It depends on foot traffic and how the space is used, not just its size. A professional office of ten to twenty people usually works well on two or three visits a week, with washrooms and kitchens topped up daily if the team is in five days. Once headcount passes about thirty, daily office cleaning tends to be the more economical option, because soil builds faster than a twice weekly clean can remove it.
Client facing spaces set their own pace. Retail floors, showrooms and gyms are typically cleaned daily, since hygiene shapes how customers judge the business. Medical and allied health rooms need daily cleaning to a documented standard. Warehouses and industrial sites often run lighter, weekly or fortnightly, with amenities cleaned more often than the floor.
A practical test: if you would hesitate before walking a new client through the space unannounced, you are cleaning too infrequently. Most Adelaide businesses start with a schedule and adjust after the first month, and we build that into the written scope.
