Robotic pool cleaner are a relatively new invention that is making life easier for people with pools. These machines automatically clean the pool and make sure it stays clean. A robotic pool cleaner works by scanning the surface of the water to find debris and then sucking it up into a bag to remove it. They can also vacuum any dirt or debris off of the bottom of the pool, which is especially helpful if there's a lot of algae or other substances on top of the water.
