Saudi Arabia continues investing heavily in wastewater treatment facilities, industrial parks, desalination infrastructure, and municipal drainage networks. As these facilities expand, operators face increasing pressure to remove accumulated sludge while minimizing downtime and improving workplace safety. Manual dredging methods often expose workers to confined spaces, hazardous gases, and unstable sludge conditions. Because of these challenges, automated cleaning equipment has become an increasingly practical solution.
In early 2025, a wastewater treatment contractor from Dammam contacted YG Machinery after searching online for a Remote Control Dredging Robot suitable for industrial sludge removal. The company maintained several municipal wastewater plants and industrial sedimentation tanks for government infrastructure projects. Their maintenance team wanted equipment capable of operating continuously inside tanks without requiring workers to enter hazardous environments.
During the initial email exchange, the customer explained that existing cleaning methods relied heavily on manual excavation and vacuum trucks. Although those methods completed the work, they required long shutdown periods, large maintenance crews, and extensive safety preparation before workers could enter confined tanks. Management hoped to introduce robotic cleaning equipment that would improve productivity while reducing operational risks.
YG Machinery responded by requesting detailed project information rather than recommending equipment immediately. Our engineers collected data regarding sludge characteristics, tank dimensions, access openings, cleaning frequency, discharge distance, and daily operating requirements. These engineering details became the foundation for selecting the most appropriate robot configuration.
Several days later, both companies arranged an online technical meeting. During the discussion, the customer shared videos and layout drawings of the treatment facility. After reviewing every operating condition, YG Machinery recommended the YG900 configuration, which combined high pumping capacity, stable crawler movement, and wireless remote operation. That engineering consultation marked the beginning of a successful cooperation between the two companies.

Understanding The Customer’s Requirements
The online engineering meeting focused on the customer’s actual operating environment rather than product specifications. Every sludge removal project differs in tank size, sludge density, water depth, and access conditions. Selecting the correct robot required a complete understanding of these factors before production could begin.
The Saudi contractor maintained three wastewater treatment facilities serving nearby industrial zones. Most cleaning work involved sedimentation tanks, sludge storage basins, and underground wastewater channels. Some tanks had limited access openings, while others contained compacted sludge that accumulated after long operating cycles. Manual cleaning exposed workers to confined spaces and required lengthy preparation before maintenance could begin.
Several operational requirements became clear during the discussion.
- Wireless remote operation
- Stable crawler movement
- High sludge pumping capacity
- Continuous daily operation
- Easy transportation between sites
- Reliable hydraulic performance
- Simple maintenance procedures
The customer also emphasized workplace safety. Maintenance activities followed confined-space procedures similar to internationally recognized practices such as ISO 45001 Occupational Health and Safety Management Systems. Reducing worker exposure inside sludge tanks remained one of the company’s highest priorities. The engineering team therefore preferred robotic cleaning equipment capable of completing most maintenance tasks remotely.
Daily productivity represented another important consideration. Existing cleaning methods often required several days to complete one sedimentation tank. Management hoped automated equipment would shorten maintenance shutdowns while allowing technicians to supervise operations from outside hazardous areas.
After evaluating every operating condition, YG Machinery recommended the YG900 Dredging Robot. The model offered sufficient pumping capacity, wide cleaning coverage, wireless remote control, and excellent mobility for industrial sludge removal projects across multiple treatment facilities.
Why The Customer Selected The Remote Control Dredging Robot
Following the engineering consultation, YG Machinery prepared a detailed technical proposal comparing the YG700, YG800, YG900, and YG1200 models. Instead of recommending the largest available machine, our engineers focused on balancing cleaning efficiency, transportation convenience, operating cost, and future project expansion.
The customer initially considered the YG700 because it offered lower investment costs. However, several maintenance contracts involved large sedimentation tanks where higher pumping capacity would significantly reduce cleaning time. After reviewing projected workloads, management agreed that investing in a larger model would improve long-term operating efficiency.
The YG900 ultimately became the preferred solution because it matched both current maintenance requirements and future expansion plans.
Several technical advantages influenced the final purchasing decision.
- 900 mm dredging width
- 200 m³/h pumping capacity
- 22 kW main motor
- Wireless remote control
- Underwater LED lighting
- 50 mm particle handling capacity
- Four-inch discharge system
- Stable crawler drive system
The customer particularly appreciated the wireless operating system. Operators could control the robot from outside the tank while maintaining clear visibility through inspection openings and camera monitoring. Compared with manual cleaning, remote operation greatly reduced confined-space entry while improving overall operational safety.
Another important advantage involved transport flexibility. The compact hydraulic station and crawler robot could be moved between different wastewater plants without requiring specialized transportation equipment. This flexibility allowed one machine to support multiple maintenance contracts throughout the year.

Since the robot had already passed comprehensive factory testing, commissioning focused mainly on hydraulic connections, electrical inspection, wireless controller pairing, and operational verification.
YG Machinery provided remote technical guidance throughout the installation process. Engineers assisted the customer with hydraulic hose connections, winch installation, controller calibration, pump inspection, and emergency stop verification. Each subsystem was tested individually before the complete machine entered trial operation.
Operator training emphasized practical field operation rather than classroom instruction. Most maintenance technicians already possessed experience with hydraulic equipment, allowing them to become familiar with the robot within a short period.
Training covered the following topics.
- Wireless remote operation
- Hydraulic system inspection
- Daily maintenance procedures
- Sludge pump servicing
- Crawler track inspection
- Emergency shutdown procedures
