OK - I won't repeat what everybody else has said in their reviews. This is a great vacuum with lots of power. I had a Dirt Devil bagless which worked just as well until it lost suction power. I am going to review the attachments - no one talks about those much. This refurbished model came without a scratch on it and looked brand new. What everyone should know - ALL the DC17 vacuums are THE EXACT SAME vacuum- same motor, technology, air filtering, etc., everything is identical except they make the top a different color.. It is the attachments that are different for each DC 17 model. So, depending on the model you get, the attachments will vary. EVERY dc17 comes standard with a crevice tool, a round brush tool, and a little furniture tool with red strips on it- like the old fashioned lint rollers- these three attachments fit on the side of the vacuum. The Animal model comes with 3 extra attachments, a bag of carpet crystals which you pour on your carpet and vacuum up, and a bottle of carpet spot remover. The 1st attachment is the mini turbine head. This is very neat! It is like a portable vacuum and you can even turn off and on the roller (pull out the red button on the side). This works for furniture - I used it on my cat tree (which is 5 feet high and shaped like a real tree) and it works great, and on the rocking chair where my cat sleeps. You can also use it in corners where the vacuum is too large to fit without having to move furniture. The 2nd attachment is the low reach floor tool. This is a large attachment with stiff bristles - it doesn't roll or do anything. I found it pretty useless - tried it under my bed and a dresser but the attachment is so large and the suction comes from a hole in the middle so it doesn't work well unless you go over the area at several angles and several times. The 3rd attachment is a brush tool which looks just like the one you already get except it has plastic around it making it bigger and square. This is for stairs I guess? I don't have stairs so I used it on my bookcase and my books - seems to work well as the bristles are fairly soft. I would also use this on delicate furniture fabrics like suede or linen. There is a certain learning curve to using the attachments and getting used to how the vacuum works with them. You basically pull out the handle from the middle of the vacuum and an aluminum rod appears - the attachments go on the end of that. OR, you can take that off and attach them directly to the flexible hose. The hose does stretch pretty well so you have about 5 feet to work with here. The aluminum rod is useful for overhead jobs because it doesn't bend. Great for cleaning the ceiling or cobwebs or the top of book shelves. Note of caution - the first time you vacuum it will look like you are picking up a lot of stuff - BUT the suction is so powerful it pulls up carpet fibers - LOTS of them. Obviously, these are loose already, but it is a little shocking. The next couple of times, it isn't as dramatic. This probably depends on your carpet nap as well, but even with a no nap hook rug, it pulled up a full bin of fibers. OK, thanks for reading this far - I would most definitely recommend this vacuum to all if you can afford it. The attachments for this animal model are a GREAT addition and would cost over $150 if purchased separately. A last note - I have TERRIBLE allergies and this model has helped tremendously. I was going to get the allergy model but when I realized it is THE SAME vacuum and only comes with 3 small extra attachments, I went with the animal model.
