Question about iRobot Roomba 4210 Bagless Robotic Vacuum

2 Answers

Roomba My Scheduler started making a "grinding" noise every now and then until one day it just started grinding and then stopped (I could restart the unit, however it repeated the grinding and stopping). I have checked the wheels and all of the gears appear to be in good order. I have a hunch the brush motor may be stripped. Any opinions? Thanks: RAnderson

Re: Roomba


Further investigation (running diagnostics mode) revealed the impeller (in the dust bin) was out of whack. I got another dust bin from EBAY and replaced the impeller and motor. Unit works fine.

Re: Roomba

Mine did the same thing. I'm going to send it back for a warranty repair.

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.

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

Roomba 530 makes a thumping noise every secondand stops with a message to clean he brushes. I have cleaned the brushes and filter but to no availe the thumping continues.

You also need to pull off the yellow bearings from the end of the brushes (one on the brush one and one on the rubber one) and remove hair from the axle there.

My roomba 400 series keeps stopping on its own

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.

Roomba Schedular

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.

Roomba Red Problem

Mine did a similar thing. I kept trying to use it anyway, when it made a violent jerk (I thought it had broken something) and it started to work again.

Have you tried pressing both buttons at the same time to make it go straight ahead? It might work.
