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

My roomba moves away from the docking station a few inches, spins in circles for a minute or so, then the red light beeps and flashes and the vacuum shuts off.

Hi, Your Roomba is experiencing the 9-beep error. This is caused by a bad component in your bump sensor. It pretty much is constantly sending a bump signal to your Roomba, which is why your Roomba keeps going backwards and circling(and never goes forward). Anyways, I had the same issue and fixed it by buying a repair kit from here.

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

My iRobot Roomba 780 just won't start moving to do the cleaning. When I press the CLEAN button it moves back from the dock, turns 180?, and then moves forward about an inch and makes the uh-oh sound...


make sure all virtual wall lighthouses are turned off. Your Roomba may be getting a signal to not proceed if the lighthouses are turned ON and facing the Roomba

560 backs out of charging base then only turns in right circles


Yes, this is known issue and if your bumper moves freely, you might be facing a sensor fault caused by poor quality of components.
Here is a guide to fix it

My roomba 530 runs in a circle and does not move forward. After 2 minutes it stops with 11 beeps and a flashing red light to the left of the power button. It has no clicking noise. Does anyone know what is...


Hey'
This means Roomba is not registering obstacles. Roomba may be stuck in one place.
Roomba may be in extremely large room, try setting up virtual walls to create smaller area.
If Roomba is not in a large room, tap Roomba's bumper to confirm it is properly working.


Hope this helps

Red sensor


If your Roomba's red "check robot" light comes on, the Roomba should also give a hi-lo warning tone, then a number of beeps. Check the number of beeps with the chart toward the end of your manual-- it should tell you what to do.

Roomba Docking Station


Probably not, unless you just have to have the docking station. My roomba always had trouble mating with my docking station so I never used it. I just plugged it directly in to will using the AC adapter.

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.
