A suction cup could lift a bowling ball but will do dick all about the crap on your floors. Lifting a bowling ball is about static pressure while lifting a bunch of small things is more about generating high airflow. Based on this, I wouldn't be surprised if a vacuum cleaner designed to be able to lift a bowling ball is worse than one that didn't try to do something like that and just focused on shit a vacuum is supposed to suck up.

Though maybe a vacuum that could lift a bowling ball would be better for sucking a dick. Did they advertise how well it handles fluids in addition to the blowing balls? Maybe it was a vacuum like a magic wand is a back massager.
