Filtration is rated in microns (µm — millionths of a meter): the smallest particle the filter reliably traps, so a lower number is a finer filter. A human hair is ~70 µm; ultra-fine (~3–10 µm) catches the silt and dead algae that make water hazy. "µm not published" means the maker states no number — which is information in itself.
Pros
- From Maytronics/Dolphin — the most established, reliable name in pool robots, with no battery-fire recall history
- Cleans floor, walls, and waterline; magnetic-connect charging and easy Click-Up removal
- The simplest of the three to live with; 2-year warranty
Cons
- No surface skimming, and a shorter 2.5-hour cleaning cycle
- Costs more than the robot that beats it on every one of those counts
- Sold brand-direct rather than on Amazon, so there is no independent owner base to check — the only rating that exists is Maytronics' own, from 26 reviews, and a maker's page runs about a star high
- Best for medium pools (up to 33 ft) — not the largest backyards
- Less smart navigation than the camera/ultrasonic flagships
“Maytronics dominates the market with its Dolphin robots, recognized for their reliability and solid after-sales service.”— Pool Planet

- — The Amazon rating was retired: two signed-in searches found no Liberty 300 listing on Amazon at all, so a 3.7★/97 we could not re-pull was deleted. The only rating now shown is the maker's own 3.9★ across 26, labelled as brand-hosted.
