If you are too young or too old to know what the item in the lower left of the first panel is, it’s an iPod radio dock. I had bought it (years prior to making this comic) for my iPod Classic, which at the time was the first iPod that could play video. I can hear my smartphone scoffing.
(In not too many more years, I suppose I will also have to specify that this comic is referring to a hand-propelled vacuum cleaner, not a robot vacuum.)
Comic from 2013 (so old!).
