Been working on this restoration for a while. It was challenging and time consuming. Sorry for the large upload gap; I’m still alive. This thing is a marvel of early 20th century engineering. I spent hours trying to find another one made by the same brand online and couldn’t find anything. It’s a mechanical bellows powered suction + carpet brush sweeper. Incorporating actual vacuum technology along with the sweeper, this thing was truly ahead of it’s time. During this restoration I re-engineered / re-mastered a lot of the original designs so it’s not really a restoration as many smart people in the comments will probably point out.
