Product details

The Maytronics 9991047-ASSY is the cartridge filter door assembly for the Dolphin M400, M500, Supreme M4, Supreme M5 and Liberty robotic pool cleaners. It is the genuine Maytronics part, supplied as the complete door assembly.

Why it matters

The filter door is opened every time the cartridges are cleaned, and over a few seasons the hinge and latch wear. A door that has cracked, warped or no longer latches lets debris bypass the cartridges, so the cleaner runs its full cycle and still leaves the floor dirty.

Replacing it

Fitting the new door is a quick job that most owners can do at home with the cleaner on the deck, and it puts an otherwise healthy robot back to full performance.

Questions and answers

Which Dolphin cleaners use this filter door?
The Dolphin M400 and M500, the Supreme M4 and M5, and the Liberty.
Why would I need to replace it?
The filter door takes wear every time the cartridges come out. Once it cracks, warps or will not latch, debris can slip past the filters and the cleaner stops picking up as well as it should.

Yes. It is Maytronics part number 9991047-ASSY.
Can I fit it myself?
Yes. Replacing the door assembly is a simple job most owners can do at home.
