
·Severe weather impact: Severe weather such as high winds, heavy rain, lightning or extreme temperature differences significantly increase the risk of manual cleaning. Despite tight deadlines, workers sometimes had to work in risky conditions.
·Safety Equipment Limitations: Although safety equipment is available, it may affect the flexibility of operation, and long-term use may also increase the hidden danger due to aging or damage. Efficiency & Quality Limitations

Solution

The building management office cooperated with the Jiusi intelligent team to conduct a one-day operation inspection, photographed the building through aerial drones, analyzed the overall dirt situation, and finally adopted the aerial tethered cleaning solution with C15 as the core, with professional foam cleaner for mold, to customize and implement an efficient, safe and full-coverage cleaning solution for the building.

The core product in this solution, the C15 multi-functional cleaning drone, is an efficient cleaning equipment suitable for 2 kinds of mounts and 4 nozzles, providing a high-pressure rapid cleaning capacity of 17m²/min and 20MPa, supporting uninterrupted water supply operations and ensuring long-term continuous operation. Its multi-angle and multi-scene coverage design is suitable for complex high-altitude cleaning tasks such as building exterior walls, photovoltaic panels, and insulator strings, and safely replaces manual high-altitude work.

High-Efficiency

Supports continuous tethered water supply, free from water tank limits for long-term cleaning. With 20MPa max pressure, it quickly removes stubborn stains at 17㎡/min. Compact design allows easy transport/storage. Slide-in interface enables 1-min deployment, boosting efficiency.
