Have you tried to check the rollers carefully right after getting the error 2? For some reason Roomba is thinking that something is stuck in the robot vacuum rollers as they creating the resistance. If you have it for a while it might be that the inside gears are getting resistance from dirt. You can see in this video how to repair it.

Argh this is an annoying error. I kept facing it as well. It’s super important to check the rollers - that is the first thing I would suggest to do. Usually, that is the problem. The rollers are probably just stuck or dirty. Otherwise, google troubleshooting for roomba. There are many guides available. I saw this one. That’s what I did.

I have completely disassembled mt Roomba 500. Cleaned brushes meticulously, disassembled the drive train. Cleaned gears and axles. Still get Error 2! I infer that the resistance is upstream of brushes and gears. Perhaps the motor shaft itself. That will be a very tough repair for me

So I received this error. I removed and cleaned the rollers as well as the entire cage, this did not fix the issue. I replaced the rollers with new ones as the existing ones were not in the greatest of condition. Replacing the rollers did fix the issue.

Cleaning the front wheel fixed the issue for me.

Something is impeding the drive train. Usually, it is the brush loaded with stuff it picked up. If the brush is clean, it obviously is not a clogged brush. The next step requires you to disassemble Roomba. Take brush, roller, and brush keeper. Easy part. Remove the bottom plate. It is held on with screws. Don’t lose them. You also mustunscrew and remove the circular sweeper thing. The bottom should come off. Now you must remove the entire piece that holds the brushes. Careful because the motor wires are attached. There is enough slack that you need not - and should not- unwire the motor. The piece that holds the brushes comes out. But not easily. There is a spring plastic catch right and left. You must depress both simultaneously (takes two hands), grip the brush holder piece (third hand) and hold the body of roomba attune rear (fourth hand), and pull the assembly out (fifth hand). People with five hands find this easy. It is almost impossible with only two hands. The entire green thing comes out. Including the gear box on one side. Carefully disassemble the gear box. Five or six tiny screws to keep track of. Lift off the cover from the gear box. There are several Teflon gears. They just slide off. Remember which one came from where. Likely, each gear will have accumulated sludge, and the axles will have strangled themselves I loose threads. Clear everything.. put the gears black in. DO NOT CLOSE UP YET! Spray everything in the gear box with WD40! Very important Now close the gear box and reassemble everything. The two front spring clips on the front of the brush housing will fight you. There should no longer be error 2. The brushes weren’t clogged. The gears were gummed up. Stuff migrates into the gear box over time. You have to execute this goat rope every year or two. There is not much to the Roomb@. All that’s left is the battery, which is easy to replace, and the motor, which is easier to deal with than the gear box was. Most of the functionality is in the electronics.

Almost none of these instructions come with Roomba or are in the manufacturer’s website. Phone help is clueless. You do not need to trash the Roomba or pay for repairs. Good luck. Remember that persistent Error two does not mean that the brushes need attention. It means that the drive train is clogged!

Does the front wheel spin freely?

If not, clean the front wheel

This fixed the problem for me :)

I posted this a while back. The brushes are not the problem. The gears that drive the brushes are the problem. The gear train is inside a green housing on the left side facing Roomba front. Removing it is a pain, but it requires no special tools or skill. Removing the brush holder is a trial, but it is just spring loaded right and left. The problem is that you must depress the right clip with your right and the left clip with your left hand while pulling out the housing with your middle hand. At least three hands required. Then extract screws and pull off the side of the housing. Gears slip on and off easily. You will find an amazing amount of gunk, threads wound around axles, etc. You get Error 2 whenever the motor experiences excessive resistance somewhere in the drive train, not just the brushes! Before you put the gear cover back on, spray the inside with WD40. That should fix things for a long time. But eventually it will happen again.

We had same problem. Make sure the little”string” between the pully on end of motor and middle of blue chassis. If it missing that’s the problem. Roomba website shows where it is We used a piece of nylon thread/ thin fishing line She’s working great.
