Clogged pipelines cause flooding, health hazards, and costly downtime. A robotic dredge removes sediment, debris, and buildup without manual entry. YG Machinery offers six models that handle pipes and channels from 500 to 1,200 mm in width. Each unit runs on wireless remote control with underwater LED lights. This keeps operators safe in confined or hazardous spaces. Below you will find full specs, working principles, and real-world use cases.
The table below shows the full range of our robotic dredge lineup. Each model targets a different pipe or channel size.

All models share the same hydraulic system platform. The hydraulic station measures 2200×1200×1700 mm (YG-500 to YG-900) or 2120×1240×1200 mm (YG-1200). Each unit comes with a wireless remote controller, 50-meter hydraulic hoses, and dual underwater LED lights. The reeling system runs at 0–10 r/min for smooth cable management.
A robotic dredge operates through a simple but effective process. The operator stays above ground at all times.
Deployment: The robot is lowered into the pipe or channel through a manhole or access point. Tracks grip the surface for stable movement. A winch or crane handles the lowering.
Inspection: Underwater LED lights illuminate the work area. The operator uses the wireless remote to guide the robot forward. Track speed adjusts from 3 to 15 m/s.
Dredging: The pump sucks up sediment, sludge, and debris. The pump flow reaches 100–200 m³/h depending on the model. Material is discharged through the outlet pipe to the surface.
Repeat Passes: The robot moves forward and back to clean the full pipe length. The operator monitors progress on the surface.
The entire process requires no confined-space entry. This removes the biggest safety risk in traditional dredging methods.
What Makes a Modern Robotic Dredge Different From Manual Cleaning?
Operator Safety
Manual pipeline cleaning sends workers into toxic, low-oxygen environments. A robotic dredge removes that risk entirely. The operator controls everything from the surface. No entry into confined spaces is needed.
Faster Cleaning Speed
Track travel at up to 15 m/s covers long pipe sections quickly. Pump flow of 100–200 m³/h moves material out fast. A single pass clears most blockages. Manual methods take far longer for the same result.
Handles Tough Debris
The pump passes particles up to 60 mm on the YG-1200 model. Sand, gravel, roots, and hardened sludge all get sucked up. Smaller models handle particles up to 15–38 mm for lighter jobs. The wide track design keeps the robot stable even under heavy load.
Works in Tight Spaces
The smallest model (YG-500) is only 1500×500×650 mm. It fits through standard manholes easily. The compact track design allows turning in confined pipe networks. No extra disassembly is needed for transport or deployment.
Industrial Dredging Robot for Heavy-Duty Applications
An industrial dredging robot handles conditions that manual teams cannot. Here are common heavy-duty use cases:
Municipal Sewer Systems: Removing years of grease, sand, and root buildup from city sewer lines.
Storm Drain Cleaning: Clearing flood-prone drains before the rainy season.
Industrial Pipelines: Cleaning process lines in chemical plants, food factories, and mines.
Pump Station Intakes: Removing debris that reduces pump efficiency.
River and Canal Maintenance: Shallow waterway dredging for flood control and irrigation.
Power Plant Cooling Lines: Clearing sediment from large-diameter cooling water pipes.
Each job benefits from the remote operation and high-capacity pumping. This type of robot reduces both labor cost and project time.
Sewer Cleaning Robot for Sale – How to Choose the Right Model
Buyers looking for a sewer cleaning robot for sale should match the model to their pipe sizes. Here is a quick guide:
YG-500 / YG-600: Best for small sewer branches and residential lines. Compact size, 22 kW motor.
YG-700 / YG-800: Ideal for main trunk sewers and medium industrial pipes. 30 kW motor, 38 mm particle handling.
YG-900 / YG-1200: Built for large channels, storm drains, and heavy sediment. 30–45 kW motor, up to 60 mm particles.
A pipeline cleaning robot manufacturer like YG Machinery can also customize hose length, pump type, or track width for special projects. Contact us with your pipe dimensions and debris type for a tailored recommendation.
Frequently Asked Questions About Underground Robotic Dredges
How deep can the robot operate?
The robot works in water up to its full body height. The YG-500 handles water depth up to 650 mm. Deeper submersion is possible with extended hydraulic hoses. The standard hose length is 50 meters.
Does the robot work in curved pipes?
Yes. The tracked design allows the robot to navigate gentle curves. Sharp bends may require the smaller models for better maneuverability. The YG-500 and YG-600 handle tight bends best.
What power source does it need?
All models run on a hydraulic power station. The station connects to a standard 380V electrical supply. No onboard engine or battery is needed.
How do I transport the robot to the site?
The robot and hydraulic station are loaded onto a standard truck. Most models fit through a double-door van. Setup at the job site takes about 15 minutes.
What maintenance does it require?
Flush the pump with clean water after each job. Grease track rollers weekly. Check hydraulic hoses monthly for wear. Replace seals every 500 operating hours.
Every robotic dredge we build passes a 48-hour factory test. We check track movement, pump flow, remote response, and LED function. You receive a full test report before shipping. Our engineers also run a real-water test with sediment to confirm pump performance. Our service includes:
Pre-sale consultation: Share your pipe sizes and debris type. We recommend the best model.
Custom options: Extended hoses, special pump types, or wider tracks available on request.
After-sales support: On-site training, remote troubleshooting, and spare parts within 48 hours. 12-month warranty included.
