As urbanization advances, high-rise buildings are proliferating in cities and towns globally. Building facades are not only integral to the urban landscape but also serve as critical barriers protecting the interior environment and operational efficiency. They directly impact the experience of occupants and tenants, as well as property sale or rental income. However, facades exposed to the elements accumulate dust, grime, and severe mold stains, especially after rainy seasons, making cleaning and maintenance a routine yet challenging task for urban and property management.

The booming market for high-rise facade cleaning underscores the inelastic and growing demand, alongside the high costs involved. Traditional manual cleaning methods, still widely used, suffer from low efficiency, high costs, and significant safety risks. Consequently, urban managers and property owners urgently need an efficient, safe, and convenient cleaning solution to overcome the limitations of manual methods and existing automated equipment:

Problems with Traditional Manual High-Rise Cleaning:

Efficiency:

Slow Speed: Reliant on manual labor, cleaning large facades takes days or weeks, far slower than automated solutions.

Limited Work Hours: Worker fatigue, safety protocols, and adverse weather (rain, high winds) severely restrict operational time.

Cost:

High Labor Costs: Rising wages and mandatory safety training significantly increase expenses.

Expensive Insurance: High-risk work necessitates costly accident insurance premiums.

Safety:

High Fall Risk: Rope wear/breakage or gondola failures pose severe fall hazards, potentially causing fatal accidents.

Weather Threats: Operating in high winds, storms, or lightning is extremely dangerous. Even in fair weather, prolonged exposure strains workers physically and mentally, increasing accident risks.

Problems with Some Existing Automated Equipment:

Adaptability:

Poor Structural Fit: Equipment designed for specific buildings often struggles with complex shapes or protrusions, leaving cleaning dead zones.

Limited Material Compatibility: Effectiveness varies across materials (glass, stone, ceramic), potentially causing damage.

Technical Limitations:

Insufficient Precision: Difficulty controlling cleaning pressure and location precisely can lead to streaks, residue, scratches, or missed spots.

Complex Repairs: High-tech devices require specialized maintenance, leading to costly downtime and schedule disruptions.

Safety Risks Remain:

Equipment Stability: Devices can slip, fall, or topple during operation, endangering people and property below.

Power/Communication Issues: Power outages or signal loss can cause uncontrolled equipment movement, posing hazards.

Core Pain Points:

High Safety Risk: Significant danger of falls and weather-related accidents.

Low Efficiency: Slow manual cleaning times, especially for large or very tall buildings.

High Costs: Rising labor expenses and substantial insurance premiums.

Poor Flexibility: Fixed-track and some automated systems lack adaptability to complex facade structures.

Solution:

The Drone Cleaning Solution: A comprehensive system encompassing preparation, operation, and completion phases, including all necessary materials and equipment. Specifically designed for high-altitude, large-scale facade cleaning, it features high-pressure washing capabilities supporting water and cleaning fluids. Utilizing tether-assisted water supply, it enables extended, continuous operation for efficient cleaning of high-rise exteriors.

Operators control the drone from a ground station. Equipped with real-time video transmission and millimeter-wave radar assistance, the drone precisely locates target areas. It performs high-pressure, multi-angle cleaning on various surfaces, including glass curtain walls, stone facades, aluminum panels, and other building exteriors, tops, and ground-level surfaces.
