I am very much impressed with this robotic sweeper.  First, it feels well made.  It has a simple start guide which I really liked.  It did my whole house in one battery charge (of course I have a small house).  I did have to pull up throw rugs (any rugs I normally have to pick up to vacuum) It has a little bit of a hard time over some thresholds. It really did a great job.  I can't wait to see how the mop works.  It made it back home to it's charger.  I love it!
