While I was vacuuming my pool the other day, the triangular head vacuum seemed to get stuck on the bottom and it took every bit of my strength to pull it off the bottom. It does has a pretty good suction. I did notice that after the water settled, the liner was wrinkled a bit in that same spot.
Is this normal? I was thinking about getting the Diver Dave or Aquabug this summer, but what would have happened in this instance if I left the vacuum unattended?
