Not all robotic pool cleaners are built the same. These are the machines we'd put in a pool for Fine Dirt — 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 for Fine Dirt, 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.
Fine dirt is the opposite problem from leaves: the particles are so small that a standard filter lets them pass straight through, leaving a cloudy haze or a dusty film on the floor. Winning here is all about filter fineness.
The single most important spec for fine dirt is the filter's micron rating. Dolphin's Gen-2 NanoFilters trap particles down to a few microns — far finer than standard cartridges — so silt and dirt stay captured instead of blowing back into the water. Pair that with consistent floor coverage so the robot actually passes over every square foot.
Because we've tested the full field, these are the specific robots we recommend for Fine Dirt. All are Dolphin models — the brand that keeps winning head-to-head.

Almost always because the filter is too coarse. Upgrading to Dolphin NanoFilters, or choosing a model that includes them (like the Quantum), captures the fine dirt that standard cartridges let slip back into the water.
Standard filters catch roughly 40–150 microns; Dolphin NanoFilters go down to about 2 microns. For fine dirt and silt, the finer the better.
They fill sooner in a dirty pool, but they rinse clean in seconds. The trade-off is well worth crystal-clear water.
