When a cleaning request mentions a "vacuum function", two very different things may be meant: a machine that suctions dry debris, or a recovery system that picks up the water left on a surface after washing. In a steam-cleaning context the second meaning is usually the one that matters, because steam and hot-water cleaning always leave moisture behind. A quotation based on the wrong meaning produces equipment that cannot finish the job.
State first what has to happen to the water
Write down how the surface should look at the end of the task. Should it be dry enough to be handed over immediately, or is a damp surface acceptable? Is the run-off allowed to flow to a floor drain, or must it be collected because the area is in use, on an upper floor, or subject to hygiene rules? That single answer decides whether you need recovery or simple spraying.
Separate dry pickup from wet recovery
Ask yourself whether the function must remove loose particles before cleaning, or liquid after cleaning. Some installations combine both in one unit; others need a separate recovery vacuum. Tell the supplier which one you expect, and say whether the same machine or operator should do both steps.
On our own vehicle-cleaning range this distinction is built in. The Fixed Steam Cleaning Machine PowerDe HW02 page lists dry steam, wet steam and a vacuum function together on one 220 V unit, with vehicle exterior work at gas stations and parking lots, interior vacuuming and disinfection, and engine-compartment cleaning named as its tasks. If your site needs all three steps in one machine, say so explicitly. If you only need to suck up water, ask whether the vacuum on offer is meant for that at all.
Include these details so the proposal matches your site rather than a general brochure:
A function name on a datasheet is not a specification. Request the figures behind it: how the steam mode is selected, the operating temperature and pressure the unit states, the tank capacity, and what protection features are fitted. For the HW02, our published detail page gives 6 kW heating power, 160° steam temperature, 0.8 MPa vapor pressure and an 80 L SUS304 tank, with tap-water inlet and 220 V working voltage. For a different model, ask for the same list of figures and compare like for like; where a value is not published, ask for it instead of assuming it matches a sister model.
Tell the supplier about limits you are working under: water use, detergents you are not allowed to apply, hygiene or inspection requirements, and access constraints such as narrow aisles, indoor garages or no floor drains. Constraints of this kind often change the recommended configuration rather than the model. If your duties go beyond the standard range, describe them and ask for an assessment — our team covers

One line on water handling. One line on the object and the soiling. One line on power, water and drainage at the point of work. One line on daily volume and shift pattern. Then ask for the specification figures behind every function you named, in writing. An enquiry built this way gets a comparable answer from every supplier, and it gets one that fits the site the machine will actually stand on.
