In early 2025, a lake maintenance contractor in Valencia, Spain, officially purchased a dredging robot from YG for lake cleaning to remove years of accumulated silt, debris, and algae from urban park lakes. He told us that traditional manual dredging is not only costly and time-consuming, but also requires underwater operations, posing significant safety risks. After a week of trial use of YG’s underwater dredging robot, he reported: “The dredging efficiency is more than three times faster than manual dredging, the water flow has significantly improved, and the management department is very satisfied.”
This case resonated with other clients in the industry in the region. In recent years, many urban lakes, park water features, vineyard irrigation lakes and reservoirs in Spain have faced problems such as silt accumulation affecting water quality, reducing water storage capacity, and increasing maintenance difficulty. Moreover, European environmental departments are increasingly emphasizing the ecological restoration of aquatic bodies. Therefore, more and more clients are seeking efficient equipment like the Crawler Dredging Robot, which can replace traditional excavators and manual diving operations.

Why Spanish Customers Prefer YG Dredging Robot for Lake Cleaning?
- Highly Efficient, Safe, and No Water Submersion Required
YG’s Remote Control Dredging Robot features a fully enclosed design, allowing it to operate in lakes, reservoirs, and sedimentation tanks without requiring manual intervention in the water, significantly reducing construction risks.
- Powerful Pumping System Adapts to Common Lake Mud Textures in Spain
Southern Spanish lakes have high sand content in their silt, while northern lakes contain more humus. YG equipment is equipped with a powerful mud pump, suitable for various water body mud structures.
- Crawler Dredging Robot Offers Enhanced Mobility
The tracked structure allows for easy movement on the lakebed without getting stuck in silt, making it suitable for long-neglected natural lakes, artificial lakes, and agricultural irrigation ponds.
- Remote Control Enhances Operational Safety
European customers are highly concerned about equipment safety. YG’s Remote Control Dredging Robot can operate over 200 meters, allowing construction personnel to complete dredging operations from the shore.
YG’s Solution (Spain Project Record)
During our communication with the client, we provided a complete water dredging solution based on the lake’s area, silt thickness, and bottom structure:
- Using a dredging robot for lake cleaning to extract bottom sediment.
- Equipped with a 30-meter sludge discharge pipe, the silt was pumped to a temporary pond on the shore.
- Solid-liquid separation was achieved using flocculation.
- Finally, a solid sludge cake was transported out, meeting environmental protection requirements.
The entire project was completed in just two weeks, saving half the time compared to traditional construction methods.
After the project’s completion, the client purchased a second underwater dredging robot for dredging nearby agricultural irrigation canals. In addition, customers in other European countries, such as France and Poland, have also reported very positive results after using YG dredging robots.
Typical Needs of Spanish Customers
Based on feedback from several Spanish customers, we have summarized the common needs in the region:
- They do not want to invest in expensive manual diving.
- They need low-noise equipment to avoid disturbing nearby residents.
- They require equipment that is easy to maintain and operate.
- They want to shorten construction cycles and improve the efficiency of seasonal projects.
- They are more concerned about environmental emission requirements.
YG’s dredging robot fully meets these needs and has been applied in parks, lakes, seaside saltwater pools, and farmland irrigation ponds in many parts of Spain.
