Charles, Thanks for the Youtube search tip. Haven't done that one yet. The one to which I linked was just found doing an "Electrolux vacuum" search.
Tom, I bet you're right that the boy you mentioned--and maybe even a friend or two--will be a vac salesman someday.
Until I arrived at Vacuumland I'd never thought much about youth (not to mention young children) being interested in air and room cleaners--probably because I wasn't. However, it stands to reason that every item that exists--either designed by God or manufactured by persons--can lend itself to curiosity, and/or fascination, and/or appreciation, and/or fondness. It's fun to see that develop.
