Underwater Cleaning Robot

Manual underwater cleaning slows operations, adds risk, and drives up costs. Our robotic approach standardizes the process, shortens cycles, and minimizes exposure—so critical assets return to service faster at a lower total cost.

For demanding underwater cleaning in reservoirs and large tanks, the Weda B-600 delivers heavy-duty throughput and no-entry safety, removing sludge and sediment efficiently.

The Cost of Manual Underwater Cleaning

Diver-based cleaning introduces safety concerns, variable results, and unpredictable timelines. Weather and visibility add operational uncertainty, while staffing specialized crews increases OPEX.

  • Extended downtime from slow, manual cycles
  • Safety exposure for personnel and third-party divers
  • Inconsistent quality and rework risk
  • Scheduling variability due to conditions on site

Robotic, No-Diver Cleaning

The Underwater Cleaning Robot operates remotely, delivering consistent coverage on submerged surfaces without human entry. The result is safer execution, predictable timelines, and reliable outcomes.

  • No divers required: reduce risk and logistics
  • Remote operation: precise, repeatable cleaning
  • Built for harsh conditions: reliable, industrial-grade design

Procurement-Ready ROI

Fewer on-site specialists and faster cycle times reduce OPEX while increasing asset availability. Predictable results simplify planning and budgeting.

  • Less downtime—more productive hours per year
  • Lower labor cost—no specialized dive teams
  • Improved safety metrics and potential insurance benefits
  • Consistent results that reduce rework

Technical Highlights

Designed for continuous use and easy integration into existing maintenance workflows.

  • Remote-controlled, no-entry cleaning
  • Stable operation in low-visibility conditions
  • Compatible with common industrial safety practices
