Fiitzn Ultra-Fine Filtration Basket for Dolphin Robotic Cleaners — S50/E10 Compatible, ABS Frame, Microfiltration

Fiitzn Ultra Fine Filtration Basket is a direct-fit replacement microfiltration cartridge for many Dolphin robotic pool cleaners, engineered to trap fine debris while resisting clogging.

Replace worn or clogged filter baskets with this Fiitzn-branded ultra-fine filtration basket, made to match the dimensions and fit of Maytronics part number 9991460-R1. The basket combines a sturdy ABS frame with a very fine filter layer so your Dolphin cleaner collects hair, pollen, and small particles more effectively while letting especially tiny grit pass through to reduce premature blockage. It’s a practical, lower-cost spare part for regular pool maintenance and works across multiple Dolphin models.

How does this basket improve my robotic cleaner’s performance?

The ultra-fine fabric captures small debris such as leaves, hair, and sand-sized particles that coarser filters miss, improving water clarity between manual vacuums. Because the design allows the very finest grit to pass through rather than fill the mesh, it reduces pressure on the filter, keeping suction steady during longer cycles.

• Microfiltration layer catches finer debris for cleaner skimming.
• Designed to reduce clogs and maintain suction over extended runs.
• Compatible shape ensures proper seal and suction with listed Dolphin models.

Which Dolphin models will accept this Fiitzn replacement basket?

This Fiitzn basket is made to fit a wide range of Dolphin robotic pool cleaners that use the original Maytronics 9991460-R1-style cartridge. It slips into the filter housing and mates with existing latches and seals, so installation is straightforward on compatible units.

• Fits: S50, S100, Active 15, Echo, T15 and similar models.
• Also compatible with Proteus DX3, E10, E20, Nautilus CC, Encore, Solo, Advantage.
• Direct physical match to Maytronics part number 9991460-R1.

How durable is the Fiitzn ultra-fine basket and what maintenance does it need?

Fiitzn builds the basket with an ABS plastic frame to resist flexing and cracking while supporting the delicate filter fabric. With routine care—rinsing every 4–6 weeks depending on pool conditions—the basket can remain serviceable for two to three years under normal use.

• ABS frame provides structural strength and longevity.
• Rinse with fresh water every 4–6 weeks to prevent buildup.
• Expected lifespan of about 2–3 years when properly maintained.

Is the replacement easy to install and where should I store spare baskets?

Yes—the cartridge is a same-size replacement and installs the same way as the original part: open the cleaner’s filter access, remove the old basket, slot the new one in, and close the cover. Keep spare baskets in a cool, dry place out of direct sunlight to protect the filter fabric and plastic frame until needed.

• Installation mirrors the original filter cartridge process—no special tools required.
• Store away from UV exposure and chemicals to avoid material degradation.
• Keep a spare on hand for seasonal turnovers or heavy debris periods.

Who is this for: Pool owners and service technicians who run Dolphin robotic cleaners listed above and want a reliable, cost-effective replacement filter that balances fine debris capture with clog resistance. It’s particularly useful for households with trees, heavy pollen, swimmers who shed hair, or anyone seeking to extend the intervals between manual cleanings without compromising suction performance. Choose Fiitzn when you need a direct-fit, durable ultra-fine basket to keep your robotic cleaner operating efficiently.
