Waited awhile to review this and still loving bobi.  does a great job on our hardwood floors and has a long battery life.  Seems smarter than  irobot with manuevering around most things and does not pass through the bedskirt which is helpful,  in some cases I put under the bed for a while to pick up dust, but not all of my beds allow for this:)  sometimes leaves puffs of dog hair its collected on edges of rugs, but overall very pleased.
