Abstract
The present invention describes a water surface maintenance and cleaning system which comprises a home base station and a plurality of cleaning robot. The home station is either fixed on the water bank or floating on the water surface as an island. The home station serves as a charging station and trash collection station. The home base station is covered with solar PV panels and the PV panels convert the sunlight into electricity and then store the electricity into the batteries. The self-driving cleaning robot boat, which floats on water surface and drives around and sweeps the water surface. While sweeping across the water surface, the robot boat which is equipped with motor, rotors, pumps, nets, containers, etc. can intake water and filter out trashes and any other environmental unfriendly substances such as plastic bottles, cans, leaves, algae, plants, bio-films, and oil/grease.
