Before you order
How Dolphin filters work and wear.
When checking a filter for wear, look for torn material, cracked baskets or lids, and damaged fittings. This category includes coarse mesh bags, fine filters and ultra-fine filters, plus assemblies and smaller parts such as clips and flaps. Check the filter type and what the listing includes before choosing a replacement.
Start with your robot's exact model, not the filter's appearance. Each part page lists the robots it fits, and each robot has its own parts page. Compare the part number on your old part with the replacement listing. Similar names do not confirm a match, and pack size matters when ordering bags or clips.
