OT but my irritation is boiling over.

Whenever this important topic of hospital cleaning is mentioned on the
news we are shown images of corridor floor being cleaned.

Perhaps because that is the dirty part. Not only is street dirt trailed in
on feet, but all the bits of human skin and hair, with their attached
bacteria, end up there too.

What I want from a hospital cleaning service is: Clean equipment, clean
door handles and light switches, taps, toilet seats, chairs, beds,
cupboards, bed tables, etc - the things that people can touch with germ
covered hands.

Human to human contact is generally a much greater risk. When I used to make
medical devices, the staff did not need to wear gloves because the amount of
bioburden transferred to the product from their hands, which we tested on
every batch, was at least a couple of orders of magnitude below that needed
for successful sterilisation. It was not unusual for the lab to be unable to
grow anything from the hard surface swabs taken in the room.
