This video is easy to follow. The only equipment required is a phillips head screwdriver. I spent about 30 minutes cleaning mine, and the first 10 minutes were just trying to understand how it got so gross in the first place.  The difference in suction is noticeable, though, so this was definitely worth it for me. Good luck!
