I’ve had this for several weeks now and am so pleased. 
I’ve had an older robot vacuum for many years using it less and less as time went on. It was loud and inconsistent so I’d gone back to my traditional vacuum. In comes the Shark Matrix…
Set up was a breeze. The unit took about 30 minutes and mapped our home. After that, we set it off on its maiden voyage. She cleaned like a charm, returning once to the dock to “unload” all the dirt and dog hair. 
We now have it programmed to run at night, and although I hear it click on, it isn’t loud enough to keep me up. It does a great job getting into the corners and the technology keeps it running smoothly and not with the jerky back-and-forth movements. This truly is a smart robot machine. 
We’ve not yet had to empty it, but have removed the bin and it is very easy to do. 
I strongly recommend this upgrade if you’re considering it. The convenience and thorough clean is well worth it.
