    • Exceeding my already high expectations
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. ... show more

    • Some tips to share and great customer service experience
The robot cleans my 30K cubic foot in-ground pool extremely thoroughly, except for the sun deck which I expected, and is easy to clean out. Here are some tips I learned along the way. 1. Buy this instead of the Dolphin CC Supreme if you have a light plaster pool. The Supreme was my first purchase and as others have described, the black plastic housing can leave black streaks on the plaster. Yes it can be scrubbed off, but it takes a lot of time and effort with a metal brush or sponge. The Sigma doesn't have this issue since it has a white plastic body. 2. The bad news; unlike this Supreme, the Signma would get stuck on the VGB main drain. The reason is that the Supreme has a center brush, whereas the Sigma only has the two front and back brushes which aren't able to push it off the drain. 3. Customer service was very responsive and pleasant by email and they first sent a list of solutions for the owner such as moving the float arms forward or drain modifications that can be purchased separately. However, these solutions either didn't work or were not available for our specific drain (MDX-R3). Some of the forums also suggest adding another float or putting teflon on the bottom but these seemed janky for a $1,500 robot. Maytronics then suggested I send the unit in to have a 3rd center brush installed! I was very happy about this as now I would have the same brush configuration as the Supreme but no streaks. I sent it to their repair center out of state and it was shipped back within a couple of weeks. The robot now works flawlessly with no issues getting stuck on the drain and no reduction in the cleaning efficiency. Although it took time and would have rather have had it work right out of the box I need to give kudos to the great Maytronics customer service team! 4. Some improvements could be made: The "massive" cartridges are actually not so large and can be filled quickly if there are a lot of leaves (usually after a storm). There is only one cleaning mode at 2.5 hours whereas the Supreme had several including a shorter 1.5 hour cycle. This seems like an unnecessary "nerf" to an expensive robot. The app is not stable and often needs to be closed and reopened before it will connect to the servers. There is no alert for a full cartridge that is available on some of their other models. Finally, ADD THE THIRD brush so other owners don't have the drain issue. ... show more

    • Too many headaches and breakdowns
When you pay $1500 sticker price for a pool cleaning robot, you expect to get a robot that functions well and lasts a long time. This has not at all been my experience. I ordered my 1st Dolphin Sigma April 27th 2023. When I got it, it did not function properly and would not climb the walls. I called customer support and they walked through troubleshooting but still nothing worked so they recommend that I return it to amazon as defective and order another. So I did that. On 5/1/2023 I ordered my 2nd Dolphin Sigma. This one worked great. But it didn't take long before it stopped functioning. In March 2024 I had to ship it into their repair office and not have it for several weeks until it got shipped back to me. I was shocked at the long list of items on the repair ticket that came back. For a robot only 10 months old... a lot of parts needed replaced. Now here we are in August and my robot hasn't been functioning well the past month (meaning i really only got 4 months out of it since last repair) so I am again going to send it in for repair. This is really burdensome when I thought I was making an investment into something that would last. Instead, it seems like a countdown until warranty expires and then from there i will be left with a paperweight. I would never buy this again and would never recommend it to anyone. ... show more
