You're right, I think. The bill on this is probably high. On one hand, considering the bear and other specimens may be quite old, maybe slow and meticulous is the way to go here. On the other hand, to simplify things, I don't quite get why they didn't use a regular dusting tool and a small, plain old household machine with either the bleed valve turned wide open to reduce suction or it's motor switched down low.
They could have done a test on the bear in some not obvious spot to be sure it wouldn't suffer damage.
Terminology as to vacuums has been up for grabs since the machines were invented. I was reminded by a sixth grade classmate a moon or two ago that actually they are not vacuum cleaners as they do not employ a vacuum to do their work but a partial vacuum. But, what did he know, people still call them that.
And depending upon age -- and which part of Brooklyn you're from -- they may be referred to as, the vacuum, the cleaner, the sweeper OR "the machine." Verb-wise, these references also lead to whether you cleaned, vacuumed, swept or "passed the machine."
The general use of "hoover" as a common noun and also verb can take someone from the U.S. a minute or two to process if told, "I just got a new Morphy Richards' hoover." Of course I recall we used to "simonize" our cars and "osterize" certain foods.
Nonetheless it's differences that keep life interesting.
