We had the Bissel ProHeat, for the past year.
LOVED it. We were housebreaking a puppy, with wall to wall carpet kind of loved it. Raising a super energetic 6 year old boy in need of a bath kind of loved it. Husband and all of his friends playing rugby in the mud kind of loved it.
It worked FANTASTICALLY, actually easier to use then the vacuum...(although you DO have to vacuum first). There was a time where I was using it once a week.
Only 2 problems:
1. It's broken. First the attachments went. Then last week the whole thing quit working. I've kept it scrupulously clean...so it's not that.
2. I can't find anyone in Seattle who repairs them. NO ONE I've called or gone in to see will touch Bissels. Apparently the common gripe is that they're always full of water, hair, and dirt.
So it's a fantastic machine, when it's working. When it's broken? Right now I've got a couple hundred dollar paperweight. I even gave up and took it apart myself, in desperation, to see if I could find an obvious problem. Nope.

Someone just got me the name of a shop that is certified and willing to work on them up in Everett!!! Huzzah.
