If you are moving out of a flat in Wimbledon Village, the cleaning can feel like the last big hurdle. Keys to hand back, boxes stacked by the door, a corridor full of the usual moving-day chaos.

Carpets take a beating in real homes. Mud from a wet walk around Wimbledon Common, a splash of red wine on a Friday night, a bit of pet traffic by the sofa, and suddenly the room feels less fresh than it should.
