The title says it all. My pool cleaner is a Hayward Navigator. Unfortunately it doesn't navigate. I've had it in Leslie's Pool Supplies. The thing used to scoot around and cleaned the whole pool pretty well. Now, however it won't steer. It just creeps into a corner and sits there. Leslie's have replaced bearings, A frames and gearbox. They don't seem able to figure out what's wrong.
I have 2 questions:
Does anyone know what's wrong with the thing?
If I need to replace it what should I get?
