Thirty minutes is enough to get the house presentable. The trick is not to clean faster, it is to clean in the right order and never go back over yourself.
Tidy first, clean second
Five minutes picking up what is out of place saves fifteen spent steering a cloth around objects. One basket per room does it: collect everything, put it away at the end.
Top to bottom, always
Dust falls. Wiping the worktop before the shelves means doing the worktop twice. Shelves, then furniture, then floors.
Wet it and let it work
Put product in the toilet, the sink and the hob at the very start. While it works, do everything else. Coming back five minutes later takes far less effort than scrubbing dry.
A bathroom in six minutes
Mirror, basin, toilet, shower, floor, in that order. A separate cloth per zone stops you spreading what you just removed.
What comes last
Vacuuming and mopping are always last, working backwards towards the door.
For anything that needs more than thirty minutes, the OSCAR app has cleaning with a fixed price before you book.
