I purchased this robot vacuum about a month ago. The mapping feature doesn't seem to be working as advertised. After 17 days of daily vacuuming the mapping feature was not complete nor accurate with our house layout. I reset the map feature and am waiting for it to complete. The vacuum pattern does vacuum in parallel patterns but not aligning with the walls. It has stopped several times in the middle of a room and lost it's power and had to be placed on the charging dock. 
I have had your competitors botvac since 2015 with very few failures and have had repairs 2 times in the 5 years. It sure would be nice to be able to use the room map feature but haven't got that far yet. Sure would like some help and advise with making the mapping function usuable. Seems to clean well.
