We just cleaned our carpet with our new "All-Terrain" Hoover cleaner. A sample of this came with the cleaner and we started with it. We have white carpet and small children (came with the house) and you can imagine what our carpet looked like since it had been several months since we cleaned it. It took stains out of the carpet I never dreamed would come out. When we ran out we switched to the "deep-cleansing" cleaner and it did a great job as well but on some old stains they are still visible (although significantly lighter).
