Walter stood still. Completely. Absolutely. Still.
He listened very carefully and heard nothing. Closing his eyes he tried to remember what he had read in the magazines about expanding his senses.
Eventually he heard it, the tiniest of pings as something very tiny jumped.
Walter opened his eyes and spun around, bringing the vacuum wand up in a two-handed grip as if he were a barbarian wielding a giant broadsword. He kicked out with is left foot, switched on the machine and performed a semi-perfect two handed lunge.
Standing up again he flicked off the machine and listened again. Immediately he heard it, thousands of tiny pings coming from behind him.
He whirled, flipped on the machine and charged into the bedroom with a magical grin on his face, determined to finally eradicate the Space Fleas.
