Like other high-quality automated pool cleaners, the Dolphi Sigma doesn’t use wheels but rather uses tracks. This is due to the fact that tracks offer better traction and control in the water than wheels can. It also gives the Dolphin Sigma the ability to easily navigate obstacles.
However, Sigma has its HyperGrip tracks, which are uncommon in today’s market as they work separate from one another. With this technology, your Dolphin Sigma can turn its tracks in opposite directions, which then gives the unit the ability to turn around no matter where it is.
SmartNav and Mapping Navigation
Many Dolphin robot pool cleaners make use of SmartNav and mapping navigation. However, Sigma offers the latest and greatest with this technology, which provides a better and more precise cleaning. The robot pool cleaner will remember the size, contour, and shape of your pool, calculating the best pattern for cleaning your pool.
Instead of moving around your pool aimlessly, the Dolphin Simga follows a specific path which cleans every spot. Plus, SmartNav tells the unit where it’s already been, so it won’t spend time going over areas multiple times.
Dual brushes for scrubbing
Dirt and algae are always a problem on the floors and walls of your pool. That’s why the Dolphin Sigma has dual high-RPM brushes. These brushes get even the toughest spots in your pool clean. Each brush is split, which means you’re getting four brushes in total. There are two on the front of the unit and two on the back.
You won’t get a remote with the Dolphin Sigma, but you don’t have to have one. You can use your phone to control your pool cleaner through the MyDolphin app. Download and install it to your smartphone and use the app to move your unit around the pool.
A weekly timer allows you to get your pool clean even when you’re not at home. All you need to do is choose the schedule that works for you: every day, twice a week, or three times a week. Then just let the Dolphin Sigma get to work. Be sure you leave the device in the water so it can start automatically cleaning.
Dual oversized top-loading filters
The Dolphin Sigma comes with two filter types. One collects large contaminants like small rocks, acorns, leaves, and twigs, while the other is for fine debris like dust, dirt, and sand. These top-loading filters are top-loading, so they’re easy to remove, clean, and replace. Plus, they don’t require you do turn the unit over when you’re ready to wash them.
Most robotic pool cleaners use one motor and even the premium ones use two. However, only a rare few boast three motors on the unit as the Dolphin Sigma does. This makes the unit one of the most powerful on the market. It rarely gets stuck and moves quickly and easily in your pool.
Pros of the Dolphin Sigma

What Others Are Saying
Most users say that the Dolphin Sigma is a solid pool cleaner that is easy to use right out of the box. It takes 15-20 minutes to get it set up and running, so you won’t experience much hassle or frustration with installation. They boast that the filters are simple to remove and replace while the top-loading panel is a nice feature.
Others talk about how well it cleans the walls and waterlines of their pools. It offers impressive stability and suction and gets your pool clean each time it runs. Additionally, users like that the device doesn’t use a lot of energy and does a better job than pressure and side cleaners.
The Dolphin Sigma has its share of drawbacks as well. Some users report that the mobile app is clunky and not intuitive, which makes for a poor experience when controlling the device in the water. Additionally, users report that the Sigma occasionally get stuck on the drain in the bottom of the pool, something that they say shouldn’t happen with such an expensive unit.
