Water pressure is used to smoothly retract the hose back onto the reel in the hydropower hose reel. Allow the water to flow through the hose while you flip/pull the lever, and the hose will automatically wind itself back up using a water-propulsion mechanism. The hose is evenly wound, thanks to a built-in tracking guide. The hydropower processes cease when the hose is completely looped back up, and excess water is allowed to drain out of the hose.
