It's a heat wave and Leo, like all robots, can't stand the heat! As Sabrina tries to cool him down with a fan, she observes a strange suction phenomenon at the back of the fan. Leo tries to explain it to her, but his reasoning is far too technical, so he calls on the geniuses who decide to build a vacuum cleaner to explain the vacuum phenomenon to Sabrina.
