Weekly cleaning makes the most sense for busy households with kids, pets, or anyone with allergies. Dust, hair, and kitchen messes build up quickly, and a weekly visit keeps everything consistently clean instead of swinging between spotless and overwhelming.
Every other week is the most popular schedule for couples and smaller families. The home stays in good shape, and quick daily tidying in between is enough to keep it there.
Monthly cleaning works for single-person homes, or as a reset for people who keep up with daily cleaning themselves but want the bathrooms, floors, and kitchen done properly once a month.
Whatever schedule you choose, start with a deep clean. It brings the whole home to a baseline that regular visits can keep up with, and you can always adjust the schedule as life changes.
