I don't have sound at work so the video just appears to be a man waving a pizza slice around before I got bored and gave up. Is there anywhere on the site where it says what it does in writing?
Interesting! I played around with booking a cleaner - I noticed if you try and book a one-time clean for sooner than 48 hours you not only get an error but also it resets the "one-time" process and you get the warning message box up again when you reselect.
And I didn't see anywhere warning me about that period.
I might well use it for my end-of-tenancy clean, though...
