Looking for some expert advice. My old Polaris that I inherited from the previous home owners is falling apart, and I’m torn between getting it fixed, buying a new one, or splurging for a $1000 top of the line robot. I have a very small plunge pool with a pebble finish, so lots of nooks and crannies for algae to build up. I can’t tell you how much I hate scrubbing the pool, and if I could just get something to do it for me, it would be a great, even if I had to drop a grand or so for it. When I talked to one of the techs at my local pool store, I asked her if those things are worth it, and she looked around to make sure nobody was listening before she told me flat out, “No. they don’t scrub your pool, clean the walls, etc. It’s all a bunch of sales BS. The only thing they do is pick up leaves and debris on ghe bottom of your pool. I don’t even own one, but if it’s more convenient to you to have one instead of vacuuming by hand, just grab a cheep Polaris with a bag and you’re fine.” Is what she’s saying correct? Or will I really get some scrubbing benefit from a fancy wall climbing robot?
