Product details

The Maytronics 9991458-ASSY is the ultra fine cartridge filter basket assembly for Dolphin robotic pool cleaners. It is the genuine Maytronics part, supplied assembled and ready to drop into the cleaner.

Which cleaners

Maytronics lists it across a long run of models: E30, Prowler 920 and 930w, Discovery M2big, Triton PS, Active 20, Active 30 and Active 30i, Advantage Ultra, the Pentair Warrior SE and Warrior Si, Premium, Proteus Dx5i, T35, T45, T55i, S200, S300 and S300i, Mercury and Quantum.

Why the ultra fine version

The basket is the whole point of a robotic cleaner. Ultra fine cartridge media traps the small particles that a coarse basket passes straight through, which is what leaves a pool looking clean rather than merely swept.

When to replace it

Rinse the basket after every run. Replace the assembly when the media no longer comes clean, or when the basket body has cracked or warped enough that it no longer seats properly, since a poor seal sends debris back into the pool.
