I was hoping after 3 weeks, I would notice a difference and unfortunately I don't. Back to the drawing board.

Clanky and rattles terrible. I cannot get it to stop and it's multiple places that clank. Belt squeaks, I think the motor itself is rattling. None of this stuff did i assemble. The drive system comes assembled and it's miserably loud. Wouldn't be a big deal if someone would come fix it, but i've sent amazon messages, and the manufacturer, and the third party warranty company. All three of them point the finger at each other. If someone doesn't come fix in the next week, i'm returning it.

I followed the directions reviewers gave here to use the stuff liberally then cover with plastic, wait several days etc. Barely budged the urine but I refused to repeat since the smell of the product itself is worse. It is sickly sweet, smells like the vet and you can't get rid of it. Now you have the smell of perfume over the urine. Its been two weeks now, I have all the windows open in the room all day in the dead of winter and I can still smell the stuff. I would advise using a small bit of it in a room to see if you are OK with the smell before you spill a gallon of it on your carpets.
