Too bad they put wheels on the Connie. I've seen that on a few on here, the old ones didn't float all that well depending on the flooring. Hopefully you can get it to float again. And that hose looks like it might be from a Slimline, Constellation used the Ultraflex hose. The machine itself sure looks clean though.
The Eureka is in beautiful shape too.
Very nice finds on both. It's hard to believe these were actually traded in on new vacuums after all the years.
