The challenge

Manual cleaning can't keep up with the pace.

Metro de Madrid is one of Europe's largest metro networks, with 300+ stations, ~300 km of track, and 736 million passengers per year. Station Sol alone welcomes 22 million passengers annually.

That constant flow of foot traffic causes a continuous buildup of dirt, dust, and debris around the clock. Traditional manual cleaning could not keep pace without enormous staffing requirements and high operational costs.

  • 🚶
    Continuous use, 24/7
    Trains run every 3–4 minutes during peak hours. Cleaning must match the rhythm of the city.
  • 📐
    Scale is the challenge
    Maintaining 300+ stations manually requires an army of cleaners and an unsustainable budget.
  • 🌿
    Sustainability targets
    Metro de Madrid is committed to reducing water and energy consumption. Manual methods offer no measurable reduction.

The solution

Three Gausium Scrubber 50 robots. Autonomous. Continuous.

Distributor Darlim, with 40+ years of experience, €27M in revenue, and 6,000+ active clients, deployed three Gausium Scrubber 50 units in the corridors of the metro stations. The robots operate autonomously alongside passengers, without supervision.

🧠
AI navigation & sensor fusion
LiDAR, 3D depth cameras, and RGB cameras work together for autonomous navigation in busy, complex environments, including alongside passengers and obstacles.
💧
Water-saving system: −80%
The integrated water recycling system actively reuses process water. Result: 80% less drinking water consumption compared to traditional floor scrubbers.
⚡
AI Spot Cleaning: 4× faster
Spot Cleaning mode automatically detects stains and soiling, concentrating cleaning power precisely where needed. Up to 4× more efficient than area-wide cleaning.
🔄
3-in-1: scrub, sweep, dust-mop
One compact robot combines three cleaning functions in a single pass. No need to switch equipment, ideal for narrow station corridors.
☁️
Cloud platform & remote monitoring
Managers schedule cleaning tasks, track the status of each robot in real time, and analyse cleaning data via a central cloud platform, all remotely.
🛡️
Safe alongside passengers
The robots automatically adjust their route around people and obstacles. They operate even during peak hours without posing any safety risk to passengers or staff.

Looking ahead

Expansion to Line 11 and Line 5.

Following the successful deployment at the initial stations, Metro de Madrid is planning further rollout to additional lines as passenger numbers continue to grow. The results prove that autonomous cleaning works at scale, even in one of Europe's busiest metro systems.
