ماشین های چمن زنی زیر آب زباله ها را از رودخانه ها تمیز می کنند

This Aquatic Weed Harvester can gather weeds and excessive amounts of trash in waterways of all sizes.

Cleantec Infra made the machine that functions similarly like an underwater lawnmower. Its conveyer belt lowers into the water and cuts, collects, and stores the trash/weeds until it needs to be discharged. 

The Harvester is one of many ways humans are trying to battle the growing threat of sea pollution all around the world.
