Question about Roomba 770 Robotic Vacuum
Roomba stopped and red triangle lit up
Posted by Anonymous on
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!!!

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.
