With the acceleration of urbanization, cleaning and maintenance issues of high-altitude buildings, bridges, power facilities, etc. have become increasingly prominent. Traditional manual cleaning methods are not only inefficient and costly, but also pose safety risks in high-altitude operations. High-pressure water jet cleaning technology carried by drones has emerged as the times require, and with its unique advantages, it has become a new solution to this problem. This technology uses a high-pressure water jet device on a drone platform to achieve long-distance, high-altitude, and precise cleaning operations, with the advantages of high operating efficiency, low cost, and good safety.

In recent years, revolutionary technology has redefined the way high-rise building maintenance is approached. Drone-based exterior wall cleaning systems have set a new benchmark in the industry by combining efficiency with unparalleled safety. This innovative solution marks a significant milestone in the field of building maintenance, offering both technological advancements and operational breakthroughs.

With the continuous advancement of urbanization, the number of infrastructure such as high-rise buildings, photovoltaic power stations and high-voltage transmission lines has increased year by year, and the high-altitude cleaning market has also developed rapidly. According to market research reports, the global high-altitude cleaning market is expected to grow at a compound annual growth rate of 6.3% in the next few years, and the market size will reach US$4.6 billion by 2028.

A major energy enterprise operating large-scale wind farms across southwestern China faced critical challenges with turbine icing during winter months. In high-altitude regions with low temperatures and high humidity, freezing rain leads to significant ice accumulation on wind turbine blades. This results in increased structural fatigue, reduced equipment lifespan, lower energy output, and serious safety concerns for the wind farm.
To ensure continued operation in freezing conditions, regular anti-icing measures are essential. However, traditional de-icing methods—such as manually dislodging ice with tools on elevated platforms—are inefficient, labor-intensive, and pose high safety risks. In search of a scalable, intelligent solution, the company aimed to prevent icing proactively and improve operational reliability across its sites.

Stone is a widely favored material for building façades due to its durability and aesthetic appeal. It is often used in the exterior curtain walls of malls, hotels, and high-end residences. However, in humid climates—especially during the rainy season—stone surfaces are prone to retaining moisture due to their porous structure, making them ideal breeding grounds for moss and mildew. These biological stains not only compromise the appearance of buildings but may also lead to material deterioration and discoloration over time, requiring regular maintenance and cleaning.

In front of the main building of the Greater Bay Area Data Application Industrial Park, an innovative demonstration drew widespread attention — a professional drone equipped with a high-pressure sprayer and rotating brush steadily took off, hovering close to the glass curtain wall of the high-rise. As the operator adjusted the controls, the drone began an automated cleaning process, spraying cleaning solution and scrubbing away years of accumulated dust. Within moments, the dull façade started to regain its original shine — a vivid example of how low-altitude economy is reshaping urban services.

Recently, the AP3-P3 flexible tethered aerial cleaning system achieved DJI M400 PSDK mass production certification, becoming one of the first aerial cleaning payloads to pass this rigorous process. This milestone marks an important step forward in scaling aerial cleaning applications, bringing safer, more efficient solutions to high-altitude operations.
