My response was not to prove/disprove a maker's first and unique use of
a particular technology/feature and/or application thereof. I named a few that
came to mind and have since thought of others. The vacuum industry
is over 100 years old. Most of the vacuum features and technology over the
years have been used, reused, copied, improved, expanded, embellished
and fine tuned. That's what happens over time. It's called progress.
The first map of the world was based on the best knowledge and technology
gathered by the persons who explored and made maps at the time. We don't hold
onto them forever. Over time the knowledge increases, the technology improves and
the maps get better and are improved. We don't keep and use the same maps for tradition's sake.
We make and use better maps based on more definitive information and experience of the persons
who came after. Vacuums are the same. They get better over time in form and function. We would
be foolish to think that a decades old EUREKA Whirlwind bagless is the best for today's environment
and better than what has come after.
