I am in love with my Shark AI Ultra 2-in-1 Robot! It cleans so well my floors have never looked better.  It picks up hair and debris so well.  My hardwood floors look amazing.  It is very easy to setup and love that I am able to schedule using the app.  It is very quiet too.  The Shark AI Ultra 2-in-1 Robot has made my life so much easier.  It works better than my old vacuum.  I absolutely love it and highly recommend Shark AI Ultra 2-in-1 Robot! You will be amazed at how clean your floors will be and how much of a time saver it is.  I LOVE IT!!
