Between the Dolphin Sigma and Dolphin Premier, there is no doubt that the Sigma is the more advanced robot. With more premium features, the Sigma is obviously an upgraded version of the Premier. However, I’ll choose the Premier over the Sigma for my in-ground pool and this has nothing to do with price. 

Despite being the latest model with upgraded features, when it comes to the actual job of pool cleaning and maintenance, the Dolphin Sigma doesn’t exactly out-perform the Premier.

In fact, it’s the other way round, the Premier does a better pool cleaning job because of a number of reasons. First, the Sigma robotic pool cleaners are more prone to getting stuck on pool drains than the Premier and you may have to rescue it each time by gently tugging at the power cord. 

And in spite of the advanced navigation system (SmartNAV 3.0), the Sigma misses more dirt spots than the Dolphin Premier robotic pool cleaner. Of course, you can direct its movement from the smartphone app but this requires some patience.

Finally, the Premier has multiple filter options (both filter cartridges and debris bags) for more customized cleaning while the Dolphin Sigma robotic pool cleaner comes with only one filtration system.

So, while both devices are good, the Dolphin Premier is generally the better automatic pool cleaner of the two robots.

How do these Dolphin robotic pool cleaners work?

The Dolphin Sigma and Dolphin Premier are sister products from Maytronics. These are two premium robotic pool cleaners specially designed for large in-ground pools of over 50 ft. Both of these Dolphin robots come equipped with HyperGrip rubber tracks, with which they steadily move in the pool. 

Looking for a pool cleaner with powerful suction and a high quality scrubbing brush?

Both pool cleaner robots also have dual high-speed dual scrubbing brushes for attacking and loosing all forms of dirt. A robotic pool cleaner with powerful suction, like these two Dolphin robots forces the loosened dirt particles, algae, debris and pool contaminants in a standard filter cartridge where they are trapped. 

With the quality filters, high suction power and dual scrubbing brushes, both of these Dolphin robotic pool cleaners can typically do a great job of cleaning swimming pools.

The benefits of SmartNAV technology

To ensure efficient and thorough cleaning, both the Dolphin Premier and sigma robots feature the SmartNav technology. With this, they are able to scan the pool and map out the quickest cleaning route. 

The Sigma has an upgraded version of this software and also has gyroscope sensors for advanced navigation.

The Dolphin Sigma robotic pool cleaner also has Bluetooth which connects to the MyDolphin app, with this you can control your Sigma remotely from your smartphone, this feature is absent in the Dolphin Premier. 

Both robots come with 60 ft anti-tangle swivel power cord cable and LED lights for indicating when the filter cartridges/debris bag is full. These gadgets complete a cleaning cycle in just under 3 hours and can easily maintain any large in-ground pool. 

Key features 

24-volts DC motors

Premier comes with two 24-volt DC motors while the Sigma has three 24-volt DC motors. Despite this difference, these two robots are energy efficient and run at the same 180 wattage which is an average of  $0.05/hr.

Multi-media filtration

Sigma has a large top-loader cartridge filter for trapping fine and ultra-fine dirt particles while the Premier has bottom-loader cartridge filters for ultra-fine/fine dirt particles and over-sized debris bags for leaves, twigs, sticks, and others large floating pool contaminants.

Anti-tangle swivel power cable

Both robots have the patented 60-foot anti-tangle swivel cord made from thermoplastic rubber to prevent frictional drag. This cable also rotates through 360-degrees and promotes glitch-free movement. 

SmartNav technology

Both Sigma and Premier feature the Smart-Nav system for advanced pool navigation. With this software, these robots are able to scan the pool and create a map for quick and efficient cleaning. This prevents uncoordinated movements, and saves time and energy.

HyperGrip rubber tracks

Instead of wheels, these Dolphin pool robots both use specially designed HyperGrip continuous rubber tracks. These tracks counter any loss of friction due to water and firmly plant these robots on the floors and walls of pools. This ensures that the robot moves smoothly while getting the job done.

High-speed brushes

With four high-speed spinning brushes, these robots attack and scrub off all dirt and grime. These brushes are strategically positioned (two at the front and two behind) to get to every corner of the pool.  Thanks to this scrubbing brush system, any debris, algae and dirt in the robot’s path will often be cleared without an issue.

Dolphin Sigma vs Premier — the key differences 

These Dolphin pool robots are basically the same with many similar features and benefits. They’re both designed to thoroughly clean large in-ground pools and both come with the 60-ft anti-tangle swivel cable and the SmartNav technology.

