I brought my robotic vacuum cleaner over to clean while I was doing a 3D print last night around midnight.  I used compressed air to dust and left the building for about 2 hours to let Suki clean up.  When I came back, it wasn't at the charging station, and I couldn't find it.  If anyone finds it, could you please put it in a conspicuous place and post a reply here to let me know where it is?
