I am helping maintain a condo pool. Hoping to find out out how a pool vacuum works. Our pool has no vacuum hose or vacuum head. Any info you can offer will be a help given that I know nothing about this topic. 1. Do pools use the pool pump and hook into the pool plumbing system via a "port" to accomplish suction? 2. Are vacuuming systems separate from the pool's plumbing system and use their own "suction energy" source? If so, are they electrically powered from an outlet? 3. I have seen the "Pool Blaster" product which is basically a waterproof hand vac. Many reviews are good....some are awful. Anyone know this product? Are there other makers besides "Pool Blaster" of this kind of product? Does this submersible "hand vac" idea work? 4. Do pool vacuums remove the debris from the pool or simply send it to the pool filtering system? More fundamentally, our debris issue (pretty much the only debris issue) in the pool is duck waste. We have strung the pool with miles of monofilament trying to make the pool landing zone for the ducks unappealing, but it is not working all that well at keeping the ducks away. = motion sprinklers are a good idea, but not sure we can make that work in a public or condo pool = tried the floating plastic predators, but that did not work = extermination not an option = someone suggested walking a dog around the pool a few times to leave a scent that would deter the ducks. Anyone ever tried this? = hoping for a way to extract the duck debris from the pool as opposed to having it circulate to the filter (hence the vacuuming questions above). So many thanks for your thoughts on 1. the vacuuming system and 2. duck deterrents
