Since I had an assortment of Electrolux central vacuum power units and hose sets at hand, I wanted to share the similarities and differences as the product evolved through the past 30+ years. The power units as you will see have remained very similar. Electrolux/Aerus has only ever made one model at a time (first the 1580, then 1590, then several versions of the E130). The hose kits have always used the power nozzles and accessories from their canister vacuum cleaners, and I can't help but express my personal preference for the older style "pistol grip" hose setup vs the newer "gas pump" type that remains the standard to this day.
In this video, we demonstrate why you should use schedule 40 PVC pipe for a central vacuum installation.
