Brush not working

My roomba functions normal but it no longer picks up anything.

The brush's do not move...

When I try and manually move them they roll back and forth but not all the way around. (Not sure if this is normal....)

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

Took Roomba apart to clean and now the pick up brushes start and stop during cleaning. The vaccum is clean but will not constantly spin. Runs great but pick up brushes start and stop. Is there a number...

You can go to . This is the roomba website. You should be able to find replacement parts, customer support, videos or the Roomba product, and more.
When you cleaned your Roomba, did you also clean the wheel wells and outer most edges of the brush brush cartridges? There can be lint, threads, and at my house, cat hair, wrapped around the outermost edges of the brush cartridges.
I hope my suggestions help. If so, please contact Fixya and rate my solution.
Thanks and Good Luck!

I have cleaned & cleaned this thing! It runs for about 2 mins & stops, says "Clean Brushes"! and now it's very noticeable it's not picking up well... but is picking up a bit. I take the dust bin...

Ok, this is a "Brush Height Adjustment" issue. It will probably work great on a hard surface but on carpet the brushes bog. If you've taken the unit apart it again. When you do, you'll see a String which allows the brushes to "Float" on different surface heights. Loosen the screw a little and pull a bit more string through. Re Tighten the screw and put it together enough for a test run. Now reset the roomba.To reset the Roomba, power the Roomba on, and press the Spot, and Dock buttons together for at least 8 seconds. Until it plays a tune. The clock, and any schedule is erased at this time. Try running the Roomba with the dust bin removed to see the brushes spin easier.

Second method, is taking off the bottom cover, and removing the battery. While it's removed, and not plugged into the charger, press the clean button for at least 20 seconds. This will erase the memory. Replace battery, and cover. Run the Roomba to see if the brushes start to spin. You can also remove the brush housing by removing the 4 screws and reseating it, to see if it was a bad connection, since you have the bottom cover off.

Roomba keeps saying "Clean Brushes"!!

Have you made sure the brushes aren't clogged with thread and hair, and that the brush bearings are still good?

1) remove the brush guard.
2) remove the brushes
3) remove any hair or debris using the cleaning tool

4) replace the Roombas brush bearings


5) replace brushed and brush guards

If this doesn't work then, try the following:
  1. Power off the Roomba.
  2. Remove the dirt bin.
  3. Place the robot upside down on a flat, padded surface.
  4. Check for any dust or dirt obstructing the Cliff Sensors (with Roomba upside down, the sensors are located in the four rectangular areas just inside the edge of the front bumper).
  5. Next, press the front bumper in to make sure it springs back.
  6. Make sure both yellow brush caps are installed correctly
  7. Make sure the main brush and the flapper brush each have a yellow bearing installed correctly.

My roomba 550 keeps making a clicking noise and it says to clean the brushes, even after I do it

Hello, this type of Clicking sound is most likely a loose alignment within the brush axles. There is a particular way the brushes have to go, each in an individual position. Try to tinker around with the position(s), :) lol... this should solve the Clicking caused by miss ~ alignment. :)

New Roomba 560 beep twice, ask to clean brushes, but no dirt

your roomba is thinking that you need to clean the brushes. if too much load it put on your brush motor--the unit will think that something is wrapped around the brush and slowing down the motor. if you have cleaned your brush and are sure that is not the problem; you need to look for anything else that could be slowing down the brush/motor. If this is inconclusive you need to put your roomba into diagnostic mode by following the procedures in the link below

IRobot not picking up dirt

try to replace the filter, that should work.

Roomba Discovery

did you replace the filter? when you remove the dust bin there is a small filter that needs to be cleaned, or replaced. You can buy a maintenance kit that replaces the brushes and filters as well, its good to replace them all regularly

Roomba turning off after 30 sec.

I was having the same problem. Roomba would run for 30 seconds and then stop. I tried everything -- then I took the small rubber brush out and removed the small nut at the end. It was packed with dust to the point that it could not turn easily. I cleaned it out and now it is working like a champ. I think the automatic shut down was just a sign that there was too much strain to turn the brushes.
