CASE STUDY: The Sweeper Powered by the Sun

Solar Powered Electric Street Sweeping Solution

Scarab Sweepers' sister company, Mathieu, has developed an integrated, sustainable urban cleaning solution through its innovation “Je roule au soleil”.

This concept combines the all-electric compact sweeper - the RAVO E2, solar-powered charging infrastructure, and smart cleaning optimisation tools to deliver a fully decarbonised approach to municipal cleaning operations.

THE CHALLENGE

Municipalities across Europe are under pressure to:

  • Reduce carbon emissions in urban operations.
  • Lower total cost of ownership (TCO).
  • Overcome rising electricity and fuel costs.
  • Maintain high standards of cleanliness with limited resources.

Additionally, reliance on grid electricity can limit sustainability if the energy supply is not fully renewable.

THE SOLUTION

“Je roule au soleil” delivers a complete ecosystem, integrating:

  • RAVO E2 Electric Sweeper – zero-emission, low-noise urban cleaning.
  • Photovoltaic Canopy (Solar Carport) – generates renewable energy on-site.
  • EV Charging Stations – powered directly by solar energy.
  • CleanCity® Platform – AI-driven system for optimising cleaning operations.

Together, these components create a self-sufficient, solar-powered cleaning solution, enabling municipalities to operate independently from conventional energy sources.

PERFORMANCE HIGHLIGHTS

  • 100% electric operation with zero emissions.
  • Quiet performance, enabling work at any time of day.
  • High suction and cleaning efficiency comparable to diesel alternatives.
  • Daily charging powered by renewable solar energy.

The system enables reliable, full-service urban cleaning while reducing environmental impact.

THE DEPLOYMENT MODEL

The system operates with a simple daily cycle:

  • The sweeper performs cleaning operations during working hours.
  • It is then recharged using solar-generated electricity via on-site charging infrastructure.
  • AI-powered tools analyse urban cleanliness and optimise routes in real time.

This closed-loop model ensures efficient energy use while maximising operational output.

COST BENEFITS

“Je roule au soleil” is designed to deliver long-term financial advantages:

  • Lower total cost of ownership compared to diesel sweepers.
  • Free daily energy from solar generation.
  • Reduced fuel and maintenance costs.
  • Optimised operations via smart route planning.

This creates a more predictable and sustainable cost model for local authorities.

KEY OUTCOMES
