Tackling Stubborn Moss on Stone Curtain Walls: Wisson's Cleaning Robots Offer an Effortless Solution

Stone materials, prized for their aesthetic appeal and durability, are widely used in urban building facades for shopping malls, hotels, and high-end residential projects. However, in humid weather, particularly during rainy seasons, porous stone surfaces retain moisture and foster moss or mold growth. This not only compromises building aesthetics but also causes stone degradation and discoloration, necessitating regular cleaning.

To address the growing demand for efficient curtain wall maintenance, property owners and managers are increasingly adopting UAV high-altitude cleaning solutions. Yet, early-stage drone cleaning technologies often deliver inconsistent results. Ordinary cleaning drones struggle with stubborn contaminants like moss, mold, and scale due to limitations such as excessive cleaning distances and rigid operational processes, failing to meet client expectations.

As the global leader in general-purpose soft robotics, Wisson Technology leverages its Pliabot® Flexible Embodied Intelligent Robot Technology to launch the Fanxi® High-Rise Curtain Wall Safety Cleaning Service. This solution combines "industry-leading compact drones + Pliabot® flexible embodied intelligent robots + patented dynamic intelligent water treatment systems," drawing on extensive operational expertise to deliver a proprietary "Safe & Powerful Cleaning" value proposition: zero-distance, anti-disturbance safety; spotless, streak-free cleanliness; and unmatched security and efficacy.

The flexible embodied intelligent architecture, powered by Pliabot® flexible joints and tactile AI, enables intelligent active/passive adaptive balancing. This effectively counteracts flight recoil and airflow disturbances while absorbing accidental collisions, allowing "zero-distance" drone operations and maximizing spray pressure. Meanwhile, multi-angle precision pneumatic control via flexible joints ensures thorough, streak-free cleaning. These capabilities make Fanxi® highly effective against stubborn contaminants like moss and mold on stone curtain walls.

Case Study: Efficient Moss Removal at Shenzhen Vanke Cloud City

Shenzhen Vanke Cloud City, a landmark community mall in Nanshan District’s Vanke Cloud City headquarters base, prioritizes facade cleanliness as part of its property management. To enhance cleaning efficiency and adopt智能化 solutions, the mall’s management recently tested UAV cleaning systems. Wisson’s Fanxi® High-Rise Curtain Wall Cleaning Service stood out during field trials, efficiently removing moss and earning strong endorsement.

Pain Points Addressed
Post-rainy season, the mall’s stone facades developed stubborn moss deposits. Traditional manual cleaning was inefficient, while ordinary cleaning drones failed due to limitations like inability to perform close-range power washing or ineffective cleaning agents. Fanxi® leveraged two core strengths: zero-distance, full-coverage cleaning via Pliabot® flexible robotics, and precision removal of stubborn moss/dust using DIC water treatment systems with tailored cleaning agents and processes. The results earned the property manager’s high praise.

Achievement Highlights

• 4x Efficiency Gain: Compared to manual operations.

• 35% Cost Reduction: Achieved through robotic automation.

• Stubborn Moss Eliminated: Effective removal of tenacious contaminants.

• Quality Assurance: Cleaning results met expectations and passed property inspection.

This case demonstrates how Wisson’s Fanxi® service, underpinned by Pliabot® Flexible Technology, resolves complex high-altitude cleaning challenges while advancing UAV-based operational standards in urban infrastructure maintenance.
