Head To Head Review Analysis
Both, the Dolphin Sigma and Dolphin Proteus DX4 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 Proteus DX4 also covers your entire pool, including the pool floor, walls, and waterline.
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.
Breaking down each of their filter options, the Dolphin Sigma® includes 2 filter sets: ultra-fine Filter Cartridges and the standard filters. The Dolphin Proteus DX4 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 Proteus DX4 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.
The Dolphin Sigma includes:
- Standard Cartridge Filter Set
- ultra-fine Cartridge Filter Set

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 Proteus DX4 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

The Sigma even has the Manual Drive, where you can remote control the robot right from the app. The Dolphin Proteus DX4 doesn’t have the myDolphin Plus app and lacks these features.
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.
