Main Difference Between the Models
These two pool robotic cleaners represent excellent quality machines with similar features, but some differences may help you choose from the two models.
- The choice of filters in the standard package of Dolphin Premier is more vivid – 4 different filters in Dolphin Premier vs. two filters in Dolphin Sigma.
- The access to the filters is different for the two models – Premier has bottom-load, and Sigma has top-load.
- The Sigma drive is more potent as it has three DC motors while Premier only has two.
- The duration of the cleaning cycle is different. Thanks to a more powerful drive, Dolphin Sigma finishes the cycle in two and a half hours vs. three hours for Dolphin Premier.
- The Sigma pool cleaner is equipped with a gyroscope that improves the stability of a cleaner during vertical scrubbing.

Design and Dimensions
DOLPHIN Premier
- 23.58 x 19.84 x 14.02 inches
- 36.3 lbs.
- Black/blue/grey

- 35 lbs.
- White/blue
verdictTwo cleaners are almost equal in weight in dimensions. The only difference is the color which might be necessary for owners searching for a perfect fit for the pool’s color.
Motors
DOLPHIN Premier
- Twin DC Motors
- 24 volts drive
DOLPHIN Sigma
- Triple DC Motors
- 24 volts drive
verdictThe Sigma model is more powerful based on an additional motor, creating immense suction power and better stability on vertical surfaces. Even though the Premier model is a good choice compared to another model on the market.
Navigation
DOLPHIN Premier
It can clean all surfaces – horizontal and vertical up to the waterline. In addition, Smart Navigation 2.0 provides a cleaner way to avoid obstacles.
DOLPHIN Sigma
As a Premier model, it can clean floors, walls, waterlines, stairs with improved Smart Navigation 3.0 processor.
verdictThe Sigma model has improved Smart Navigation 3.0, helps orient and learn for cleaning, and performs better with each cleaning cycle.
Filtration
DOLPHIN Premier
It has four filter options: bottom-load fine cartridge filters, ultra-fine cartridge filters, an oversized fine filter bag, and disposable bags.
DOLPHIN Sigma
This model has fewer filter options: only top-loading fine cartridge filters and standard filters.
verdictThe Premier model has a great choice of filters for every owner, but if you do not prefer to exchange filters for different cleaning cycles, the choice of two filters in the Sigma model is just fine.
The other essential features are the same for both models and shows the latest achievements for robotic cleaners:
- Rubber truck tires for moving around and up the walls
- Rubber dual scrubbing brushes with powerful drives remove all dirt from the pool
- The swivel cord prevents tangling and stoppage of not sufficient length of the cable
- The number of controlling programs – each day, every second or third day
- The 90% improved energy efficiency compared to old models
Hi! I’m Markus Robertson, and water is my passion.
Five years ago, I graduated from the University of California-Los Angeles and was going to become a professional marine biologist. However, my fate had other plans for me, and due to family problems, I had to find a more stable and well-paid job. I had only one wish for my job to be connected with water.
During this period of my life, I worked as a sales manager at Olympic Pool & Spa Supplies. The job helped me learn everything about swimming pools and related pool equipment, as well as how to choose the best option and what to pay attention to.
