Season 5: Episode 115: Humm Vac
Ray purchases a new state-of-the-art vacuum cleaner from an attractive door to door saleswoman and it ignites a housekeeping war between Marie and Debra. Debra is as taken with the new vacuum as Ray once she witnesses all of the wonderful things it can do. That is, until she learns why the saleswoman showed up at their door in the first place. Determined to prove to Marie that she's is just as good at "keeping house," Debra attempts to use the new vacuum to find some dirt, any dirt, in Marie's home. Of course, the results are disastrous.
