For residents, the home is where they eat, sleep, see family and spend most of the day. A musty lounge, crumbs left on a dining chair or a grab rail that hasn't been wiped is part of their daily life, not just a facilities issue.
What usually goes wrong is consistency. The cleaner changes from week to week, tasks get dropped on a busy shift, and nobody can say for sure what was done yesterday. Facility managers end up checking the work themselves, and families start raising concerns at the front desk.
Residents feel the disruption too. A stranger in the hallway, a floor polisher running through afternoon rest or a cleaner who never says hello can make someone feel less at home.
