Product details

The Maytronics 9980891 is the non return flap for a range of Dolphin robotic pool cleaners. It sits at the intake and works as a one way door: open while the pump pulls water through, closed when the cleaner stops so the debris it collected stays in the filter instead of drifting back out.

When to replace it

A flap that is cracked, warped or missing lets leaves and grit fall out of the robot when the cycle ends or when you lift it from the water. If you are finding debris back in the pool after a run, this small part is the first thing to check.

Compatibility

Fits the Dolphin Triton Plus, Supreme M4, Supreme M5, Supreme M5 Bio PVC, C3, C3 Dynamic, C4, M400 and Oasis Z5. Sold as a single flap.
