Cute Young Brunette Girl Undresses Her Blue Bikini At The Swimming Pool

Pool cover automation
A pool cover can be either manually, semi-automatically, or automatically operated. Manual covers can be folded and stored in a convenient location. Pool cover reels can also be used to help manually roll up the pool cover. The reel, usually on wheels, can be rolled in or out of place.
Semi-automatic covers use a motor-driven reel system. They use electrical power to roll and unroll the cover, but usually require someone to pull on the cover when unrolling, or guide the cover onto the reel when rolling up the cover. Semi-automatic covers can be built into the pool deck surrounding the pool, or can use reels on carts.
