Dolphin Sigma vs Premier

Two highly-regarded Dolphin pool cleaners, the Dolphin Sigma and Dolphin Premier, are currently among the top choices for large in-ground pools. This article is a comparison between these two models, providing a review of their features and capabilities as robotic pool cleaners.

The Dolphin Sigma is the more advanced robot between the two models, it has more premium features compared to the Premier. However, when it comes to pool cleaning and maintenance, the Premier outperforms the Dolphin Sigma, due to various reasons. It’s not a matter of price, but rather the performance of the machine in cleaning the pool, we would choose the Premier over the Sigma for my in-ground pool.

The Dolphin Sigma robotic pool cleaner is more likely to get stuck on pool drains than the Premier, and you may need to manually rescue it by pulling on the power cord. Additionally, despite its advanced navigation system (SmartNAV 3.0), the Sigma tends to miss more dirt spots than the Dolphin Premier.

Although you can control its movement using a smartphone app, it requires some patience. Furthermore, the Premier offers multiple filter options for customized cleaning while the Sigma has only one filtration system. Therefore, while both devices are good, the Dolphin Premier is generally considered a better automatic pool cleaner of the two.

Dolphin Sigma Overview

A robotic pool cleaner like the Dolphin Sigma is a must-have for those who want to spend more time relaxing by the pool and less time cleaning it. This simple device can transform a large and dirty in-ground pool into a sparkling one in under 3 hours.

The Dolphin Sigma is sleekly designed with premium features, easy to understand and control, and can be directed through a smartphone app. The user-friendly application allows you to target specific areas for cleaning and control the robot’s movement in the pool.

Dolphin Premier Overview

The Dolphin Premier is a pool robot that automates pool cleaning, it’s a perfect solution for large in-ground pools that need a premium robotic pool cleaner. It’s designed to remove algae, dirt, and debris from the pool surface effectively.

Equipped with efficient and convenient features, the Dolphin Premier robotic pool cleaner provides a hassle-free way of maintaining the pool, so you can spend more time on what matters to you. It’s easy to use, no set-up, fittings, or installations are required, simply plug it in and it’s ready to use.

How do these Dolphins work?

The Dolphin Sigma and Premier are manufactured by Maytronics, specifically designed for large in-ground pools of over 50 ft. Both pool cleaner robots feature HyperGrip rubber tracks which allows them to navigate in the pool efficiently.

If you are searching for a pool cleaner with powerful suction and dual scrubbing brushes, both the Sigma and Premier are suitable options. They have dual high-speed scrubbing brushes to effectively remove dirt and debris. Additionally, the powerful suction of these robotic cleaners captures dirt, algae, debris, and other contaminants in standard filter cartridges.

Overall, the combination of quality filters, high suction power and powerful dual scrubbing brushes make the Dolphin Sigma and Premier robotic pool cleaners efficient in cleaning swimming pools.

Dolphin Sigma vs Premier — the key differences

The Dolphin Sigma and Dolphin Premier are similar pool robots, both designed for thorough cleaning of large in-ground pools, and both come with a 60-ft anti-tangle swivel cable and SmartNav technology. They have comparable weekly timers and 4500 GPH suction rates, and both cost over $1000.

However, there are some differences between the two models. The Dolphin Premier has dual 24V DC motors while the Dolphin Sigma has three 24V DC motors, which offer more power for faster cleaning. The Sigma also includes Bluetooth connectivity and a smartphone app for remote control, while the Premier only has an optional remote control and no smartphone app. Additionally, the Premier has a caddy available as an extra purchase, while the Sigma does not have this option.

So, what’s the performance?

Comparing the Dolphin Premier and Sigma, both robots are designed to automatically clean large in-ground pools and they do it efficiently. They clean the pool floor, walls and waterline. While they are premium gadgets, they may occasionally get stuck on raised pool drains, which may require a manual intervention like a pull on the cable.

The Premier has an optional remote control, which is not very useful, while the Sigma has a mobile app for remote control. Manually controlling these robots can be slow and tedious, requiring patience. The Sigma has advanced navigation software and one extra motor, making it faster than the Dolphin Premier, but not necessarily better.

The Dolphin Sigma finishes the cleaning job in a shorter time, while the Premier does a more thorough job overall. In general, both robots live up to expectations and offer complete pool coverage, but may need occasional help. They are capable of handling several aspects of pool maintenance, so the occasional help is not a significant issue.


Maytronics pool robots are easy to use despite their advanced features and complex engineering. They come fully assembled and ready to go, requiring no set-up or installation. To get started, simply connect the power supply, drop the robot in the pool and turn it on.

Both the Dolphin Sigma and Premier models have similar controls, with the Sigma offering Bluetooth and a smartphone app as an additional feature. You can also set a weekly cleaning schedule using the weekly timer. The Dolphin Sigma has a top-loading filter, which is easier to remove and empty, while the Premier has a bottom-loading filter.
