I've got a Polaris 280 that still works, but stuff keeps breaking on it regularly and I have to keep replacing parts. The Pentair parts are stupid expensive, so I tend to just buy third party Amazon parts. It's still working and the RPM calibrated and all that, but it's just too chaotic for my taste. The shallow end of my pool has a gigantic blue oak overhanging it, and acorn season just started. I've been having to run it 4-6 hours a day just to keep the shallow end clean, changing the bags 1-2 times per day. It's really annoying. Plus, the Amazon knockoff tail I just put on is constantly spraying water everywhere when it comes up near the waterline. Even over my fence into the neighbors pool, haha.
So I just picked up an S1 Pro on sale for $879 during Prime Day simply because my buddy has one and says it's been pretty good. I just received it yesterday, and I honestly wasn't impressed with the Auto mode much. When it did the walls, it would do counter-clockwise rotations of my pool, but it would consistently skip a the same quarter of the walls in my shallow end for some reason, as well as sometimes randomly skipping a few feet. I kinda wish Auto started with the floor and used the last half of the battery for the walls since the floor gets the most debris and that's usually what I wanted it to clean first.
Today, I set it to floor mode and it seemed to do a much better, programmatic clean. It got all the acorns and junk without any issues during a 3-hour shift. My pool is a blobby design, with rounded corners and a step in the deep end and by the waterfall. These tend to make it turn a bit when backing down the wall, which might be why it seems to skip parts. Putting it in wall mode still skips the same quarter of my walls unfortunately.
I do like the large basket, as I don't have to empty it every time like my 280's bag during acorn season. I'm actually shocked at how much other Crud and dog hair it picks up compared with the 280 as well. Did anyone buy a second basket or filter to have a spare? With my two Bettas (one is half broken of course lol, and the other is it's replacement), I have 4 baskets total, so I can pull the two baskets and let the debris dry off before I dump it.
Being able to run it alongside my Bettas without them getting stuck on a hose constantly is nice though.
My biggest LOL is the fact that wall mode must be engaged from the app. This seems to suggest that they designed the hardware, and a week after release they realized that they forgot to put a LED indicator for wall mode, along with a way to select it, so they had to just add it to the app as a bandaid.
Overall, I'm at like a 6.5/10 on my enthusiasm for it, which isn't great for almost a $900 robot. My kids immediately wanted to make rocket ships out of the cardboard boxes it came in, and I told them no just in case I wanted to return it.
