Question about Vacuums
If you have pets, and even if you do not, the Roomba robots use optical position sensors on the wheels to tell it how far it has turned, how far it has moved, when it needs to turn around,etc, and if those axles get wadded up with hair, lint, threads, etc, it does not know where it has been, nor where to go, orr that it is moving at all. Also make sure the front bumper is not catching on any part of the unit itself.
Make screws are snug, then pop each wheel out of it's holder except the traction tires, and clean the accumulation off of it. Make sure the traction wheels have clean axles and that there is no accumulation of fuzz, thread, hair in the gearing that drives the tires.
Also make sure the whisker switches have the whiskers clean and are not folded underneath. Also see if they are clearing the floor surface and not bent downward.
If it continues to do that, remove the battery for about 2 minutes to clear the mapping instructions (the processor memory stays live when battery power is available and the reason they discharge so fast when not in daily use and not docked. Then set it in the middle of the room and press "Super Clean" and see if it will work then.

SOURCE: Roomba turning off after 30 sec.
I was having the same problem. Roomba would run for 30 seconds and then stop. I tried everything -- then I took the small rubber brush out and removed the small nut at the end. It was packed with dust to the point that it could not turn easily. I cleaned it out and now it is working like a champ. I think the automatic shut down was just a sign that there was too much strain to turn the brushes.

After reading Solution #4 and not feeling much of any air come out of the vent, I used a flat head screwdriver to remove the grill at the back of the debris bin. I then spun the vacuum impeller around, shaking out any debris that was stuck (a little wad that had plugged it came out). I then replaced the grill and put the dirt bin back on, and my Roomba worked!

Yes, this is known issue and if your bumper moves freely, you might be facing a sensor fault caused by poor quality of components.
Here is a guide to fix it

sounds like you have two different issues here. (Possibly one common)
Clean out the cliff sensors. Under the bumper. blow it out clean. This might stop the reverse circling. The battery is either bad, or the charging circuit is bad. if battery is know good then the problem is the main board needs to be replaced. a bad battery will kill a main boards charging circuit by over working it with shorted batteries
