In retail, the store is part of the product. Shoppers walk past a smeared window, a dusty display or a grubby entry mat and quietly decide the brand isn't for them. You spend on fit-out and visual merchandising, and a poor clean undoes it.
The hours make it tricky. Stores open early and close late, deliveries arrive in between, and staff are busy serving. Cleaning gets squeezed into whatever gap is left, often by store staff who should be on the floor.
Store and centre managers need a cleaner who works outside trading hours, knows what matters on the shop floor, and looks after the back of store as well. For groups, every store should look the same, whichever suburb it's in.
