Actual robot and base are nice piece of hardware but mapping and ability to navigate house are really bad it constantly misses areas and rooms. Our house is open plan with pretty minimal furniture yet still it cant clean a room with anything more then a chair in it. This is one of the better runs! often it skips rooms all together.  if you look at the attached image it missed all of room3 (despite crossing it multiple times) most of room9 , half of room 2 and big piece of room 6. there is nothing blocking or comlex about any of these areas and my old roborock managed all with ease
