the S5 refuses to map the left side of these two adjacent rooms. As shown, the cutoff for each room occurs on the same plane. The S5 will not cross over the straight edge of the yellow line in either room. I have divided the house into separate room areas, brought the s5 to the rooms and had it clean them, and as seen in this attached picture I added invisible walls to create a path the leads to the two rooms from the dock at the other end of the house and instructed the s5 to do a full clean which I thought would map the two rooms while ensuring the battery does not die as the S5 cannot cover and map the whole house in one battery charge. there are no steps, stairs or sunken rooms in the house - all single level home athough these two rooms are carpet (light colored) while most of the rest of the house is hard floor. I would appreciated any help! thanks.
