I got this vacuum as a Christmas gift this year. It was very easy to put together and the instructions were great. 
There is, as I saw a few other people say in their reviews, there are only TWO docking mounts for the extra attachments and it comes with THREE. Easy fix. I used Velcro and it works PERFECT for keeping it attached to the vacuum without losing it!!
I cleaned the beejesus out of my apt and I just can’t say enough good things about it. I have one large dog and the pet hair is no joke around here!! But no more!! I can waller and roll on the carpet with the dog and still come up clean!!
It’s easy to carry without being too heavy and since the cord is still new and needs some mild stretching due to use, it still works when it falls over.
Very easy cleaning of the parts and pieces. 
Can y’all tell how much I like this vacuum??
I would definitely recommend it!! I’m so happy with my Shark!!
