During a recent project a volunteer asked me why I was blowing the dirt and
dust away instead of using a vacuum cleaner to suck it up and get it out of
the way for good.  I replied "because I am too lazy" but I'm sure he
thought it was because I finally found a use for all that hot air (hold the
comments to yourself, please, this is a nice list).

I know of several projects were vacuum cleaners have been used
suckcessfully in cleaning floors, brickwork, burned timbers, etc., but I
have never tried it myself.  I bet it works wonders in certain situations,
and helps with photography, but I can think of a thousand situations that
would be just asking for trouble.

Have ye fellow listers experimented with vacuum cleaners (in archaeology, I
mean!  keep it CLEAN).
