Crazy huh? Sure, but if your company just launched a commercial vacuum cleaner so quiet that it's called the "UltraSilencer" then what better way to drive that point home than by adding an "iPod dock" (though that's no iPod we've ever seen) and speakers to the damn thing? In fact, Electrolux has taken this Silence Amplified concept so far that they've conducted a lab study to prove that "music assisted vacuuming increases the number of nozzle sweeps, improves the cleaning result and leaves a general feeling of happiness." Duh. Now go check the video evidence after the break.
