The WasteShark+ is a remote-controlled, zero-emission surface vessel designed to efficiently remove floating waste, biomass, and hydrocarbons from harbours, marinas, ports, and inland waterways. Powered by advanced rim-drive propulsion and a 48V lithium-ion battery system, it delivers up to 8 hours of continuous operation with enhanced thrust and reliability for daily cleaning cycles.

With a 160-litre collection basket, HD camera system, and intuitive 7” waterproof remote control, the WasteShark+ enables safe, onshore operation with minimal training required. Its robust design, long-range connectivity, and high collection capacity make it an effective and scalable solution for organisations committed to improving water quality and protecting marine ecosystems.

The WasteShark+ Pro is an advanced autonomous surface vessel designed to keep ports, marinas, and inland waterways clean — efficiently and emission-free.

This next-generation aquadrone uses LiDAR-based navigation and high-power rimless thrusters to autonomously collect floating waste, weeds, and debris with precision. With up to 8 hours of operation and a 160-litre collection capacity, it delivers reliable, high-performance environmental management with minimal operator input.

Routes are pre-programmed via the cloud-based portal, allowing the vessel to clean defined areas, avoid obstacles, and automatically return to base when complete.

The MegaShark is a high-capacity, industrial-grade cleaning vessel built in the Netherlands and designed for demanding marine environments. With a payload of up to 440kg and a large open-mouth intake capable of collecting dense biomass, industrial debris, and large plastics, it enables operators to clear substantial harbour areas efficiently while reducing unloading frequency.

Powered by dual electric rim-drive thrusters, the MegaShark offers exceptional manoeuvrability, including tight turning and on-the-spot rotation. It can be operated either manned onboard or remotely, allowing safe deployment in hazardous or restricted areas.

Running on a marine-engineered Cleantron battery system, the MegaShark delivers zero local emissions, near-silent operation, and up to 6 hours of standard runtime (with extended battery upgrades available). Custom deck layouts, thruster upgrades, water quality sensors, and trailer options allow the vessel to be tailored to your operational requirements.

The CyanoShark — the world’s first autonomous vessel designed to detect, capture, and neutralise harmful blue-green algae at the source.

Using patented Staged Flow Treatment System (SFTS) technology, the CyanoShark combines UVC, ultrasound and ozone in a completely chemical-free process. This ensures effective treatment of harmful algal blooms without damaging surrounding ecosystems or causing toxin “shock” release.

With LiDAR, GPS and 4G connectivity, the CyanoShark operates fully autonomously or under manual control, delivering real-time monitoring, precise route coverage, and integrated water-quality data. Capable of treating up to 2,100m² per hour, it offers a scalable, environmentally responsible solution for marinas, ports, reservoirs and inland waterways.
