If you get a red triangle with the two tone beep, and no voice prompt, roomba 770 runs for a few minutes or just immediately goes to red triangle...if you have thoroughly cleaned moving parts and find no obstructions, you may have the problem I had that stumped me for a week. Remove the trash bin, with roomba upside down, and there are 4 silver contacts that connect to two metal tabs on the trash bin. Over time the contacts lose some of their contact pressure. Use needle nose pliers to slightly rebend them so they make good contact to the trash bin contacts. These contacts feed the vacuum motor inside the trash bin. That fixed mine.

SOURCE: 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.

SOURCE: roomba 4108 does not charge

Try resetting your Roomba by removing the battery, unplug the charging connector, hold down the Power button for 30 seconds. This will reset the charging system, replace your battery, connect your charger and see what happens. By the way do you also have a homebase ? If so try that too

SOURCE: problems with roomba 530

before taking apart your Roomba read this!!! First to see if it is a defect or really the brushes, take the brusehs out and run roomba with out them. If you still hear the clicking/ thumping then try taking it apart or call roomba. But if the clicking/ thumping goes away when the brushes are out you're in luck! Take the brushes. The brushes have little yellow nubs... those come out. pull them out, and you will see a lot of hair waiting for you. clean all of the hair out ( tweezers are wonderful for this). Once they are cleaned out put the yellow nubs back on. Put your brushes back in and you're Roomba will be back to business in no time!!!

SOURCE: Roomba stops and beeps three times.

After reading Solution #4 and not feeling much of any air come out of the vent, I used a flat head screwdriver to remove the grill at the back of the debris bin. I then spun the vacuum impeller around, shaking out any debris that was stuck (a little wad that had plugged it came out). I then replaced the grill and put the dirt bin back on, and my Roomba worked!

SOURCE: no suction

Roomba does much of its cleaning by the brush and roller on the bottom, but an important part is the little fan at the back of the debris bin which provides 100% of the 'suction.'
First, take off the vent cover on the back of the debris compartment and start Roomba on a mission. You will see the little turbine spin (if it's working) and probably a little dust cloud will come out.
It may not be working at best efficiency, however, because dirt gets sucked into the housing and blocks much of the air flow. Now that you know what the fan/turbine looks like (it's quite small, only the size of two stacked silver dollars), peer down into the larger opening of the debris bin and view the turbine from the other side. Chances are there's some crud stuck down there which is impeding air flow. (There's a hollow part of the turbine where the air is sucked into before being expelled out the back, that's probably filled with pet hair/dust/etc.) Clean that out using a long knife, chopsticks, or anything else that can reach down in there. Bang the dust bin down (lightly) to dislodge any more hair that's up there and continue cleaning until it's all gone.
I've had 3 Roomba's and they all get hair stuck up there. I only have to do this once a year or so (multi-cat and dog household here!) but it makes all the difference in the world.

Amber flashing light while on home base. New, pulled tab, placed on dock. First time said charge err1, took out battery and replaced. Now just flashes amber. Is this correct?


Your manuals are here. Flashing lights must be covered. A quick look at the site says flashing red is bin full. In fact, I found it. Flashing Amber is CHARGING.

Room a 620 keeps stopping


It could be clogged with hair (when was the last time you cleaned it out?), it could be the battery isn't holding a charge any longer. It could be getting caught on something . How long is it running before stopping? I found I used to get about a two hour run from my Roomba, before the red light flashed. Then I started to unplug the charger and Roomba when it had a full charge and it wasn't needed. I noticed that after this the Roomba didn't run as long, maybe one hour, before needing a charge again. I leave it plugged in all the time now.

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


Hi.

If the red light is solid, that means that the Roomba is near to full discharge. If the light is flashing red, then the Roomba is completely out of charge.

If the Roomba is fully charged, then there may be a fault.

Here full list of light codes:

Pulsing Amber - Charging
Green - Fully Charged
Amber - Partially Discharged
Red - Almost Fully Discharged
Flashing Red - Fully Discharged"

Roomba red #4100 needs repair does the circle


sounds like you have two different issues here. (Possibly one common)
Clean out the cliff sensors. Under the bumper. blow it out clean. This might stop the reverse circling. The battery is either bad, or the charging circuit is bad. if battery is know good then the problem is the main board needs to be replaced. a bad battery will kill a main boards charging circuit by over working it with shorted batteries

My roomba 530 runs in a circle and does not move forward. After 2 minutes it stops with 11 beeps and a flashing red light to the left of the power button. It has no clicking noise. Does anyone know what is...


Hey'
This means Roomba is not registering obstacles. Roomba may be stuck in one place.
Roomba may be in extremely large room, try setting up virtual walls to create smaller area.
If Roomba is not in a large room, tap Roomba's bumper to confirm it is properly working.


Hope this helps

Roomba red 4100 cleans in small circle stops starts agains cleans small circle stops then status light comes on and clean button blinks.


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.

Roomba brushes won't spin


I had this problem with my Roomba Discovery. I ran across your question while searching for an answer. My main symptoms were, Roomba hesitated a lot, and the dust bin did not fill. I had plenty of hair wrapped around the brushes and against the filter.
I just finished taking my Roomba apart. I found the motor drive shaft had a LOT of hair wrapped around it and it had climkbed into my gearbox. I took that apart and cleaned all the hair out of the gearbox. My Roomba is back to normal now, filling the dust bin.
