My pool is surrounded by landscape gravel, and sometimes gravel ends up in the pool. I was thinking of trying a Kreepy Krauly cleaner, and I wonder if anyone knows what happens when one of these encounters a piece of gravel. My Hayward Navigator picks up the gravel and then it jams the moving parts, so I have to pull it out of the water and open it up to remove the gravel. Since I have to watch it to see if it gets stuck it doesn't work very well as an unattended cleaner. Also, the pebble surface hides the gravel so I don't know it's there until the cleaner gets stuck on it.
