Question about iRobot Roomba 4210 Bagless Robotic Vacuum

Roomba 4200 Scheduler

The battery life on our beloved Roomba has really tailed off in the last 2 months - we've owned it about a year, run it 4 times a week, and now have only 30 minutes of run-time before it goes "dead red" (initally, it ran for 1 hour and 25 minutes). Apart from buying a new battery, any suggestions?

The best for the battery if (NiMH). Discharge completly, than charge full (charge more even the charger indicates full charge)

Clean every part, maybe a hair slow down the wheels and thats why need more power.

Here some tip from the web:

With proper care, one iRobot Roomba battery can last for hundreds of cleaning cycles before you need to replace it. Here are some things you can do to extend Roomba's battery life and keep Roomba cleaning at peak performance:

Use your Roomba frequently. Your Roomba is powered by a rechargeable nickel metal hydride (NiMH) battery, which lasts the longest when you use it regularly.

Keep the brushes clean. If the brushes and brush axles get clogged with hair and other debris, your Roomba will strain to spin them, using more battery power than normal. In extreme cases, the battery can even be damaged. See How to remove and clean Roomba's brushes

Keep your Roomba plugged in when not in use. If you have a Home Base®, keep your Roomba docked in the Home Base and plugged into the charging brick. If you don’t have a Home Base, keep your Roomba plugged into the APS Fast Charger.

Make sure you are charging your Roomba correctly. When your Roomba is plugged in correctly, the solid green light should be illuminated on the charger or on the Home Base.

Plug your Roomba in as soon as possible after using Max Mode. Leaving your Roomba unplugged for more than 24 hours can damage the battery.

Place your Roomba and the Home Base on a smooth, hard surface when yourRoomba is plugged in. Make sure your Roomba and the Home Base have plenty of space for ventilation. Do not charge your Roomba on a carpet or rug.

Charge and store your Roomba in a cool, dry place. Keep your Roomba out of direct sunlight and away from sources of heat such as windows, radiators, heating vents, and large appliances.

Remove the battery when not using your Roomba for a long period of time. If you will not be using your Roomba for more than a few weeks, fully charge the battery, remove it, and store it in a cool, dry place. When you want to use your Roomba again, insert the battery and fully charge it. Leaving your Roomba plugged in for weeks when it is not being used can damage the battery.

You can purchase a second battery or replacement online at the iRobot Store.

My roomba wakes up in the middle of the night and makes wired noises

Is this a Roomba with, 1. low power, 2. one that had low power, but is now charged up and ready to go or 3. did your power go off briefly the night and when it came back on Roomba got a power surge and "responded". You might want to try unplugging Roomba when not charging or being used. I did this but it seemed to affect how long by Roomba could run later between battery recharges.

New Roomba Battery Not Holding Charge - charged once then died

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.

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:


YELLOW = MISSION ABANDONED (Check robot's brushes, etc.)


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 noticed my run time was getting shorter and shorter, within the first 6 months. I checked my charger and base with a V.O.M. okay. About 4.4 volts on the base about 14 volts on the direct line. I bought...

To extend Roomba's battery life and keep Roomba cleaning at peak performance: • Always keep Roomba plugged in when not in use. • Recharge Roomba as soon as possible. Waiting several days to recharge Roomba can damage the battery. • For storage off the charger, 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.
16-Hour Refresh Charge If Roomba has been left off the charger for an extended period, Roomba will initiate a special 16-hour charge cycle. This extensive charge refreshes Roomba's battery and extends the battery life. While charging, Roomba's "Clean" button will pulse quickly. Note: For best results, do not interrupt this Refresh Charge.

Roomba would run for 2 seconds and then stop it Plays 4-note song as Power button blinks RED. if I remove the battery and then try again, it repeats the same.

Probably, the battery has little service life left and should be replaced. You might let the machine run until there is no light showing at all, recharge fully, then try using it again. If you know someone that has a similar unit, try swapping batteries to check. Good luck!

Battery charge

Dave you are correct. You should never over-charge anything like a Roomba, Cel Phone, etc. That will kill a bettery very quickly.

Let it charge for a full 24, or even 48 hours, regardless of the green light. If it still dies you probably need a new battery.. or worse.
