Have a good look at the side wheels do they have hair stuck around them or something?

You need to put the charging station in an easily accessible area, since the roomba doesn't know where it is if it's in another room. The roomba needs to be quite close to it to be able to detect it. When its battery runs low the roomba will zigzag around at random until it detects the charging station.

You have dead nimh (nickle metal hydride) batteries
You will need a replacement. You can test for this by removing the battery and holding the power button for 15 seconds. This will restart the charging cycle as if the battery were new.

Reset the charge cycle by removing the battery and holding power 15 seconds.

Try cleaning the battery contacts with a little rubbing alcohol or contact cleaner on a foam swab, or a bit of paper towel. Take a litle time, it doesn't always dissolve instantly. (Don't use a pink pencil eraser, it would scrub off the plating that prevents corrosion) Clean both contacts on the battery pack and both of the contacts in the Roomba. Make sure the battery is oriented correctly when you put it back in. Also clean the charging base contacts and the corresponding contacts on the Roomba itself.
I'm not sure entirely sure what you're trying to recover - the new battery pack, the old battery pack, or the Roomba itself - but since you can swap parts back and forth, you can clearly isolate the problem. The old battery pack might be rehabilitatted if you have the equipment to recondition it, but if it may not work. The new battery shouldn't have been harmed that easily.

The Roomba's internal charging system is not working. In this situation, a replacement Roomba is necessary. You can call 1-877-855-8593 to find out what your options are. There's a discount for Roomba owners who need replacement units.

did you try plugging in 560 driectly to charger then run it?
