Query: Wow!

Bought this through Amazon, on sale for $240 and didn't use it for a couple of weeks. I was trimming the family dog's nails and clipped a vein. I didn't realize it until he took a couple of steps on the berber carpet. I figured this would be the perfect time to try out the unit. My intent was to just do a small spot correction - you know, one pass and then quit. Well, after one short pass, the carpet was so much cleaner I had the do the rest of the room. So after one room I am very impressed. The one gallon tank is an annoyance but it is easy to remove and refill. The same goes for the take up tank. Amazing how dirty the water was. Plus the smaller tank makes it easier to handle. I give it a big thumbs up.
