The only Hoover Convertibles I truly like are the ones made after 1979 when they introduced the Type A bag. The older Convertibles use terrible Type C bags that are not worth my time, although the looks of the older models nice. The 5amp motor in the newer models great at deep cleaning and their sound is fantastic! It starts up with this bong and then goes into a low grumble that is simply musical. The 5amp Convertible motor is the only motor I can say I enjoy and look forward to listening to.
Anyway, vacuumfreak, I believe your Eureka has the 6.5amp motor, right? If that is the case, I have to say your Eureka would outclean even my beloved 5amp Covertible. The Vibra-Groomer and the Dial-A-Nap make a huge difference as the Covertible's height-adjustment is located in the rear and sometimes prevents the vacuum from locking onto the carpet.
