I love this for vacuuming all of my stairs but it is clumsy.  There is no easy way to lean it against something and it falls so easy. I’ve broken the battery cap and the button to remove the rollers in the first couple of months. The V11 is more stable and doesn’t fall over. I hate having to lay the vacuum down every time I need to free my hands. 

Works great on hardwoods and tile. Not good for any sort of carpet/rug. 

It’s nice and lightweight, I like it way better for doing my four flights of stairs than my V11.
