Compact access
Both use a 3-inch slurry pump and 22 kW main motor. Choose the body width around available access.
Desilting robot range
Compare the work, not just the model number
Working width is only the starting point. Pump duty, sediment, transport distance, access and power supply determine the usable configuration.

Five details make the first recommendation more accurate
- 01Sludge type and maximum particle size
- 02Working area, access width and water depth
- 03Required horizontal and vertical pumping distance
- 04Available voltage, frequency and phase
- 05Target capacity and working schedule

Industrial balance
A 4-inch pump, 200 m³/h published flow and 38 mm maximum particle size.
Higher throughput
37 kW main motors and up to 300 m³/h published flow for larger working areas.
Customization & optional equipment
Configure the machine around the site
Options are selected after the working conditions are reviewed. They are not automatically included in the standard machine.
Power option
Diesel-powered package
A Yunnei-engine diesel configuration is available for sites where a suitable grid power supply is unavailable or unreliable.
Cleaning option
High-pressure flushing
Water jets help loosen compacted deposits before the slurry pump removes the disturbed material.
Visibility option
Additional camera coverage
Add underwater camera coverage and a display to improve observation around the working head and machine.
Interchangeable working heads
Choose the breaking action for the material
Both heads can be changed according to the project. Photos or video of the sediment help us recommend the appropriate design.
Replaceable standard breaker head
For routine sludge agitation and breaking up softer deposits or aquatic vegetation. The head is removable so the front-end setup can be changed for a different task.
Heavy-duty breaker head
For thick, consolidated sludge, tougher aquatic vegetation and harder material such as shells. Actual suitability must be confirmed from the material condition.
Working-head selection
Choose the yellow standard breaker for routine agitation or the silver heavy-duty design for more demanding deposits. Head width and compatibility are confirmed with the robot model.
304 or 316 stainless-steel upgrade
The standard machine uses 201 stainless steel. For improved corrosion and rust resistance, relevant structures can be upgraded to 304 or 316 stainless steel according to water chemistry and operating conditions.
Wear parts & spares package
Recommended spares can be prepared for the selected model, pump and attachment to reduce avoidable downtime after delivery.
Material selection matters
304 and 316 upgrades improve corrosion resistance, but neither should be described as universally corrosion-proof. Please provide water quality, salinity, chemicals, temperature and expected service time for review.
Recommended spare-parts review
Prepare for routine wear before shipment
- Pump wear components and seals
- Hydraulic hose and connection parts
- Attachment teeth or working-head wear parts
- Filters, electrical protection components and fittings
- Model-specific maintenance consumables
