Well, my family used to have a cleaning lady (actually, there were two). I say "used to" because they messed up our new shower we put in and my parents got really ticked and fired them but aaanyways...
It's not weird to pick stuff up before hand. My mom used to make my brother and I pick up everything off the floor before the cleaning ladies came in. . If anything, it prevents the cleaning people from misplacing your stuff.
