Why a general cleaning method is the wrong one here
Ordinary practice includes wiping surfaces, moving small items to clean under them, using damp cloths and running a vacuum with a standard brush head. Each of those is a genuine risk in an equipment room: liquid near powered hardware, a moved patch lead, static discharge from an unsuitable vacuum, or dust driven into an air intake rather than removed. None of this reflects poor work; it reflects a method designed for offices.
The correct approach is to keep the general method out. If the room needs attention, the tasks are defined narrowly: floor only, with a suitable vacuum, no liquids, nothing touched above floor level, nothing moved. Anything beyond that belongs with the client's technical staff or a specialist contractor who works in equipment environments as a matter of routine.
