The best housecleaner I've ever lived with was a roommate for a year or so in the 90s (male) - he'd worked for a housecleaning company a couple of years before when he was desperate for money. He cleaned in places I didn't know existed! Honestly, who gives a shit about the tops of window frames? Only someone who's paid to care.

I have the classical boy problem of "not seeing dirt" too. I was never trained to recognize it, because the house I grew up in--it was never filthy exactly, certainly never unsanitary, but it was always cluttered, because both my parents had better things to do than scrub every frakkin' day. And that's fine to me! As long as it doesn't stink and there's no bugs, who cares?

(And yes, complainers get to fix it themselves. :D)
