Case Study: Wisson's Aerial Tethered Cleaning Solution Revitalizes Shenzhen Landmark Building

2024-08-28

Background

Shenzhen is one of the four major cities in China and a key research and manufacturing hub for high-tech industries in the southern region. It is often referred to as the "Silicon Valley of China." The client's high-end commercial building is located in a bustling business district of Shenzhen, standing at 184 meters (603 ft) with 43 floors and tens of thousands of square meters of curtain wall, is a landmark in the area. The frequent rainy weather has led to mold and dirt accumulation on the building's exterior, severely affecting its appearance. The complex structure and narrow spaces of the high floors make traditional manual cleaning inefficient and risky. To maintain the building’s prestigious image, ensure tenant satisfaction, and support leasing business, the building management sought an efficient and safe exterior cleaning solution.

challenges

Risk of High-altitude Work: Traditional manual high-altitude cleaning methods require workers to be suspended at heights, posing significant safety risks despite stringent qualification and experience requirements.

Difficulty Cleaning Complex Structures: The building's intricate facade and numerous narrow spaces make it difficult for traditional methods to thoroughly clean, especially in corners and crevices.

Weather Impact: Continuous rainy weather fosters mold and dirt growth on the exterior walls, necessitating frequent cleaning. Traditional methods are time-consuming and difficult to deploy quickly.

High Labor Costs: Manual cleaning requires substantial manpower, leading to high costs and low efficiency, making it challenging to complete large-scale cleaning quickly.

Solution

The building management collaborated with Wisson’s team for a three-day site survey, using drones to capture the overall dirt condition, and decided to use the Wisson Orion AP3-P3 Pliabot® Aerial Tethered Cleaning System and a specialized foam cleaner for mold. This system, suitable for drones with a 3-10kg (6-22lbs) load, provides high-pressure quick cleaning at 600㎡ (6,458 ft²) per hour with 13MPa pressure and supports continuous water supply, ensuring long-term operation. It is designed to handle complex high-altitude cleaning tasks like building facades, photovoltaic panels, and insulators safely, replacing manual high-altitude work. Integrated with drone's flight system, it allows single-person integrated control, offering a convenient and efficient cleaning solution.

Efficiency

Continuous Operation: Supports tethered water supply without tank capacity limitations, enabling prolonged cleaning operations.
High-Pressure Cleaning: 13MPa maximum pressure quickly removes stubborn stains, and the 600㎡ (6,458 ft²) per hour cleaning speed significantly boosts efficiency.
Quick Deployment: Compact size, easy transport and storage, and slide-in interface design enable deployment in just 1 minute.

Safety

Replaces High-Altitude Manual Work: Operators control the system remotely from the ground, eliminating high-altitude work safety risks.
Adaptive Balancing: The flexible gimbal adapts to eliminate side-sway during operation, effectively counteracting flight interference from spray recoil, ensuring operational stability.
Real-Time Distance Measurement: Laser module displays the working distance in real-time, ensuring stable and optimal spray distance.

Versatility

Narrow Space Operations: Fits drones with 3-10kg load, allowing flexible navigation in narrow spaces and adapting to complex cleaning environments.
Multi-Angle Coverage: Adjustable operation rod easily cover the bottom, top, and other complex surfaces for comprehensive cleaning.
Modular Nozzles: Various nozzles fit different tasks, meeting diverse high-altitude cleaning needs.

Benefits

By using Wisson’s solution and the Orion AP3-P3 Pliabot® Aerial Tethered Cleaning System with the corresponding cleaner, the building’s exterior cleaning achieved the expected results, offering multiple benefits over traditional manual methods:

Significantly Improved Safety: Remote operation avoids high-altitude work risks, ensuring personal safety.
Dramatically Increased Efficiency: Cleaning speed increased, completing tasks in hours that previously took days without disrupting tenant experience.
Thorough Cleaning: High-pressure and multi-angle coverage design ensures every corner is thoroughly cleaned, maintaining the building’s aesthetics and structural integrity.
Reduced Costs: Lower labor and equipment rental costs, enhancing overall economic efficiency.
Environmentally Friendly: Using specialized cleaner only for stubborn stains, with high-pressure water for most surfaces, minimizing environmental impact and protecting the building’s surface and surroundings.
Enhanced Brand Image: Efficient and safe cleaning maintenance improved the building’s premium appearance, enhancing tenant satisfaction and trust.

This cleaning project allowed the client to experience the high efficiency and safety of Wisson's Orion AP3-P3 Pliabot® Aerial Tethered Cleaning System. This innovative solution has been implemented in multiple cities and commercial buildings, not only for building facades but also for photovoltaic panels, insulators, towers, and other high-altitude cleaning scenarios. It provides efficient, safe cleaning solutions for various industries and contributes to the growth of the low-altitude economy (economic activities and industries related to the development and utilization of low-altitude airspace) in china by driving innovation in high-altitude cleaning technology.
