Oreck Cons
BAGS! are expensive!
My cord (electrical plug) split from the machine.
So now I am using the Dyson. I don't LOVE it like others do. It's ok. It's a vacuum. I will say that it seems to really pick up stuff in the carpet.
But the "filter" that never gets clogged. Gets clogged on mine with dog hair.
It's pretty easy to clean- but I do have to clean it out like once a week.
My oreck was just such a pain to get fixed when it broke- only one place serviced it and it took a couple weeks to get it back. So I opted to get a dyson on sale the last time the cord broke.
Having owned them both- I think I might say try a miele?
