Not all robotic pool cleaners are built the same. These are the machines we'd put in a pool with Nano 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 Nano 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.
NanoFilters are Dolphin's Gen-2 ultra-fine filtration, capturing particles down to just a few microns — the fine dirt, pollen, silt, and dead algae that standard filters recirculate. If you want truly clear water, this is the feature to prioritize.
Look for robots that include NanoFilters in the box rather than as a costly add-on. NanoFilters trap microscopic debris that standard cartridges miss, which is the difference between hazy and glass-clear water. They're especially valuable if you battle fine dirt, pollen, or post-shock dead algae.
Because we've tested the full field, these are the specific robots we recommend with Nano Filters. All are Dolphin models — the brand that keeps winning head-to-head.

NanoFilters are Dolphin's Gen-2 ultra-fine filters that capture debris down to a few microns — far finer than standard cartridges — for crystal-clear water. The Quantum includes them in the box.
If you deal with fine dirt, pollen, silt, or dead algae, yes. NanoFilters capture those fine particles that standard filters let pass back into the pool.
Many models are NanoFilter-compatible, so you can upgrade. Choosing a robot that includes them — the Quantum, Sigma, or Premier — saves the extra purchase.
