I have two dogs both completely house trained but as we know sometimes accidents happen, especially with smaller dogs. When this product was delivered, it was my good luck charm. I needed it just a few days later. Before purchasing this item I would use a spray on cleaner and blot the stain as directed on the bottle which worked. The problem was that it didn't really get up the solution. When I used this product I was amazed at how much previous solution came up with this cleaning. It is very simple to use, did a good job and was easy to clean after use. My only complaint is that I wish the battery would last just a little longer although I didn't need it this time. Glad I purchased it.
