Product details
The Maytronics 99806252 is the Botia black impeller cover for Dolphin robotic pool cleaners. It is the genuine part, listed for the Dolphin Nautilus 115V CB with cartridge, the Triton 115V CB and the Nautilus Plus PS with weekly timer.
Why it matters
A Dolphin cleans by pulling water through its filter with an impeller, and the cover is what closes that impeller housing off. When the cover cracks, warps or is left loose after a service, the impeller draws part of its water from around the edge instead of through the filter. The cleaner still runs and still drives its pattern, but it picks up noticeably less, and owners usually suspect the filter or the motor first.
Before you order
Maytronics has revised Dolphin parts across the generations of these cleaners, so the model name on the lid is not always enough on its own. Open the cleaner and compare the cover against the one in your hand, and check the number if the old part still carries it.
