South African Customer Needs For Efficient Sludge Removal
The customer was a construction and port maintenance contractor in South Africa. They needed a safe and efficient way to remove underwater sediment in a reservoir. Their daily operations showed that old dredging methods could no longer meet project demands. They faced several key challenges:
Manual dredging was too slow and risky for workers.
Many working areas had very low visibility.
The underground space was narrow, making diver operations unsafe.
Long-term projects required stable suction and non-stop working hours.
They needed a supplier with experience in exporting to Africa and providing fast technical support.
Because of these needs, they wanted an Underwater Cleaning Machine that could work for long hours, finish tasks faster, and reduce labour risks.
How Our Robotic Underwater Cleaning Machine Met Their Needs
We recommended our YG-900 electric underwater cleaning robot, a model designed for ports, reservoirs, and industrial tanks. This unit was the best match for the customer’s site conditions and sludge density.
Key advantages of the Underwater Cleaning Machine:
A high-power pump that removes sediment quickly and smoothly
A strong crawler system that keeps the robot stable on complex underwater surfaces
A real-time camera system for clear dredging control
24/7 continuous working ability, which helps shorten project time
A modular structure that makes daily care and part replacement simple
Export Process And On-Site Delivery To South Africa
To make sure the machine matched the working environment, we customised the final configuration based on sediment density and working depth.
The export and delivery process included:
Full production, underwater testing, and quality inspection before shipment
Export packaging, ocean freight planning, and complete customs documents for South Africa
Remote installation guidance and online operation training
Technical support for the first week of operation until the robot ran smoothly on-site
The customer deployed the Underwater Cleaning Machine at a reservoir used for port water supply. The commissioning process was smooth, and the robot began dredging work immediately.
Customer Feedback After Using The Underwater Dredging Robot
After several weeks of work, the customer shared very positive feedback. They said the underwater dredging robot reduced dredging time by more than 40%. Operators also reported that the robot worked safely in narrow areas where divers could not enter. They noticed several improvements:
Suction remained stable during long hours
The working area became cleaner and deeper faster than expected
Energy use was lower, which cut operating costs
Communication with YG was smooth and helpful
The machine stayed stable even on soft and uneven underwater ground
Because of these results, they said they plan to purchase more units for future waterfront projects.
