Re: roomba just runs in small circles

It's little brain is having a seizure. Really! It's a programming fault. If you look on the machine, usually the bottom, you'll find a 1-800 number you can call and they have a solution for it. It's fairly common for this to happen and it cannot be solved with any mechanical solution.

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.

My roomba makes a banging noise and goes around in circles


a roomba going round in circles is so common that it is known as the "circle dance" problem and there are videos on you tube showing you how to fix it, step by step. search for "roomba circle dance" on youtube.

i would not normally redirect you to another site, but these videos are clearer than any written instructions i can give here. watch a few of the videos as there are some slight differences to the basic problem and follow th eone that matches your symptons most closely.

hope this helps

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...

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

Turns in circles, acts like it hits a virtual wall then stops

Reboot is probably not your solution. Your Roomba will react to invisible signals or 'interference' from other electrical appliances as well as the invisible wall boxes. You can clearly see how this happens when a Roomba gets near your computer or other device that is on. Also, the Roomba will go in circles when the dirt chamber is full or it thinks it's full. Try a thorough clean of all major parts including the brushes. Sometimes this activity will occur when the brushes get snarled on thread or carpet fibers.

Red sensor

If your Roomba's red "check robot" light comes on, the Roomba should also give a hi-lo warning tone, then a number of beeps. Check the number of beeps with the chart toward the end of your manual-- it should tell you what to do.

Roomba can't make a turn and stops working

make sure the wheels are not clogged with something like hair or carpet strands if that don't work it sounds like your right turn sensor might be the roomba people or go to and look for your model and find troubleshooting

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 Stops

I just fixed mine by cleaning the shaft that the spinning brushes is on. I used an eyeglass screw driver to tke out the screw. it is running great now. I didn't realize my brushes werent spinning at the time of my post. Cleaning this part seemed to have fixed the problem.

My roomba starts going backwards

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.
