I have been wanting to try these systems for a few years now but was always hesitant. But at the price that was offered for the 2 and 1 I felt I needed to finally give it a try. 
It has exceeded my expectations so far and still have not tried the mopping feature yet. It was super easy to set up in the app and now my house is cleaned twice a week. 
I would recommend this to everyone who has been hesitant to try. It's worth it.
