As amazing as Roombas are, they are machines and will inevitably come across an issue. No matter the issue, iRobot has come up with a helpful system of error codes to troubleshoot any problem.

In this post, we share with you the complete Roomba error code troubleshooting guide. No matter the problem, you should be able to find a solution in this comprehensive article.

You can use the quick navigation tab to go to a specific Roomba error code.

IMPORTANT: A Roomba  runtime error is different from a Roomba charging error. If your Roomba is experiencing an error while charging, please go to the charging error troubleshooting guide right here.

Roomba Error Code Troubleshooting

A Roomba without Wi-Fi capabilities will stop and tell you something is wrong with a two-tone “uh-oh” sound followed by a narrated voice. Error messages can be repeated by pressing the bumper or the CLEAN button.

A Wi-Fi connected Roomba will display the error in the iRobot HOME App through push notifications. Tap the troubleshooting icon for additional information. Roomba will play a two-tone “uh-oh” sound, followed by a narrated voice. Select models will display a blinking  troubleshooting indicator.

The troubleshooting guide below applies to all Roomba models. Newer Roomba models will have more error code possibilities than older versions because they employ better technology.

Please use the information below to troubleshoot a Roomba error code:

Error 1: Roomba is stuck (left wheel)

Error 1 means the Roomba’s left wheel is hanging down or the Roomba is stuck.

If this is the case, lift your robot off the floor, place it in the center of the room, and restart the clean cycle. If this error occurred on a flat surface, check the wheels for obstructions.

Push the wheels up and down several times and shake out any debris that may be trapped in the wheel well.

Gently turn both wheels by hand, making sure they turn freely, and each wheel displays the same amount of resistance. Ensure the Roomba’s wheels are firmly on the floor, then start the Roomba in a new location.

Error 2: Main brushes cannot turn

Error 2 means that the Roomba’s main brushes or extractors cannot turn.

Remove the main brush roller and remove hair and debris that may have accumulated and become tangled. Ensure hair and debris is removed from the square and hex pegs of the extractors as well.

Remove the extractor caps. Ensure any hair or debris that has collected on or underneath the caps, as well as around the metal axles, has been removed. Last but not least, ensure the vacuum path is clear.

Error 13: Both wheels on uneven surface

Error 13 means the Roomba is on an obstacle or an uneven surface and a side wheel is stuck.

If this is the case, lift your robot off the floor, place it in the center of the room and restart the clean cycle. If this error occurred on a flat surface, check the wheels for obstructions.

Push the wheels up and down several times and shake out any debris that may be trapped in the wheel well.

Gently turn both wheels by hand, making sure they turn freely, and each wheel displays the same amount of resistance. Ensure the Roomba’s wheels are firmly on the floor, then start the Roomba in a new location.

Inspect the front caster wheel on the robot to ensure it is free of any debris.

Error 14: Roomba does not detect bin

Error 14 means the Roomba is not detecting an installed bin or the bin has a bad connection to the robot.

If this is the case, confirm the filter and the bin are installed properly.

Remove and reinstall the bin to ensure a good connection. Please check the metal bin contacts and wipe them on both the robot and the bin with a clean, dry cloth.

Error 15: Internal board error

Error 15 means the Roomba is experiencing internal board error. 

This error happens only to Roomba models with smart maps and can happen periodically. A few things can trigger it. Often, Error 15 means your robot experienced an internal error and was able to take care of itself. It's just letting you know about that afterwards.

For example, if the battery is removed and then reinserted into your robot, upon power up, your robot will signal Error 15 (this is expected behavior, and there is nothing wrong with your robot).

