Immediate solution! I no sooner got the Pet Stain Eraser out of the box and Kona, our 2 year-old Mini-American tossed her cookies and whatever else might have been contained in her belly and gave me a look like, "Let's see if that thing works!" Fortunately, the battery had a partial charge from the factory and I was able to put the tool to the test right then! I had cleaned up the solids and then sprayed the affected area. It did a great job of deep cleaning and, other than the carpet being slightly damp, the mess was gone! Great product! I've only had it for about 3 weeks now and have used it 3 times with the same great results.
