JIUSI Intelligent demonstrated the aerial tethered cleaning solution

With the continuous advancement of urbanization, the number of high-rise buildings is increasing in urban and rural areas of China. The facades of these buildings are not only a natural part of the urban landscape, but also an important barrier to protect the internal environment and operational efficiency of the buildings, which not only affects the user experience of high-rise residents and tenants, but also directly relates to the income from the sale or rental of the property. However, the long-term exposure of the exterior wall to the air makes it easy to accumulate dust stains, especially after the rainy season, and the mildew problem is particularly serious, and the cleaning and maintenance of the exterior wall has become a regular task of urban management and property management.

According to relevant data and estimates, the size of China's building exterior wall cleaning market is as follows:

According to the estimate of curtain wall buildings, China's current construction area has reached 50 billion square meters, of which curtain wall buildings account for 5%. With a low charge of 3 yuan per square meter and a cleaning frequency of twice a year, it is estimated that the domestic curtain wall cleaning market is more than 200-40 billion yuan.

According to the estimation of super high-rise buildings: by 2024, there are more than 1,400 high-rise buildings over 200 meters in China, and if the estimated method of cleaning costs per square meter of 3 yuan per square meter and cleaning twice a year is adopted, the potential size of China's exterior wall cleaning market can reach 67 billion yuan.

The vigorous development of the high-rise building exterior wall cleaning market not only reflects the rigidity and growth of cleaning demand, but also hints at the high cost behind it. At the same time, the commonly used and traditional manual high-altitude cleaning often has many problems such as low efficiency, high cost and high safety risk. Therefore, city managers, property managers, etc., are in urgent need of an efficient, safe and convenient cleaning solution to deal with many problems existing in the traditional manual high-altitude cleaning operation mode and some existing automation equipment:

The problem of traditional manual high-altitude cleaning

Efficiency-wise

Slow cleaning speed: Manual cleaning of exterior walls mainly relies on manual operation of cleaning tools, and the work speed of cleaning workers is limited. For high-rise buildings, where the exterior wall area is large, manual cleaning of a wall can take days or even weeks, which is far less efficient than the cleaning efficiency of automated equipment.

Limited working hours: Due to human fatigue and safety factors, workers cannot work continuously for long periods of time. Generally, the working hours of a day are limited, and it is also necessary to consider factors such as the weather, such as rain, strong winds, etc., it is impossible to carry out outdoor high-altitude work.

Cost 

High labor costs: As labor market prices rise, hiring professional aerial cleaning workers requires high wages. In addition, workers also need to undergo regular safety training, etc., which increases labor costs.

Expensive insurance: Due to the high risk of high-altitude cleaning work, companies need to purchase high accident insurance for workers, which is also a significant expense.

Security 

High risk of falling: Workers are suspended outside the building or standing in the gondola through ropes, the ropes may be worn and broken, and the gondola may malfunction, which can easily cause workers to fall and cause serious casualties.

Severe weather threat: The risk of working in weather such as high winds, heavy rain, and lightning is extremely high, but sometimes it may be risky to work in order to meet the deadline and other factors. And even in normal weather, working at high altitude for a long time is a huge test for the physical strength and spirit of workers, and it is easy to cause safety accidents.

Problems with some of the existing automation equipment

Adaptability issues

Poor adaptability of building structure: Some automatic cleaning equipment is designed for specific building structures, and for complex and changeable high-rise building structures, such as buildings with irregular shapes and prominent decorative parts, the equipment may not be able to fit the exterior walls well for cleaning, resulting in cleaning dead corners.

Limited material adaptability: Different building exterior walls are made of different materials, such as glass, stone, ceramics, etc., and existing automation equipment may not be effective in cleaning some materials, or may cause damage to special materials.

Technical limitations

Lack of precision: Automated equipment may not be able to control the cleaning force and position as accurately as manual cleaning during the cleaning process, and there may be over-cleaning or inadequate cleaning, such as scratches or detergent residues when cleaning glass curtain walls.

Complex fault maintenance: automation equipment is usually a high-tech product, once a failure occurs, the maintenance technical requirements are high, and the maintenance cost is also high. In addition, equipment failures can interrupt cleaning work and affect the entire cleaning program.

Security risks remain

Equipment stability risk: Although automated equipment reduces the risk of personnel working at height, the stability of the equipment itself is also a problem. For example, equipment may slip and tip over during the movement of the exterior wall of a building, which may cause harm to people on the ground and the building itself.

Power and communication problems: Automation equipment needs a stable power supply and communication signals to ensure normal operation, and if there is a power interruption or signal loss during the cleaning process, the equipment may get out of control, bringing safety risks.

Scene Pain Points

High security risk

Fall from height: Cleaners work at height, usually by hanging ropes outside buildings or standing in hanging baskets. The rope may be broken, worn, etc., and the gondola may also malfunction, and in the event of an accident, workers can easily fall from a height, causing serious personal injury or even life danger.

Bad weather impact: In the event of bad weather such as strong winds, heavy rain, and lightning, the working environment is more dangerous. However, in order to meet the deadline or the customer's requirements, the operation may continue when the weather conditions are slightly better but there is still a certain risk, which increases the probability of accidents.

Less efficient

Limited cleaning speed: Manual cleaning is slower than that of machines. Manual cleaning of a large area of exterior walls can take days or even weeks, especially for some super high-rise buildings or buildings with very large exterior walls, the manual cleaning time will be longer, which may affect the normal use or aesthetics of the building.

成本因素

人力成本上升：随着经济的发展和劳动力市场的变化，人工成本逐年上升。企业需要支付给清洁工人较高的工资、福利等费用，这增加了企业的运营成本。

保险费用高：鉴于高楼清洁工作的高风险性，企业需要为工人购买高额的意外保险，这也是一笔不小的开支。

作业灵活性差

固定轨道设备和一些自动化设备只能覆盖特定区域，难以适应各种复杂建筑外墙结构，灵活性差。
