Dolphin nautilus cc plus filter basket

dolphinnautilus ccfilter

Double-check before purchasing

  • Nautilus CC Plus and M-series part interchangeability depends on production year — always verify before cross-model purchasing

Compatibility

The Dolphin Nautilus CC Plus uses two cartridge filter baskets in a top-load housing. Both fine-mesh and ultra-fine-mesh baskets are available as replacements. The Nautilus CC Plus is one of Dolphin's most popular models and parts are widely stocked.

How to Verify Fit

  • The Nautilus CC Plus top-load panel houses two baskets side by side — both must be installed for normal operation
  • Each basket clicks independently into place — test both individually before closing the lid
  • Mesh should be clean and intact before each cleaning cycle

Common Mistakes to Avoid

  • Buying baskets for Dolphin models sold only in other regions — the Nautilus CC Plus is primarily a North American market model with specific part compatibility
  • Mixing mesh grades — both baskets must be the same grade (both fine or both ultra-fine)
  • Leaving baskets in the robot between cleaning sessions — store dry baskets outside the robot or in an open position to prevent mould

When to Replace

Clean after every 1–2 cycles. Replace the pair annually or when mesh damage occurs.

Buying Tips

The Nautilus CC Plus is widely sold through Costco and pool retailers in North America. Replacement filter baskets are stocked on Amazon, at Leslie's Pool Supply, and through Maytronics directly. OEM is safest; well-reviewed third-party options are plentiful.

Frequently Asked Questions

Is the Dolphin Nautilus CC Plus the same as an M-series robot?

The Nautilus CC Plus shares hardware with some Maytronics in-ground models but is sold under the Nautilus CC Plus name in North America. Parts may overlap with certain M-series variants — confirm part numbers before cross-purchasing.

Where is the filter basket on the Dolphin Nautilus CC Plus?

Inside the top-load access panel on top of the robot. Flip the robot right-side-up, lift the panel, and both baskets are visible.

How do I know if I need fine or ultra-fine filter baskets for the Nautilus CC Plus?

Use fine mesh for typical debris (leaves, sticks, insects). Use ultra-fine if your pool has algae blooms, fine sand, or persistently cloudy water.
