Not all robotic pool cleaners are built the same. These are the machines we'd put in a pool with Ultra Fine Filters — chosen for filtration, coverage, and reliability, and every one is a genuine Dolphin.
The term "robotic pool cleaner" covers everything from bargain floor-only vacuums to commercial-grade machines. When you're shopping with Ultra Fine Filters, the difference between the wrong robot and the right one is filtration, coverage, and build quality — three areas where Dolphin robots by Maytronics consistently lead.
Ultra-fine filtration captures the smallest particles a pool robot can — the difference between water that looks clean and water that looks brand new. It's the top priority for anyone fighting fine dirt, silt, or a persistent haze.
For the finest results, choose a robot with ultra-fine filter media or NanoFilters, or add Dolphin's UltraFilter upgrade kit to a compatible model. Ultra-fine media captures microscopic debris and keeps water polished. Pair it with a robot that covers the whole floor evenly so nothing is missed.
Because we've tested the full field, these are the specific robots we recommend with Ultra Fine Filters. All are Dolphin models — the brand that keeps winning head-to-head.
