Bought a ash vac off of Amazon. Used it for the first time today. I love it! Vacumed out all of my fire boxes. 3 of them and the vac still had room for more ash. Vacumed out the Santa Maria, the vertical smoker and my horizontal smoker so there was quite a bit of ash. Much better than using a ash shovel and a bucket. You can even pick up hot ash with it as the hose is steel lined. Even comes with a few accessories. What's nice is it gets all the ash out of the corners and sides so nothing is left to absorb moisture. Highly recommend one if you are a stick burner!
