My roomba goes round in circles. sometimes it stops and moves a centimeter backwards and then again it goes round in circles. if you press the ,,dock'' button it goes back to the station. if you press the ,,clean'' button, again, it goes round in circles.... the machine is cleaned, the sensors aren't covered with dirt, the weels and brushes can rotate freely.... can anybody help me??? thanks in advance franz

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

when it starts doing that hit the start button again then wait a few sec.

You have a locked wheel switch that needs to be cleared. You will need to remove the top of your roomba and find which wheel switch is clogged and clear it.

Actually, this is the Circle Dance Error. You can find a fix for it here or if you want more information about the Roomba Circle Dance Error.

Sounds like either the battery is bad or not being charged properly with subsequent loss of programming.

If your Roomba's speaker isn't working, you need a new Roomba regardless. Give a call to customer support (877-855-8593) and they'll help you out.

Txs for not helping me out unless I pay for it!!!! :-(

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.
