Match the filter to your debris: use a coarse/standard filter or leaf bag for leaves and twigs, a fine cartridge for everyday dirt, and NanoFilters for microscopic debris like algae, pollen, and sand. Robots with swappable Multi-Media filtration let you change grades as the seasons change.
Pick by debris type
- Leaves, twigs, acorns: a coarse basket or the oversized leaf bag on the Dolphin Premier — big capacity that won’t clog on bulky debris.
- Everyday dirt and grit: the standard fine cartridge that ships with most robots handles routine cleaning.
- Algae, pollen, fine sand, silt: NanoFilters™ to trap the micro-particles others miss.
Change with the seasons
Many owners run a coarse filter in fall (leaf season), then switch to NanoFilters in spring and summer (pollen and algae season). Keeping both on hand means you always have the right media loaded for the job.
The flexible option
If your debris changes a lot through the year, a robot with Multi-Media™ filtration — the Premier — lets you swap between a leaf bag, standard cartridges, and NanoFilters in seconds. It’s the most versatile filtration system Dolphin makes.
