I was interested in the Shark Matrix robot vacuum because our dog leaves kibble all over our home and was sick of stepping on it! Setting up this unit is pretty simple. It does do a good job of picking up crumbs and pet hair from the floor. I would not totally replace my battery run shark stick vacuum with it, but it works well in addition to it in our home.  I will say that our dog is not a huge fan of this robot when it is running and other pet owners should keep this in mind.
