SOURCE: My Roomba 560 does not charge - Rapid orange flash

Battery problem.If the battery is absolutely new,still it can be battery problem.But if the battery is old then replace the battery.To confirm the battery fault check the voltage of battery with meter.It should show exact volt.At least 12 volt.If the battery gets warm then the charging circuit is working but if not then the charging circuit is not working.failure is due to a failure with U2/U4 in the charging circuit. --------- For more troubleshooting,if you require service manual for your roomba model,please click on this link directly:--- http://choisirsonaspirateur.info/wp-content/uploads/2010/03/Roomba-500-Series-Service-Manual.pdf ------------

Thanks. keep updated for any more query.you can rate this solution and show your appreciation.

SOURCE: Battery temperature sensor.

1. Battery configuration is incredibly important and must be matched to the requirements of the device.

2. Battery charging is as much an art as a science. Just slapping any old power supply on a battery pack to charge it is essentially technical sue-ee-side.

Yes, the car battery folks make it look easy; but many, many millions of dollars and development hours went into that simple-looking technology just for that reason: to make it look easy.

You may have damaged the batteries and probably damaged the circuit board as well. There is a reason that companies spend millions in development. Unless you have a Master's Degree in Electrical Engineering, you should stick to factory-designed and -authorised parts.

Roomba not charging for long


More than likely needs a new battery. Does this one have a charging station? Have you cleaned Roomba lately, brushes and all.

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:

    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

    The light on my Roomba flashes amber very quickly when plugged in directly with the adapter. what does this mean? it usually flashes slower when docked.


    If Roomba senses that its battery has been significantly discharged, Roomba will enter a special 16-hour refresh charge cycle. When the 16-hour refresh charge is initiated, the CLEAN light will quickly pulse red/amber. Do not interrupt the cycle once it has begun. The 16-hour refresh charge cycle is initiated by the robot and cannot be started manually.
    For long-term storage, always remove the battery from Roomba and store in a cool, dry place. Blue or black batteries should be stored after Roomba has been used. Yellow batteries should be stored after being fully charged.
    Battery capacity reduces overtime and usually the battery will need to be replaced each year.

    Battery temperature sensor.


    you should not make your own battery and use it with roomba, or try charging it with a charger not meant for roomba, i suggest you buy the APS battery on ebay for $30 - $40. and buy a new charger from the company for $30. You can do some serious damage to the motherboard on the robot and your roomba might not work at all after that.
