Reply to comment by xhephaestusx in can you run an ethernet cable through an empty conduit in your house on your own? by VanillianArt

Have you ever heard the term "thin air"? When you pull on air it stretches. The more air between you and what you want to pull the more space air has to stretch, and the more air there is to stretch. This overworks your vacuum. The longer the pipe, the less efficient the vacuum is. The air has friction against the surface area of the pipe and adds drag which stretches the air thin.

This makes some sense, and plays into the pressure differential example the other commenters gave, thanks for taking the time!
