What routine cleaning actually is
It's the difference between tidy and clean.
Most people can keep a house tidy. Dishes go in the dishwasher, laundry gets folded, the counter gets wiped. What doesn't happen is the other layer — the film on the backsplash, the dust on the ceiling fan, the grime along the bottom of the shower door.
That layer builds up quietly, and by the time you notice it, sorting it out costs you a weekend. Routine cleaning exists so it never gets that far. Your team comes in on a schedule, works through the same list every time, and the house never has a chance to slide.
The point isn't a spotless house for one day. It's a house that's never more than two weeks from its best.
The other half of it is the team. You get the same one to three cleaners each visit, so by the third or fourth time they already know your home — which room needs longer, where the vacuum lives, that you'd rather they left the office alone. You stop having to explain things.
