We’ve heard plenty of people asking questions such as the title of this post. “I want that Vacuum thing that goes inside the walls” is probably a common request of a wife whose husband is building them a new home. Maybe your kid has a friend over and that friend happens to see you pulling out a 50 foot hose from your wall. That kid will probably be asking your son/daughter, “what that hose in the wall is” at which point your kid will answer something along the lines of, “It’s this thing that cleans and goes back in the wall”.
We decided that people need to learn some more about Central Vacuum Systems instead of constantly referring to them as “the vacuum system that goes in the wall”.
