Dolphin Nautilus vs Sigma
Build Quality and Look
One can see the difference in their appearance just by browsing over the two cleaners, the Dolphin Sigma comes with comes in shining clear white with a bit of royal blue whereas the Nautilus comes in the colour combination of refreshing blue and elegant black. The dolphin Sigma comes with the dimensions of 23 x 19.5 x 13.5 inches and a weight of 35 pounds. Whereas the dolphin nautilus has dimensions of 16.38 x 16.77 x 8.97 inches and a feather lightweight of just 13.8 pounds. On comparing the physical features, we can discover that Dolphin Nautilus is extremely lightweight.
It would be easier to handle the nautilus as compared to sigma due to the lightweight of the cleaner. The Sigma comes with 60 feet long, 360-degree rotating Swivel cable. In place of wheels, the cleaner uses HyperGrip continuous rubber tracks. These tracks can counter the friction arising due to water and securely plant these robots on the floors and walls of pools. The tracks also allow the smooth movement of the cleaner while cleaning. The Nautilus also comes with a long cable length of 50 feet however it does not come with an anti-tangle feature and instead of wheels it also comes with tracks.
Cleaning Technique
The most vital feature to keep a close eye on for a cleaner is the cleaning capability and the cleaning technique. Sigma works on a dual scrubbing brush system. There are two brushes at the front and two at the back to reach corners and angles. Both of them cover the pool surface of gunite/plaster, vinyl, and fiberglass. In addition to that, there is a brush that is included in the center of the Sigma, it ensures further cleaning. The scrubbing brushes are able to loosen bio-film and algae from the surface of the pool before sucking the dirt into the filter.
When it comes to the Nautilus it has a powerful active brush, this single brush is able to carefully scrub dirt and algae from the surfaces of the pool all the way to the pool’s waterline. This brush is able to move at a fast pace, the speed is double the speed of the robot’s speed ensuring complete dirt removal. It not only scrubs your pool’s surface but is also able to give the robot enough power to climb the walls of the pool. The cleaner comes with tracks instead of wheels which ensures good grip and friction to be able to pick up huge leaves. The single brush of the nautilus is quite effective.
Navigation System
Both the cleaners work smartly and instead of roaming around aimlessly, they use inbuilt smart navigation systems. The key area of difference between the two cleaners lies in the different navigation systems. Sigma is equipped with the latest technology of SmartNav. SmartNav system just requires a few seconds of submersion in the water to be able to scan the area and then plans the area that needs to be cleaned by avoiding obstacles in its way. This navigation system avoids the cleaner to go to the same place which has been already cleaned. Similar to the incredible SmartNav technology is the navigation system of CleverClean Technology.
The CleverClean technology is present in the nautilus, which is designed to swiftly scan the swimming pool and gather information regarding the measurements and shape of the pool. With this, the cleaner is sent to an efficient route by covering the walls and the side area of the pool. It also helps in identifying and avoiding obstacles. The cleaner is also able to create a new route with every new cleaning cycle. The special algorithm used by the software ensures that the cable cord remains tangle-free. Both the cleaners are head-to-head with their features however, one additional feature of Sigma that makes it difficult for nautilus to come close to it is the onboard gyroscope. The Gyroscope mobility system is able to target alignment as well as the slant. The gyroscope can monitor angular velocity around the 3-axis of rotation. The feature of a gyroscope in Sigma ensures better performance compared to nautilus.
Usage
The greatness of a product doesn’t matter if the product is difficult to handle. Consumers look for a product that makes their day-to-day life easier. Dolphin sigma and nautilus are equipped with many features that help ease the task of the consumer. Both the cleaners are equipped with a top-load cartridge ensuring a mess-free cleaning. One doesn’t need to figure out the location of the filters, all they require is just removing the filter from the top part of the cleaner. The removal of the filter is not the only easy part, the cleaning of the filter is also quite easy and less time-consuming. All it requires is a rinse to remove all the collected particles from the filter. The quality of the filter container ensures long time usage of the same filter which helps in saving your money.
The capacity of the filters on both cleaners is also quite large which doesn’t require one to clean the filter frequently. The feature to control the cleaner also determines the ease of use. The sigma includes a smart control weekly timer in both the cleaners. The feature helps the user to set weekly schedules – daily, twice per week, or thrice per week, after which the rest of the work is up to the pool cleaner. The Dolphin Sigma also has a feature of connecting itself to a smartphone and after that one can go ahead with operations like spot clean, know the status of the operation, etc. the nautilus however does not include the remote control neither does it connect with a smartphone. The nautilus has a system of touch buttons. The cleaner provides a digital display panel where one can review their selections.

Conclusion
In all, both the cleaners offer a variety of features to the users. The sigma with a gyroscope and the latest technology of SmartNav navigation does not let the cleaner roam around aimlessly. The feature of the top load large cartridge makes it user-friendly. Even though the sigma has all those features the price range also increases with it, in that scenario nautilus might seem quite apt to many consumers. The nautilus also comes equipped with a navigation system of CleverClean and offers a top load cartridge. The only place where the nautilus seems to be lacking is the remote control and smartphone connectivity feature. For some consumers that might not be such a deal-breaker. It all depends on the requirement and availability of the consumer. Choosing a cleaner with certain advanced features might not be a big deal for some but many have budget constraints and can do well even without a few features. It all comes down to what the consumer desires and expects from a pool cleaner.
