I bought this because my friend had an older model and I remember going to a his house (a house of three guys) and the place had such a clean feeling. I knew I needed this. I also have a cat so there is cat hair everywhere and this thing has done a GREAT job. the AI aspect of this model is evident and super cool if you're like me and like to watch it every now and then. I'd love to say I convinced others to make this purchase but the truth is that the product did it itself, it's great. 
Yes you have to change the vaccum and the mop options but it's really not that big of a deal it literally pops in and out and given that I want this product to last me, I clean it almost after every use as it literally takes seconds to clear either chamber.
