Further down the page, you’ll find some explanations regarding the key similarities and differences between the Dolphin Premier and the Dolphin Sigma.
But before checking out explanations regarding their power, portability, and features, here’s a table that summarizes the main technical summary sheet for these 2 robotic pool cleaner:
Portability Comparison
Premier and Sigma are in the same Dolphin line of robots, so they are designed with quite similar dimensions. While Dolphin Premier’s measurements are 23.5 x 19.5 x 14 inches, the corresponding Sigma parameters are 23 x 19.5 x 13.5 inches. Thus, in the same amount of time, the two can clean an almost equal area.
However, the 37.2 pounds of the premier product is higher than Sigma’s 35 pounds. Therefore, you may have difficulty taking Sigma robots out of the pool.
Power Comparison
Both Premier and Sigma have dual brushes with 2 front and 2 rear brushes. Therefore, they have access to even the hardest-to-reach corners of the pool. Also, Sigma is further improved with a brush in the center to increase cleaning efficiency. With this design, you will easily remove the biofilm clinging to the pool surface before being sucked into the filter chamber.
These two devices have built-in filters to classify trash and LED warnings when the trash bin is full. While Premier operates through 4 different types of filters, Sigma’s is simpler with 2 classes. One for small debris and the other is a large cartridge filter for large trash such as leaves or twigs. Therefore, you will reduce the number of times you dump, clean, or replace Sigma’s garbage bag.
Also, the manufacturer has equipped these two devices with the anti-tangle rotating cord. When operating, the machine rotates 360 degrees in a circle. This design will prevent the robot from being retained in specific locations under the pool, such as tree clusters or lake decorations.
Dolphin Sigma and Premier are integrated with rubber grooves to help them quickly climb walls or stairs.
Another big difference between Sigma the Premier is the gyroscope. As a result, Dolphin sigma is capable of accurately locating dirty locations and needs cleaning. Also, Sigma has three motors that increase suction power and suction speed so that the swimming pool will be cleaner than Premier.
Features Comparison
Both models work thanks to the SmartNav system. After entering the water, this system automatically scans the space and gives suggestions for the best cleaning plan. However, Sigma’s version is upgraded with the ability to operate via Bluetooth on the MyDolphin app. As a result, the phone can act as a Sigma remote while you need to direct the Premier via its buttons.
The scheduling feature of these robots is also appreciated. As they allow pre-programmed cleaning schedules daily or two to three times per week, this also saves you from getting Premier up often to act.
