Dolphin Cayman Vs Nautilus CC. When it comes to keeping our pools clean and sparkling, robotic pool cleaners have become a popular choice for their efficiency and convenience.

In this article, we will compare two well-known robotic pool cleaners: the Dolphin Cayman and the Nautilus CC.

By examining their features, pros, and cons, we aim to help you make an informed decision based on your specific needs and preferences.

Operation: Tie

Both the Dolphin Cayman and Nautilus CC offer easy and hassle-free operations. They feature a plug-and-play design, allowing you to simply drop the robot into the pool and turn on the power supply. 

This straightforward setup ensures that your pool cleaner can get to work in a matter of seconds.

Pool Compatibility: Tie

Both cleaners are designed to be compatible with various pool types, including Gunite, vinyl, tile, and plaster. 

Whether your pool has a specific surface material, these cleaners can effectively navigate and clean the pool surfaces.

Cleaning Coverage: Nautilus CC

  • The Dolphin Cayman focuses on cleaning the floor and walls of the pool. It employs advanced navigation technology to ensure that every inch of the pool is covered, leaving no area untouched. 
  • On the other hand, the Nautilus CC offers enhanced cleaning coverage by not only cleaning the floor and walls but also addressing the waterline. This extended cleaning capability provides a more thorough and comprehensive cleaning experience.

Filtration System: Tie

An efficient filtration system is essential for maintaining a clean and healthy pool. The Dolphin Cayman is equipped with a filtration system that targets dirt, debris, leaves, and pebbles from every corner of the pool. The filters of this cleaner are easily removable from the cartridge, allowing for convenient cleaning by rinsing them with a garden hose.

The Nautilus CC, on the other hand, features two extra-large cartridges that offer superior filtering capabilities, ensuring that your pool water remains crystal clear.

Scrubbing Capabilities: Nautilus CC

Both the Dolphin Cayman and Nautilus CC excel in their scrubbing abilities.

The Nautilus CC stands out with its HyperBrush, which spins twice as fast as standard pool brushes. This powerful scrubbing action helps to effectively remove tough stains from your pool’s surfaces. 

Additionally, the Nautilus CC comes equipped with three brushes instead of two, allowing for even better scrubbing performance. The inclusion of a center scrubbing brush enables it to target walls and the waterline with precision.

Energy Efficiency: Tie

Energy efficiency is an important consideration for many pool owners. Both the Dolphin Cayman and Nautilus CC are designed to be energy-efficient, resulting in lower electricity consumption.

By choosing an energy-efficient pool cleaner, you not only save money on your electricity bills but also contribute to a greener and more sustainable environment.

User Comfort and Convenience: Tie

User comfort and convenience are key factors when selecting a robotic pool cleaner. Both the Dolphin Cayman and Nautilus CC prioritize user comfort by offering features that enhance the overall experience.

They feature top-access filter compartments, eliminating the need to handle messy and cumbersome debris bags. This design makes it easier to remove and clean the filters, adding to the user-friendly nature of these cleaners.

Navigation: Tie

Both the Dolphin Cayman and Nautilus CC boast advanced navigation systems. These systems ensure efficient coverage of the pool, allowing the cleaners to navigate around obstacles and reach all areas of the pool. 

With their smart navigation capabilities, you can trust that these cleaners will effectively clean every nook and cranny of your pool.

Connectivity Features: Nautilus CC 

The Nautilus CC supports connectivity features such as Wi-Fi, Bluetooth, and smartphone control, providing added convenience and control over the cleaning process.

The Dolphin Cayman has none of these features. 

Additional Features: Nautilus CC

The Dolphin Cayman and Nautilus CC offer some additional features that may influence your decision.

The Dolphin Cayman includes a weekly scheduling feature, allowing you to set cleaning sessions according to your preferred schedule. This eliminates the need to manually start the cleaner each time. 

On the other hand, the Nautilus CC comes with a full bag indicator, which provides a convenient visual alert when the filter bag needs to be emptied. This feature ensures that the cleaner operates at its optimal performance and minimizes maintenance interruptions.

Stair and Wall Cleaning: Nautilus CC

Cleaning stairs and walls can be a challenge for robotic pool cleaners.

The Dolphin Cayman effectively cleans pool floors and walls but may struggle with stairs.

The Nautilus CC, equipped with three brushes, handles walls and the waterline with greater efficiency. It has an edge with stairs, thanks to its HyperBrush and unique brush system, but may still encounter some difficulty.

In summary, the Nautilus CC provides slightly better performance for stair and wall cleaning, but manual intervention may be needed for complete stair cleaning with both models.

Cleaning Modes and Scheduling Options: Nautilus CC

The number of cleaning modes and scheduling options a robotic pool cleaner offers can greatly influence its utility and convenience.

The Dolphin Cayman has a user-friendly operation with weekly scheduling, allowing you to customize cleaning sessions to fit your schedule. However, it has limited cleaning mode options, which may reduce its versatility.

The Nautilus CC, on the other hand, stands out with three cleaning cycles – quick, standard, and enhanced – offering more flexibility to suit different cleaning needs. Like the Cayman, it also supports weekly scheduling, providing you with added convenience.

In terms of cleaning modes and scheduling options, the Nautilus CC holds an advantage with its wider range of cleaning cycles.


Both the Dolphin Cayman and Nautilus CC are reputable robotic pool cleaners that offer effective cleaning performance and convenience.

  • The Dolphin Cayman excels in its exceptional scrubbing and filtration capabilities, easy maintenance, and energy efficiency. However, it lacks connectivity features and a remote control.
  • On the other hand, the Nautilus CC provides great scrubbing and filtering abilities, connectivity options, multiple cleaning cycles, and a tangle-free cable. However, it may encounter challenges with cleaning stairs and lacks a remote control and a caddy.  

When choosing between the Dolphin Cayman and Nautilus CC, consider factors such as pool size, desired cleaning coverage, connectivity preferences, and personal convenience.

My Choice

Personally, I’d choose the Nautilus CC of the two.  It’s got superior scrubbing capabilities, Wi-Fi and smartphone connectivity and a tangle-free cable.  

Yeahhhh, it’s not as good with stairs, but it more than makes up for that with it’s other features in my opinion, and I don’t mind taking a scrub brush to the stairs every once in a while if my pool guy doesn’t get em.  Grab yours from Amazon now.
