The Ocean Cleanup is gathering floating garbage, and Clean Up the Lake is collected submerged garbage. An organization called 4ocean also gathers waterborne trash, and is now using a robot to clean the beaches adjoining the water.

The remote-controlled BeBot Beach Cleaning Robot, created in collaboration with Searial Cleaners and Poralu Marine, has WALL-E's tracks and a sifting mechanism similar to equipment you'd see on a farm.

It can hold up to 100 liters of waste, to be dumped and sifted through by workers.
