My Dolphin regularly forgets part of the pool

From Maytronics support, updated 2026-04-26, rewritten for clarity. Parts that fix it are below.

The fix

Step by step.

Ensure Proper Setup

Ensure that the cable is not twisted or bent and that it has sufficient cable length to reach the entire pool. Any excess cable should be rolled up on the caddy or laid alongside the pool.

Start the Dolphin from Different Locations

We recommend placing the robot in the area that the robot has missed from the beginning of the cycle. This can alter the robot's initial cleaning route, to enhance its efficiency.
