Well my wife had me vacuuming the ceiling in the den (we have a fireplace in that room) turning the couches over and vacuuming the underside of the furniture, the walls and carpet, all the crevaces between the cushions and then she decided to clean all the vacuum cleaners out including the hepa filters and inlet filters with compressed air. The place is spotless but today her head is all stuffed up and she's convinced she has the Corona virus and she's taking her temperature every 15 minutes.
