The Aiper Scuba S1 and Dolphin Nautilus CC Plus Wi-Fi are often compared as if the only decision is which cleans better. Without a controlled test in your pool, that is not a claim we can make. The useful comparison is how their coverage, filtration and daily routines fit the way you maintain your pool.
Choose the CC Plus Wi-Fi when you prefer a corded floor-and-wall routine and have a suitable power location. Choose the exact S1 generation when avoiding a floating cable matters enough to accept charging. If dedicated waterline cleaning is essential, verify the S1 version and consider a Dolphin model explicitly rated for that job.

Compare the shortlist
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 |
|---|---|---|
| Dolphin Nautilus CC Plus Wi-Fi | Corded; floor and walls | Do not infer dedicated waterline coverage from wall climbing |
| Current Aiper Scuba S1 | Cordless; version-dependent features | 2026 and older listings should not share one specification row |
| Dolphin Nautilus CC Pro | Alternative when waterline is a priority | Compare exact-model price and filter kit |
A cable versus a charging routine
The Dolphin uses a floating cable and an external power supply. That means you can start another permitted cycle without waiting to recharge a battery. It also means planning cable placement, keeping the supply where the manual requires, and storing the cable without damaging it. Corded does not mean maintenance-free.
The S1 removes the floating cable, but adds a dry charging step and battery-dependent operation. Think through where you will retrieve it, allow it to drain and charge it. If you clean before visitors arrive, the time between cycles can be as important as the maximum runtime printed in an advertisement.
Model generations change the answer
The catalog includes an older Scuba S1 and a 2026 S1 with different described capabilities. The current Aiper page also mixes headline runtime claims with different cycle specifications. That is a reason to confirm the exact version and cleaning mode, not to combine the biggest number from each listing into an imaginary specification.
The CC Plus Wi-Fi has its own naming problem. The site's listing describes pools up to 50 feet, while the current manufacturer comparison displays 40 feet. If your pool sits between those values, ask Maytronics which limit applies to the exact product number you intend to buy. Do not use this article as an assurance that either listing overrides the manual.
Compare coverage before connectivity
An app can make starting or scheduling more convenient, but it cannot add brushes or a cleaning zone the machine lacks. The CC Plus is a floor-and-wall cleaner; dedicated waterline cleaning is not its defining specification. The current S1 page describes additional features, but they must be matched to the sold generation.
If the tile band is your main chore, make that a pass-or-fail requirement. Compare a waterline-rated Dolphin such as the CC Pro with the relevant S1 version. If the floor and walls are the main problem, you can spend less attention on app features and more on filter configuration and comfortable retrieval.
Which ownership routine wins in your pool?
A lightly used pool cleaned on a flexible schedule can accommodate charging easily. A pool that needs another cycle soon after a heavy debris load may make the corded routine attractive. Neither observation proves one model has better pickup or long-term reliability; those require actual evidence.
For fine dust, verify the included filter stages and compatible accessories. For leaves, compare basket access and loading. For lifting, check drained weight and handle position rather than assuming cordless is lighter. Ask the seller about service, returns and model identification before making a decision on a temporary discount.
If you already have a convenient outlet and dislike charging devices, the Dolphin's cord may be an acceptable trade. If a cable regularly complicates your pool setup and you can charge between runs, the S1's cordless routine is more compelling. Let that routine narrow the choice before comparing app screens.

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
Does the CC Plus Wi-Fi scrub the waterline?
Its manufacturer coverage is floor and walls. Look at a model explicitly rated for waterline cleaning if that is essential.
Does every Scuba S1 have the same app and filters?
No. Confirm the generation and included equipment rather than carrying newer claims into an older listing.
Which is more reliable?
This specification comparison does not establish a failure-rate winner. Compare warranty, repair access and credible long-term evidence for the exact models.
