As modern cities' "flowing business cards," subways are not only core transportation hubs for residents but also vital windows showcasing urban civilization. From elevated platform facades to entrance canopies, and from elevator shaft exteriors to public areas around platforms, the cleanliness of subway facilities directly impacts passenger experience and urban image.

In recent years, with the rapid expansion of national rail transit networks, some cities have pioneered the integration of intelligent cleaning into rail operation and maintenance systems, using technology to address industry pain points like difficult高空作业, low manual efficiency, and high safety risks. Leveraging its unique flexible embodied intelligent operation modules—combining flexible hardware and embodied AI—Wisson's AP3-P3 Flexible Tethered Cleaning System has successfully conducted multiple elevated platform cleaning operations at subway stations in Tianjin, Shenzhen, Chengdu, and other cities. It has earned widespread acclaim from rail transit groups and gradually formed standardized elevated cleaning solutions covering multiple rail transit scenarios.

Case Study: Wisson's P3 Robots Empower Chengdu Subway's "Clean & Beautiful" Initiative

This year, Chengdu launched the citywide "Clean, Excellent, Bright & Beautiful · World Games Ambassador" campaign, prioritizing upgrades to urban public space quality. As a core infrastructure of urban transportation, Chengdu Subway's over 300 stations have seen meticulous maintenance and beautification of wind pavilions, green belts, canopies, entrances, and station halls. A clean Chengdu Subway has become the city's "gateway ambassador."

To create a cleaner, more aesthetically pleasing rail environment and enhance passenger experience, Chengdu Rail Transit Group partnered with Wisson Technology to introduce the AP3-P3 Flexible Tethered Cleaning System for intelligent cleaning of platform canopies and elevator shaft exteriors at Shuangshuinian Station. This initiative significantly reduced labor costs, improved operational efficiency, and advanced the intelligent upgrading of Chengdu's rail cleaning operations, empowering the "smart city"标杆形象.

Pain Points Addressed

Subway platform canopies, typically aluminum-clad elevated structures, accumulate heavy dust and water stains from years of exposure. Traditional cleaning methods face multiple challenges:

1. Manual Inefficiency: Elevated facilities like platform canopies require labor-intensive, time-consuming manual work, with irregular structures (e.g., aluminum seams, bolt holes) creating cleaning dead zones.

2. Equipment Limitations: Rigid canopy-cleaning robots struggle to adapt to curved surfaces, risking collisions and damage to equipment or stations. Frequent recalibration for multi-site environments prolongs deployment.

3. High Costs: The sheer volume of stations and cleaning tasks drives significant operational pressure from prolonged labor investment.

   
   

   
   

Achievement Highlights

Wisson's AP3-P3 system leveraged Pliabot® Flexible Embodied Intelligence to deliver "zero-distance, collision-resistant" safety and flexible, full-coverage cleaning. It overcame manual limitations, achieving efficient, high-quality results:

• 40% Efficiency Gain: Compared to manual operations.

• 30% Cost Reduction: Through robotic automation.

• Safety Risks Eliminated: Zero human exposure to hazardous environments.

• Surface-Specific Cleaning: Specialized detergents effectively removed aluminum stains without emitting harsh odors, ensuring public and environmental safety.

As Chengdu Rail Transit continues its environmental upgrade campaigns, Wisson's AP3-P3 system is poised to support more stations in the "Clean & Beautiful" initiative, contributing "flexible robotics" power to shaping Chengdu's urban gateway.
