Vintage 1970s / 1980s Nilfisk GS80 Vacuum Cleaner

Not entirely sure of the age of this bad boy. They had a long production life from the 70s to the 90s; if you know the exact dates please let us all know in the comments. My machine is likely 70s / early 80s due to the fact it has a woven hose. Let's take an in-depth look at one of the best vacuum cleaners ever made and identify some commonalities between it and the lesser quality Hoover Freedom! Enjoy :)