However, if Error 15 is happening on every cleaning job, and is interfering with your ability to use the Roomba, you can try the following troubleshooting steps:

1. First, revert your Smart Map to a previous version by going into your History and viewing your Clean Map reports. At this point, simply find a map you like from a previous cleaning job and select the overflow menu in the top right corner. Select "Update Smart Maps" to complete this process.
2. If the error persists, try remapping your home by deleting all of your Smart Maps and starting a new one. You can do so by viewing the maps you'd like to delete, tapping the three (3) horizontal dots icon, and then choosing "Delete map".
3. At this point, you can try rebooting your robot. To do so, press and hold its button for 9 seconds, and then release it. The light ring will then swirl clockwise in white. This swirling pattern, which can last for up to a minute and a half, means that your robot is booting up. The reboot procedure is complete when the light ring shuts off.
4. If none of these steps work and Error 15 persists, you can perform a full factory reset. You can learn how to perform the correct factory reset right here.

Error 16: Roomba is tilted or the bumper is dislodged

Error 16 means the Roomba is not able to start cleaning because it is tilted or the bumper is possibly dislodged from the robot. If the bumper is dislodged, push the bottom of the bumper in this area in, and up towards the top of the robot. You will hear a click when it snaps back into place.

After, the bottom of the bumper is in place, press the top of the bumper in the dislodged area in and down towards the bottom of the robot. You will hear a click when it snaps back into place.

Tap on the bumper to ensure it moves freely.

If the bumper is not dislodged from the robot, move the Roomba to a flat surface then press the Clean button to restart. Avoid moving the robot when pressing the button.

If the Roomba says this message on a flat surface, reboot the robot.

Error 17: Navigation problem

Error 17 means the Roomba has entered an unknown area and got lost while cleaning and unable to return to Home Base. It can also mean the Roomba cannot complete and has cancelled its cleaning job.

Here’s how to troubleshoot error 17:

• Ensure there were no changes to the environment during the cleaning cycle like a closed door or moved furniture.
• The space is too large to be completed in a single cleaning run.
• The carpet to be cleaned is too thick.
• It is possible for a Roomba to drive over transitions, such as doorway thresholds, that it cannot drive over again when trying to leave the area.
• Ensure the house has adequate light (daylight or dim lighting should be sufficient) for Roomba to navigate. Extremely dark rooms can obscure the localization camera and cause problems with navigation and coverage.
• Excessive clutter can contribute to this error. Clear any cluttered areas.
• Ensure the camera is clear of any dust or debris. Wipe the clear window using a microfiber or soft cotton cloth that has been lightly dampened with water or a screen cleaning solution.
• There may be debris on the Floor Tracking Sensor. Turn the Roomba over and use a clean, dry microfiber or soft cotton cloth to wipe any debris that has accumulated in the round Floor Tracking Sensor opening on the right side of the bottom surface. Do not spray cleaning solution directly into the sensor opening.
• There is an issue with the robot (e.g., a loose caster wheel) which requires maintenance.

Error 18: Docking problem

Error 18 means the cleaning is complete, but the Roomba was unable to dock onto the Home Base. Put simply, Roomba cannot return to the Home Base or starting position.

Please check the Home Base and charging contacts, then do the following:

• Ensure the Home Base did not get unplugged, moved, or rotated during the cleaning cycle.
• The charging contacts on both the Home Base and robot should be clear of residue or debris. Use a clean lightly dampened melamine foam such as a Magic Eraser to remove any residue or debris that may have built up. The power indicator on the Home Base will illuminate when your Roomba is charging.
• Use a clean dry cloth to clean the front facing camera, and the Visual Docking Target on the Clean Base or Home Base.
• Ensure there is no clutter around or near the Home Base.
• The position of the Home Base is on a hard, level surface against a wall. Your Roomba should have a clear path to the Home Base and the Home Base should be at least 4 ft (1.2 m) from any stairs.
• Ensure there are no obstructions (e.g., stickers, tape, or paint) on the bumper or on the Home Base.
• Please check if Your Roomba can detect the Home Base.
• If your Roomba is not starting on a Home Base, ensure there are no obstacles in front of the starting position. This will prevent Your Roomba from being able to return to the original starting position when the cleaning cycle is complete.

