    Vac will attempt to move forward but will the quickly move backward. It continues at about the same frequency to attempt to move forward then moves backward again. Have cleaned vac and sprayed with compressed air to clear sensors.

    I had the same problem including the status light. I discovered by
    placing the front wheel on a table then turned it on and selected clean.



    The brushes weren't turning, further investigation proved that the
    brush motor was fried. Replaced motor, still having some problems.
    Whatever caused the motor to fry may still be present, but brushes do
    seem to be turning when I did the same test.

    Once a while, my one starts to move backward and turn around. Lift it and claps it couple times, most time it works normally again except this time...

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.

I turned my shop vac onto "blow" and blasted my roomba with this problem. It worked!!! I had already cleaned it thoroughly, but it needed to be blown out. My only regret is that I did it in my shop, rather than outside. It was pretty dusty.

Thanks again for the tip. Saved me $100+

Usually with ROOMBAS the culprit is dust buildup. Blowing/cleaning is the fix for that. But when all is clean and it still does the same backward dance, the problem will be one of the cliff sensor pairs have gone bad. This then requires replacing components. But first step is to always clean the roomba.

Cleaning is a temporary solution. One of the components in the bump sensor degrades over time. The permanenent solution to the 9-beep problem is to replace the component. Do-it-yourself ktis are the best way to go. There are solderless and soldered solutions available. Just need to google it.

Roomba 560 goes in circles. appears lost


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.

Backward spinning roomba


If you are lucky then one of the 4 sensors under the bumper has dust lint buildup. Blow out these areas and give your unit a good cleaning. If it still continues to do this then the bumper bar sensor should be replaced

Roomba going backwards


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.
