I have an S6 MaxV and I am using the multi-floor feature. When I use the vacuum on my main floor, where the dock is, I never have any issues.
When I use it on my upper floor or my basement, which were mapped without the dock, I am having some very inconsistent behavior. Sometimes, when asked to vacuum an additional floor, or just some of the rooms on the additional floor, the vacuum completes its task, returns to its starting point, and then stops (announcing that it cannot find the dock).
Other times, unfortunately, it instead starts driving everywhere it can possibly reach, looking for a dock that is not there (and was never there, since the floor was mapped without a dock). This is particularly frustrating when I have it only vacuum selected rooms on that floor, since it does not limit itself to those rooms when looking for the dock. There was a reason I did not have it go in those other rooms this time!
I am on the latest firmware, and I can't find any pattern to understand why it is behaving correctly sometimes (returning to its non-docked starting position and stopping there) and other times it is futilely looking for the dock.
Is there something I need to be doing differently? If this is a bug, will it be fixed in a future firmware update?
