Question about Vacuums

Roomba only goes backwards for a brief time then shuts off and beeps nine times. I've taken it apart and used can air to clean the 4 sensors. Any other suggestions?

Have you popped out the black and white castor wheel and cleaned that out? It is a part that should be replaced from time to time. The vac uses an optical sensor to see if the wheel is moving. If it isn't, it tries to back up and see if something is stuck in the wheel. Pop the wheel out, clean it and the shaft it sits on and put it back in. Wipe out the cavity before you reinstall it.

You'll need to replace the IR sensor component. You can order a kit from http://www.eesolutions.ca. They also have the option for a kit if you don't have a soldering iron, so that might be something you might be interested in.

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

I starts and tehn stops and beeps three times. I can start it aain and it will run but then it does the same thing'


Hi,

TYhe iRobot Roomba has different model designations. Here is a webpage with a list of what the beeps mean in the 400 series. I am thinking that is what you have. 3 beeps means the dirt cup is dirty, filters are dirty, or debris in collecting and it needs to be cleaned.

Here is the webpage: http://uksupport.irobot.com/app/answers/detail/a_id/1047/kw/iRobot%20Roomba%20Discovery%20SE%20Bagless%20Robotic%204200%20series%20Vacuum%20beeps%203%20times/related/1

Hope this helps. If it does, I would appreciate a vote. Thanks,

Handie Andie

Roomba 530 Nine beep error. I took off the front bumper and cleaned it throughly. Looks like itmay have to do with poor infrared emitters as they dim over time with getting older.


Nine beeps mean optical sensor unit/bumper actuator failure. Here's a link for you. Hope it helps....http://www.protechrobotics.com/proddetail.php?prod=245435775

535 series - just put in new battery - does not work - just spins around in circles and tries to back up - then beeps nine times (bumper?) Won't dock.


Hey

Please look for other same problem posted here ;-)

You are probably facing a bumper sensor issue.
Try to clean the bumper first and if this goes on, either call iRobot service, or
take a look at this page for the step by step 9 beep fix.

Backward spinning roomba


If you are lucky then one of the 4 sensors under the bumper has dust lint buildup. Blow out these areas and give your unit a good cleaning. If it still continues to do this then the bumper bar sensor should be replaced

Backs up spins in circles, then red light flashes and beeps


Sounds like either the battery is bad or not being charged properly with subsequent loss of programming.

Our roomba vacuums, then beeps 5 times and shuts off.


Your cliff sensors aren't working properly. Tap the bumper five or six times to knock out anything caught behind it, then blow out under the bumper with some compressed air, really thoroughly. If that doesn't do it, call customer support at 877-855-8593.