Error 19: Undocking problem

Error 19 means your Roomba is experiencing an issue undocking from the Home Base. Clear any obstacles that may be in front or around the Home Base, then press the button.

If the message persists, please perform a reboot on the Roomba and the Home Base, then start your Roomba from the Home Base. Environmental interference may prevent your Roomba from navigating as expected.

If the issue persists, try to start Roomba off the Home Base. Doing so may cause Roomba to provide a different Error Message. Use the to troubleshoot the Error Roomba presents.

Error 41: Mission timed out before completion

Error 41 means your Roomba timed out during a cleaning mission.

This error could occur due to the following reasons:

1. The cleaning job took too long for your Roomba to complete and the robot did not pause or perform a recharge and resume cycle. This could happen if the robot ran over four (4) hours without either occurring. Please place Roomba back onto the Home Base to let the robot charge, and then attempt another cleaning job.
2. Roomba reached the limit for the room size area it is able to cover during a cleaning job. The robot can cover a certain area on one level of the home. If this happens, place the robot and Home Base into the area of the home where the robot is unable to reach and start a new cleaning mission. Doing so you can also create and eventually save a new map for that area. Anytime it is desired for the robot to clean this area of the home, the robot will need to be moved and fully charged.
3. The robot did not perform any wall following within 15 minutes of beginning the cleaning job. Ensure the robot is navigating around the home as intended and not stuck in an area such as under a table with multiple chairs.
4. The robot did not perform edge cleaning within the duration of the cleaning job with edge cleaning activated in the iRobot HOME App. Ensure the robot is navigating around the home as intended and not trapped in a tight space such as under a table with multiple chairs.

Error 42: Failed to re-localize when direct cleaning

Error 42 means that your Roomba failed to re-localize during a direct cleaning job using Smart Maps and the map may also appear to not look correct in the app.

This error could occur due to the following reasons:

• Changes to the environment during the cleaning cycle (i.e. closed door, moved furniture).
• It is possible for the Roomba to drive over transitions, such as doorway thresholds, that it cannot drive over again to leave the area.
• Not enough adequate lighting (daylight or dim lighting is sufficient) for Roomba to navigate. Extremely dark rooms could obscure the localization camera and cause problems with navigation.
• Excessive clutter could contribute to this error. Clear cluttered areas.
• Camera covered with dust or debris. If so, wipe the clear window on the top surface using a microfiber or cloth that has been lightly dampened with water or a screen cleaning solution.
• Roomba was picked up and moved to another location while cleaning.

Please ensure there were no changes or edits to your Smart Map. Place your Roomba back onto the Home Base and attempt another direct cleaning job.

Error 43: Roomba started in Home Base Keep Out Zone

Error 43 means your Roomba started a job in a Keep-out Zone.

The robot places a small keep-out zone around the Home Base by default. Move your Roomba to a new location, then press the CLEAN button to restart the mission.

Error 46: Robot ended mission with low battery not on dock

Error 46 means that your Roomba's battery is low and needs to charge. Place your Roomba on the Home Base until fully charged. You can use the iRobot HOME app to view charging status.

Error 47: Invalid robot calibration

Error 47 means your Roomba is experiencing an internal error.

A robot reboot should resolve this issue. If the error persists, please contact iRobot Customer Care.

Error 48: Invalid robot calibration (Roomba’s path)

Error 48 means your Roomba’s path is not properly calibrated.

If your Roomba says "couldn't get to the room you asked it to clean. Please clear the path and try again." Please make sure there are no obstacles that are preventing Roomba from navigating from room to room within the cleaning area.

Ensure that the Imprint™ Smart Map looks like your cleaning area and that all desired cleaning areas are connected within the Smart Map.

Error 66: Memory limit reached

Error 66 means your Roomba has run out of memory during a cleaning mission.

You may see the robot return to its Home Base and reboot itself.

The Light Ring will swirl white and the robot will beep. If this occurs, ensure that your robot is provisioned to the iRobot HOME App before starting a cleaning job. Please go to Setting up your Wi-Fi Connected Robot with the iRobot HOME App to connect to the app.

