Remove stored memory
A tightly wound cable can retain a coil. With power disconnected, unwind the full usable length and lay it straight. Let it relax naturally; do not heat it artificially, stretch it with weights, or bend it sharply in the opposite direction.
Use the right amount
Too little cable restricts coverage and strains connections. Too much creates loops the cleaner can cross. Measure the route from the supply side to the farthest pool point, then release the amount needed for free travel plus reasonable slack.
Feed without twists
Walk the cable toward the water while allowing it to lie in its natural orientation. Do not flip coils over the coping. If the robot repeatedly rotates one way, inspect navigation, obstacles, brushes, and tracks rather than accepting growing twists.
Store it correctly
After rinsing and drying as directed, coil the cable in broad, loose loops on the caddy or approved storage point. Avoid tight figure-eight bends unless the manufacturer recommends them. Keep the cable shaded and protected from traffic, chemicals, and sharp edges.
Inspect the swivel and drive
A swivel can reduce twisting but cannot fix every route or obstacle problem. Make sure it rotates freely without forcing it. Uneven brush or track wear, trapped debris, and a blocked impeller can alter movement and contribute to repeated tangling.

Frequently asked questions
Should all of the cable go in the pool?
No. Put in enough for full coverage without tension. Keep unnecessary length organized outside the water according to the manual.
Can I untangle the cable while the robot is running?
No. Turn the system off and disconnect power first. Keep swimmers out while a corded cleaner is connected or operating.
Why does a new cable keep coiling?
Packaging and storage can leave temporary cable memory. Fully unwind it, lay it straight, and use broad loops for storage. Contact support if it remains kinked or shows damage.
Final decision
Match the answer above to the exact model manual, pool measurements and maintenance routine. Amazon listings can change by seller, bundle and generation, so verify the product name and ASIN before relying on a feature.
