Dolphin Sigma Review - Maytronics Best Robotic Pool Cleaner? Gyroscope, Quad Brushes, Wi-Fi, & more!

My pool's walls curve to the bottom, not sharp 90 degree joints. Will this cleaner handle those curves well? Thanks in advance!

What are your thoughts on the explore e70, compared to sigma?

How do you adjust the arm location, and why? There are several location options.

I’m between the sigma and the premier- any suggestions? Just want to know which has the best cleaning ability and I’m torn. Thanks in advance!

Are these robots capable of traversing a midwall ledge to do the walls?

What are your thoughts on Dolphin Explorer E70? Need to buy one this month was thinking about the Cigma option can't find any comparison videos on them. Thank you

Wondering if the Dolphin Sigma is better as top of line robotic wifi cleaner vs. the polaris 9650Iq. Looking for comparison on power, learning the pool for maximum coverage, cleaning the rim and tanning shelves that are raised a few feet. Also for cleaning many leaves

Just received a refurbished Sigma and so far I’m impressed. Our pool had gone about 10 days without a good cleaning. I ran one cycle with the standard filters and a second with the fine filters and it was spotless. I do have a question about the scheduling features. Aren’t these vacuums meant to be taken out of the pool and stored after each use? If so, I’m not sure how the scheduling is helpful. Could someone clarify?

Blown away by this robot !!! Glad i got it !

I live in Las Vegas were we frequently have windy days with sand blowing etc, I'm getting a rectangular shaped pool with a tanning shelf and steps would the sigma be good for me?

Does the Sigma have a full filter indicator like the Premier does?

Thanks for the videos. I was planning on going to Leslies tomorrow and buying the Polaris VRX IQ but after watching a few of your videos I'm re considering , maybe I should wait and order the Sigma ,any advice is appreciated. Iv been using the Polaris 280 for 20 years but after a complete pool remodel i think its time to upgrade to modern cleaner. Thanks Richard from California

Thanks very much for this video. I bought Sigma about a week ago based on your great review.
I do have a problem with it getting stuck on the step and bench corners of the pool.
When I contacted Maytronics support they suggested the following:
"I would like to suggest adding a third brush to the robot. The third brush in the middle helps the robot maneuver over the drain and prevent it from getting stuck on the drain.
This repair can be completed in our service in Duluth, GA. This service is covered under your warranty"

Have you heard of this kind of repair/enhancement done to Sigma?
Thank you.

I need a pool cleaner. Its a gunnite pool what are your thoughts about the Sigma you review vs the dolphin explorer e70? The pool has a in pool spa, a tanning bench as well as a sitting wall in the deep end. Also there are 2 catch basins for the long side and short side of the pool. It will need to go in there.

2 Questions for you: shopping for my first robotic pool cleaner. Q1: will I be able to put into storage my pool brush? Are robotics that good? Q2: I've seen that it is recommended to not keep robotic in the pool, to remove each time and hose off. So how does that dovetail with a programmable timer? That feature would require sustained time (days, weeks?) actually in the pool, wouldn't it? I'm very interested in the Sigma or Premier so far (in-ground pool). THANK YOU! Great videos and pro presentation!

Is there any way to change the cleaning mode? Only option is regular 2.5hr. can I make it run for 3.5 or 4hrs for a bigger pool? Doesn't seem to make sense to have a modes option with only one mode.

Is there anyway to reset how the app connects to your Wi-Fi network? We were having a difficult time getting our Wi-Fi to reach our pool area. Purchased an eero wifi extender mesh system but inside the app I don’t see a way to select a new Wi-Fi network, it just continues to connect to the one we originally set it up with? And advice would be greatly appreciated! Thanks in advance.

Is there a difference in performance if I have a fiberglass pool? Or you still recommend Sigma over Premier

I have a vacuum that picks up leaves for the pool. Does the sigma do an effective job strictly for scrubbing?

I looked at your website and it fails to mention the CC Nautilus Supreme. Which one of these apparently top models is the best? They are all about equal in price, and maybe in ?performance? Every site is reviewing these three models but nobody seems to have a concrete verdict that makes any sense - they are all over the place as to the top tiers.

Sigma or premier?
