Pat Buttram, aka "Mr. Haney" of Green Acres fame, guest-stars in this episode as an old hermit whom the emergency team must rescue from a cave. Also: a chemist loses consciousness in a burning warehouse laboratory; and Dr. Morton (Ron Pinkard) ministers both medically and emotionally to a one-time popular singer. The title of this episode refers to a new floor-cleaning business, concocted by Roy (Kevin Tighe) and John (Randolph Mantooth). ~ Hal Erickson, Rovi
