IRobot Roomba 620 wheel
I have a iRobot Roomba 620. I turned it on one day and it wheeled around in a big circle. After about 30 sec. it says, “error 10, spin wheels etc”. I did that, nothing. I order brand new wheels components, put them in, reset by holding down the “spot & dock” buttons.
I took the new wheels out again and I noticed both spun the same until I put them in. The left on is a bit stiffer. You can hear it too when the motor turns. The free-er one has a higher motor sound.
This is where I am stumped. Circuit board?
