Advert/TV commercial characters are scripted to be clueless. That's a prime requirement for the pitch to work. Can you imagine a character, when presented with a product to solve her/his cleaning problem, launching into a Lizzie May* diatribe?
Anyhoo, that Dad clearly 'lost' his wife, in that silly absent-minded way advert characters have: he must have left her somewhere, perhaps forgot her in Vegas when they were there last year, ... (make up your own commercial world backstory).
edited to add: *Lizzie May = TV commercial-inappropriate clueless.
