The catch
Polaris 9550 Sport
App control is missing
Side by side
Polaris 9550 Sport vs Dolphin Nautilus CC Supreme Compared: Dolphin offers phone control and fine media, Polaris covers a 60-foot pool
Quick verdict
Polaris 9550 Sport is the choice for a pool over 50 and up to 60 feet, physical remote steering and its included transport caddy. Nautilus CC Supreme is the choice for MyDolphin Plus control and both fine and ultra-fine filter kits. Since both clean floors, walls and the waterline, your control and handling needs decide it.
Before you buy
Why, and what it costs you
Polaris is the pick for a 55-foot pool
The pool is past Supreme's 50-foot rating and inside Polaris's 60.
Where this comes from
Polaris's separate 70-foot cable does not change the pool-length rating. 55 > 50 and 55 ≤ 60.

In practice
Differences you will notice
Polaris is the pick for a 55-foot pool
The pool is past Supreme's 50-foot rating and inside Polaris's 60.
How we worked this out
Polaris's separate 70-foot cable does not change the pool-length rating. 55 > 50 and 55 ≤ 60.
A physical remote is not replaced by an app
Each supported interface suits a different preference.
How we worked this out
A motion-sensing remote is included with Polaris, which lists no app. For Supreme, the listing is MyDolphin Plus and no physical remote.
The package changes with the handling equipment
Polaris has a documented caddy as well as assisted retrieval.
How we worked this out
In the 9550 table, Transport Caddy reads Included and Easy Lift reads Yes. The Supreme base record that was reviewed does not establish equivalent equipment.

Spec by spec
Where they really differ
| Spec | Polaris 9550 Sport | Dolphin Nautilus CC Supreme | In practice |
|---|---|---|---|
| Maximum pool length | 60 ft | 50 ft | Total cable length is not the same as pool length. |
| Control method | Physical motion-sensing remote, no app | MyDolphin Plus, no physical remote | Let the interface you need decide. |
| Retrieval assistance | Easy Lift surfaces the cleaner and evacuates water | No equivalent feature established in reviewed specification | Broad claims about portability do not prove the same level of assistance. |
| Transport caddy | Included | Not confirmed in base record, separate bundles exist | Look in the exact package. |
| Filtration | 5 L canister with dirty-canister indicator | Fine plus ultra-fine kit, no full-filter indicator | Volume, media and reminder sensors each do something different. |
| Coverage | Floor, wall and waterline modes | Floor, walls and waterline | Both support the same surfaces. |
Trade-offs
What each pick costs you
With Polaris 9550 Sport
- A caddy takes storage space and still leaves lifting to do
With Dolphin Nautilus CC Supreme
- Nothing confirms that the base offer includes a caddy
Change of plan
When the answer changes
Pool length runs from above 50 up to 60 feet
Go with Polaris 9550 Sport. This is past what Supreme's published length rating allows.
Control has to be from a phone
Go with Dolphin Nautilus CC Supreme. 9550 lacks an app.
You need steering with a physical remote
Go with Polaris 9550 Sport. The 9550 has it documented.
Decision guide
How to decide
Polaris 9550 Sport fits a pool over 50 and up to 60 feet, physical remote steering and its included transport caddy. Nautilus CC Supreme fits MyDolphin Plus control and both fine and ultra-fine filter kits. Control and handling needs make the difference, because both clean floors, walls and the waterline.
Find the longest dimension of your pool
Supreme is out for a 55-foot pool, although both are corded. What counts is the 60-foot pool rating of the 9550. Cable length tells you about installation and is not a substitute rating.
Decide on the control interface
For targeted poolside steering, a handheld remote may fit. For scheduling from a phone, an app may fit. If you require one or the other, the choice is clear, and everyone else can decide based on handling and filter equipment.
Go through the package list
A caddy and Easy Lift are documented for the Polaris, and additional ultra-fine media for the Supreme. Retailer bundles can vary, so confirm the selected package before you put any value on a caddy, cover or extra filters.
What this page can’t tell you
