But in some cases this is.
Dolphin pool cleaner gets stuck on main drain.
I have a dolphin deluxe 4 pool cleaner that gets stuck on the pool drain i shut the drain off and it still gets hung up on the drain.
In fact a pool cleaner interacting with a pool drain that gets stuck in one pool may not get stuck in another pool with exactly the same combination of pool cleaner and drain cover.
Try turning your pool pump off while your dolphin is in operation.
The main drain should have a lever on the pipe allowing you to close it entirely or partially close it which will reduce the suction.
The additional suction from the main drain may contribute to your dolphin getting stuck.
Depending on your model there may be a solution to this problem available from maytronics in the form of a replacement impeller cover.
Is there a part.
Alternately you can adjust the main drain pressure by location the controls at the pump.
Only a slight variation in the angle of the pool bottom relative to the pool drain can cause the pool cleaner to get stuck.
