Hang on
I thought this forum was for the preservation of vacuum cleaners, not just blatant destruction as seen in the above video's?
I'm surprised that many people just throw away Numatic's, as they are easy to repair and parts are widely available.
There are a few images that would spring to mind as 'sad' vacuums, those that have been abandoned etc. I've seen an image of an abandoned warehouse with an Electrolux 502 machine in ti, and there are several images of the Hoover factory in Cambuslang once it closed. I believe the Cambuslang pictures are on Flickr. Even though the Cambuslang pictures are not of cleaners themselves, they are of the factory that produced great vacuum cleaners.
