Aiper Scuba S1 vs Dolphin Nautilus CC Plus
cordless convenience vs the corded workhorse
Dolphin Nautilus CC Plus
Tale of the tape — this fight hasn't been booked yet
No showdown has ruled between these two. What follows is the verified data, not a verdict.
Ringside notes
The most-asked cross-brand question in pool robots isn't really about these two machines — it's about the cord. No showdown has ruled between them (they shared only our pound-for-pound roundup, where the Beatbot AquaSense 2 took best overall), so this is a tale of the tape between two philosophies. The Scuba S1 is cordless convenience with the deepest proof in the class: 4.2★ across 856 owners at ~$550, happiest in light-debris pools up to ~1,600 sq ft, done in 150 minutes and back on its charger. The Nautilus CC Plus is the corded workhorse: a 3,086-owner base (at an honest, middling 3.6★), no battery to charge, age, or replace, and the stamina to run as long as a big pool needs — the reason it took "best for big pools" in that roundup. The trade is exact: the S1 asks you to charge it; the CC Plus asks you to manage a cable every session, forever. Small-to-mid pool, light debris: S1. Big pool, heavy debris, decade of ownership: the cord is the boring right answer.

What would decide it
- Owner proof: Aiper Scuba S1 reads 4.5★ across 804 owners; Dolphin Nautilus CC Plus reads 3.6★ across 3,160. Depth of sample matters as much as the star.
- The hidden consumable: Aiper Scuba S1 battery — Not stated; Dolphin Nautilus CC Plus — not stated. A robot whose battery can't be replaced IS the consumable.
- Aiper Scuba S1 — your pick if: you want the most owner-proven pick in cordless value — 4.5★ across 804 owners at about $500 — and you'd rather sidestep WYBOT's brand risk; best for light-debris pools, not heavy silt or the biggest pools.
- Dolphin Nautilus CC Plus — your pick if: you have a big pool (up to ~50 ft) and want a corded workhorse that runs as long as you need with no battery to replace — as long as you'll manage a cord and live with flaky Wi-Fi.

“I picked up a S1 a few weeks ago and have been very impressed. It cleans just as good as my old Maytronics, for half the price and no cord.”— JJ_Tex, verified owner (Trouble Free Pool)
- Excellent price-to-performance
- Cleans the waterline too
- Long runtime for the price (~270 min floor-only; ~150 min combined)

“It's been reliable in over a year of ownership, with few issues.”— The Pool Nerd

- Runs as long as you need — no battery
- Proven, owner-loved reliability
- Great for large pools
- You manage a floating cord
- Doesn't always hit the waterline as aggressively as top cordless models
- Owners report flaky Wi-Fi/app connectivity — the main drag on its 3.6★ rating
FAQ
Which is better, the Aiper Scuba S1 or the Dolphin Nautilus CC Plus?
No fight between them has been ruled — in our pound-for-pound roundup both lost best-overall to the Beatbot AquaSense 2, with the S1 taking best value and the CC Plus best for big pools. The real decision is cordless convenience (S1) versus corded stamina and no battery to age (CC Plus).
Why does the CC Plus rate only 3.6★ with so many owners?
A 3,086-owner base at 3.6★ is the profile of a long-selling workhorse: enormous proof volume, honest wear-and-tear complaints included. We'd weight it differently than a young 4.5★ on 50 reviews — it's the most battle-tested data point on this card, not the prettiest.
What does the cord actually cost me day to day?
Handling: you deploy and retrieve a tethered robot each session and occasionally untwist the cable. What it buys: unlimited runtime for big pools, no charging window, and no battery that fades into a replacement decision — the CC Plus will run the same in year six as year one.
