Question about Roomba Robotic Floor Bagless Vacuum

1 Answer

Roomba only circles back and forth in a very small area as if something is stuck. I have cleaned and cleared all the lint and hair from all wheels and it continues in small semi-circles, moving only a few inches.

What are these 2 blinking lights on my irobot roomba?


"The Charge Indicator Light is located immediately to the right of the power button on Roomba Red and Roomba (sage). On Roomba Discovery and Discovery SE, the Charge Indicator Light is incorporated into the power button. Please refer to the table below to determine what the Charge Indicator Light is telling you.

* Pulsing Amber - Charging
* Green - Fully Charged
* Amber - Partially Discharged
* Red - Almost Fully Discharged
* Flashing Red - Fully Discharged"
At the end of a cleaning mission, Roomba will tell you if it has successfully completed it's mission or not:

GREEN = MISSION COMPLETE

YELLOW = MISSION ABANDONED (Check robot's brushes, etc.)

YELLOW RED POWER BUTTON = BATTERY DEPLETED (Scheduler Models)

RED YELLOW POWER BUTTON = BATTERY DEPLETED (Discovery Models)
number of beeps after ?uh-oh? :

No beeps: A wheel is stuck or is not touching the ground. Pick up the robot, place it down securely on the floor and touch the clean button to restart the cycle.

1 beep: The main brushes cannot turn. Turn over Roomba and remove the brush guard by pushing the two yellow tabs. Remove the brushes, clear any obstructions, and replace them again.

2 beeps: The side brush cannot turn. Turn over Roomba. Look to see if something is wrapped around the side brush. Remove the side brush with a screw driver and check for string or hair that may be wrapped around it.

3 beeps: The vacuum cannot run Remove and empty Roomba?s bin.

4 beeps: A wheel motor cannot run Your Roomba may be stuck or something may be wrapped around a wheel. Look for something wrapped around the wheels. Push them in and out and make sure they turn easily.

5 beeps: The cliff sensors have failed or are blocked. Turn over Roomba and clear any debris that might be caught underneath the front bumper in the cliff sensors. You can also use compressed air to clean them out.

6 beeps: Wheel obstruction or robot attempting to drive over an obstacle. Turn over Roomba and remove any obstructions that prevent the wheels from seating all the way up into Roomba?s body. Also, remove any obstacles that Roomba could drive over.

7 or 8 beeps: Not applicable Roomba?s beep codes do not include 7 or 8 beeps. If you are getting an error with 7 or 8 beeps, try counting again or contact iRobot Customer Care.

9 beeps: Sensor error Please contact iRobot Customer Care.

10 beeps: Roomba is stuck Pick up Roomba and start it again somewhere else. Use a virtual wall or other barrier to keep Roomba away from the
place it got stuck.

Your Roomba may be experiencing an issue where the battery is deeply discharged and may need to charge longer than the standard 3 hours. (or 7 hours if you have a standard charger)

Even with the charging light showing green (this indicates a fully charged battery) the robot is still charging. If your Roomba exhibits behavior where it charges for a short time then runs for a short time you will need to do the following.

1. Plug the charger into Roomba (if you have a home base be sure to plug directly into Roomba instead of using the home base, this will ensure the robot's charging cycle is not interrupted.)

2. After the Roomba's charging indicator goes to solid green please keep the Roomba on the charger for an additional 72 hours. (3 days)

3. After the 72 hours (3 days) has passed, turn your Roomba on and begin a normal cleaning cycle. If this works successfully it may take several uses for the battery to get back up to the performance it once had.

If this does not correct the problem, please call customer support at 877-855-8593

My Roomba 560 has started to run in small steps as if it constantly meets an obstacle and turns around in a very small circle. It advances slightly, backs slightly and turns and then does this again and...


It probably does think its met an obstacle. It could be the bump sensor switch remains pressed, one of the 4 cliff sensors on the front is dirty, or one of the 3 wheel drop sensors (left right and caster) is alarmed. Clean the sensors and your problem may resolve.

Can not charge thr battery


bbaker58,
When you press the "clean" button after charging, does the Roomba give you any audible tones? Those tones are the key to understanding failures in the 400 series. See chart below to decode those tones
If you get no tones at all, then either (1) you're not getting power from the battery to the main circuit board or (2) the main circuit board is dead. You really have to open the unit up to figure out which it is. Circuit board replacement is a pretty involved procedure since it requires disassembly of almost the entire robot. If you are brave and want to try it, replacement PCAs are available from places like www.RoboticVacParts.com. They are my favorite shop because they sell parts tha iRobot refuses to sell to consumers and they're prices always beat what iRobot charges.

Roomba just runs in small circles


i just recently had someone bring in a roomba discovery and all it would do is stay in a tight 4 tile area and go in circles. battery was fully charged and all bumpers were clear.

i took a can of air blast for cleaning computers and blasted the area on the bottom underneath the sensor and watched as several dust bunnies came flying out.gave it a few more blasts for good measure and put it back on the floor and hit power then clean buttons.

thing went in same tight circle for 2 passes then the circle got bigger for 2 more passes , blue light indicator came on and it made a straight line dash across to closed door and started following the edge and criss-crossing the room.

called the owner back in to test and it repeated the same moves when she started it and all appeared to be working normal again.

Roomba Discovery wiggles back and forth and turns over and over


No matter your model Roomba, this occurs when Roomba has gone "crazy." Its brain is no longer working properly and you can usually tell this when you've cleaned the dickens out of it a few times and the behavior is still the same. There's only one possible user fix and that is to take out the battery, hold down the power button for 20-30 seconds then reinsert the battery.

If that doesn't do the trick, IRobot might send you something called an Ozmo which you put in the data port to rewrite Roomba's brain. Unfortunately this requires it to be under warranty unless you get lucky. Good luck, all!
