I am a new pool owner and have bought a Dolphin Proteus DX4 pool cleaner that "cleans" walls and waterline. It does climb up on walls but randomly and gets may be 5% of the wall surface in its 2 hour run. Is that enough if vacuuming twice or thrice a week? Are all other vacuums behave the same way or are there better cleaners? I was expecting it to get much more of the the wall surface with each run.
thanks
