We have a Tiger Shark pool vac that is about 3 years old. We have never had any problem with it. Last night I put it in to clean our in-ground pool and it got hung on the steps but I didn't know it until this morning. I took it out, cleaned it, turned the handles around, turned it off and put it in the pool, turned it on a nothing. Any suggestions? I really don't have $1,000 for a new one. Thank you very much.
