The Shenzhen commercial building is located in the prosperous commercial office area of Longhua, with a height of 60 meters and a total of 18 floors. In recent years, frequent rainy and cloudy weather in Guangdong has led to the appearance of mold and dirt on the external walls of the building, which has seriously affected the appearance and image of the building. In order to maintain the high-end image of the building, ensure tenants' satisfaction and support the building's rental business, the building management office decided to seek for an efficient and safe external wall cleaning solution.

Challenges & Pain Points

Security Challenges

• Risk of falling from height: The most significant safety risk associated with manual high-rise cleaning is falling from height. Cleaning workers usually rely on equipment such as ropes and baskets to work on building facades, and any malfunction of such equipment, such as rope breakage, decoupling of baskets, or operator error on the part of the workers, can cause them to fall from heights, resulting in serious injuries and fatalities.
  
• Adverse Weather Impact: Weather conditions have a great impact on manual overhead cleaning operations. In inclement weather such as high winds, heavy rain, thunder and lightning, high or low temperatures, the danger of the operation increases exponentially. However, due to constraints such as work schedules, sometimes workers may have to work in weather conditions where certain risks exist.
  
• Limitations of safety equipment: Although there is safety protection equipment, such equipment may cause inconvenience to workers' operation and affect work efficiency. Moreover, after a long time of use, the safety equipment itself may be aged and damaged, increasing the potential safety hazards.
  

Efficiency and Quality limits

• Slow cleaning speed: Compared to automated equipment, manual cleaning of high rise facades is relatively slow. For large areas of facades, manual cleaning may take a longer time to complete, which is a big problem for some projects with high time requirements.
  
• Uneven cleaning results: Different workers have different skill levels, work experience and work attitude, which may lead to uneven cleaning results. Some areas may be cleaned very well, while others may have stains left behind, affecting the overall aesthetics of the building.
  
• Difficult to clean complex areas: For some complex areas on building facades, such as narrow crevices, decorative carved parts or higher corners, manual cleaning may be difficult and prone to cleaning in place.
  

Cost Factor

• Rising Labor Costs: As the economy grows and the labor market changes, labor costs continue to rise. Businesses need to pay higher wages, benefits and insurance costs to hire and retain janitors, which increases the cost of janitorial services.
  
• High cost of insurance: Given the high risk nature of aerial cleaning work, enterprises need to take out a high level of accident insurance for their workers, and the cost of insurance is also an important cost expense. And the cost of insurance is likely to increase further as the standard of compensation for safety accidents increases.
  

Solutions

The building management office, in collaboration with the JIUSI team, conducted a one-day operational inspection, photographed the building with an aerial drone, analyzed the overall dirty situation, and finally adopted the D15R as the core aerial tethered cleaning solution with a professional foam cleaner for mildew, to customize and implement a highly efficient, safe, and full-coverage cleaning solution for the building.

The core product of this solution, the D15R multi-functional cleaning drone, is a highly efficient cleaning equipment adapted to 2 types of mounts and 4 spray nozzles, providing 17m²/min, 20MPa high-pressure and rapid cleaning capacity, and supporting uninterrupted water supply operations to ensure long-time continuous operation. Its multi-angle, multi-scene coverage design is suitable for building facades, photovoltaic panels, insulator strings and other complex high-altitude cleaning tasks, a safe alternative to manual high-altitude operation.

Efficiently

• Continuous operation: support uninterrupted tethered water supply, not limited by the capacity of the water tank, to realize a long time of continuous cleaning operation.
  
• High-pressure cleaning: 20MPa maximum pressure quickly removes stubborn stains, and a cleaning speed of 17 square meters / minute significantly improves operational efficiency.
  
• Rapid Deployment: Compact size, easy to transport and stow, and slide-in interface design allows the device to be deployed in less than 1 minute.
  

Safety

• Instead of people working at height: the operator remotely controls from the ground, avoiding the safety risk of working at height.
  
• Dual RTK configuration: integrated RTK centimeter-level high-precision positioning module, with precise positioning capability, providing real-time centimeter-level positioning data, significantly improving the absolute accuracy of the data.
  
• Intelligent Obstacle Avoidance Sensing System: with radar obstacle avoidance front vision sensor, real-time sensing of the surrounding obstacle information, so that the flight is more at ease.
  

Multi-scenario

• Modularized design: the best mounting and nozzle can be selected according to different tasks to meet the needs of various high-altitude and complex environment cleaning.
  
• Stable operation at high altitude: the highest flight altitude of 60 meters, adapting to a variety of height cleaning needs.
  
• Flexible operation: it can travel flexibly, not afraid of narrow building distance and other complex building space.
  
• Multi-angle coverage of the bottom and top surfaces: support for different configurations optional, easy to cover the bottom and top surfaces and other complex surface cleaning.
  
  
  
  

Customer Benefits

By applying the intelligent solutions of JIUSI, relying on the D15R multi-functional cleaning and supporting cleaning agents, the building's exterior wall cleaning has achieved the expected results, which has brought the customer multiple benefits compared with the traditional manual work:

Significantly improved safety

Remote operation avoids the risk of operators working at height and ensures personal safety.

Efficiency doubled

The speed of cleaning is greatly increased, only a few hours to complete the traditional method of work can be completed in a few days, without affecting the tenant's experience.

Cleaning is comprehensive and in place

High-pressure cleaning and multi-angle coverage design ensures that every corner is thoroughly cleaned, maintaining the building's aesthetics and structural integrity.

Significant Cost Reduction

Reduced labor costs and equipment rental costs improve the overall economics of the operation.

Environmentally Friendly

Specialized cleaning agents are used only for stubborn dirt, and high-pressure water flow is used for most of the work surface, reducing the environmental impact of the cleaning process and protecting the building surface and the surrounding environment.
