When I came up the stairs to the studio this morning I heard talking. Was there someone up there? Did I leave the computer on with a video going?
No, it was the Roomba, complaining that it needed to be recharged.
When I leave the studio at the end of my day, I sometimes set the Roomba to vacuuming the room, as I did last night.
Unfortunately, some of the blocks on my design wall fell off and the Roomba sucked one up causing it to cease operating, unable to continue and call for help.
