Sheco Ark-M is a water clean-up drone(e.g. robot vacuum cleaner) designed to recover pollutants from bodies of water. It uses a specialized impeller, a blade directing water flow inside, to collect water and contaminants, separating them through reusable mesh-filters. Once collected, pollutants are stored in a cartridge, while purified water is released immediately. The proprietary impeller and filter effectively collect and separate contaminants in both liquid and dust forms, including oil, ship paint, algae, and cargo dust. Its operational range is 50m with a wire and 1km wirelessly. Users can oversee and control the drone via a touch-based GCS screen.
