This Robot Shark Gobbles Up Rubbish From the Water

It travels up to 5km on a single charge of its batteries and swallows up to 500kg of plastic and other trash along the way. WasteShark can operate on inland waterways or in coastal waters. It also removes biomass such as algae or weeds as these can be harmful to aquatic ecosystems if left unchecked. WasteShark was invented by Dutch firm RanMarine. It comes in 2 versions, one is remote-controlled, the other is autonomous.
