When your Dolphin is in use, only release enough of the cable for your Dolphin to properly cover your pool. Leave the excess cable loosely rolled outside of the pool. When storing your Dolphin on a caddy, carefully wrap the cable so it does not have any kinks and place it around the top of the caddy. Once a week, unplug the cable from the power supply and unwind the tangled portions of the cable, straighten it out and leave in the sun for a few hours. This will help remove any tangling or kinks. For visuals, check out this video.
