This is my first year maintaining a pool and I just went through a SLAM. I'm seeing the value of an automated cleaner. I just came back from the store with a lil' shark by Pentair but I wanted to look into other options before I opened it. I already see the Zodiac Ranger looks like a better option. Anyway I've got a few questions and am open to suggestions. Is a suction cleaner the way to go for my small round ag pool? Would a robot be overkill? Please point me in the right direction. Definitely willing to pay more for something that is going to last and do a good job. Thanks!
