I have had my Kenmore upright for 2-3 years now, and I really love it! Now, believe me, I do not usually recommend Sears products at all... But, when I needed a Vacuum, I test drove them all. It works great, Is completely HEPA air clean. (PS: cheapy vacuums may say this, but especially the Eureka, never saw one that did not huff-and-puff the dust!!!) And it was not as loud as many other vacuums. This is a great vac... I read after I bought it that these top of the line Kenmores were like at the top of the consumer reports lists. I think we payed $188.00 for it, and it has been worth it!
PS: I like the ones with bags better than bagless... Seems that really helps make it HEPA clean. Also, especially if you want to use this on any wood or tile flooring, make sure the vac is truely bare floor cleaning. some only lift the beater bar/brush, but it still spins, blowing and dispersing the dirt and dust just as much as it is vacuuming it. On my Kenmore, the beater bar/brush completely disengages when set on bare-floor.
Hope this helps!
