I received this robot vacuum days ago and I'm so impressed with it cleans all the mess of my furry cat that leaves when she uses her litter box and my kids crumbs. This robot picks up every little tiny single of litter and my kids crumbs. Another, thing that it works with Alexa. It easy to pair , and if you don't have an Alexa you can download the shark app on your and ready to use and put your shark to clean. Another thing that you can schedule a time that you want your vacuum yo start cleaning way to go!
Also I have hardwood floors and some larges rugs  and this vacuum cleans everything it doesn't get stuck and moves through all the rooms easily.
Let me tell you if you have kids or a furry cat or dog this vacuum is a life changing.
Another thing that I would like to add that this vacuum robot is easy to clean just pull it out and shake the dirty. Very useful shark vacuum. I would recommend this 100%
