Well, Owen, we'll see.
Perhaps some day.
It's an old house. Both floors have 10 ft ceilings, there's a "staircase".. the hallway, from bottom to top is 20 ft. The 1st floor has the entranceway (stairs), formal living room, library, family room, 20'X 25' kitchen, dining room, full bathroom, and 3 - season room.
The 2nd floor has a full bathroom, 4 bedrooms, one is the cats' apt, 20X25'. It is the future Hoover gallery. It was suggested that the "pipes" could go through closets; 2 inlets on each floor.There are 4 cellars, so under access is easy.
Regardless, I love the quadraflex nozzles.
Tom A. stressed the inlets have the "logo" on them, of course.
At this time, I can find more practical things on which to spend that money.
But, I SO appreciate your input.
We'll see..........................
