Fifty Years of Dulevo : Engineering Innovation in Urban and Industrial Cleaning

The story begins in 1976, in a context where the street sweeper sector was still largely based on standardized solutions.
Dulevo was founded with a different approach: designing and manufacturing the technological core of its machines in-house.

From the very beginning, the objective was clear: to develop solutions capable of ensuring sweeping efficiency, effective dust control, and long operational life.

Dulevo became a pioneer in the development of mechanical suction filter sweeping technology, a solution that would become one of the company’s defining elements and that still represents the cornerstone of its street sweepers today.

During the 1980s and 1990s, Dulevo strengthened its presence in Italy and in international markets by developing models characterized by robustness, reliability, and ease of maintenance.
The company’s reputation grew thanks to machines designed to work continuously while maintaining high performance over time.

An important strategic step came with Dulevo joining the Fayat Group, an international industrial organization operating in the construction and infrastructure sectors.

This integration strengthened the company’s capacity to invest in research and development and enabled it to address the new challenges of the industry with greater solidity: increasingly stringent environmental regulations, technological evolution, and the energy transition.

At the same time, Dulevo retained its technical and production center of expertise, preserving the know-how developed over decades.

Dulevo’s evolution is based on values that translate into concrete design choices.

Quality means designing machines built to last, with carefully selected components and systems tested under real working conditions.

Performance means high sweeping efficiency and strong operational productivity.

Environment means developing solutions capable of reducing environmental impact and improving fine dust control.

People means focusing on those who use the machines every day, operators and maintenance technicians, as well as on the citizens who live in urban environments.

Time means machines designed to optimize working time and simplify maintenance operations.

These principles are summarized in the company’s payoff: Timeless Quality through Passion.

The mechanical suction filter system represents one of the most distinctive elements of Dulevo street sweepers.

Its operation is based on the combination of three main elements:

• brushes that collect debris from the ground
• a conveyor system that transfers it into the hopper
• a suction and filtration system that captures dust and particulate matter

This technology allows effective operation even without the use of water, ensuring significant water savings without compromising cleaning performance.

The result is a best in class solution in three key aspects: water savings, fine dust filtration, and operational productivity.

Greater productivity also means lower energy consumption and more efficient working cycles.
The range also includes both electric and gas-powered solutions.

Among the most advanced solutions in the Dulevo range is the D.zero² 3.5t, a 100% electric street sweeper.

Designed to operate in the most sensitive urban environments, it combines a lightweight structure with an optimized chassis to ensure strength and reliability.

The electric powertrain reduces local emissions and energy consumption, making it particularly suitable for urban areas where operational sustainability is increasingly important.

The project integrates vehicle architecture, energy management, and the sweeping system to guarantee high performance even in everyday urban cleaning operations.

With the D6 Veloce, Dulevo offers a street sweeper designed to deliver high productivity and exceptional operational versatility.

A transfer speed of up to 80 km/h allows rapid movement between different work areas, reducing downtime and improving operational efficiency.

The machine ensures high sweeping speed and is capable of collecting both light materials and heavier debris.
It can operate in a wide range of environmental and weather conditions, from intense heat to colder temperatures, consistently maintaining high performance.

The 850 model continues to be one of the most recognizable machines in the Dulevo range, demonstrating outstanding reliability and durability over time.

Its high sweeping efficiency ensures constant productivity and helps reduce working time. At the same time, easy access to components and simplified disassembly reduce maintenance time.

In this way, technology gives time back to the people who use the machines every day and to the communities that benefit from cleaner urban spaces.

A focus on sustainability, the evolution of electric platforms, the integration of digital solutions, and the optimization of operational cycles represent developments that are consistent with an already well-defined identity looking toward the future.

Dulevo street sweepers embody a shared principle of durability, efficiency, operator care, and environmental responsibility. They are machines designed to maximize working time, reduce operating costs, and improve the quality of shared spaces.

Fifty years after 1976, the trajectory remains faithful to its origins: to innovate without losing coherence, to grow without diluting identity, and to look to the future while preserving the technological core that has made Dulevo a benchmark in the sector.
