First off, let me say that this machine will probably work well on carpets . However, it is not ideal for padding. A video from Bissell's own website led me to believe that this was not only a carpet spot cleaner but also an upholstery cleaner. While the suction may be at its strongest, it didn't seem to pull water from a small flat spot on our love seat. This got it VERY wet, although it pulled out a small amount of dirty water. Again, probably very well on small, flat areas of carpet, but not on curved or edge surfaces of furniture where the tool head cannot be in constant contact with the surface. If you use this machine to clean a sofa and loveseat, they may remain very wet for a long time. , not what I would have expected from the machine with the strongest suction. Some kind of dampness, yes, not wet dampness.
