This was a very good tool.  We had quite a build up of lint in our dryer and its associated vents.  The tool was so strong, we didn't have to use the drill attachment.  Rather, we used just the tool and it was very successful.  Our dryer works as good as it did the day it was delivered.  We're now on a schedule to use this tool quarterly.
