I love my new corded Shark Stratos vacuum! First of all, the cord is long,so I can almost vacuum my entire house with not moving the plug. It truly doesn't wrap hair around the brush roll,which is awesome in my book because I have long hair and am sick of cutting it off of the brushroll on my other vacuum. I love the attachment,  it works great on my furniture and stairs, it has very powerful suction. I am also in LOVE with the odor neutralizer!  We have a dog and after using our previous vacuum for a while it develops an odor...the odor neutralizer in the Shark stratos eliminates that and puts off a refreshing scent while you vacuum your home!
