iRobot Roomba S9 Plus: Roomba S9 Plus Making Error 2 With Clean Roller Brushes

Sat, 29 Nov 2025 12:19:02 -0700

Recently, I have been noticing that my Roomba S9 Plus makes an intermittent whining noise. The Roomba frequently stops and mentions Error 2 for stuck roller brushes, even though the brushes appear clean and spin freely by hand. If anyone has ideas to help fix the issue, I would greatly appreciate it.

Thanks in advance.

Just an update,

I found the issue. Seems like the gearbox of the cleaning head that spins the rollers is most likely starting to fail. It is not easy to find a good cleaning head for the S9 Plus. But I did find the roller brush motor assembly itself on some platforms like eBay. However, I cannot find any repair guides for installing this. So what now?

iRobot Roomba S9 Plus: Why does my Roomba beeping and 12 white circles followed by red circle

Sun, 06 Aug 2023 12:59:47 -0700

I was gone for a couple days and my Roomba got stuck in an area it doesn't normally go to. Since then I can not get it to work. The lid circles white 12 times then has a lower and higher beep. Then lid then goes red for about 4 seconds. The cycle then repeats until I remove the battery. I have removed the left and right wheels and even the front bumper and still continues with the same pattern. At one point I got an Error 24 message and no reporting since. Any suggestions as to what is the solution or other things to try resolve this?

iRobot Roomba S9 Plus: constant "Empty the bin" error

Tue, 18 Feb 2025 13:51:10 -0700

Whenever it is scheduled to run or I press clean.. I keep getting a "empty the bin" error. I have replaced the filter, cleaned the dust bin, cleaned the rollers, wiped down everything & rebooted but this error won't go away. I read someplace that the "vacuum fan" may need to be cleaned..? I have no idea how to do that & I can't find any videos or directions.

iRobot Roomba S9 Plus: My iRobot Roomba S9 Plus keeps getting stuck

Wed, 16 Feb 2022 10:30:06 -0700

My S9 keeps getting stuck on items that it used to have no problem with. Like an area rug or even going back up into the docking station. It is not elevating to go over these surfaces. It also is making more noise than it use to when vacuuming.

iRobot Roomba S9 Plus: Why is my Roomba spinning in place?

Sat, 19 Dec 2020 12:45:57 -0700

It’s the first time I’m using my Roomba s9 and it makes a weird squeaky noise on the left side, it only moves forward about 3 inches, spins in the same place and then it stops. Also on the other side where there’s a side brush it won’t turn but I don’t know if that’s because it doesn’t really move forward that much or is there a problem there too? The red light comes on but it doesn’t say any error messages or code. What should I do?
