I have two German Shepherd dogs and I used to struggle trying my best to pick up all their hairs and dirt. Sweeping was not cutting it, and my robot vacuum was more of a hassle than what it was worth. With the Stratos, I am able to get ALL the hair and particles of my floors. I can’t remember the last time I was able to walk around without house shoes. It is a very powerful vacuum and a one stop shop to clean my whole house!
