versus Dolphin Sigma®

Cleaning Performance

While the Dolphin Sigma and Dolphin ADVANTAGE are both designed to clean your pool's floor and walls, only the Dolphin Sigma provides full pool coverage as it is able to clean every inch of your pool - including the waterline. The Dolphin ADVANTAGE will miss the waterline, as it will only cover the pool floor and walls. 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).

Dolphin Sigma's Powerful Waterline Cleaning

The Dolphin ADVANTAGE will only cover pool floors and walls, as the ADVANTAGE does not include the ability to reach the tile line. The Dolphin ADVANTAGE will clean your pool floor and walls, but expect it to miss your waterline entirely.

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'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 ADVANTAGE includes only one filter option, the standard filter, but won't include the ultra-fine Filter. The ultra-fine Filter helps filter your pool water and removes small, microscopic algae, debris, and bacteria from your pool. The ADVANTAGE comes with one filter option included. While, 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.

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 ADVANTAGE 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 ADVANTAGE doesn’t have the myDolphin Plus app and lacks these features.

Anti-Tangle Swivel

Only the Dolphin Sigma includes Maytronics’ patented anti-tangle swivel, which helps minimize cord tangling. The Tangle Free Swivel from Maytronics allows the robot to rotate 360 degrees without your cord getting tangled. Without it, the ADVANTAGE's cord can get tangled and caught up in your pool – leaving a tangled mess.
