Head-to-head
Polaris 9550 Sport vs Dolphin Nautilus CC Supreme: Polaris reaches a 60-foot pool, Dolphin adds phone control and fine media
The short answer
Choose Polaris 9550 Sport for a pool above 50 and up to 60 feet, physical remote steering and its included transport caddy. Choose Nautilus CC Supreme for MyDolphin Plus control and both fine and ultra-fine filter kits. Both clean floors, walls and the waterline, so control and handling needs make the difference.
Before you choose
The reasoning and the trade-offs
A 55-foot pool selects Polaris
It exceeds Supreme's 50-foot rating and fits Polaris's 60.
What this is based on
55 > 50 and 55 ≤ 60. Polaris's separate 70-foot cable does not change the pool-length rating.

What matters in practice
The differences that matter
A 55-foot pool selects Polaris
It exceeds Supreme's 50-foot rating and fits Polaris's 60.
How we reached this conclusion
55 > 50 and 55 ≤ 60. Polaris's separate 70-foot cable does not change the pool-length rating.
An app does not replace a physical remote
The supported interfaces address different preferences.
How we reached this conclusion
Polaris lists no app and includes a motion-sensing remote. Supreme lists MyDolphin Plus and no physical remote.
Handling equipment changes the package
Polaris documents both a caddy and assisted retrieval.
How we reached this conclusion
The 9550 table lists Included for Transport Caddy and Yes for Easy Lift. The reviewed Supreme base record does not establish equivalent equipment.

Meaningful differences
What changes the fit
| What changes | Polaris 9550 Sport | Dolphin Nautilus CC Supreme | Why it matters |
|---|---|---|---|
| Maximum pool length | 60 ft | 50 ft | Pool length differs from total cable length. |
| Control method | Physical motion-sensing remote, no app | MyDolphin Plus, no physical remote | Choose the interface you require. |
| Retrieval assistance | Easy Lift surfaces the cleaner and evacuates water | No equivalent feature established in reviewed specification | General portability claims do not prove the same assistance. |
| Transport caddy | Included | Not confirmed in base record, separate bundles exist | Check 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 are different features. |
| Coverage | Floor, wall and waterline modes | Floor, walls and waterline | Supported surfaces are shared. |
What you give up
Every choice has a cost
If you choose Polaris 9550 Sport
- The caddy needs storage and does not eliminate lifting
If you choose Dolphin Nautilus CC Supreme
- Caddy inclusion is not confirmed for the base offer
Recommendation switch
The decision flips if...
The pool is above 50 and up to 60 feet
Choose Polaris 9550 Sport. Supreme is outside its published length rating.
Phone-based control is required
Choose Dolphin Nautilus CC Supreme. 9550 has no app.
Physical remote steering is essential
Choose Polaris 9550 Sport. It is documented for the 9550.
What matters in practice
How to make the call
Measure the longest pool dimension
A 55-foot pool rules out Supreme even though both are corded. The 9550's 60-foot pool rating is the relevant figure. Cable length is installation information rather than a substitute rating.
Choose the control interface
A handheld remote can suit targeted poolside steering. An app can suit scheduling from a phone. Buyers who require one have a clear choice, while other buyers can decide around handling and filter equipment.
Read the package list
Polaris documents a caddy and Easy Lift. Supreme documents additional ultra-fine media. Retailer bundles can vary, so confirm the selected package before assigning value to a caddy, cover or extra filters.
What this comparison cannot tell you
- No remote-precision, pickup, durability or lifting-force tests were performed. Unconfirmed package contents remain conditional.