Both robots also have similar weekly timer and 4500 GPH suction rate, and these premium robots both cost over $1000, but there are differences. First, the Dolphin Premier has dual 24V DC motors while Dolphin Sigma has three 24V DC motors which deliver more power for faster cleaning. 

The Dolphin Sigma also comes with Bluetooth connectivity and a smartphone app for remote control while the Premier only has an optional remote control (which isn’t available for Sigma) and no smartphone app.

Dolphin Premier also has a caddy which you can purchase as an extra but there isn’t one for the Dolphin Sigma.

How do they perform? 

When comparing the Dolphin Premier vs the Sigma, both robots are designed to automatically clean large in-ground pool and they do it beautifully. They are able to clean the pool floor and walls, and up to the waterline. Despite being premium gadgets, these robots are not without flaws. 

First, occasionally you may find each one stuck on your pool’s raised drain, when this happens, the robot with try to work it’s way out but sometimes you may have to give it the cable a little tug to help free the robot.

The Premier has an optional remote control which isn’t very useful, while the Sigma has a mobile app for remote control. 

Manually controlling these robots can be very slow and tiring, and you’ll have to be patient with it.

Between these two, the Sigma has advanced navigation software and one extra motor, this makes it faster than the Premier, but not exactly better. Sigma gets the job done within a shorter time but Premier does a better cleaning job overall. 

In general, they live up to their expectations and offer great pool coverage, even if hey may need a little helping hand at times (whether it’s escaping the drain or going over a spot they missed on their cleaning patterns). 

They can take care of several aspects of pool maintenance for you, so a little help every once in a while isn’t usually too much of an issue.

Ease of set-up and use

Despite the advanced features and somewhat complex engineering by Maytronics, these pool robots are actually very simple machines and they require no set-up or installation. Each robot comes as a complete package with everything you’ll need to get it to do the work, they both work right out of the box. 

Simply unwind the swivel power cable, connect it to your power supply, drop the robot in your pool and turn it on.

They both have similar controls, the difference being that the Dolphin Sigma has Bluetooth and a smartphone app while Premier doesn’t. You can set each robot to clean weekly using the weekly timer.

The Sigma pool cleaner has a top-loader, and if you didn’t know, these cartridge filters tend to be much easier to remove and empty, while Premier features a bottom-loader.

Reliability 

The biggest challenge with these robots is that they tend to get stuck on pool drains and the Sigma is more prone to this than the Premier. This little quirk means you can’t trust the robot to do great job when you’re not home to watch it. 

They also aren’t excellent at cleaning pool steps and you may have to manually scrub those steps yourself, especially the shallow parts. The Sigma will likely miss some dirt spots while cleaning, so you’ll have to use the ‘spot clean’ feature in the app to get the missed spots.

For the Premier, you have to get the remote control to be able to change the robot’s direction in the pool. 

These machines are sturdily built and each have a 3-year warranty from Maytronics. However, there have been reports of breakdown shortly after purchase and unfortunately Maytronics doesn’t respond fast enough to queries and complaints.

Ongoing maintenance

These Dolphin pool cleaners are simple gadgets and they require very little maintenance. The major thing you’ll have to do as frequently as possible (after a few cleaning cycles) is to always empty the filter cartridges and rinse out the filter screen with a running water from a garden hose. 

The Sigma has a large top-loader filtration system while the Premier has bottom-loader cartridges and optional debris bags. You’ll also have to check wear and replace worn parts as soon as possible to make sure the performance of the robot isn’t compromised. Both the Sigma and Premier are backed by a 3-year quality assurance from Maytronics.

Extra purchases and ongoing costs 

All Dolphin pool cleaners come with all the essential parts and will need no extra purchases to get started with it, although you can purchase some extras for convenience.

For instance, the Dolphin Premier has a caddy and a remote control and both come at an extra costs, the Sigma has neither of these. These gadgets come both come with a 3-year warranty, you should also expect to purchase replacement parts when need be, especially for wearable parts like brushes and different cartridge filters.  

Final Thoughts comparing the Dolphin Sigma vs Premier

Apparently, Dolphin Sigma has more premium features and is an upgraded version of the Dolphin Premier. However, both pool robots provide approximately the same cleaning power, have smart-NAV technology, offer exceptional cleaning on both pool surfaces and floors, and a lot more. 

The Sigma also costs significantly higher than the Premier, which is to be expected. Despite the advanced engineering from Maytronics, these gadgets do have their quirks. But once you’re able to go around these minor drawback, you’ll have a swell time with your Dolphin pool cleaner — whichever one you decide to go for.
