Double-check before purchasing

  • Model compatibility varies — confirm your specific Dolphin model number before ordering an ultra-fine replacement basket

Compatibility

Dolphin ultra-fine filter baskets are available for multiple Dolphin pool robot models Confirm your Dolphin model is listed as compatible before purchasing. The ultra-fine mesh captures finer particles — algae, fine sand, and dust — that standard fine-mesh baskets miss. Verify your specific model number when ordering.

How to Verify Fit

  • Ultra-fine mesh appears denser than standard fine mesh — hold both up to light to see the difference
  • Basket must click into your model's top-load panel using the same latching mechanism as the standard basket
  • Check that the basket frame dimensions match your current basket — ultra-fine and fine baskets for the same model are usually the same frame size

Common Mistakes to Avoid

  • Assuming all ultra-fine baskets are interchangeable across Dolphin models — sizes differ between the E series (above-ground) and M series (in-ground)
  • Not cleaning the ultra-fine basket more frequently — finer mesh clogs faster than standard mesh and must be rinsed every cycle
  • Switching to ultra-fine when your pool mainly has large debris — the basket will clog very quickly and suction will drop

When to Replace

Clean after every cleaning cycle (more frequently than fine mesh). Replace when mesh tears — which can happen sooner than with coarser mesh due to higher debris load per pore.

Buying Tips

Ultra-fine filter baskets cost slightly more than standard baskets. They are worth it for pools prone to algae, fine sediment, or dust. Maytronics sells OEM versions; third-party compatible options are available but quality varies more than with standard baskets.

Frequently Asked Questions

Should I use a fine or ultra-fine filter basket for my Dolphin?

Use fine mesh for pools with mostly leaves and large debris. Use ultra-fine for pools with algae, fine sand, dust, or cloudy water issues.

Can I switch between fine and ultra-fine baskets on the same robot?

Yes — both basket types use the same frame design for a given model. You can swap between them depending on pool conditions.

Do ultra-fine filter baskets reduce cleaning performance?

Not when clean. A clogged ultra-fine basket reduces suction significantly, so more frequent rinsing is essential.
