Question about iRobot Roomba Red 4100 Bagless Robotic Vacuum

Roomba Red Problem

Unit worked well until I sent it on a mission to clean after kids were in the house. The following day the unit started waddling like a ruptured duck, it would go forward about a foot then make a partial turn, forward another foot, partial turn. This behavior continued within about a two foot square area until the unit stopped.

I could tap the bumper and the unit would turn and start circling, then would lock in the motion described above.

I did take the unit apart (field stripped it) and cleaned all surfaces with a dry soft cloth and all of the sensors with a Q-Tip (this included the wheels).

Any suggestions?

Thanks: RAnderson

Re: Roomba Red Problem

Mine did a similar thing. I kept trying to use it anyway, when it made a violent jerk (I thought it had broken something) and it started to work again.

Have you tried pressing both buttons at the same time to make it go straight ahead? It might work.

Roomba 4210 won't start

  • Lift Roomba off the floor and place it in the center of the room and restart the clean cycle.
  • If Roomba did not resume cleaning, lift Roomba and turn it over.* Inspect the Side Wheels for dirt or obstructions.
  • Test the Side Wheels by pushing them in and out and making sure they rotate freely. Place Roomba in the center of the room and restart the clean cycle

    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:


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


    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

    Clicking sound and wont **** up dirt, says clean brushes and i did, and still doesnt work

    The brush deck should raise depending on the floor surface the Roomba is cleaning. Remove the dust bin, send the Roomba on a cleaning mission and observe through the dust bin opening whether the brushes are turning.

    I have cleaned & cleaned this thing! It runs for about 2 mins & stops, says "Clean Brushes"! and now it's very noticeable it's not picking up well... but is picking up a bit. I take the dust bin...

    Ok, this is a "Brush Height Adjustment" issue. It will probably work great on a hard surface but on carpet the brushes bog. If you've taken the unit apart it again. When you do, you'll see a String which allows the brushes to "Float" on different surface heights. Loosen the screw a little and pull a bit more string through. Re Tighten the screw and put it together enough for a test run. Now reset the roomba.To reset the Roomba, power the Roomba on, and press the Spot, and Dock buttons together for at least 8 seconds. Until it plays a tune. The clock, and any schedule is erased at this time. Try running the Roomba with the dust bin removed to see the brushes spin easier.

    Second method, is taking off the bottom cover, and removing the battery. While it's removed, and not plugged into the charger, press the clean button for at least 20 seconds. This will erase the memory. Replace battery, and cover. Run the Roomba to see if the brushes start to spin. You can also remove the brush housing by removing the 4 screws and reseating it, to see if it was a bad connection, since you have the bottom cover off.

    My Roomba will not charge, the light on the charger is on and when you plug in the roomba the light goes out and nothing happens. Can anyone help. It is a Discovery Model 4210

    Are you using the home base or are you plugging the charger directly into the Roomba? If you are using the base, give plugging directly into the unit a try.

    You might also try resetting the battery. With the battery out of the unit, press and hold the power button for 30 seconds or so. After this is done, plug the charger directly into the unit, and let it charge for 3 days (no kidding, 3 days). After that, if you still have issues, it might be time for a new battery, or time to send the little guy in for repair.

    Problems with roomba 530

    before taking apart your Roomba read this!!! First to see if it is a defect or really the brushes, take the brusehs out and run roomba with out them. If you still hear the clicking/ thumping then try taking it apart or call roomba. But if the clicking/ thumping goes away when the brushes are out you're in luck! Take the brushes. The brushes have little yellow nubs... those come out. pull them out, and you will see a lot of hair waiting for you. clean all of the hair out ( tweezers are wonderful for this). Once they are cleaned out put the yellow nubs back on. Put your brushes back in and you're Roomba will be back to business in no time!!!

    No suction

    Roomba does much of its cleaning by the brush and roller on the bottom, but an important part is the little fan at the back of the debris bin which provides 100% of the 'suction.'
    First, take off the vent cover on the back of the debris compartment and start Roomba on a mission. You will see the little turbine spin (if it's working) and probably a little dust cloud will come out.
    It may not be working at best efficiency, however, because dirt gets sucked into the housing and blocks much of the air flow. Now that you know what the fan/turbine looks like (it's quite small, only the size of two stacked silver dollars), peer down into the larger opening of the debris bin and view the turbine from the other side. Chances are there's some crud stuck down there which is impeding air flow. (There's a hollow part of the turbine where the air is sucked into before being expelled out the back, that's probably filled with pet hair/dust/etc.) Clean that out using a long knife, chopsticks, or anything else that can reach down in there. Bang the dust bin down (lightly) to dislodge any more hair that's up there and continue cleaning until it's all gone.
    I've had 3 Roomba's and they all get hair stuck up there. I only have to do this once a year or so (multi-cat and dog household here!) but it makes all the difference in the world.

    Mine did the same thing. I'm going to send it back for a warranty repair.

    Same thing happened to me, I called the company, and they told me to remove the battery, press the on button for 5 seconds, which clears the system, replace the battery and do a long charge 12 hours. I'm in the process of doing that now.
