Have you used the Dolphin Apollo? It must be one of the dealer specific Dolphins, because I'm not finding info online. I'm thinking of buying it from a certified dealer that I use to do my mechanical repairs. I want to replace an old Aquabot that is balky and prone to breakage. My pool has 2 closed returns, and the Aquabot gets stuck on those every time it climbs over them. If I'm not around to move it off the old return, it either breaks a plastic part or a belt. I need to watch the thing for hours to keep it from needing repairs, so i often hand vac since it is quicker. Do you think that will be a problem for other robots also? I'm thinking of the Apollo mainly because I know I can get it repaired by the dealer I already have a relationship with.
