Roomba - Cleaning the front wheel
Standard disclaimers apply -- you break your toy, it is your problem!
Front wheel of the Roomba, with the pin in the center of the wheel.
Pin pushed part way out... NOTE: Support the legs as you push the pin out. They are plastic after all!
Don't push the pin all the way out--just far enough to remove the wheel.
To reassemble, line up the wheel, and push the pin back through.
