I have two dogs & I just got my Deep Clean Lift-Off Pet Carpet Shampooer. I am a handicapped 65 year old women. I have severe back problems. I have been pleasantly surprised with the ease of operating this machine. It has left my carpets looking wonderful. My dogs have had their fair share of "accidents" on my carpets. The shampooer has removed those stains as well as plumping up this old light colored carpet. My suggestions are: easy removal of brushes for cleaning & better water drainage spout on the "dirty water" tank. Great product!!
