Hi I am new and had two questions. My lake shaped pool has wrinkles and seams in the liner. Will I be risking vinyl liner tears/leaks if I use a bot that is self contained to clean my pool? We did not cover this winter and there is debris that I can't seem to lift and skim. It isn't time to open yet and the pump is stored. I float a chlorine dispenser to keep the water clear until opening. Otherwise it is a salt pool. I posted another thread asking if my kids could sit in a bromine spa and then dive into a chlorine pool.
