While I really like this little robot, the smart maps need a lot of help. Being able to modify a map once it's saved is very important - I want the option to be able to add a virtual barrier across a door or a section of a room without having to recreate a map. Finding it's way home is challenging and at times frustrating. I have the bin at one end of my house and the robot gets almost all the way home, then wanders aimlessly looking for the dock. It ends up in another room and eventually times out. Other times it's able to motor straight home. Lighting is the same and no obstacles block the robot from the dock. I don't like the way it sucks up the fringe on my area rugs. This is were the smart maps editing would allow me to draw a barrier around small objects I want protected.
