Bought this unit two years ago and still cleaning! I've owned three different carpet deep cleaning machines over the years and this model by far outshines all of them. Not only does it have the classic upright deep cleaning function, but the bulk of the unit can be lifted up and out of the base of the cleaner by a handle... and voila! It's also a portable spot-cleaner as well! It's like seriously having the best of both worlds! While I prefer the upright cleaning function most, I found the spot-cleaner perfect for reaching pet stains located in corners of carpeted rooms or on carpet directly up against the base of a wall -- while the whole unit in its upright position can't be pushed all the way up to the wall, the spot-cleaner function allowed me to use the sprayer to reach every spot because I could manipulate the sprayer head and brush in any direction or angle I need to in order to reach where I need.... Thank you Bissell!
