SOURCE: Brushes are clean, but Roomba stops and says clean brushes

I decided to take it apart and see if I could fix it because even if something inside went "SPROING" and I couldn't get it back together, it wouldn't be any worse than it was already.

FIrst, remove the dust bin part and the brushes. Then, there are four screws on the bottom gray panel which have to be removed first in order to get to the gears which hold the brushes. I did not remove the little sweeper brush on the front, but I just slide it through the hole in the gray panel.

Then in order to get out the orange section which actually holds the brushes, there are four screws which must be removed. The orange section is attached to a blue section. This entire unit comes out by sliding it toward the area where the dust bin goes, being careful not to tear the light gray rubber gasket which covers the side.

Once that section is removed, there are two screws on each side. These screws hold the orange thing to the blue thing. Once the screws are removed, lift up only the side which has the white squares into which the brushes are inserted. These are actually the back side of little gears. There is a face plate on the outside of the orange part on this end. The other end contains a bunch of wires and I was careful not to disconnect any of them.

The face plate has six screws which must all be removed. Use caution when removing the face plate. Hold it up so that all of the stuff doesn't fall out. It has a bunch of gears, little brass looking fittings and grease. Take care to only remove the gears which have the squares which hold the brushes AND do it one at a time unless you like working jigsaw puzzles. I used tweezers and a pin to clean the "gunk" consisting of hair, fuzz, etc., out of the little gears.

Reverse the process to put it back together. Hazel, my little Roomba, played me a happy little song and immediately went back to work. She seems as good as new.

SOURCE: roomba keeps saying clean brushes yet are clean!

Remove the Yellow connectors on the end of the brushes and clean around the pin well. If there is too much there, the roomba thinks there is something stuck and goes into clear mode (as if there is a chord stuck).

SOURCE: no suction on Roomba 560

Larger debris is usually the responsibility of the brushes. Remove the bin and run the Roomba-- are the brushes actually turning? If not, call customer support for a new cleaning head module. If so, remove the grill from the back of the bin. Make sure that the little fan inside is clean, then reinstall the bin on the Roomba and run it. If that little fan doesn't spin, your Roomba has lost vacuum suction and you need a new bin.

SOURCE: IRobot not picking up dirt

this link fixed my prob :
http://www.robotreviews.com/chat/viewtopic.php?t=10628
and just in case the link doesn't work, basically, you have to take out the whole red brush-head assembly unit by unscrewing the 4 screw screws that hold in down in either corner; then find the side of the unit that has the gearing inputs, and unscrew all the screws until you get inside and clean out all the hair...
That should do it :)

SOURCE: roomba won't pick up debris

I had this problem until I wiped the dirt sensor, which you will find under the rollers.

Side brush will not stay on


The only way I can imagine the side brush not staying on is if the screw that holds it on is missing. Find a similar replacement screw. Did you get a package of replacement parts with your's? I did with mine, but I bought it many years ago now. While that brush is off, unwind all the thre4ad and hair that's wrapped in that section The brush will turn more easily without that all packed in there.

Brushes dont turn


If you are referring to the two main brushes underneath the Roomba (not the side-sweeper) then there are a couple possibilites:

1. The gears need to be cleaned/regreased inside the brush unit. There are several videos/guides online that will show you haw to dissassemble the gears, clean out the gunk, and reassemble. Basically there are four screws that hold the unit in; once it is removed you will see several screws on the side of the unit that contain the gears for the brushes. Dirt/dust/hair makes it's way into the gear-case and gums up the works, which seizes the motor.

2. Another possibility is that the electric motor that drives the brushes needs tp be cleaned or replaced. My Roomba had lint/hair caught up in the electric motor...in fact the dirt was separating the brushes from contacting the rotor inside the motor, which means they weren't cunducting electricity. Once I cleaned out the motor itself, the brushed worked right away! There are a couple view holes on the sides of the motor...get a flashlight and look inside...there is probably lots of junk keeping the motor from working properly.

Good luck!

I starts and tehn stops and beeps three times. I can start it aain and it will run but then it does the same thing'


Hi,

TYhe iRobot Roomba has different model designations. Here is a webpage with a list of what the beeps mean in the 400 series. I am thinking that is what you have. 3 beeps means the dirt cup is dirty, filters are dirty, or debris in collecting and it needs to be cleaned.

Here is the webpage: http://uksupport.irobot.com/app/answers/detail/a_id/1047/kw/iRobot%20Roomba%20Discovery%20SE%20Bagless%20Robotic%204200%20series%20Vacuum%20beeps%203%20times/related/1

Hope this helps. If it does, I would appreciate a vote. Thanks,

Brushes on my roomba don't seem to be spinning.


Try running your roomba with the dust bin removed to see if the brushes turn. Take the brushes out and make sure they're clean. You may need to replace the brushes if they're worn. Failing that, you can find instructions on how to take your roomba apart. Take out the brush assembly and open the screws on the side of it to expose the gears that drive the brushes. There will probably be a lot of gunk in there jamming them up. You might need to check the motor too.

My Irobot Roomba keeps saying that I need to clean Roombas brushes. I have cleaned the brushes...they are spotless. Still the Roomba will go for 2 minutes and shut itself off stating once again to clean...


Perform the troubleshooting found at the iRobot website: http://tinyurl.com/nh5c8a (I promise that really does go to the right site.) That troubleshooting will enable you to determine exactly what's causing this problem. (The Easy Way: Run the Roomba minus the dustbin and look in the back. Is the brush turning? If not, there's the problem. Give support a call at 1-877-855-8593 and they'll let you know how to replace the necessary part.)

Roomba 530


The horizontal spinning side brush is a known failure item in those units. Chances are the side brush motor has gone bad. Check first to make sure that the motor isn't just bound up with hair or something.
Fortunately, it's easy to replace and relatively inexpensive.. See this video link on iRobot's site: http://www.irobot.com/hrd_right_rail/roomba_rr/roomba_fam/RoombaFam_rr_howitworks.html

Click on the bottom link in that video to see how to remove the bottom plate and remove that side brush motor with just 2-3 screws. New motors are available from iRobot for $15 or from places like www.RoboticVacParts.com for ~ $10 links here:
