What the landlord is actually testing
At review or exit, the question is whether the condition of the premises reflects fair wear or neglect. Those look similar in a photograph and are distinguished by history. A floor that was extracted on a documented cycle and still shows wear tells a different story from an identical floor with no maintenance record, even though the current state may be the same.
That is why periodic work matters more than daily work in this context. Nobody disputes that vacuuming happened. Disputes concentrate on the things done a few times a year: carpet extraction, hard floor treatment, high-level dusting, window cleaning, upholstery. Those are the items with a cost attached at make-good, and they are precisely the items least likely to have a record unless someone decided to keep one.
