Product details

Maytronics 9991466-R4 is the ultra fine filter kit for a range of Dolphin robotic pool cleaners. The cartridges are the accordion style, and the ultra fine grade is the one to reach for when the pool is holding fine debris rather than leaves.

Fitment

Maytronics lists this kit for the S50, Active 10, Echo, Escape, E10, Saturn, Cayman, Prowler, 910 Encore and Nautilus CC. Check your model against that list before ordering, since Dolphin cartridge shapes differ between families.

Why cartridges get replaced

Filter media is a consumable. Rinsing after each run keeps a cartridge working for a long time, but pleats eventually stay grey no matter how they are washed, and the media tears at the folds. At that point the cleaner still drives its pattern but stops holding what it picks up, which owners often mistake for a suction or motor problem.

Questions and answers

What people ask about this product, answered by our pool techs.

Which cleaners take these filters?
Maytronics lists them for the Dolphin S50, Active 10, Echo, Escape, E10, Saturn, Cayman, Prowler, 910 Encore and Nautilus CC.
What does ultra fine mean?
It is the ultra fine grade of the cartridge, made to catch finer debris than a coarser filter would hold.
How many cartridges are in the kit?
It is sold as Maytronics kit 9991466-R4. The listing does not state a piece count, so check the kit against the number of cartridges your cleaner takes.
When should the cartridges be replaced?
Rinse them after every run, and replace them once the pleats stay dirty after cleaning or the media tears. A loaded cartridge starves the cleaner of flow.
