Industrial Tank Cleaning
Weda’s robotic cleaning systems help you clean tanks, lagoons, and reservoirs
without draining water reducing downtime, labor, and environmental impact in
one solution.
Industrial Tank Cleaning Equipment for Sludge and Sediment
When sediment builds up on a process tank floor, reaching it can be more disruptive than removing it. Draining, transferring water and preparing for personnel entry can turn a routine cleaning task into a substantial maintenance project.
WEDA Robotics manufactures remotely operated equipment for extracting sludge and sediment from submerged tank floors. Our systems support industrial facilities and cleaning contractors that need an alternative to draining suitable tanks for bottom cleaning.
The starting point is the cleaning task: what has settled, where it has accumulated and how it will be removed from the site. Explore our tank cleaning robot solutions for an overview of the equipment approach.
Submerged Cleaning Use Cases — Without Draining Water
Sludge removal
Sediment & silt extraction
Desilting tanks and lagoons
Algae and biofilm cleaning
Chemical residue removal
Pit, sewer & tunnel dredging
Micro-dredging for tight/confined areas
Confined space and no-man entry jobs
How Robotic Industrial Tank Cleaning Works
A submerged robot moves across accessible areas of the tank floor while the operator controls it from outside. Its configured suction and pumping system collects settled material and transfers sludge and water through a discharge hose.
The equipment must be able to reach the deposits and move through the working area. Access openings, internal columns, pipework, floor slopes and sumps all influence deployment and cleaning coverage.
Before work begins, the operator needs a defined cleaning route, a retrieval method and a suitable destination for the extracted material. Pump selection must account for the sludge characteristics and the discharge route, including distance and elevation.
Cleaning Without Draining the Tank
In suitable applications, water can remain in the tank during sediment extraction. This avoids emptying the whole tank simply to reach deposits on its floor.
Continued process operation is a separate decision. Intakes, moving equipment, water conditions and the effect of cleaning on the process must be assessed before work starts. Some installations may require isolation even when draining is unnecessary.
Match the Cleaning Method to the Material
Fine silt, loose sediment and pumpable sludge present different demands from compacted deposits or large debris. Equipment selection should account for particle size, solids concentration, consistency and the depth of accumulated material.
For sludge-dominated applications, our sludge removal robot solutions explain the equipment approach in more detail. For broader submerged maintenance applications, see our underwater cleaning robot overview.
When Another Cleaning Method Is Needed
Removing settled material from a tank floor has a different scope from stripping bonded scale, cleaning every wall surface or preparing a vessel for inspection or repair. Define the required result before choosing the method.
Chemical compatibility and any hazardous-area requirements also need to be established for the specific equipment and installation. Suitability for water and sediment removal should not be treated as approval for every industrial liquid or residue.
Choosing WEDA Equipment for Your Tank
YT-600 for Industrial Process Tanks
The WEDA YT-600 is designed for sediment removal and is listed for industrial process tanks and cooling tower applications. It combines an onboard pump with a 630 mm cleaning width and remote control with camera integration.
It is a relevant starting point for assessing submerged sediment extraction from accessible tank floors. Confirm access dimensions, sludge conditions and discharge requirements before selecting the configuration.
YT-800 for Larger Sediment Removal Projects
The WEDA YT-800 is designed for larger industrial sediment removal and dredging applications. It is an option to assess for reservoirs, ponds and sediment basins where the scale of the work calls for a larger platform.
Tank size alone does not determine the choice. The volume and characteristics of the deposits, access restrictions and required removal rate must be considered together.
VR-600 for Large Water Reservoirs
The WEDA VR-600 is designed for remotely operated cleaning in large reservoirs and water towers. It provides another option where the application centres on water storage rather than an industrial sediment basin.
WEDA can assess these requirements with your operations or maintenance team before recommending equipment.

What Determines Tank Cleaning Time and Cost?
A useful estimate starts with the material to be removed and the conditions surrounding the job. Floor area alone cannot establish cleaning time.
Provide tank drawings or photographs, access dimensions, water depth and an estimate of sediment thickness. Describe the material, identify obstructions and specify where the extracted sludge needs to go.
The full cost assessment should include deployment, cleaning, sludge handling, retrieval and equipment maintenance. When comparing robotic cleaning with your existing method, also include any water transfer, refill, entry preparation and process interruption involved.
This gives the comparison a practical basis without assuming a fixed saving for every tank.
Reducing the Need for Personnel Entry
Remote operation allows suitable floor-cleaning work to be performed with the operator outside the tank. For facilities reviewing entry-dependent maintenance tasks, our confined space cleaning robot guide explains this application.
A robotic cleaning plan still needs to address deployment, electrical equipment, moving machinery and recovery if the machine becomes obstructed. If personnel entry is required for any part of the project, applicable entry procedures remain necessary.
For US facilities, OSHA’s permit-required confined space standard sets out requirements for spaces and activities within its scope.
FAQ – Industrial Tank Cleaning
Can industrial tank cleaning be performed without draining?
Yes, in suitable applications. Submerged robots can extract settled sludge and sediment while water remains in the tank. Access, liquid conditions, residue characteristics and discharge arrangements determine whether the method is appropriate.
Can the tank remain operational during robotic cleaning?
Sometimes, but keeping water in the tank does not automatically mean the process can continue. Intakes, moving equipment and the potential effect on operations need a site-specific assessment.
Which WEDA robot should I consider?
The YT-600 is relevant to industrial process tanks and sediment removal. The YT-800 is intended for larger sediment removal projects, while the VR-600 addresses large water reservoirs. Final selection depends on access, material and operating conditions.
Does WEDA supply industrial tank cleaning equipment?
Yes. WEDA Robotics manufactures submerged cleaning equipment for facility operators and cleaning contractors. The team can help assess the application and select a suitable system.
