Question about Roomba Robotic Floor Bagless Vacuum

1 Answer

Roomba 4000 runs ok 4 short time then stops upon hitting obstacl

My Roomba Model 4000 will run properly often for several minutes but upon hitting multiple obstacles, will shut down and sound the double beep "oh oh" that Irobot says is associated with a wheel off the floor. On average, it probably requires 10-20 obstacles before the problem occurs. I've cleaned around the wheels as best I can. I'm not sure if this is a sensor problem or perhaps a loose connection that breaks temporarily from the force associated with hitting the obstacle. It always restarts when I press the clean button. Are there service manuals available for these?

    I'm not sure what is meant by "off balance".

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

Good morning...My brand new Roomba 440 after being charged all night will run on its own for a while...but it bumps into walls or chairs and changes direction as it should, but then it stops in the middle...


Rather than try to repair it or look into it, call the dealer or take it back to him as you will invalidate your warranty if you do anything to the unit, and that is not worth it. Let the dealer worry about it.

Roomba model 4210 starts and stops after a few minutes only going in short distances and then turning allthough it hit nothing...


Inside this Roomba, the cleaning head module is clogged badly with debris. Open up your Roomba and remove all debris.

I have a Roomba, it runs for a few minutes and stops, the battery is fully charged. Any ideas?


The battery isn't able to fully charge, it just retains the proper voltage, but lacks the amperage to run because the first and last battery in the pack are dead. Battery replacement time. Try Ebay for best battery pricing.
BTW I use the nicad pack.

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

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.

"Please clean Roombas brushes"


Same thing happened to me. After "cleaning" the brushes and emptying the filter several times, I realized that the brushes were not properly secured. One of the yellow fasteners needed to be pushed closer to the middle nearer to the brushes. It was not secured properly. When I did this it fixed my problem.

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.
