Question about iRobot Roomba 4210 Bagless Robotic Vacuum

Roomba going backwards

Ours goes backwards ONLY now... was stopping and starting then dying... now it only goes backwards and rides up onto the furniture and stops.
Did the fix mean sending it back and getting a new one?

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.

Check all the wheels to make sure that they are ok. Check the sensors on the bottom and make sure they are all clean.

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

Backs up spins in circles, then red light flashes and beeps


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

Running backwards in circles.


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.
