Loving this robot! And, discovered very quickly that the waste bin feels fast so you gotta keep an eye on that. But I have a question. My house is on two levels. The robot mapped the top level where the charging station is located and when finished it heads back to the charging station. I wanted to do the lower level so I picked it up and took it downstairs and ran it. It mapped over the existing upstairs map however. I don’t know whether or not that’s a problem since I’m so new to this. But I wondered whether it maps every single time it cleans or whether having a stored map facilitates the cleaning in which case taking it downstairs could screw everything up. Any thoughts?
