The video shows a pool cleaning machine being used to clean a swimming pool. The machine is attached to a long hose and is being maneuvered by a person who is not visible in the video. The machine is shown picking up debris from the bottom of the pool, and then the person operating the machine removes a bag from the machine and empties it into a trash can. The water in the pool is clear and blue, and the pool tiles are visible under the water. The machine appears to be effective in cleaning the pool, as it is able to pick up even small debris from the bottom.
