Comparison Between Dulevo Urban Road Sweepers and Other Street Sweepers

Urban road sweepers are advanced machines designed to improve street cleaning efficiency. In general, all sweepers operate based on three core steps:

1. Sweeping debris into a collection area
2. Collecting waste into a hopper
3. Filtering dust before releasing clean air back into the environment

However, the key difference between brands lies in the technology used in step 2 (collection and cleaning mechanism).

1. Common Sweeping Technologies on the Market

Mechanical Sweeping

• Uses brushes + conveyor system
• Strong at collecting heavy and large debris (stones, sand, etc.)
• Weak at collecting fine dust
• May leave debris in uneven surfaces

Vacuum Sweeping

• Uses suction airflow (like a giant vacuum cleaner)
• Good at collecting light waste and dust
• Limited ability with heavy debris
• Narrow suction width → may miss dirt
• May release fine dust if filtration is limited

Regenerative Air (Circulating Air)

• Uses air flow to blow + suck debris
• Effective at collecting fine dust across full width
• Works well on uneven surfaces
• Weak at handling large or heavy waste

2. Dulevo Technology – Hybrid Advantage

Dulevo combines:

• 70% mechanical sweeping (conveyor system)
• 30% vacuum suction

This hybrid system delivers:

✅ Collects both large/heavy waste (up to 350 mm)
✅ Efficiently removes fine dust (PM10 > 99%, PM2.5 ~92%)
✅ Works well on uneven road surfaces
✅ Reduces missed debris compared to single-technology systems

This makes Dulevo particularly suitable for real-world conditions in Vietnam, where waste is mixed (sand, stones, plastic, organic waste, fine dust).

3. Dust Control & Filtration Comparison

• Mechanical sweepers: weak dust control
• Vacuum sweepers: moderate (depends on filter)
• Regenerative air: good dust capture but limited debris range
• Dulevo:
  • Advanced filtration system (cotton-polyester or Gore-Tex optional)
  • Dust capture efficiency up to 99.9% (PM10)
  • Optional Gore-Tex filter captures particles down to PM1

➡️ Result: Cleaner air output, minimal secondary pollution

4. Operational Efficiency Comparison

5. Conclusion

Compared to other street sweepers, Dulevo stands out due to its hybrid technology, offering:

• Superior versatility (handles all waste types)
• High dust control efficiency
• Better performance on uneven surfaces
• Reduced environmental impact

👉 In markets like Vietnam, where road conditions and waste types are highly variable, Dulevo is one of the most optimal and balanced solutions available.
