Common Needs of Nigerian Customers
Customers in Nigeria and West Africa generally face the following problems:
1: Difficulty in Cleaning Sediment from Chemical Plants and Oil Tanks
Traditional manual cleaning poses safety hazards and is inefficient. Customers hope to improve safety and cleaning efficiency through automated equipment.
2: Difficulty in Cleaning Sludge from Lakes and Plant Pools
Some plants and environmental remediation projects require the treatment of large amounts of sludge, and traditional equipment struggles to access shallow water or confined areas.
3: Long-Term Investment Cost-Effectiveness Considerations
Customers want equipment that is both safe and efficient, while also reducing labor and maintenance costs in the long run.
These realities not only apply to Nigerian customers but also resonate with customers in other countries. For example, a South African customer used an automated dredging robot to clean lake silt, achieving stable and reliable results. See the South African case study.
A European customer has also received positive feedback from using automated dredging robots in chemical plants and lake remediation. See the European case study.

Frequently Asked Questions from Nigerian Customers
Q1: Is a special operating certificate or permit required?
A: No. Operation is similar to a remote-controlled vehicle; 1-2 hours of training is sufficient to learn how to use it.
Q2: Can the equipment be used in flammable environments?
A: Yes, explosion-proof motors and safety control systems ensure safe operation in oil tanks and chemical plants.
Q3: What are the limitations on sludge transport distance and depth?
A: Standard operating depth is 0.5–6 meters, and sludge transport distance can reach 100–200 meters. Customization is available.
Q4: Is maintenance complex?
A: Maintenance is simple, requiring only periodic inspections of the pump body, track system, and wiring.
Q5: Is it a worthwhile investment?
A: For companies that regularly clean sludge from oil tanks, chemical plants, or lakes, purchasing an automatic sludge removal robot offers high cost-effectiveness, stable efficiency, and significant long-term benefits.
