My Polaris 360 is not moving (it appears the wheels are not turning). I already cleaned the filters (pump and mesh at the quick connect adapter). It move the little "tail" and the cleaner bag is up so, it looks like it has water flowing, but it won't move. Called my Pool company as it's under warranty, but they cannot send someone until next week. My pool is dirty as I was doing work on my patio and need to clean it before use it. Any trouble shooting advice will be appreciated.
