Ringside notes

This rivalry is really a philosophy fight. Aiper is the cordless value insurgent — the Scuba S1's 798-owner base and the S3's 4.7★ are the crowd behind it. Dolphin is Maytronics, the corded old guard: its strongest fighters don't carry a battery at all. The brands share exactly one division, and even that fight is unsettled — the Scuba V3 Ultra and the corded Dolphin M600 both lost the Super Heavyweight belt to the Beatbot AquaSense 2 Ultra, so no ruling exists between them. Dolphin's cordless attempt, the Liberty 300, fights alone at Light Heavyweight (it lost that division too, and it cannot be compared to an Aiper on owner rating at all — it is not sold on Amazon, so no independent base exists; its only number is Maytronics' own 3.9★ from 26 reviews, and a maker's page runs about a star high). The fight that actually matters to a buyer is off the ladder: the Scuba S1 vs the corded Nautilus CC Plus, cordless convenience against a 3,260-owner corded workhorse that never needs charging. That matchup page carries the full tale of the tape.

FAQ

Which is better, Aiper or Dolphin?

No division fight between them has been ruled. The honest split: Aiper wins the cordless value question on the S1's deep base (4.3★/837 at ~$500), though the S3 has since cooled to 4.3★/116; Dolphin's best case is corded — the Nautilus CC Plus's 3,260-owner base and the M600's no-battery-to-die flagship argument. Decide cord-vs-cordless first; the brand answer follows.

Is the Dolphin Liberty 300 a good Aiper alternative?

It's Dolphin's cordless entry, and the case against it is capability and price rather than stars: no surface skimming, no app, 2.5-hour cycles, and $1,249 — $50 more than the Beatbot Sora 70 that beat it in our Light Heavyweight division while doing more. You can't line it up against an Aiper on owner rating, because it isn't sold on Amazon and has no independent base; the only rating is Maytronics' own 3.9★/26, which is a brand page and reads about a star high. If you want Maytronics reliability, their corded machines are the better expression of it.

Aiper Scuba S1 or Dolphin Nautilus CC Plus?

The real question in this rivalry — cordless vs corded. The S1 brings the proven cordless base (4.3★/837, ~$500, light-debris pools); the CC Plus brings corded stamina (no battery, big pools, 3,260 owners at 3.6★). We haven't ruled it; the matchup page lays out what would decide it.
