A quotation for a mobile steam cleaning machine usually arrives with a model name and a short feature list. Before the purchase order, the operator still has to translate that page into site conditions: what the machine can produce, what the building can supply, and what has to be proven on a trial. The checklist below is the one a facility team can work through with the supplier in the room.
Start with the figures printed on the product page
Read the parameter table, not the marketing paragraph. On PowerDe's fixed PowerDe HW02 steam cleaner page the table states 6 kW heating power, a 160° steam temperature, 0.8 Mpa vapour pressure, an 80 L SUS304 tank, a footprint of 1,200 × 800 × 1,200 mm including handles, and a 220 V working voltage. Mobile units carry their own tables; the driving-style PowerDe PWD01 steam cleaner pages present it as a mobile active-water machine with dry-steam, wet-steam and hot-water modes for indoor garages and narrow outdoor parking spaces, in variants listed with and without a battery.
Write each figure down as something to verify for your own installation, not as a guarantee. The PowerDe site is not always consistent across pages, and a value that matters for your plant or forecourt should be confirmed in writing with the manufacturer before it drives your layout.
Match the utility supply before the machine arrives
Three supplies decide whether a position is usable at all. First, electrical: the HW02 table reads 220 V and 6 kW, so the socket, cable run and protection at that position must actually deliver it; a driving-style unit that works from a battery changes the question, but it does not remove the need to plan charging and storage. Second, water: the fixed machine lists a tap-water inlet with a 4-point internal-tooth joint, 1/2 inch, so the thread and the supply have to exist at the working point, not across the yard. Third, drainage: wet-steam and hot-water modes leave runoff, and the floor needs a fall, a drain and a way to keep that runoff away from customer areas and walking routes.
Walk the working area, not just the floor plan
A mobile unit is only mobile through the space you have. Measure the aisle widths, gate openings, turning radius, ramps and the height clearance at the entry, then compare them with the dimensions in the table. For the fixed HW02 the listed envelope includes handles, which is exactly the detail that is easy to miss when someone quotes a width. Then check surface-to-surface distance: where the unit must be parked, where the operator stands, and how far the hose or wand has to reach. If the machine cannot be moved to the task, the specification is irrelevant.
Ventilation and bystander separation belong in the same walk. Steam at the temperatures printed in these tables is a burn hazard to the operator and to anyone who walks past, so mark a working boundary, plan the hours when the area is empty, and treat a hose crossing an aisle as a trip and contact hazard that needs routing or protection.
Confirm mode and control needs against the task
List the surfaces you intend to clean and decide which mode each one needs. Dry steam suits surfaces where you must limit moisture; wet steam and hot water suit heavier soil; a vacuum function, where a machine lists one, is a separate capability for interiors and should be read from that machine's own page rather than assumed. The driving style steam cleaner pages for the PWD02 variant, for example, add a vacuum-suction row that other models in the same area do not show, so a feature that exists on one page cannot be transferred to another. Where the task sits outside the cleaning area described on the product page, raise it with the supplier as customized steam cleaning equipment instead of assuming fit.
Run a compatibility trial on a hidden area first
Choose one sample surface your buyer cares about, such as a painted panel edge, a gasket, an electrical enclosure, a coated floor, or a timber or composite element, and apply the mode you plan to use on an inconspicuous area. Record the distance held, the pass, the result, and anything that lifted, discoloured, softened or allowed water in. Keep that record and have the supplier sign off on it. This trial is also where you test the practical things the table cannot tell you: how long the unit runs before it needs water or charging, how the fittings connect under your own water pressure, and how one operator handles the wand and the cable at the same time.
Read the protection list as functions, not as a number
PowerDe's cleaning pages describe protective functions such as leakage, short-circuit, high-temperature and water-shortage protection. Ask what each one actually stops, how the operator knows it has triggered, and how it is reset, and be clear that these functions do not cover someone pointing the wand at a colleague, a fitting used beyond its rating, or a machine cleaned into an area it was never meant to reach. Where the wording of the protection list differs between pages, take the item list from the page you were quoted and have the supplier confirm it, rather than counting the items yourself.
Plan the training and the paperwork you will be asked for
Before go-live, name who is allowed to run the machine, who supervises, and what a new starter must demonstrate. Ask the supplier what instruction material ships with the unit, in which language, and whether on-site commissioning or refresher training is available. Keep a simple written procedure at the machine: start-up checks, the working boundary, the shutdown sequence, and what to do if a protection trips or a fitting leaks.
What to put to the supplier before signing
Take the checklist to the supplier as a set of written questions: confirmed supply requirements for the exact model and variant; the footprint including handles and hose; the water inlet fitting you have on site; which modes and functions that variant actually has; how the protections are verified; spare-parts availability and who services the unit; delivery, commissioning and training terms. An intelligent cleaning equipment manufacturer that answers these in writing gives you a document to work from; answers that stay in a phone call leave the risk with you.
If you want a site-specific answer rather than a catalogue page, send PowerDe your floor layout, the surfaces you clean, and the trial record from your sample area at sales@powerde.net or +86 13023198376, and ask them to confirm the model, the supply requirements and the scope in writing.
