Naaman, I just noticed your signature. I think that your spending too much on scotch and bourbon and not enough on rye.
On topic, I love my Miele. It's by far the best vacuum I've used.
Bissell makes interesting products. Unfortunately they are always under-designed, under-built and so are "under-realiable". I have a Spot Bot that is fantastic when it works. It's a neat idea and product. Unfortunately I've already had one replaced under warranty. My cousin has had one replaced. When I talked to the guy at the repair facility, he said that they are very unreliable and have gotten a lot in. Bissell doesn't even try to fix them, they just send out a new one. I guess that they make enough money on the sale to still make money giving 2 or 3 during the 1-year warrant period.
