I had the same problem when I renovated my kitchen. With boxes of stuff everywhere it was impossible to use Roomba. When I tried to use it again a few months later, it would stop after only a few minutes work. I had to buy a new battery which cost in excess of $100. Its better to loan it to a friend to be used than to put it into storage.

your problem is the circle dance problem or 9 beeps error
search the site and you find solutions

have you tried reset, press spot and dock together

here is the manual

Reset the Roomba: hold down "spot" and "dock/demo" for fifteen seconds, then release and listen for the tune. Then charge the Roomba overnight. The next time you run it, the unit should run longer. If not, call support and let them know you may have a battery problem. 1-877-855-8593 (I strongly encourage you to have the Roomba with you if you call.)

You need to listen to the alarm so that you can determine what Roomba's trying to tell you. The troubleshooting codes can be found here, at iRobot's website: http://tinyurl.com/md2u9p
