![Dolphin E10 Robotic Pool [Vacuum] Cleaner - Ideal for Above Ground Swimming Pools up to 30 Feet -...](https://m.media-amazon.com/images/I/41YEKihS1ML.__AC_SR166,182___.jpg)
This isn't a cheap product by any means, so my expectations were pretty high. I previously had an AquaBot Elite for the last 3 years, which worked pretty well until one of the motors decided to stop working...conveniently just as the warranty expired. Don't get me wrong, the AB Elite was overall a good product...but this Sigma seems far superior.
While I'm only 1 week into my ownership of the Sigma, it's noticeably better than my AB Elite in:
1. Suction power - My AB Elite would tend to skip around the pool floor when it stopped and started (or turned) because its suction wasn't powerful enough compared to its drive motor.
The Sigma never loses contact with the pool floor. And, I see it sucking more debris into itself that's not directly in its path...something I didn't notice much with the AB Elite.
2. Getting stuck - I haven't seen the Sigma get stuck once yet. It put itself into a strange position on my pool steps where I was sure it would "turtle" on its back and I'd have to reset it. Nope! It corrected itself very quickly. My AB Elite would often struggle and get stuck at inside and outside corners of my pool wall and floor. It would take up to 10 minutes to correct itself, just sitting there spinning. Because the Sigma has 4 independent spinning brushes that allow it to turn in a full circle, it easily maneuvers and climbs walls at any angle.
3. Brushing the waterline - The Sigma is very impressive here as compared to my AB Elite. When it climbs and cleans the waterline, it typically goes 3-4 feet in one direction (and sometimes back again). It's very thorough. My AB Elite seemed to get lazy here and in some cycles, I noticed it didn't clean the waterline much at all. I'll be interested to see if the Sigma continues this same output over time.
4. Remote control - I didn't have remote with my AB Elite...because I didn't purchase that function. With the Sigma, the Remote App works pretty well. Like others have said, you do have to stand close to the power supply box because the Bluetooth isn't very strong. It also takes a little getting used to as there is a bit of lag between your input and response from the machine. But, overall, it's a cool feature for a quick spot clean.
5. Filters - I first ran the Sigma with the pre-installed "normal" mesh filters because I had some leaves and larger debris. Within the first 2.5 hr cycle, my pool was spotless. I then decided to run a second cycle immediately after with the Ultra Fine (corrugated) filters to see what else the Sigma would pick up. It was very impressive how much fine particles were trapped. I can see how normal maintenance with these filters can save you on chemicals.
I really don't have any criticism of the Dolphin Sigma at this time. It seems like a great product and I highly recommend it to anyone looking for a robotic pool cleaner. I did a ton of research before buying and am always skeptical of these cleaners because there are so many variations out there, and every manufacturer has many options.

Best pool robot we've ever used
We had 2 dolphin 4 pool robots over the last 9 years. They did a great job. This one is better. The cartridges are so much easier to clean and replace. This morning our pool was full of leaves and dead stems and branches. I was skeptical that the cartridge system could handle it. It did with no problem, just had to empty it after two hours the first two cycles. It was pretty weighted down as it was the first cleaning after a 5 month Arizona winter. We have a 45,000 gallon pool (24x52) and the robot cleaned the entire pool in 8 hours. Tomorrow I'll swap in the super fine filter boxes for an deeper clean. 3 year warranty plus a 3 year extended warranty. This robot will be on the job for a long time. No more pulling on the wire. The app works great and I can manually steer the robot to a shallow edge and lift it right out! Great suction. Smart coverage, nimble navigation, deep clean!
