Wow, does this shampooer pack a punch. It has way more power than my other non pet Hoover shampooer, which I always thought did a great job. Now that I've compared the two, I'll only be using the Hoover PowerDash Pet Advanced. The suction is almost too strong for my older carpet, as it appeared to be almost deshedding the carpet, but I think the issue is with the carpet itself being old. We had shampooed our carpets one week before this one arrived, but I was excited to try it so I didn't wait. Only a week later and I seen how much my other one has been missing! There was one stain I've been trying for months to get out, to no avail. But two swipes over it with the Pet Advanced, and it was gone! I would absolutely recommend this one!
