Please read the intro/rules and recommendations.
Your signature block should contain your pool data - AG, IG, size, equipment installed, any special notes. If you live is especially hot areas, that burns off chlorine faster, so state where you are.
Now: Noobdy can tell you (even with all your data) which cleaner is best for you, and this group is reluctant to give specific recommendations re equipment.
You'll see a lot of post re problems with various Pentair - that is not because Pentair makes poor quality cleaners - it is because they are the most popular (or very close to most), and have a huge installed base.
Look at your pool, its bathing load, how much crud gets in, its size and shape.
The folks at the pool stores will be happy to make very specific suggestions; they will almost always suggest the one with the highest profit margin, or the one which was obsolete 2 years ago and they still haven't sold it.
Yes, I'm cynical.
So get your info into your sig block (5 lines max, please) and start reading.
p.s. welcome!
