Dolphin Sigma Review
Dive into how the Sigma performs, its features, what's included, and how it works
What features does it have?

Waterline Cleaning
The Dolphin Sigma has waterline cleaning. This is an essential feature that you'll want when looking for a pool robot. It allows the robot to climb and reach the dirtest part of your swimming pool. Without this feature, you'll likely still need to manually clean your waterline by hand with a brush. It is one feature that you'll need and we're glad it is included with the Dolphin Sigma.
Wall Climbing
Clean like a pro. With wall coverage, the Dolphin Sigma can clean and scale your walls with precision and power. While Wall Climbing is a great feature, don't get this confused with the superior waterline cleaning feature.
What is Dolphin Sigma missing?
Leaf Bag

With leaves being a common issue, it would be safe to assume most pool robots utilize a leaf bag. Well, no so fast. Nearly every robotic pool cleaner is missing a leaf bag, except the Dolphin Premier. If you have a lot of leaves, this is the best pool robot for leaves. Not to mention the Premier's 3 year warranty, Dual Commercial Motors, and Multi-Media™ make it one of the best models of 2023.
What's included with the Dolphin Sigma?
The Dolphin Sigma includes everything you'll need. Here is what is included with the unit:
- Dolphin Sigma Unit
- 60 ft Cord with Anti-Tangle Swivel
- Programmable Weekly Timer
- Ultrafine NanoFilter™ Filters
- Standard Mesh Filters
- 3 Year Warranty
How to set up the Dolphin Sigma
Simply plug and play. All robotic pool cleaners are ready to go right out of the box. No booster pump or assembly needed. The Sigma has everything needed to get started in its box. It's that easy.
