I was watching a DVD of THE MUNSTERS and the episode was called Grandpa Leaves Home. In the episode, Herman showa Lilly that he has "fixed" her vacuum cleaner( it was a cylinder tank type that resembled a rocket) and as he turns it on to show her dust pours out the nozel part of the hose. it is really cool to watch and see the vac run and the dust fly. Herman says to Lilly, " here is your vac and look it blows dust just as it should!" really funny . The DVD is part of the The complete first season set if any one is interested... I just love the old Munsters....
There's another episode where she is "dusting" (blowing out more dust!) with an Electrolux XXX. I don't remember all the particulars, only that bit and a scene of Eddie (the kid) practicing on the pipe organ in the parlor.
