Bests & Worsts Reviews from Amazon

I just received 30 minutes ago and assembled in about 1 minute with no need for instructions. I tested it on one carpeted room about 12X14 and it seemed to work very well. I just vacuumed yesterday with the shark nv752 and I filled the dirt cup with hair. I have 2 German Shepherds + 3 cats, so some hair may be new, but not this much in one day. I love my old shark but I have to empty the dirt cup 8-10 times when I vacuum the whole house. 80% carpet and 20% hardwood with throw rugs. Not as much fine powder was picked up as I am used to with the nv752 but maybe I'm getting it down from vacuuming yesterday. I put pictures so everyone can see the difference in size of the dirt cup. That is 90% why I bought the new one. The old one still works fine, I have to say! It was just getting old having to stop halfway through a room and go empty the canister. Also the nv752 has crevices and nooks that would hold the hair and I would have to hand pick some of it out of the cup. If you don't have pets then go with the 752, it works great but If you do have pets then this one is much better. The brush does seem to pull much more hair and doesn't have to have the roller cleaned and cut out hairballs and such. It is a little hard to push, but if you turn the dial to relieve some of the suction it is much easier but that is a good thing, it shows how much suction it has. This could be a premature evaluation as I have only done one room so far and not any hardwood floors yet. If I have anything negative or updates I will update my review. I almost got the pet pro model but it seems the only advantage was a motorized upholstery tool plus almost $100 more. Oh almost forgot, It is quieter than the other as well.
