Let's Fix - Replace iRobot Roomba Cleaning Head

Now matter how diligent you are maintaining an iRobot Roomba, the cleaning head eventually wears out and throws erroneous "clean bush head" errors. At a point, even repacking the gears isn't enough. Don't fret. It's a remarkably simple fix. All you need is a Phillips bit 2, 0, and the new unit (~50USD from iRobot).
