The fix
Step by step.

-
Stretch the cable in the sun. Take your Dolphin out of the pool. Stretch the cable out in the sun for at least 3 hours to help remove kinks and twists.
-
Check the water conditions. After straightening the cable, keep the water temperature above 59°F and pool chemicals within Maytronics' recommended usage range to help prevent tangles. Pool chemical information

-
Limit the amount of cable you use. Avoiding excess cable is the most important step for preventing tangles. This matters whether your Dolphin has a swivel or not, especially if it does not. Measure out a cable length equal to the longest length of your pool. That is the amount your robot needs.
-
Position the power supply. Place it near the middle of the pool's longest side, several feet back from the edge. This lets the blue cable enter the water in a straight, relaxed line. It also helps keep tension even as the robot moves and allows the swivel, if equipped, to turn freely.
-
Loosely coil the extra cable. As you place the robot in the pool, leave the excess blue cable in loose coils at the pool's edge. This helps the cable feed into the water naturally as the cleaner moves.
-
Wind the cable properly after use. Pay attention to how you wind the cable after each cleaning cycle to help keep it free of tangles.
-
Check the wheels or tracks. Look for anything blocking their movement. An obstruction can make your Dolphin travel in circles and twist its cable. See how to clean the tracks.
