Status light is red, why? I have a Roomba Discovery.

"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 Charging circuit on the main board is dead. Either replace the main board or repair it if you have the skills and equipment.

Take off the grill on the back of the bin. The round vacuum impeller is behind it. Make sure that's clean and free of debris. Run the Roomba with that little grill still off the bin-- is the impeller turning? If yes, you may have fixed it. If not, your Roomba needs a new vacuum bin.

cor2an,
That sounds like a classic battery failure in the Roomba discovery series. There are sensors inside the battery pack that go bad too. Either way...it's not very practical to repair the battery....the best shot you have would be to order a replacement battery. You just pop the old one out and then put the new one in.

buy a new battery ,the old one isn't holding a charge

When the status light comes on, the Roomba is going to sing "uh-oh," and then beep a number of times. Count the beeps. They're a code that tells you what's wrong with the Roomba. You can check iRobot's website for a chart of beep codes. Search "What is Roomba saying to me?" on the troubleshooting page.

your battery isn't holding a charge ,buy a new battery

Cleaned the shaft that the spinning brushes are connected to. Used an eyeglass screwdriver to remove the brush.

My status light came on, the vac beeped twice and stopped. I noticed my brushes weren't spinning. I took an eyeglass screwdriver and took off the center screw that holds on the brushes. I cleaned the shaft that the brushes spin on. replaced brushes and it works great! I just did this now and it is still running. my status light problem is fixed my roomba is 4 years old and I am on my 2nd battery. Seems to have fixed the problem. FYI it was wrapped with hair, dirt and it was greasy.
