Non-Return Flap for Dolphin S200 / S300i Robotic Cleaner

The non-return flap is a small but functionally crucial part of the Dolphin S200 and S300i robotic pool cleaners. Its task is to prevent the debris sucked into the filter basket from returning to the water when the cleaner moves or turns.

Wear or deformation of the flap manifests itself in a significant reduction in cleaning efficiency – the cleaner leaves streaks of dirt behind it. Replacement with an original part immediately restores correct operation without the need for service intervention on the other components.

Installation is simple: just remove the filter basket, dismantle the old flap and fit the new one. We recommend checking the flap and, if necessary, replacing it at the start of each season. The part is compatible exclusively with the Dolphin S200 and S300i models.
