Exactly, like you choose moderators for TMO or tech staff - volunteers with correct skills, assigned by Board (or accepted by general assembly or whatsnot), not elected.

General rule of thumb is that for such tasks, you assign people with correct skills, not the ones that just want to do "something". Ironically, most people interested in doing humble housekeeping tasks doesn't bother to go through some elections, promoting themselves as candidates, etc. At the same time, you're likely to end with 5 vocal Councilors, that are good at doing 20% of "more glamorous" housekeeping, a no one to do the 80% rest, especially, if some of it require specific skills.

Think of it - it would be silly to ELECT every cleaning gentleman/lady in your building, right? Sure, you can choose between few offers, but ELECTION with CAMPAIGN for housekeeping? Seriously?
