Start button doesn't work

Set him on the floor, after powering him off and then back on, and press the "Clean" button three times. This will reset him.

Bad PC board. Throw it away. Robot vacs are nothing more than novelties ( expensive toys ) They may do what you want them to do at first but they never last very long and other than brush replacements they are not repairable. If it is within the warranty period you can get a replacement with that.

It is possible for the charging system inside the roomba to call it quits. What I did to remedy this, since my roomba was out of warranty and I did not want to scrap it, was to buy a charging base on ebay. This charging base accepts different types of roomba batteries and even the scooba battery. The inconvenience is if you have a newer model roomba that has the battery inside, then you will need to remove the screws on the bottom plate to remove the battery. Hope this helps.

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

have you tried reset, press spot and dock together

"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 sometimes have the same problem with my Roomba 530 (named Ethel). Make sure the signal transmittor on the docking station and the signal receiver on the top of the Roomba are clean. You can use a cloth or paper towel with a SMALL amount of window cleaner to run around both of these signal devices. I also like to clean the metal contacts on the station and the corresponding contacts on the bottom of the Roomba at the same time. This won't make a difference for the docking but it just assures that the vacuum will charge efficiently. If this doesn't work, you might need to have the unit cleaned professionally unless you feel comfortable about taking the unit apart and cleaning it yourself. I did this and Ethel has worked fine ever since!
If this helps, please come back and rate my suggestion!

If you have a 400 series Roomba, try removing the battery, then holding down the power button for ten seconds, then recharging the unit before you run it again.

If you have a 500 series Roomba, don't take out the battery-- just press and hold the "spot" and "dock" buttons for about fifteen seconds. The Roomba will play a tune, and you can then charge it and try running it again later.

Call iRobot. Your charger is broken.

My Roomba has had a battery issue for some time now. I haven't used it in quite a while (months, years, I don't know for sure) because it would complain of a discharged battery after only a few minutes of cleaning. However, now when I finally tried to use it again, a new problem appeared.

Now, it charges normally, if I plug the cord directly into the Roomba. It will not mate with the home base, however, even if I place it on the contacts manually.

When I start it, all the buttons come on green. I then press a button to make it begin cleaning. The motor whirs up and runs for about 1 second, then it shuts down. About one second later, the power light and lights behind whichever button(s) I pressed (to give it a job) flash green then the system sits silent, and doesn't do anything else.