Once your robot is connected to the app, as your robot maps out space in your home it is continually adding information to its memory. If the space the robot is mapping out is too large for the robot's memory, the robot will eventually run out of memory, head back to the home base and then report this error message.

The robot will then automatically reboot while on the home base to clear the memory.

If your robot continues with this error after rebooting, perform the following steps:

• Create a new Smart Map with smaller sections of the house and use directed room cleaning only once the map is saved.
• If multiple maps are saved in the app, delete any unused maps as this will free up memory.

If the robot does not perform an automatic reboot after docking onto the Home Base, please reboot the robot manually. If the message persists, please contact iRobot Customer Care.

Error 68: Camera failed during cleaning job

Error 68 means an error occurred with the Roomba’s camera during cleaning.

If your Roomba reports an error 68, this means the robot is not receiving data from the camera which will cause the robot to not navigate your home properly.

Should this error occur, place the robot back onto the home base and perform a robot reboot; this should clear the error and you will be able to perform another cleaning job.

If the message persists, please contact iRobot Customer Care.

Error 74: Area limit cleaned reached

Error 74 means your Roomba has stopped during a cleaning mission because it has reached the limit for the maximum area it can cover during a cleaning job.

This can happen because the Roomba can cover a certain area on one level of the home.

Also, the area covered is dependent upon a few factors including flooring type and furniture.

If you receive this error, place the Roomba and the Home Base in the area of the home where the robot was unable to reach. Start a new cleaning mission.

If error 74 continues after relocating your Roomba, perform a reboot to clear the error. If the message persists after the reboot, contact iRobot Customer Care.

If you own a Roomba with Imprint™ Smart Mapping capabilities, you have options for creating and saving a new map for that area, and for replacing a Smart Map with a recent Clean Map. Anytime it is desired for the robot to clean this area of the home, the robot will need to be moved and fully charged.

Error 75: Stuck around obstacles

Error 75 means your Roomba timed out during a cleaning mission because it is stuck around obstacles.

This can happen because the Roomba did not perform any wall following within 15 minutes of beginning the cleaning job. Ensure the robot is navigating around the home as intended and not stuck in an area such as under a table with multiple chairs. Perform robot reboot if issue persists after relocating your robot.

Error 88: Roomba cannot safely move backwards

Error 88 means your Roomba has determined it can no longer safely back up (reverse).

The error occurs on a Roomba that is not equipped with rear cliff sensors when it is unable to back up any further due to a perceived safety issue. There is a limited distance that the robot can safely back up to ensure it does not fall backward down a cliff.

The error can also occur if the Roomba gets stuck on a threshold, hung up near a chair, or gets into a situation where the bumper is hit when it does see an actual cliff.

Spinning in place depletes the amount of distance that the robot can back up.

To solve this error, move the Roomba to a new nearby location and press the button to resume the mission.

Error 89: Mission runtime too long

Error 89 means the Roomba was not able to complete the cleaning mission within a reasonable period of time and returned to the dock. Most Roombas will run a cleaning mission, with charge and resume occurring as needed, for up to 12 hours to clean.

If the cleaning time during a mission exceeds the Roomba’s limitations, it will return to its dock.

To solve this issue, check for obstacles that could be interfering with the Roomba’s ability to efficiently clean the space; remove and retry. Use cleaning zones to divide the space into smaller sections and run multiple cleaning missions. If the message persists, please contact iRobot Customer Care.

Error 1003: Internal communication error

Error 1003 means Roomba is experiencing an internal communication error. Press the button to restart the cleaning mission. If the problem persists, perform a robot reboot.

If the message persists after rebooting the robot, please contact iRobot Customer Care.

To solve this issue, check for obstacles that could be interfering with the Roomba’s ability to efficiently clean the space; remove and retry. Use cleaning zones to divide the space into smaller sections and run multiple cleaning missions. If the message persists, please contact iRobot Customer Care.
