I'm considering buying a new pool vacuum. For the past 4 years I've been using a Hayward pool vac but I'm tired of rebuilding it and it still not functioning correctly. I can't get it to stop getting hung up on the pool light, the drain at the bottom of the pool and also the corners of the steps. I'm tired of spending money on it. Has anyone had experience with The Pool Cleaner made by Poolvergnuegen?
