My automation mode (using a Lutron smart switch controlling a GFCI receptacle), works great. No problems at all.
And the beauty is that anytime I want to turn on my Maytronics Robot outside of it's normal schedule, I just tell Alexa to do it. Doesn't get any easier than that.

Hi - here are some tips if you have not yet made purchase:

- do not get swivel cable if you can help it. When I needed a new cable, I switched to that from non-swivel and it constantly lost its power connection. Replacing with non-swivel solved that issue.
- do not pay extra to steer it via app. I find app useless for our model (A30i), you may as well be controlling a rover on the moon for the input delay via bluetooth.
- this thing cleans awesome and would buy again 100% if I couldn't service it
- Marina Pools might not be as responsive as you would like, but they stand behind their stuff (or bill it back to Maytronics). When the new swivel cable didn't work, I sent it back at no charge without hassle.
- get one with the extra-fine filter if you have a pool with rock waterfalls (like ours), it picks up that erosion dust even more efficiently than the pool filter.
- they will tell you it has anti-tangle technology etc etc. basically for ours, you get a few loops for every cycle, just spin the unit around counter-clockwise 5-6 times when you drop in pool after cleaning skimmer basket and you are golden.

I just had to replace some gears in mine which gave it new life, will post on its own thread as an FYI to others

If you can't reach them, how does that work?
I agree they are practically unreachable live by phone. I was trading voicemails with Seth but ultimately it did all get resolved by email/voicemail (and cable shipped back, and refund issued etc.)

I do have an alternate email, [email protected] , I would suggest to try that if the [email protected] one doesn't result in a reply.

I bought a S300i about 6-7 years ago. Loved it. When it failed I bought the S200 as opposed to spending $350 to repair. As much of a gadget-lover as I am, I'm firmly in the keep it simple school with pool robots. There is genuinely nothing the more expensive model did that my $650 S200 can't do. Mapping, bluetooth remote (used it maybe three times), scheduling - all unnecessary from my perspective. I want large capacity and reliability. And when the S200 fails, I'll buy the equivalent.

That's kinda what I thought, but to cover the pool in 2 hours, I would think it would "learn" the pool in some way other than just random patterns. I had heard it relearns it each time it is powered up. I'm trying to manage my expectations of how it works.
My 2 yr old S200 gets around most of the pool but seems to favor a few spots to revisit. It makes a valient effort to climb 2 steps and has only gotten stuck twice. Fun to watch.
If there is a layer of algae on the floor, you can watch it's tracks until water has been swirled enough to make it all invisible. My darker pebbles don't allow me to see the cleaning.
Now in summer swimming temps, I am running it every few days.

Hey all, just dropped my Dolphin Premier in the pool for the first time, thing is kind of fun to watch trucking around the bottom and sides. One issue/question: the clean filter (I have the bag filter in now) light comes on after only 30 mins or so and when I pull the unit out to clean it there is not a lot in there...some sand, and generally dirt and stuff but it is no where close to full and at this rate I'll have to clean it 5 times per cycle, which is unacceptable. I'm basically ignoring the light for now, any suggestions?
