Sustainable Urban Cleaning Solution
The Green Machines GM 720ze is an innovative, fully electric sweeping machine designed for use in cities and industrial areas. Powered by a high-performance lithium-ion battery system from ecovolta, it offers an emission-free, low-noise, and efficient alternative to conventional diesel-powered sweepers.

Efficient Battery System with High Capacity
At the heart of the GM 720ze is a state-of-the-art lithium-ion battery system with a 60 kWh capacity. This powerful battery enables continuous operation for a full 8-hour work shift without the need for intermediate charging (8 h). Its high energy density ensures a long lifespan and minimal maintenance requirements. Additionally, the entire vehicle operates at a low voltage of 48 V to meet safety standards..
Maximum Range and Short Charging Times
The electric sweeper is designed for maximum efficiency. By intelligently switching between sweeping and driving modes, energy usage is optimized. The charging time from 20-80 % is approximately 4 hours, ensuring the sweeper is quickly ready for use again.
Advantages of an electric sweeper for cities and municipalities
Transitioning to electromobility offers numerous benefits for urban areas:
- CO₂ reduction: No direct emissions during operation
- Less noise & fine dust: Improved air quality and quieter operation
- Low operating costs: No diesel, reduced maintenance
- Sustainable urban cleaning: Ideal for environmentally conscious municipalities
Challenges and solutions
Electrifying off-highway vehicles requires a well-thought-out integration of the battery system. Green Machines and ecovolta engineers worked closely to balance weight, performance, and energy efficiency. Thanks to the modular design of the ecovolta battery system, optimal adaptation to the vehicle architecture was achieved. A key advantage is the flexible placement of battery modules in confined spaces, ensuring optimal vehicle design utilization.
Sustainable urban cleaning with the GM 720ze
The GM 720ze, introduced as a new product this year, sets new standards for environmentally friendly urban cleaning. With the integration of the ecovolta battery system, it has been established as a powerful, fully electric sweeper. It meets the highest requirements for sustainability, cost-effectiveness, and user-friendliness. More and more cities and municipalities are adopting this emission-free solution to enhance the quality of life in urban areas.
