I'm finding it very difficult to find informative reviews online to compare brands of robotic pool cleaners. My takeaway so far is it's better to buy from a local store to get warranty service when needed. But manufacturers change model names and numbers for products sold online vs. brick and mortar. I have a 30 ft long pool with a 10 ft deep end and the skimmer at the far side works poorly, so I'm looking for good wall climbing and waterline scrubbing. Also, our neighbor has a massive oak tree that is my nemesis, so the ability to deal with acorns, twigs and leaves without constantly choking is key. I'd appreciate any feedback from pros or pool owners who love or hate a product!
