These words meant nothing to RT-453, it only had sensors. The life of an Auto-Vac was rather bland, a regular schedule of carpet patrol limited to the ground floor of the Hansford home. The home was unsually orderly and clean, two human units...until recently.
The RT recorded a decrease in dust production of almost 45%, also a similar numbers in the area of hair and skin retreival from all assigned areas. The low numbers continued for a number of weeks until the the introduction of the feline. RT-453 had no contigencies for urine and fecal matter.
