My Aquabot that came with the house/pool passed away 1 week before closing last year haha. At any rate, in the market for a new automatic cleaner and have been doing research. I have a 20' x 40' kidney IG, 18k gallons, 2 skimmers, 2 returns, 1 main drain, white plastics steps, 1 ladder. I get a decent amount of debri (enough to where I would need a basket filter not cartrdige filter on a bot). Based off TFP Pool School - Automatic Pool Cleaners it appears suction cleaners are okay for just small pools. I have pretty much eliminated pressure cleaners b/c they seem to be around the same price as robots (w/ booster pump). The TFP fan favorite appears to be the Dolphin S200 based off dohenys-discovery-s200-active20-triton-owners-club. I am leaning towards the Doheny Saturn as I believe it's the same as the S200 based off of this. However it's about $400 more than Doheny's version of the Kreepy Krauly and a leaf canister (I definitley don't want debri going striaght into my pump). It appears plugging a suction cleaner into the skimmer line and letting it rock and roll and cleaning out the leaf canister is the same amount of work as throwing in bot, plugging her in, and emptying/cleaning the filter. However, I trust TFP so am assuming I'm missing something? What does the process of using suction vs a robot cleaner look like? How much time doe sa robot save? How big of a pain is a suction cleaner? Would a suction cleaner even work for my the volume/size of my pool?
