Daily care is what determines machine life
A scrubber whose recovery tank is emptied and rinsed at the end of every shift will run for years. One that is parked full will develop odour, blocked hoses and a failed pump, and it will fail without warning. The same applies to pads left on a machine overnight, brushes not rinsed, and squeegee blades not wiped. None of that care takes long and all of it is skipped when a shift is running late.
Which means it is a supervision item rather than a training item. Cleaners know how to look after a machine; what determines whether they do it is whether the shift has time and whether anyone checks. A machine inspected at every supervisor visit stays in condition. One that nobody looks at between failures deteriorates predictably regardless of what anyone was taught. Care that nobody checks is care that stops happening on the first busy night.
