I have a vague memory of this cartoon, but I don't believe anything like it was narrated by Ed Herlihy. He did do some voice-overs that were not credited. Mel Blanc is more likely the "Man of a Thousand Voices" as he did so many for Looney Tunes, Hannah-Barbera and other distributors (mostly uncredited). One thing I did find is something produced by Chuck Jones (and voiced by Mel Blanc) called "Dog Gone Modern." (1939). The synopses (from IMDB) says " The Two Curious Puppies visit a model home with a panoply of modern inventions, including an annoying robot that sweeps up anything that touches the floor." It's a Merrie Melodies piece (Warner Bros.) -- give it a Google and see what you come up with.
