I like this robot vacuum.  I like that it creates a map of the floor that I have it on and figures out the configuration of my furniture.  I put it on my second level and haven't had any problems with the stairs.  I also hooked this vacuum up to my alexa app.  I just tell her to start the vacuum up and she takes care of the rest.  I have a dog and a cat so I use this everyday to keep the pet hair under control.  I still use my regular vacuum once a week to make sure the carpets in the bedrooms are good and clean though.  I think these vacuums are definitely timesavers and would purchase one again.
