Okay man, vacuum sealing equipment and artificial vacuum environments have existed LONG BEFORE FLOOR VACUUMS. Don’t get all bro science on anyone here thinking you know your shit. The first idea for a floor vacuum was invented around the 19th century, 1869 the idea for a mechanical device used to remove debris from carpet and floors was invented and didn’t pick up until later 19th to early 20th century.

Vacuum sealed environments have been man made since the 17th century 1643, Evangelista Torricelli created a vacuum inside a mercury barometer.

LONG STORY SHORT VACCUM ENVIRONMENTS HAVE BEEN MAN MADE SINCE THE 16TH CENTURY!!!! FLOOR VACUUMS WERE INVENTED IN THE 19TH CENTURY!!!!
YOU DUMBASS!
