Dolphin Advantage
Cheapest way into corded — The cheapest corded Dolphin worth carding at about $669, and the one whose rating you should read most carefully. It climbs walls, runs an active scrubbing brush and uses a top-load filter basket, all plug-and-play on a two-hour cycle with no battery involved. The catch is the evidence rather than the machine: its Amazon listing sells the Advantage, the Advantage Ultra and the Advantage Pro under one 4.4-star rating spanning $669 to $999, so that number is not a read of the $669 machine you would actually receive.

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
- The cheapest way into a corded Dolphin at about $669 — no battery, no charging, and it runs its full cycle every time
- Climbs walls and runs an active scrubbing brush, which is more capability than most cordless machines at this price
- Top-load filter basket rather than cartridges, which owners across the Dolphin line consistently find easier to rinse
Cons
- Its 4.4-star rating is POOLED across three machines — the Advantage, Advantage Ultra and Advantage Pro sell under one listing from $669 to $999, so the number does not describe the $669 unit specifically
- Maytronics publishes no micron figure for its filtration, here or anywhere in the Dolphin line
- Wi-Fi and app control are not part of this model — which, given how Dolphin's apps are rated by their current owners, is arguably not a loss
A season, and then the cord. "Worked great... for 1 season"; "I have had my Dolphin Advantage for 2.5 seasons now. I love it, but the cord i[s failing]"; "not as good as the original I purchased 5 years ago — this model has a shorter [cord]". The cord is the specific, repeated weak point, and one owner flags a practical trap around it: on a 33-foot in-ground pool the reach only works if the GFCI is within about six feet of the water. The cleaning itself splits owners — several praise the suction and wall scrubbing, while two say it misses: "it doesn't get all the dirt or scrub the walls well" and "not very smart" about coverage.
