1. What is being cleaned, and what is on it
The first confirmation is not about the machine at all. Ask what the target surface is made of, what the deposit consists of, how thick it usually is, and whether the surface carries electrical parts, bearings, seals, wiring, insulation or coatings that must stay dry. A gasoline engine compartment, a stainless-steel hood above a stove, a painted vehicle panel and a machine-tool guideway all respond differently to the same steam output. Write these details down for each application area rather than treating "vehicles" or "kitchen" as one single duty.
2. What steam condition the application actually needs
Steam output has to be described on two separate axes. First, dryness: a drier steam carries more heat into a deposit and leaves less free water behind, which matters on electrical and instrumented surfaces; a wetter steam rinses loosened soil as it works. Second, the settings the machine offers. PowerDe lists both dry-steam and wet-steam modes across the cleaning range, and the driving-style models additionally add a hot-water mode, which is why hot water and steam cleaning machine options are specified separately from steam-only units. A new application should state which of these modes will be used most, because that choice drives the model selection more than the price does.
Published temperature and pressure figures describe the machine at its rated condition, not the steam arriving at the surface. The HW02 detail page, for example, lists a 160° steam temperature and 0.8 MPa vapor pressure; how those values translate to a specific nozzle, hose length and working distance is something to confirm with the manufacturer for your duty, not to assume. Where a supplier publishes a single headline number with no context, treat it as incomplete information rather than as an answer.
3. What the site can supply: power, water, drainage, access
This is where most new-application plans stall, so confirm it before the quotation is requested.
- Electrical supply. The fixed units in the range are specified for 220 V working voltage, and the HW02 listing states 6 kW of heating power. Check the available supply, socket type and circuit capacity at the exact position where the machine will stand — not at the distribution board across the yard. Battery-powered machines answer a different question: they remove the cable run, but they add charging space and runtime limits to the plan.
- Water source and water quality. The HW02 page specifies a tap-water inlet with a 4-point internal-tooth joint (1/2 inch) and an 80 L SUS304 tank. Confirm hose length, pressure, and whether the site water is hard enough to justify a treatment step; scale behaviour is a maintenance question that starts at the specification stage.
- Drainage and run-off. Steam loosens the deposit; the residue still has to go somewhere. For food areas, vehicle bays and machine shops, identify the drain, any oil separator, and whether run-off is allowed at all.
- Access and footprint. The HW02 detail page gives overall dimensions of 1,200 × 800 × 1,200 mm including handles. Walk the route from the parking or storage point to the work face with those dimensions in mind, and note door widths, ramps, steps and turning space. This is the reason the range is split into fixed, hand-pushed and driving-style formats: the narrow garage or parking layout pushes toward the driving-style machines, while a fixed installation suits a permanent bay.
4. Duty cycle, workload and staffing
State the real workload: how many units are cleaned per shift, how many minutes each one takes, how many shifts per day, and whether the work is continuous or burst. That number decides whether one machine with a rechargeable battery covers the shift or whether a mains-powered unit, a spare battery, or two machines are needed. It also decides the tank size and heating capacity you should be asking about. Ask the same question about labour: a machine that saves cleaning solvent but adds an operator minute per vehicle may not be the saving everyone expected.
5. Protection, safety and operator conditions
For the mobile and fixed models, the product pages describe leakage, short-circuit, high-temperature, high-voltage and water-shortage protection; some pages repeat the high-voltage item in a different wording, so count the protection functions on your own quotation rather than relying on a count quoted from memory. Confirm which protections apply to the exact variant you are buying, and match them to your site's safety rules — wet floors, hot surfaces, working near live electrical equipment, and confined vehicle bays all call for written procedures and training. A machine is only as safe as the method statement around it.
6. What the trial should prove, and what the quotation must include
Before ordering, run one controlled trial on a real surface with real deposits, and agree the pass criteria in advance: deposit removed, no damage to the substrate, acceptable time per unit, acceptable run-off handling. Put the model variant, the modes to be supplied, the accessories, the warranty terms, spare-parts supply and the delivery lead time in the same written request. If the standard catalogue machine does not fit, PowerDe lists customised configurations and engineering services, and an OEM or ODM enquiry for customised steam cleaning equipment is the route for a purpose-built bay rather than a reconfigured catalogue unit.
A short confirmation checklist
Before any specification is signed off, confirm six items in writing: the surface and the deposit; the steam mode required; the site's power, water, drainage and access limits; the shift workload and the staffing model; the protection functions and the safety procedure; and the trial pass criteria with the full quotation scope. Those six answers let a supplier recommend a model instead of guessing one.
Shenzhen PowerDe Automation Precision Equipment lists both a cleaning-equipment range and engineering services on its site, and its cleaning pages carry model-level parameters that can be checked against your own site survey. Send your application details, photographs of the surface and the deposit, and the site's power and water information, and the specification conversation starts from facts instead of assumptions.
