Differences Between Dolphin Cayman vs Dolphin Nautilus CC Plus
Below is a summary of the specifications:
Design Comparison
The Dolphin Cayman is built for in-ground pools up to 33 feet, making it ideal for smaller backyard pools. It features a 50-foot cable without a swivel mechanism, which can lead to occasional tangling during operation. Weighing only 14 pounds, the Cayman is light and easy to handle, especially when lifting it out of the water.
In comparison, the Dolphin Nautilus CC Plus Wi-Fi is designed for larger pools up to 50 feet in length. It includes a 60-foot cable with anti-tangle swivel, significantly improving mobility and coverage without cable mess. At 19 pounds, it is heavier than the Cayman, but its premium build and enhanced pool compatibility make it better suited for expansive pools.
Winner: Dolphin Nautilus CC Plus Wi-Fi
Its longer cable, swivel design, and support for larger pool sizes give it a clear edge in flexibility and reliability.
Cleaning Performance Comparison
The Dolphin Cayman features a single HyperBrush™ active roller, which spins twice as fast as standard brushes, delivering strong agitation to lift debris and algae from pool surfaces. It operates at a suction rate of 4000 gallons per hour and uses a fine top-load filter basket, efficient for everyday dirt, leaves, and sand. However, it does not support waterline scrubbing and only uses a single-layer filter.
Meanwhile, the Dolphin Nautilus CC Plus Wi-Fi is equipped with dual scrubbing brushes, one in front and one in back, offering broader and more consistent scrubbing coverage. Its 4500 GPH suction rate allows it to clean faster and more thoroughly. It uses a dual-layer filtration system combining fine and ultra-fine filters, ideal for capturing both larger debris and fine particles like pollen or algae. Although it also doesn’t scrub the waterline, its broader cleaning path and filtration capability offer superior performance overall.
Winner: Dolphin Nautilus CC Plus Wi-Fi
With higher suction, dual brushes, and a dual-stage filter, it outperforms the Cayman in thoroughness and debris removal.
Feature Comparison
The Dolphin Cayman offers a basic but functional approach to pool cleaning. It includes a built-in weekly scheduler on its power supply, allowing users to set it to clean daily, every other day, or every third day. However, it does not have any smart features, mobile app integration, or Wi-Fi connectivity. It is a plug-and-play model that relies on manual setup and operation.
In contrast, the Dolphin Nautilus CC Plus Wi-Fi delivers modern convenience through the MyDolphin Plus app, which allows users to schedule, start, or stop cleanings remotely via smartphone. The app also provides updates and customization options that enhance the user experience. This level of control gives the Nautilus a more future-ready profile, especially for users who want flexibility and automation in how and when their pool is cleaned.
