Condition before method, and method before machine
No honest configuration starts with a model. It starts with a walk. A supplier who is helping a site configure this variant will ask to see the surfaces, not a description of them: the floor coating and its age, the kerbs and thresholds the machine has to cross, the doorways and pillar spacing it has to pass, the slope of the ramp, where wash water is allowed to go, and where a tap and a power point exist near the work. The published page for this machine lists a footprint and a note on automatic movement, so those same measurements are the first thing checked against the site's own openings, in metres, on paper, before anyone talks about cleaning results. If the route fails on paper, nothing downstream matters.
Second, the work is described in the site's language rather than in cleaning vocabulary. "Wash the underground car park" is not a specification. A supplier worth hiring will turn it into a surface list: ramp and driving aisles, parking stops, wheel stops, columns and the lower metre of wall, lift lobbies, refuse-room floors, goods-lift thresholds, any oil-stained patch and its cause. Each row then receives a condition note and a reachability note. That list is what the configuration is written against; a quotation written against a floor-area number alone cannot be checked later.
The battery-less version is a split scope, and the split has to be written
The product page states the arrangement plainly: "Working Voltage: 48V Mobile Battery", with the remark "Customer provided batteries". That single remark is half the configuration. The supplier's scope ends at a machine that expects a 48 V mobile battery; the site's scope begins with the battery itself, and a good configuration document names an owner for every item that lives on the boundary: which battery pack is being used and what its connector is; the cable set and how it is protected where the floor is wet; the charger and where it may stand; a dry, ventilated storage place; the swap routine and who performs it; what happens when a pack is flat mid-shift; how packs are rotated, tested and eventually replaced. Every one of those lines needs a name against it. A configuration where the boundary items have no owner is not a configuration; it is a purchase order with a footnote.
A supplier who can help here is useful in a specific way: they have seen which arrangements fail. They will ask whether the site's packs are the same model as the ones used on their other jobs, whether the site has an electrician willing to confirm the charging circuit, and whether the swap can be done by the same people who clean or needs a second key holder. None of this is a sales conversation. It is the difference between a machine that works on day one and one that works in month eleven.
What a written configuration for one site normally contains
Ask for the configuration in writing, and ask for it as one document per site rather than a general brochure. In practice it covers the following.
Surfaces and areas. The surface list from the walk, grouped by area, with the deposit named on each row and the method chosen against that deposit rather than against the area as a whole.
Mode selection with an exclusion column. This machine's page lists three cleaning modes: hot water, dry steam and wet steam. The configuration states which mode is used on which surface, and equally which surface is excluded from which mode. A mode table with no exclusion column is not usable by an operator on an early shift.
Reach and geometry. Where the machine stands, how far the hose and the lance reach from that position, what has to be re-positioned, and which parts of the route are tight. The page's "mode of movement: autonomous driving" and its listed length, width and height get tested here against kerbs, speed bumps, drainage channels and the turning space at the end of an aisle.
Water supply and the inlet. The published page records a tap-water inlet with a four-point internal-tooth joint. The configuration records the actual tap at this site, its thread, and the fitting that joins the two; it repeats the clean-water tank capacity as the page states it, and names the drain the wash water may reach. In an indoor garage that outfall question is usually harder than the supply question.
Electricity and cable protection. Cable routing in a wet area, protection where vehicles pass, and the state of the power point at the point of work rather than across the yard.
The published protective features. The product page names leakage protection, short-circuit protection, high-temperature protection, high-voltage protection, water-shortage protection and a high-voltage explosion-proof item. These belong in the configuration as named features of this machine, each to be confirmed in service - not as a count, and not as a guarantee.
The boundary list. The battery-side items from the section above, each with an owner.
An operating routine. Which areas on which day, in what order, with what hand-back state - dry floor, no standing water, no blocked channel.
The information the site has to supply
A supplier cannot configure this variant alone, and any supplier who claims otherwise should be questioned. The site owns: the floor construction and coating type, and any repair history; permission and drainage constraints, including whether washing is allowed at all in a basement car park and on what condition; the battery packs, their management and their charging place; shift times the work has to fit inside; access restrictions, security clearance and insurance conditions; the existing cleaning routine and what it currently costs. Written as row labels for the exact site, these answers are what turn a product page into a proposal.
The site should also state the constraint the page cannot answer. For example, whether a battery can physically be carried and swapped by the cleaning crew, whether the building manager will allow a wet floor for a defined window, and whether the site's own tap has the thread the inlet expects. Those three questions decide more than any brochure comparison.
Ask for the figures for this unit, in the page's own row names
A product page summarises; it does not contract. When the configuration arrives, ask that the deciding numbers be written as rows for the particular unit being quoted, using the row names the page already uses: working voltage and the remark that accompanies it, heating power and the heating element described, box volume as the clean-water tank, the water-inlet row with its fitting, the dimensions row with its automatic-movement note, and their mode row. Then ask, in writing, for the rows this page leaves out: the temperature and pressure at the nozzle rather than at the generator, how long a given battery pack runs before the swap, the charger output, the hose and lance lengths, and the accessory list. If a row comes back as a category average or as "as per range", treat it as unanswered. A supplier helping with configuration should expect that question; it is the same question their own engineers asked when the machine was built.
One bounded trial, with the stop conditions written first
Before a site commits to a whole area, one small, deliberately boring trial is worth more than any number of meetings. Pick one area group - a ramp, or one aisle together with its wheel stops - mark its boundary with tape, and write down before any water moves what would stop the trial: standing water beyond the boundary, a coating lifting, a stain that spreads rather than lifts, a route that cannot be passed with the machine loaded, a battery that dies before the area is finished. Photograph the area first, at an angle that shows the surface texture rather than straight on, and take a second set once the floor has dried. Run the trial exactly as the configuration describes it, battery swap included if one is scheduled. A first pass is not a cycle time; only the second pass gives a figure worth writing down. Inspect the area the next day, after traffic has crossed it, because a car park is judged the following morning, not in the clean window.
The trial answer should be a written record with the same row names as the configuration: mode used, surfaces covered, water actually drawn, time, what stopped, and photographs. If a supplier cannot produce that record, the configuration has no evidence under it.
Handover is a document, not a demonstration
The handover that survives staff turnover is written. It contains the surface list, the mode table with exclusions, the boundary list with owners, the daily route, the trial record, and the named protective features with how each is checked. It names the person who receives it and the date it is next reviewed. A demonstration is a day; a handover document is the reason the machine is still being used two years later. This is also where the exclusions stay visible: surfaces and situations taken out of scope should appear with what replaces them and what that replacement costs in time or water.
What this kind of help does not prove
A configured trial on one area group shows that the arrangement works there. It does not show that the same arrangement works on a differently coated floor, in a warmer basement, on a site with different packs, or on a surface that was never in the trial. It does not carry across to a neighbouring model in the same range; each listing has its own rows, and a feature published on one page is not a feature of the family. Where the cleaning duty sits outside the environment this machine's page describes, the site's own surface list and trial, discussed with an automotive cleaning equipment supplier, decide the question. And where the site needs something no standard listing covers - a different reach, a different mode, a different supply arrangement - that is a customized steam cleaning equipment conversation, which starts with the same written site conditions this article describes.
The short version of a supplier's contribution: they make the split scope visible, they write the configuration against this site's condition rather than against the range, and they leave behind a document that can be checked when the people who arranged it are gone.
