Your bump sensors are malfunctioning. I had the same problem. The best thing to do is order a repair kit. I ordered mine from EESolutions.ca and it worked great.

Splitting the shell on Electrolux Epix 6500


With the vacuum on flipped on it's top and the bag door open, wedge a screw driver between the rear cover and the bumper. Gently tap the side of the screw driver blade toward the front of the machine. Make sure you pay very careful attention to where everything goes. It is very specific inside for reassembly.

It only spins in one place then stops


As said, if it beeps 9 times after stopping, than this is known issue and if your bumper moves freely, you might be facing a sensor fault caused by poor quality of components.

My Roomba will not move forward. It will try and spin itself and then try to move forward but then spin itself again until it stops and beeps. I tried cleaning the whole unit but it still is unable move...


Hey
is it 5xx Roomba ? is it 9 beep that it sounds ?

Please look for other same problem posted here ;-)
You are probably facing a bumper sensor issue.
Try to clean the bumper first and if this goes on, either call iRobot service, or
take a look at this page for the step by step 9 beep fix.

IRobot Roomba Discovery not moving across room.


I had the same kind of problem with my model 400 today...after starting it and having it go in a circle for 30 seconds or so it would finally run into something and then back up a few inches, turn, then go forward a few inches, then back up a few inches, turn, then go forward a few inches, etc., etc.. I tried cleaning off the four pairs of sensors under the bumper and blowing out various things underneath (by mouth since I didn't have any canned compressed air). It didn't really help. It then occurred to me that I had a leaf blower! I put the Roomba upside down on the grass, put the leaf blower on high, and blew at it from all directions and up close. More dust came out than I thought would. It has been running normally now for the last 45 minutes.
