Status report: After finishing
Bad Mojo I believe I've witnessed (in-game) all the videos from "/movie" folder... except the ones you mention. So, unless we have a case of collective bad luck, they must have been left out, deliberately or otherwise.
Now that I think of it, it must be a glitch - at least in the case of a vacuum. I actually left the table by turning the cleaner on like Jack says, but when I got back (those other way) I found it off. Perhaps the appropriate video
is supposed to be shown, but some programming bug prevents it (same way as the video of releasing the mouse mom not always did play for me).
