Read the installation list as a list of working conditions
Most supplier installation notes name the same handful of items: a power point, a water inlet, somewhere for the run-off to go, floor space, and a place to keep the unit. Those items are not the requirement. The requirement is what each one has to make possible on a particular working day in a particular room. A power point that exists but sits behind a parked trolley does not meet the condition. A drain that exists but is thirty metres from the duty does not either.
Write each item as a sentence about the job, then test it at the position where the work actually happens. That sentence, not the specification line, becomes the acceptance check when the machine arrives.
Start the survey where the routine is performed, not where the machine will stand
Walk the existing cleaning routine and mark the surfaces on it: the ones cleaned every shift, the ones cleaned weekly, and the ones that keep slipping because access is awkward. For each group record the deposit being removed, the distance an operator must cover, and whether the work happens while the room is in use or after it is cleared. A fixed unit changes that map: the hose length becomes the working radius, and everything outside it needs a second decision.
This is the step most installation lists skip, and it is the step that decides whether the other answers are right. Compare the options against that map rather than against each other; the commercial steam cleaner range is split between installed units and mobile ones, and the split follows the routine, not the specification sheet.
Power and isolation: ask who is allowed to make the connection
The useful question is not only what supply the machine needs, but where that supply is, who can install it, and what protects it. Ask for the working voltage and the heating load as they apply to the exact unit quoted, then have the answer checked against the circuit at the position of use, including the distance of the run and the protection already fitted there. Extension leads and temporary adapters are a workflow symptom: they mean the installation was not planned for the route the operator walks.
Isolation belongs to the same conversation. Whoever switches the unit off for maintenance, and whoever can lock it out, must be named before commissioning; otherwise the machine becomes equipment nobody on the shift is authorised to touch.
Water in and run-off out: the two items that decide where the machine can live
Steam cleaning consumes water continuously while the job runs, so a supply point that is inconvenient becomes a stop in the routine. Record where the feed will be, how far the operator walks to it, and what kind of fitting it ends in. Published inlet details belong to the specific model and do not transfer between machines or between sites, so get the fitting, the connection size and the feed condition in writing for the unit on the quotation, and check them against the pipework you actually have.
Run-off is the mirror image, and it is the item most often left to the installer. Where the water goes, what it carries, what intercepts it, and who inspects it afterwards are the site's answers, not the equipment supplier's. Kitchen back-of-house water carries grease; a wash area carries soil and oil; a production floor may have no drain at all and needs collection as a scheduled task. Put the route on the plan, and cost it as part of the cycle time rather than as a surprise on the first working week.
Fixed or mobile changes what the workflow can plan for
A fixed unit gives the routine a station: the supply, the drain and the storage are solved once, and the operator works outward from one known point. The cost is reach. A mobile unit carries the job to awkward surfaces, but the routine then has to plan for refilling, for charging or cable management, and for where the unit is put when the shift ends.
On the installed side, the published rows for the fixed steam cleaning machine on this site are a working example of what a station has to answer: tank capacity and its material, the water inlet arrangement, the footprint including handles, and the dry-steam and wet-steam modes. Those values describe that page's machine. Read them as row labels to have filled in for the unit you are quoting, never as figures that carry over to another model or another building.
Access, clearance and the delivery path are part of the schedule
Walk the route the machine will take on delivery day: door width, corridor turns, thresholds, lifts, floor condition, and whether anything has to be removed to get it in. Then stand in the finished position and allow room for an operator, for hose movement, and for a technician to reach the service points. A machine wedged against a wall slows every job and makes routine maintenance something to schedule around.
Note this too: a unit relocated after delivery reopens the power, water and drainage answers. Treat any move as a change of installation, with the same sign-off.
Spares, consumables and service belong on the same sheet
Ask for the wear list, what is replaced by the operator, what by your own maintenance team, and what only a manufacturer technician may touch. Ask what each part costs and how long it takes to reach site. A sealed nozzle with no local stock is not a spare-part question; it is an idle-workforce question.
Tie the service interval to what it protects and record who is responsible for keeping it. Then put the consumables in the same budget line as the machine, so the schedule is not the thing that runs out.
Put the installation answers on one sheet and score every quotation on it
Take the headings above, send the same sheet to each supplier, and score each answer as stated, qualified, or missing. An answer that says standard means the cost appears later, after the machine is on site. Where your site cannot meet a condition, that gap should appear on the sheet before the order, not during commissioning. If a duty falls outside what the catalogue covers, ask what can be built around it; customized steam cleaning equipment starts from a brief of the surfaces, the deposits and the room, which is exactly the information this survey produces.
Prove the plan on one bounded job before it becomes company policy
Run one agreed trial on surfaces you can see and photograph, with the shift pattern that will normally be used. Time it, and write down every stop: refilling, moving the unit, waiting for power, clearing the area, letting surfaces dry. Then compare what happened against the acceptance sentences you wrote at the start.
Decide the stop condition before the trial starts, so a poor result ends the trial rather than starting an argument. A pass turns into a one-page method per surface family: what is cleaned, with which mode, by whom, and what has to be dry before the room is handed back.
Train and hand over in the same room, on the real job
Handover is not a presentation. Have one operator run one real job with the supplier present, and record what the operator had to work around. Then record who else needs the same training, what it covers, and how the next intake learns it. The handover should leave behind a written method for your surfaces, the list of surfaces to keep away from steam, and the procedure if a protection trips mid-job.
What to close out, and what still needs a signature afterwards
Every item on the installation sheet should end with a signature, a measurement, or a demonstrated job. Nothing should be left as to be confirmed on site. After start-up, review the routine at an agreed date: which stops actually happened, which surfaces are still slipping, and whether the station position matches the route operators took.
That review is the last installation question. A machine that fits the workflow improves it quietly; a machine that does not shows up as extra walking, refilling, and unfinished duties long after the quotation is closed.
