I'm looking for an automatic suction cleaner that will work with my setup. I just moved into a house with a ~20,000 gallon pool, and I consistently get sand and dirt on the bottom. No trees nearby, it's all fine debris for the most part. My parents' pool growing up was probably closer to 30,000 gallons and they had a kreepy krauly that seemed to do fine, but the trouble was keeping suction. They would need to turn the main drain off and keep the skimmer low, while having the vacuum suction all the way open. The trouble with mine is - I don't have a way to turn the skimmer down and I don't have a main drain. I have a valve that controls the vacuum suction. Would I be better served using the skimmer on full with the adapter while turning the vacuum suction (port?) off, or will that not generate enough suction?
Also, will a suction cleaner like the kreepy krauly even be the best option for my 20,000 gallon pool? Most people point to robots, but they're so expensive that I don't know if I want to pull the trigger on one considering I just converted to salt water + installed a new liner + next year I will likely have to replace the entire pump and sand filter system due to the builders using cheap knockoff equipment. I may be pushing $10,000 on all this within 2 years if I go for a robot as well. There is also a booster pump already in the system, but it sounds like it's on its last legs whenever I turn it on so I doubt it's usable for long. All input appreciated!
