How long does everyone run their pool cleaners? Thanks to the website my pool is crystal clear with only 3 leaves in the bottom, so looking at the bottom to know when it's all been covered by the cleaner isn't going to work. I've been throwing it in my 24' pool for 2 hours and taking it out as part of my weekly cleaning. Just curious if anyone knows how long the pattern actually takes since the Hayward website says "in minimal time".
