Oh good for you!! I know it is so easy to move it around, in the commercial she is dancing around the living room swerving around things, I am not dancing but it does get around! There is only one PRO version of this particular one, It is the Shark Navigator Lift away PRO, it is a white vacuum the regular model that is not PRO is purple. Shark has many vacuums however so being sure it is this particular one is important. This is it on amazon.(there is not much difference in the purple and white in price or in function but the white pro does have a larger debris container, some places have them both for the same price) Shark Navigator Lift-Away Professional Vacuum - Model NV356 you may see a different number than the NV356 if you are buying at walmart or some other store that has their own specific codes. Mine is from walmart so the number is slightly different. Not sure if BBB has a different number. QVC might since theirs does come with added accessories. The suction on this vacuum is amazing. I have a large rug in my living room, that thing will suck down onto that rug and you can not move it, my cleaing lady said oh no what now, well there is a collar that you can turn that allows some air into the suction so that it "lightens up" and then you can move it. So if you find you are stuck LOL that is how to use it on rugs and stuff like that. I have noticed that when I use that sprinkle stuff on my carpets it tends to really get in the foam filter that is where the lift off part connects, I try to remember to clean my filters regularly as they suggest. I am so glad those of you with it are happy. I know I am. here is the official page it probably lists the differences between the pro and regular here the Navigator⢠Lift-Awayî

you must have missed the threads on it here but if you do a search for Shark Navigator lift away Pro on this forum you will find many of them. I have that model and it is with out a doubt the best vacuum I have ever had and I still own a Kirby and a Kenmore but the Shark is pretty amazing. If you want more real reviews there are a lot on amazon Shark Navigator Lift-Away Professional Vacuum the Pro model has a much bigger debris container and this thing will fill it up, it picks up so much more than any of my other ones. you ask about corners this one has the lift off canister so you can use the wand to get corners or high, difficult places. I got mine at walmart for $189 but you can get a Bed Bath and Beyond 20% off coupon and get it there for less. Navigator

Sellers who suspect their product's reputation is being damaged should consider selling direct. Many companies do. What's not cool is begging and bribing to get someone who's spent their money, to take their HONEST review down. Also, you really should be sure to disclose that you received a free or discounted product in return for your review, if and when you re-review. Further, the manufacturer can comment on reviews and explain that the product received could be or is a knockoff and that could explain the poor performance. If the buyer turned down a replacement, that could also be noted.
