Been using mine for 2.5 months now. My biggest complaint is how heavy it is. Yes, it's nice to not have cables in the pool anymore, but carrying this thing back and forth between the pool and the shed gets old really fast. The light based remote this thing comes with also never worked for me. My third complaint is that there is no way to manually adjust the pool mapping. I have a few features in the pool, like stairs, column seats, endless pool equipment, that sometimes interferes with the mapping. The app is a bit confusing as well. The robot insists on making new maps every time I drop it into the pool, and I have to keep deleting them to get the one that was closest to ideal. My only hope is that this is a new product and they keep releasing updates, so maybe some of those mapping issues get worked out.
