    My Roomba used to shut down and give me the "Please Inspect and Clean Roomba's cliff sensors" error. No matter how much I cleaned them, it would work for a few minutes than shut down with the same error. I finall solved that problem by taping some white printer paper over all the cliff sensors! (I have a single story house, so they aren't needed anyway.)
    Now it shuts down with the "Please inspect and clean Roomba's brushes" every few minutes. I have completely disassembled the damned thing, cleaned the brushes, gears, wheels, and everything else. It worked for a couple days, then went back to the same error. Is there a way I can easily defeat the brush cleaning shutdown?


  • ohb0b May 18, 2009

    Nope, that's NOT it. When I said I completely disassembled the damned thing, that's what I did.... all the way down to the gear box. I even used the straight pin, tweezers, sharp knife, and it still shuts down on "Please inspect and clean brushes" error.
    My guess is there is a torque sensor somewhere, when the motor has to develop extra torque to turn the brushes because of built up dirt, it sends the signal.
    I was looking for a way to either bypass it, like I did with the cliff sensors, or at least turn the setpoint up to avoid nuisance shutdowns.

The brushes are clean on the outside, but probably not inside of the little yellow contact on the end. Also the junk that collects on the brushes finds its way into the gear box. Mine kept shutting down w/ the "Please remove and clean Roomba's brushes" message. I finally gave up and took it apart. There was a surprising amount of junk in the gear box. After I got it apart, I cleaned it out and I even used a straight pin and a pair of tweezers to get all of the gunk out. Now it runs like new. I'm no mechanic, but I used to help my daddy fix things around the house. I posted my solution to the problem and it has worked for a couple of other people too.

Red triangle and roomba stopped


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.

Roomba stutters on one wheel causing it to quit


Try setting the Roomba on the floor, powering it up, pressing down hard on the front, just above the front wheel, and hitting "clean" or "spot." My Roomba had the same problem, and this seems to do the trick for it. I think it has something to do with the Roomba thinking the front wheel is extended (which would indicate a cliff) even though it's really not.

If this doesn't work, you might try pressing down over whichever wheel doesn't turn when you turn the Roomba on.

My Roomba is moving real slow and turns very often then turns itself off after a few minutes. I have a new battery.


There's a chart in the back of your manual that lists the beep codes. If it says "contact customer support" under the "troubleshooting" section, call 1-877-855-8593. We'll be able to diagnose the problem based on the beep code and hopefully get your Roomba up and running again!

(Can't find your manual? Visit http://homesupport.irobot.com and search for "beeps" after selecting the correct Roomba category.)

Backs up spins in circles, then red light flashes and beeps


Sounds like either the battery is bad or not being charged properly with subsequent loss of programming.

Reset the Roomba by removing it from the charger, then holding "spot" and "dock" for about twelve seconds. When you let go, the unit will play an ascending series of notes. Then recharge it overnight. If the run time is still short, give Customer Support a call-- be sure to have the Roomba with you when you do.

Roomba cuts off after a minute or so.


If you have a 400 series Roomba, try removing the battery, then holding down the power button for ten seconds, then recharging the unit before you run it again.

If you have a 500 series Roomba, don't take out the battery-- just press and hold the "spot" and "dock" buttons for about fifteen seconds. The Roomba will play a tune, and you can then charge it and try running it again later.

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

Roomba does not do anything


My Roomba has had a battery issue for some time now. I haven't used it in quite a while (months, years, I don't know for sure) because it would complain of a discharged battery after only a few minutes of cleaning. However, now when I finally tried to use it again, a new problem appeared.

Now, it charges normally, if I plug the cord directly into the Roomba. It will not mate with the home base, however, even if I place it on the contacts manually.

When I start it, all the buttons come on green. I then press a button to make it begin cleaning. The motor whirs up and runs for about 1 second, then it shuts down. About one second later, the power light and lights behind whichever button(s) I pressed (to give it a job) flash green then the system sits silent, and doesn't do anything else.

Help


I had the same kind of problem with my model 400 today...after starting it and having it go in a circle for 30 seconds or so it would finally run into something and then back up a few inches, turn, then go forward a few inches, then back up a few inches, turn, then go forward a few inches, etc., etc.. I tried cleaning off the four pairs of sensors under the bumper and blowing out various things underneath (by mouth since I didn't have any canned compressed air). It didn't really help. It then occurred to me that I had a leaf blower! I put the Roomba upside down on the grass, put the leaf blower on high, and blew at it from all directions and up close. More dust came out than I thought would. It has been running normally now for the last 45 minutes.
