International Customer Cases
Case 1: Australia – Chemical Plant Tank Cleaning
A chemical plant in Australia struggled with severe scale buildup inside storage tanks. Manual cleaning meant sending workers into confined spaces with chemical residue—slow, risky, and expensive. The plant manager purchased a YG robotic dredge with an explosion-proof motor. One operator controlled the machine from outside the tank using the remote screen. “We cut cleaning time by more than half, and my team no longer breathes toxic fumes,” the maintenance supervisor reported. “This little machine paid for itself in three months.”
Case 2: Nigeria – Oil Tank Sludge Removal
An industrial services company in Nigeria needed to clean crude-oil storage tanks. The working environment was flammable and dangerous for workers. YG customized a robotic dredge with explosion-proof electric motor and flame-retardant wiring. The customer reported cleaning time reduced by 50%. Safety risk dropped to nearly zero because workers no longer entered the tanks.
Case 3: Poland, – Lake and Pond Cleaning
Several European clients including customers from Poland, France, and Spain purchased YG robotic dredges for lake and pond cleaning. The machines restored water depth and improved ecosystem health. Customers reported 40-60% faster dredging speed compared with traditional methods. No need to drain lakes or close parks during cleaning.
A European client—from Poland—chose YG robotic dredges for lake and pond restoration. Traditional methods required draining water bodies and shutting down public access for weeks. With the YG dredge, operators worked remotely without disturbing visitors. A Poland park manager shared: “We restored our lake in five days instead of three weeks. The fish stayed, the ducks stayed, and our guests never even knew we were working.” Customers consistently report 40-60% faster completion times with minimal site disruption.

| Recovery System | Not included – pumps material out | Includes sluice boxes and riffles |
| Depth Range | 0.5 – 30 meters | 1 – 15 meters |
| Power Source | Electric motor (explosion-proof option) | Diesel engine |
| Mobility | Crawler tracks on muddy bottoms | Floating barge |
| Typical Users | Municipalities, farms, factories | Small-scale gold miners |
| Investment | Lower, factory-direct pricing | Higher due to recovery equipment |
| Support | Online training and spare parts | Limited, local mechanic needed |
Which one should you choose? If you need to clean sludge from a pond, lake, or tank – choose the mini dredge for sale. If you are mining for gold in a river – choose a gold dredge. Some customers buy both: the mini dredge for cleaning and the gold dredge for mining.
