What should I do if my Dolphin gets stuck on the drain?
Short answer: Turn off the pool filter system during your Dolphin's cleaning cycle, since suction from the main drain can hold the robot in place.
Try running your Dolphin with the pool filter system off for the entire cleaning cycle to reduce suction from the main drain.

The fix
Step by step.
If your Dolphin gets caught on the pool drain and cannot free itself, try these steps in order.
-
Step 1Turn off the pool filter system
Keep the pool filter system off for your Dolphin's full cleaning cycle. Extra suction from the main drain can hold the robot in place.
-
Step 2Consider a drain-assist device
Aftermarket drain-assist devices attach to the main drain cover and can help keep your Dolphin from getting stuck. You can find these devices by searching online.
-
Step 3Adjust the handle, if equipped
If your Dolphin has an adjustable handle, move it to the farthest slot toward the front. This can help the robot get over the drain.
