Euphemism for a man who acts in erotic films - a male porn star.
From the common set-up for cheap porn flicks where a guy knocks on the door of a house, which is answered by a woman (often supposed to be an attention-starved housewife), upon which he says, "I'm here to clean your pool."
Foster so wishes he was a pool cleaner - just look at his porn moustache and mullet.
One who removes cum from a lint filled belly button.
Yo, remember that time steve pool cleaned that nasty chick.
