Evolution of Vacuum Technology
Vacuum technology has evolved significantly over the past 100 years. Initially, vacuums were as large as minivans and costly. However, inventors redesigned them into various shapes and sizes, including canister vacuums and even those resembling R2D2 from Star Wars. Tom Gasco, a vacuum enthusiast, runs a museum showcasing his collection of vacuums, some dating back to 1879. These advancements reflect the continuous transformation and innovation in vacuum technology.
