I bought this model because it can map the area it is in and that was very successful. No more missed patches of floor! The main issue I have is the internet connection. It will not stay connected to my home network for more than 24 hours which means I cannot schedule regular cleanings. My second complaint comes in the power department. I like that you have the option of setting the strength, but all of the settings are not strong enough. Since it maps the floor, it performs less passes over an area which means that the suction needs to be top notch. Sadly, it isn't and I find myself having to pick up many particles the vacuum passes over. My floors look clean-ish but I want them to look clean. I do love the bin that empties the robot and love that it will continue to clean after it unloads the dust bin. Please work to fix the internet connection issues.
