[This review was collected as part of a promotion.] I really enjoy this product. I use it to clean the seats in my car and for the stairs. There are different brush heads so you can switch it up to whichever works better to get into all crevices.

We used it when one of 3 dogs threw up on the carpet. It took car of the problem very fast, and the clean up was very fast. This is our 2nd little green machine. The other one was over 10 plus years old. Super great little Green Machine.
