A retractable garden hose reel is a device that stores and organizes a garden hose efficiently. It typically consists of a spool or drum that winds the hose around it, with some models featuring an automatic rewind system to make winding the hose easier. The reel can be wall-mounted or free-standing, allowing for easy access and storage of the hose when not in use. Additionally, many retractable garden hose reels come with adjustable nozzles and other features to make watering your garden more convenient.
