Now, let's delve into how we test these robotic pool cleaners. Our process evaluates them based on pool coverage, filtration options, and their feature set and warranty. This comprehensive approach ensures we can provide you with the most accurate and useful information for your pool maintenance needs.
To ensure our readers get the most accurate and helpful information, we thoroughly test each robotic pool cleaner over a period of three months. During this time, we closely examine various aspects of the robot's performance. Our focus includes pool coverage, filtration ability, and the feature set and warranty. This comprehensive approach ensures that we can truly assess how each model performs in real-world conditions, providing you with the best advice for your pool maintenance needs.
One of the first areas we test is pool coverage. For models like the Dolphin Cayman, we observe how well it navigates and cleans different areas of the pool. This includes the floor and walls, ensuring it doesn't miss any spots. We were particularly impressed with the Cayman's ability to clean efficiently due to its Smart Nav 2.0 software and HyperGrip tracks. The Dolphin Cayman excelled in these tests, demonstrating strong cleaning power and a clear path over the pool floor.
In contrast, the Dolphin Sigma took pool coverage to the next level. Built on a commercial-grade platform, it features three powerful motors and advanced navigation capabilities, including a gyroscope. This ensures the Sigma can handle tight turns and maintain precise paths, resulting in comprehensive cleaning. The gyroscope also aids its ability to climb and clean the waterline, which is often the dirtiest part of any pool.
Testing the filtration ability of these robots is another critical aspect of our review process. For the Cayman, we noted its standard fine filter, which handled everyday cleaning needs effectively. However, for more challenging tasks like dealing with cloudy water or fine particles, the included NanoFilters made a significant difference. The Cayman's filters are easy to remove and clean, making maintenance a breeze.
Moving on to the Dolphin Sigma, we were pleased to find it includes both standard and ultrafine filters. These filtration options are crucial for maintaining crystal-clear water by capturing even the smallest particles. The Sigma's oversize filter capacity allowed it to handle large debris and fine particles equally well, enhancing overall pool cleanliness.
Of course, assessing the feature set and warranty is vital for understanding the long-term value of these pool robots. The Dolphin Cayman stands out with its weekly timer, allowing automated cleanings without user intervention. This feature, combined with the Cayman's robust build and reliable performance, makes it a great option for those seeking convenience and value.
The Dolphin Sigma, on the other hand, enhances user experience through its advanced app interface, enabling remote control and scheduling. The three-year warranty further underscores the Sigma's durability and reliability, offering peace of mind for pool owners. This combination of features and warranty makes the Sigma an unbeatable choice for those looking for top-tier performance and ease of use.
In conclusion, after three months of rigorous testing, both the Dolphin Cayman and Dolphin Sigma proved their worth in distinct ways. The Cayman shines with its automation and ease of use, making it ideal for those who prioritize convenience. Meanwhile, the Sigma's advanced features and robust design make it perfect for those seeking the ultimate in pool cleaning technology.

Comparing the coverage capabilities of the Dolphin Cayman and Dolphin Sigma reveals noticeable differences in what parts of the pool they clean and how effectively they do so. The Dolphin Cayman excels in floor and wall cleaning. It's equipped with Smart Nav 2.0 software and HyperGrip tracks which allow it to navigate and clean most parts of the pool with precision.
While the Dolphin Cayman provides an impressive clean, it does not extend its coverage to the waterline. This is one major area where the Cayman falls short, especially for pool owners who notice significant debris accumulation at the waterline. However, it navigates the pool floor and walls effectively, taking advantage of its HyperBrush to scrub and collect debris efficiently.
On the other hand, the Dolphin Sigma offers a more comprehensive pool coverage. Built on a commercial-grade platform, it is equipped with three powerful motors and a gyroscope which enhances its navigation capabilities. The Sigma is capable of cleaning the pool floor, walls, and most importantly, the waterline—where debris and scum often accumulate.
The Dolphin Sigma is designed to cover every inch of the pool, ensuring even the toughest spots are cleaned. The gyroscope aids in maintaining its position and stability, allowing it to effectively clean the waterline—a component often missed by other pool robots. This advanced feature sets the Sigma apart, making it more suited for comprehensive pool cleaning.
In terms of pool coverage scores, the Cayman scores well with a solid 10, but it’s important to note it does not clean the waterline. Meanwhile, the Sigma also earns a perfect score of 10 in pool coverage, excelling in its ability to clean the entire pool, including the waterline. This makes the Sigma a superior choice for thorough, all-encompassing pool cleaning.
For pool owners who prioritize waterline cleaning and advanced navigation, the Dolphin Sigma is the clear winner. Its ability to maintain a precise path and cover all hard-to-reach areas sets it apart. However, if you are looking for a reliable and less expensive option that provides excellent floor and wall cleaning, the Dolphin Cayman remains a strong contender.
In conclusion, both the Dolphin Cayman and Dolphin Sigma offer outstanding pool coverage, but their specific strengths cater to different needs. The Dolphin Cayman provides superior floor and wall cleaning with automation features, while the Dolphin Sigma offers the most advanced and comprehensive pool coverage, including the crucial waterline.
