AVOID Eureka! I have never seen one that didn't huff and puff the dust! Most models are cheap and loud.
When I bought mine, I went to Sears because they had almost every vacuum available on a big display where you could try them out. Now, I am NOT a fan of Sears. I did not buy my Kenmore Progressive because I fell for the salesmans pitch. After much carefull consideration and test driving several models. For the price... (I think I paid two hundred something for the model with a lot of bells and whistles) this one won out hands down!
I have had it for 2-3 years now and it is still great! Of course most all vacuums make too much noise for me, but this one was quieter with a better 'pitch' than the Hoover Windtunnel. It is full HEPA when all the HEPA bags and filters are used. It uses the same 'Windtunnel technology' that Hoover developed - it Sucks the air and dust up and into the bag with the motor/fan being at the end of the line. NOT with the motor at the front end of the line trying to blow the dust and dirt into the bag.
Also, if you vacuum bare flooring and not just carpet. When you put this vacuum on bare-floor cleaning, it doesn't just move the beater bars up while it continues to spin dispersing a lot of the dust and dirt. The beater bar completely disengages.
After I bought it, it ended up on Consumers top picks! I have been satisfied.
I am sure that some of the very expensive vacuums (electrolux) may be better. But, like you, I think that spending enough money to help fund a good part of a trip to WDW just to vacuum my floors is nuts!
So, this was my pick.
Hey Soccerchick - You are right. while I really like my Kenmore... more than the Hoover Windtunnel... My MIL has the Hoover Windtunnel Self Propelled. it is indeed loud. But the self propel mechanism in both forward and reverse is awesome!
