The most important part of cleaning is to schedule cleanings based on check out, not check in. In other words, as soon as a guest booking happens, schedule a cleaning (either yourself or a cleaner) for the time the guest checks out, typically 11AM. That way, even if you get a last minute same-day booking, the unit is always ready to go.
Let us know if you have any questions - once you've got the checkout-based cleaning schedule down, same day is a breeze!
