We carry every Dolphin robot by Maytronics. Here are the models built to handle fine dirt best — with the filtration, brushes, and navigation that matter most for Fine Dirt.
Dolphin builds one of the widest robotic pool cleaner lineups on the market, so choosing the right one for Fine Dirt comes down to matching the robot's filter, brushes, and navigation to the job.
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.
These are the Dolphin models we recommend most for Fine Dirt, ranked for this job. Every one ships free with a 30-day trial.

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.
