Got all the leaves out.
Used a car vac and alternated between using it to blow air and vacuum - having a slim-adapter at the end to increase the air velocity. Took about 30min of going back and forth. I think that if I had simply used only vacuum, I would not have gotten anywhere near as much out!
The onboard fire extinguisher is a good idea too. I think I may get one.
