Consumer Reports' view on this vac....
I remember that the original 1974 Eureka version of this power team was rated "unacceptable" by Consumer Reports because the electric cord that plugged into the side of the main unit (coming from the hose) could easily be pulled out. It could be that the original version of this power team allowed the hose to swivel 360 degrees like the original air-only Empress II, and this caused the cord to be yanked out of the outlet. It seems that later versions limited the hose swivel so that the cord would not be yanked out.
