Hi C.
Well first of I'm a Grandmother of one and a mother of 3 pugs and 1 cat, so when it comes to vaccums I've had my share. I have two in my home which i use a least three times a week. I have the one that i use down stairs and that one is a Kirby Upright (Diamond Edition). The one came with a heavy price tag of $1,600.
It is great and it picks up like no other, however it is so heavy that I can not carry it upstairs. So upstairs i have a Oreck upright and I think that one was $300.00. Let me tell you, it is so light and i can do the staircase with it. I really love it and I can even give my bathroom floors a sweep with it.
My husband and I own homes in and around Ohio and we rent them out, when they become vacant i will clean them and bring my vaccum with me. The Oreck that is, it work's great. I have used many systems in the past and many are not very good out there. When we have to replace carpets in some of the home many of vaccums have failed just by using them on new carpet.
The fibers get all inside the unit and either melt on the beater bars or just fail to get all the new fibers out of the new carpet.
I have tried the bagless and they are useless as you have to replace the filer so often that it become costly and tring to find the filter's have the time is a problem in itself, and cleaning out the the cartriage is dusty and dirty.
I read so much about the Dyson but again I have spoken with many and they do not rate the Dyson that high. I hope i was able to help in some way.
Good Luck,
