The catch
Polaris 9650iQ Sport
A 70-foot cable does not amount to a universal pool-length approval
Side by side
Polaris 9650iQ Sport vs Dolphin CC Plus Wi-Fi Compared: Waterline-only cleaning and a retrieval routine come with Polaris
Quick verdict
Polaris 9650iQ Sport is the choice when waterline-only cleaning, assisted retrieval and the included transport caddy take care of real chores. Nautilus CC Plus Wi-Fi is the choice for its documented two-hour floor-and-wall cycle in pools up to 40 feet. Both give you connected powered cleaning. Neither the cable length nor an ultra-fine label proves that every pool or debris requirement is met.
Before you buy
Why, and what it costs you
Waterline dirt leaves the Dolphin owner with an extra job
This exact Nautilus CC Plus Wi-Fi covers floor and walls but makes no waterline-scrubbing claim, whereas Polaris documents a waterline-only mode. Polaris is the pick if that band is a recurring task you want the robot to handle. Dolphin can still work when floor-and-wall cleaning is enough and the pool is within 40 feet. Neither mode description proves that all residue or every surface material gets cleaned equally well.
Where this comes from
A documented difference in coverage is what this recommendation rests on. Neither app support nor a long cable makes up for a missing waterline mode.

What this page compares
Polaris 9650iQ Sport and Dolphin Nautilus CC Plus Wi-Fi are compared on waterline cleaning, retrieval, pool limits and filtration evidence.

I need a mode that cleans only the waterline
This Dolphin makes no waterline scrubbing claim, and Polaris documents that mode.

In practice
Differences you will notice
Waterline dirt leaves the Dolphin owner with an extra job
This exact Nautilus CC Plus Wi-Fi covers floor and walls but makes no waterline-scrubbing claim, whereas Polaris documents a waterline-only mode. Polaris is the pick if that band is a recurring task you want the robot to handle. Dolphin can still work when floor-and-wall cleaning is enough and the pool is within 40 feet. Neither mode description proves that all residue or every surface material gets cleaned equally well.
How we worked this out
A documented difference in coverage is what this recommendation rests on. Neither app support nor a long cable makes up for a missing waterline mode.
Help with retrieval can count for more than an extra app feature
Wi-Fi alone does not separate the pair, since both cleaners can be operated through an app. Polaris adds a transport caddy and Easy Lift, which brings it to the edge and expels water. It is the better fit when retrieving and moving a wet cleaner are the hard steps. You still have to lift, empty and maintain it. No comparable ready-to-lift wet-weight measurement was established for Dolphin, so this compares features and makes no lifting-force claim.
How we worked this out
What Easy Lift changes is the retrieval position and the handling of water. It does not take the cleaner out of the pool automatically, and neither source supports a claim of unattended self-emptying.
Ask about filter capacity and fineness separately
The current Dolphin configuration includes an ultra-fine basket, and Polaris specifies a 5-litre debris canister. The reviewed Dolphin source gives no comparable basket volume or verified micron rating, and Polaris's capacity says nothing about how fine its media is. Decide based on a confirmed debris requirement and the exact filter supplied. If you need a numerical micron threshold, verify that specification before picking either model from these labels.
How we worked this out
Storage volume is measured in litres, and particle-size filtration is measured in microns. You cannot convert an ultra-fine description into a numeric rating or use it to infer basket capacity.
Option A
Polaris, F9650IQ
9650iQ Sport
This 4WD cleaner for large pools trades the 9550 remote for iAquaLink control and scheduling.
- Best for
- Use a waterline-only mode that is documented
Facts we checked
- Coverage and program: A waterline-only mode is available.

- Control and retrieval: A transport caddy and app scheduling are included.
Option B
Dolphin, 99996409-PCI
Nautilus CC Plus with Wi-Fi
A connected cleaner for floor and walls, with MyDolphin Plus scheduling and a filter you reach from the top.
- Best for
- Stay within the 40-foot limit and rely on a two-hour floor-and-wall cycle
Facts we checked
- Coverage and program: Coverage includes floor and walls, without waterline scrubbing.
- Cable and sizing: The exact 99996409-PCI is rated for pools up to 40 feet.

- Control and retrieval: It uses a swivel power cable and MyDolphin Plus control.
Spec by spec
Where they really differ
| Spec | Polaris 9650iQ Sport | Dolphin Nautilus CC Plus with Wi-Fi | In practice |
|---|---|---|---|
| Coverage and program | A waterline-only mode is available. | Coverage includes floor and walls, without waterline scrubbing. | Polaris alone documents a waterline-only role. |
| Cable and sizing | The cleaner has a 70-foot swivel cable. | The exact 99996409-PCI is rated for pools up to 40 feet. | Maximum pool length is a separate measurement from cable length. |
| Debris handling | The debris canister holds 5 L. | The current configuration includes a top-load ultra-fine basket. | An ultra-fine label and canister volume describe different properties. |
| Control and retrieval | A transport caddy and app scheduling are included. | It uses a swivel power cable and MyDolphin Plus control. | Both are powered and connected, with Polaris adding a documented caddy. |
| Ownership task | Easy Lift brings the cleaner to the edge and expels water to assist owner retrieval. | Its standard cleaning cycle is two hours. | Assisted retrieval covers a part of the routine, and a fixed cleaning-cycle duration covers a separate part. |
Trade-offs
What each pick costs you
With Polaris 9650iQ Sport
- Even a 5-litre canister has to be emptied
With Dolphin Nautilus CC Plus with Wi-Fi
- The current exact model tops out at 40-foot pools
Change of plan
When the answer changes
Use a waterline-only mode that is documented
Go with Polaris 9650iQ Sport. You get Easy Lift retrieval assistance and the included caddy. A 70-foot cable does not amount to a universal pool-length approval.
Stay within the 40-foot limit and rely on a two-hour floor-and-wall cycle
Go with Dolphin Nautilus CC Plus with Wi-Fi. Go with the current top-load ultra-fine basket configuration. It makes no waterline-scrubbing claim.
Decision guide
How to decide
Polaris 9650iQ Sport fits waterline-only cleaning, assisted retrieval and the included transport caddy when those solve real chores. Nautilus CC Plus Wi-Fi fits its documented two-hour floor-and-wall cycle in pools up to 40 feet. Both offer connected powered cleaning, and neither the cable length nor an ultra-fine label proves every pool or debris requirement is met.
Waterline dirt leaves the Dolphin owner with an extra job
A waterline-only mode is documented for the Polaris, whereas this exact Nautilus CC Plus Wi-Fi covers floor and walls and makes no waterline-scrubbing claim. If that band is a recurring task you want the robot to handle, pick Polaris. The Dolphin can still be suitable when floor-and-wall cleaning is enough and the pool is within 40 feet. Neither mode description proves that all residue or every surface material gets cleaned equally well. The recommendation rests on a documented coverage difference. App support and a long cable do not make up for a missing waterline mode.
Help with retrieval can count for more than an extra app feature
App-connected operation comes with both cleaners, so Wi-Fi alone does not tell them apart. Polaris adds Easy Lift, which brings it to the edge and expels water, along with a transport caddy. Favor it if retrieving and moving a wet cleaner are the hard steps. You still have to lift, empty and maintain it. No comparable ready-to-lift wet-weight measurement was established for Dolphin, so this is a feature comparison and not a lifting-force claim. Easy Lift changes the retrieval position and water handling. It is not automatic removal from the pool, and neither source supports a claim of unattended self-emptying.
