Roombas are fantastic but they are often prone to suicidal tendencies. Seriously, they'll slurp up clothes and cords like there's no tomorrow. No matter how hard you try to pick things up and keep the Roomba's brushes clean, a brush assembly failure is inevitable. Luckily, this is the most common part to break on a Roomba and it's inexpensive and easy to replace.

I'm going to perform this repair on a 500 Series Roomba (iRobot 560 to be exact), but the brush assembly (AKA cleaning head module, Part No. 21917) and procedure for changing it are identical across all 500, 600, and 700 series Roombas! So unless you have a really old Roomba, you're in luck.

So for about fifty bucks, your robot buddy can terrorize the family cat once again!
