I am going to use it tomorrow . Both my dogs were put down yesterday.  One to old age and one who had cancer in her sinuses and was sneezing blood all over the carpet.  I didn't know I was going to lose both when I  bought this shampooer.  I trust it will clean this carpet perfectly.  Even after the sample shampoo is gone, I  will use vinegar  and dawn.  This shampooer should be great as I only have one carpet.
