Stopped working after only 9 months!!!

I loved it until it quit working. No longer moves to do anything. Battery is charged, machine beeps when pressed but then doesn't start. Can't find any information online regarding this. It just doesn't move to do any mopping although it makes the proper beep sounds when I attempt to start it. Now what? I spent nearly $300 and it broke in 9 months. I used it several times a week, but was always careful with it.
