The Bull — Underwater ROV (Remotely Operated Vehicle)

Manufacturer: Gerotto Robotics (Italy)

Description

The Bull is a specialized underwater robot (ROV) designed for sludge, debris, and sediment removal in submerged environments where human access is impractical or unsafe. It is engineered for confined spaces, allowing operation in narrow basins, tanks, cooling systems, lagoons, drainage pipes, and underground water systems.

Because The Bull works fully submerged, it can clean in-place without requiring the emptying of tanks or plant shutdowns. This minimizes operational disruption, reduces water handling, and cuts maintenance downtime.

Its design minimizes the mixing of surrounding water and sludge during vacuuming, improving the efficiency of sludge extraction. The system integrates cameras, LED lighting, dredging pumps, and optional auger brushes for optimal performance.

Key Features & Capabilities

Underwater operation / submerged use – can work completely underwater without the need for divers.

Confined-space compatible – operable in tight or narrow areas where human entry is impossible.

Non-intrusive cleaning – performs cleaning without emptying tanks or stopping plant operations.

Reduced mixing – designed to limit disturbance to surrounding water, improving suction efficiency.

Dredging pump module – enables suction of sludge and sediment on flat, submerged surfaces.

Camera + LED lighting – integrated underwater visibility for accurate control.

Auger brush accessory – front-mounted brush helps feed heavy sludge into the suction line.

Remote control options:
• Remote Control Kit Pro – electro-hydraulic distributor with proportional, compensated control.
• Remote Control Smart Kit – onboard proportional controls with lightweight umbilicals (4 hydraulic + 1 electric).

Modular and configurable – available with multiple accessories such as tracks, augers, brushed drums, or stainless-steel augers.

Applications

Sludge and sediment removal in lagoons, basins, and water treatment plants

Cleaning of underground drainage systems and sewers

Maintenance of industrial cooling basins and chemical plant tanks

Safe operation in confined or hazardous submerged environments where diver entry is restricted
