Which Dolphin models use these baskets?
Both Maytronics product pages explicitly name the five models below. Match your cleaner’s full model label; a similar name alone does not establish fit. Check any regional or serial-number restrictions with Maytronics.

Use the part number to distinguish the two when shopping. This guide does not assign a micron rating or compare cleaning performance. A listing for replacement panels alone is not the same purchase as a basket; check exactly what the package includes.
Does this also cover the Nautilus CC Plus?
No match is established here for the Nautilus CC Plus. This table covers the Nautilus CC by its exact name. Do not transfer its basket match to a CC Plus or another variant without an explicit manufacturer source.
Clean the basket before deciding to replace it
The linked E10, Nautilus CC/Proteus DX3 and S100 manuals instruct owners to switch off and unplug the power supply before filter maintenance, and to clean the filter after each cycle before debris dries. Follow the instructions for the filter assembly in your own cleaner.
Manual references, printed page 8: E10 PDF, Nautilus CC / Proteus DX3 PDF, S100 PDF. Checked 2026-10-10. For Explorer E20, use its manual portal in the table.
Before you order
- Read the full cleaner model from its label.
- Choose the fine or ultra-fine part number, and check that the listing includes a basket rather than only panels.
- Confirm the current listing and package contents. If the model, basket or suffix differs, ask Maytronics to confirm the match.
