Last year my vacuum kept getting stuck and by pulling it off without turning pump off realized I wrinkled my liner in 3 spots. I discovered my brush bristles on the vac were all broken down..which caused it. Should I be concerned.. fix it now or ignore the wrinkles until I spring a leak? Hopefully that wont be the case. I bought a new great white auto cleaner and have been using it this year to clean up the green so hopefully it wont wear down those wrinkled areas..
