My Roomba doesn't seem to have a problem with this wheel. There are no instructions for changing the wheel, which would be helpful. I have an e500 and just had to undo the 4 screws holding the bottom plate and remove it, then it took me a minute to get a good grip on the wheel and just pull it out. I think this wheel has slightly grippier rubber than my Roomba. I don't care that a real wheel is half black and half white. I would prefer it to be a solid color and I think white would look dirtier than black. The original steering wheel was all black. It snapped into place easily and my Roomba has been running on it for a few days with no issues. Please click the button if this information was helpful to you.
