Head To Head Review Analysis

Cleaning Performance

Both, the Dolphin Sigma and Dolphin Premier clean your entire pool, including the pool's floor, walls, and waterline - scrubbing every inch of your pool, so you don't have to. This part of the swimming pool is vulnerable to dirt, grime, and algae buildup and accumulate. While other cleaners fall from the wall, waterline cleaning allows the robot to stay firmly planted against the wall all the way to the top. If your robot doesn't reach and clean the scum line, you'll still need to manually brush the pool afterwards each clean.

For the first time ever, the Dolphin Sigma's Dual Control Stabilizers and advanced microprocessor enable precise control and positioning of the robot. Thanks to these triple commercial grade motors, gyroscope, and dual stabilizer, the Dolphin Sigma cleans with more precision and power than previous generations of pool cleaners. The dual stabilizer acts as a counterbalance so the Sigma can effectively cling to the pool walls and waterline and even doubles as a handle. This allows Sigma to clean your pool floor, walls, and waterline (also called the scum line).

The Dolphin Premier also covers your entire pool, including the pool floor, walls, and waterline.

Filter Options

Filters are one of the most important parts of a pool cleaner. A true robotic pool cleaner doesn't just vacuum, but scrubs away and filters out microscopic particles in your water. Dolphin's ultra-fine filter captures what the standard fine filter can't, such as sand and microscopic algae, while still picking up leaves, twigs, and even small bugs.

Dolphin Sigma Fine Filter
Dolphin Sigma's Cartridge Filter

Breaking down each of their filter options, the Dolphin Sigma® includes 2 filter sets: ultra-fine Filter Cartridges and the standard filters. The Dolphin Premier includes 2 filter options as well: Standard and ultra-fine Filters. The ultra-fine Filter helps filter your pool water and removes small, microscopic algae, debris, and bacteria from your pool.The Dolphin Sigma® includes 2 Filter Cartridge Sets: ultra-fine and Standard. This gives you the ability to swap filters based on your pool's needs. If you need to clean up regular debris and leaves, you can use the fine filter cartridge. If your pool has lots of sand, algae, or even cloudy pool water, use the ultra-fine cartridges to filter and clean your pool. The Dolphin Premier also includes the ultra-fine and Standard Cartridge Filter, giving you the same ability to swap between cleaning cycles.

Ease of Use

Both robots are super simple to set up and use. To get started, simply plug the power supply into an outdoor outlet, plug the unit into the power supply, drop the unit into the water, and press start. Both robots have a weekly timer with options for daily, every other day, and every three-day cycles. The Dolphin Sigma is controlled via the myDolphin Plus App, while the Premier can be programmed via the power supply. Only the Sigma has the ability for Advanced Scheduling, which allows the robot to be set to run on specific days and times every week. So, if you want to clean Monday at 5pm and Saturday at 10am, it is as easy as the touch of a button – giving you the true automatic pool cleaner experience.

myDolphin Plus App

myDolphin Plus App

Only the Dolphin Sigma includes the myDolphin Plus App – which allows you to control the robot over Wi-Fi from anywhere. The myDolphin Plus app is available for both Apple and Android products. If you don’t have the ability to use Wi-Fi, the Sigma can still be used via a Bluetooth connection. Dolphin Sigma has Advanced Scheduling – which allows you to set the Sigma to run on specific days and times, giving you complete control. Giving you the ability to clean at 5pm Monday night while cleaning 10am on Saturday. Sigma knows and records distance travelled, time spent cleaning, gallons filtered, and kilowatts saved. The Sigma even has the Manual Drive, where you can remote control the robot right from the app. The Dolphin Premier doesn’t have the myDolphin Plus app and lacks these features.

Anti-Tangle Swivel

Both robots come with an anti-tangle swivel to minimize cord tangling. You won’t have to worry about the cord tangling, as the robots will clean with power and precision in your swimming pool. The Patented Tangle Free Swivel from Maytronics allows the robot to rotate 360 degrees without your cord getting tangled.

Warranty

A Warranty is one of the most important aspects of a pool robot. With Maytronics manufacturer warranty, the Dolphin Sigma and Dolphin Premier are both fully covered. Maytronics' limited warranty isn't pro-rated or limited to hours/cycles. The Dolphin Sigma and Dolphin Premier have the same 3-year manufacturer's warranty from Maytronics. The Dolphin Sigma and Dolphin Premier have the same 3-year manufacturer's warranty.

Which is the better pool robot?

When comparing the Sigma to the Dolphin Premier, the Dolphin Sigma has triple commercial-grade motors, a gyroscope, and the same 3-year warranty when compared to the Dolphin Premier. The Dolphin Premier will include Multi-Media, which includes an oversized leaf bag, ultra-fine filter set, and standard filter set - which is a great robot if you have a lot of leaves in your pool. You can't go wrong with either the Dolphin Sigma or Dolphin Premier, as both of them sit at the top of Maytronics' Dolphin lineup. If you want an automatic pool robot that does it all, the Dolphin Sigma may be for you.
