This is the Third Hoover Carpet Cleaner that we have purchased. The Twin Brushed are much more effective than either of the previous models that we have purchased. I really like the Stain Spotting Handle. The Unit is not as loud as previous units and provides a deeper clean also. My only problem with when I bumped something on the floor and it dislodged the clear cover on the front of the unit. This caused the cleaner to stop picking up water. It looked ok, but I had to stop and really examine the unit before I found the and reseated the cover. It worked great then. A major improvement over earlier units.
