Dolphin versus Aiper is a useful starting point, but it is too broad to decide a purchase. Both brands have multiple families and generations. Comparing an entry-level floor cleaner with a premium waterline model tells you more about their categories than their logos.
Compare matched models with the same cleaning zones, supported pool size and filter needs. Nautilus CC Plus Wi-Fi versus an exact Scuba S1 generation is one useful ownership comparison. Include Dolphin's cordless lines and Aiper's newer ranges before assuming one brand is always corded and the other always the only cordless option.

Use these candidates to narrow the job and ownership routine. The notes below explain the tradeoffs; listing presence is not a guarantee of current Amazon availability.
| Candidate | Reason to investigate | What to confirm |
|---|---|---|
| Nautilus CC Plus Wi-Fi vs Scuba S1 | Midrange ownership comparison | Corded routine versus generation-specific cordless features |
| Dolphin E10 vs Scuba SE | Entry floor-cleaning comparison | Match floor shape, budget and filtration |
| Dolphin waterline model vs suitable Aiper | Coverage-matched comparison | Confirm actual zones and size before price |
| Dolphin cordless family vs Aiper cordless | Cable-free ownership comparison | Compare precise models, not brand stereotypes |
Build a fair comparison first
Put coverage, pool limits, surface compatibility, filter configuration and power source in the first five rows of your comparison. If a model fails one of your required rows, remove it before comparing apps or discounts. This keeps a better-equipped model from winning simply because it was put against an unsuitable rival.
Then compare the ownership routine: retrieval, charging or cable storage, basket cleaning, replacement filters and access to service. These are repeated tasks. A feature you rarely use should not outweigh a maintenance step you find difficult every week.
The corded-versus-cordless stereotype is incomplete
Dolphin's established corded models make a floating-cable comparison useful, but the catalog also includes cordless Nautilus EON products and other cordless Dolphin lines. Aiper's current lineup is broader than the old SE-and-S1 pairing. Treat a brand comparison as a map of choices rather than a fixed technology verdict.
If you want a cable-free pool, compare actual cordless candidates from both brands. If you prefer another cycle without charging, focus on corded models that meet your requirements. Neither route proves a brand-level cleaning-performance or reliability advantage.
Generations and filter kits can distort the result
Scuba S1 names cover different generations with changing controls and filtration. Dolphin model suffixes also change coverage and equipment. A 'Plus' or 'Pro' label does not describe the same upgrade across different families or brands.
Write the manufacturer's product number beside each model name. Record what comes in the box and what costs extra. Compare a complete usable setup rather than a standalone robot on one side and a bundle on the other. If the retailer and manufacturer disagree, resolve it before treating the two offers as equivalent.
Service deserves a real place in the decision
Check warranty terms for the exact seller and model, where a repair would be handled, what you would pay for shipping, and whether common wear parts are available. Do not claim one brand always lasts longer without credible failure-rate evidence.
A useful service question is concrete: 'If this brush, battery or power supply needs replacement, what is the part number and service route?' Ask it before purchase. A cheaper robot with unclear support can be a poor long-term choice, while a premium robot with features you never use can also be poor value.
For a small flat pool, compare entry floor cleaners. For a pool needing waterline work, compare waterline-rated models. Once the categories match, your preference for cable handling or charging can become decisive. Changing the logo without matching the job does not create a fair comparison.

I am choosing my first cleaner
Start with the buying guide to match cleaning zones, pool geometry and your maintenance routine. Use this article’s shortlist only after those requirements are clear.
I already own a cleaner but one chore remains
Identify the missed zone or debris type. Check compatible filters and the manual before replacing the entire cleaner. For a replacement decision, compare repair and replacement costs.
I have narrowed it to two models
Compare exact product numbers, included equipment and seller support. Browse current cleaner options and confirm the final offer before purchase.

Common questions
Is Dolphin always corded?
No. Compare its actual current model families, including cordless products, rather than assuming every Dolphin uses a cable.
Is Aiper always cheaper?
No universal rule applies. Compare current prices for equivalent coverage and included equipment.
Which brand cleans better?
That requires evidence for matched models in comparable pools. Brand names alone cannot establish a winner.
