1. The power supply at your bays, stated in numbers
A battery version is chosen for run time; a mains version is chosen for continuous duty where supply exists. So start with your own data: available voltage at each wash position, the rating of the circuit and its protection device, and the distance between them. Then ask PowerDe for the matching figures for the exact unit being quoted — supply voltage and heater power. For reference, the fixed 220V steam cleaning machine PowerDe HW02 is listed at 220 V with 6 kW heating power, which shows the order of magnitude a steam generator demands. Ask specifically about the first heating phase from cold: that is when a steam machine draws hardest, and it is the moment a marginal circuit reveals itself.
2. Working radius, set by the cable rather than by the battery
With no battery, the mains cable is the limit of movement. Confirm the cable length as delivered and whether a trailing socket or extension arrangement is included, specified by PowerDe, or left to you. In a long parking row or a garage with one supply point, this determines whether the machine can serve every position from one socket or whether additional outlets must be installed. Put the measured distance from the supply point to the farthest wash position in your enquiry and ask for confirmation that the delivered cable arrangement covers it.
3. A packing list for the no-battery configuration
Ask for a line-by-line packing list for the PWD02 without battery, stating explicitly that no battery and no charger are supplied unless they are. The list should name the hose and wand, nozzles, the gun, the control components, brushes, and any vacuum accessory, and mark which of these are standard and which are optional. The same list should appear on the shipping documents, so the packing you receive can be checked against the packing you paid for.
4. Water: connection, capacity and quality
Ask for the tank volume and the inlet fitting, including thread type and size. PowerDe's published parameters for the fixed series describe a tap-water inlet with a 4-point internal-tooth fitting and an 80 L SUS304 tank on the HW02, so request the equivalent figures for the PWD02 and confirm whether an adapter is included for your water point. Ask what happens when supply pressure is low or the tank empties during a job. Then discuss water quality: scale is the failure mode that shortens the life of heating elements and steam lines, and the treatment recommended for hard-water sites is a specification item, not an afterthought once the machine is running.
5. Output matched to the soil you remove
Request published figures for steam temperature and steam pressure, and for hot-water mode, then compare them against your actual work. The HW02 page lists 160° steam temperature and 0.8 MPa vapor pressure with dry and wet steam switching, and describes vehicle exterior cleaning at gas stations and parking lots, interior work and engine-compartment cleaning. Road film on bodywork, engine-bay deposits and workshop grease are three different tasks, and an operator working on all three needs to know which mode and which nozzle combination PowerDe specifies for each. Ask what automotive cleaning equipment accessories and cleaning agents are recommended, and which ones are not.
6. Protection functions and the documents that prove them
PowerDe's product pages list leakage, short-circuit, high-temperature, high-voltage and water-shortage protection, with high-voltage-explosion protection on some models. Ask which of these are fitted on the PWD02 without battery and request the documentation that your site may need for sign-off: wiring diagram, description of each protection function, and a user manual in the language your operators read. If your company keeps an equipment safety file or requires an electrical inspection before commissioning, request those documents while the order is still being quoted.
7. Fit to a narrow garage or parking space
The PWD02 is described as a driving-style machine for exactly these confined settings. Ask for overall dimensions and the clearance needed to drive and park the unit between jobs, and check those figures against your bay layout, not against a brochure photo. Send photographs or a simple layout drawing showing supply points, drainage and the width of the working lane. PowerDe presents itself as an intelligent cleaning equipment manufacturer with customized configurations and technical support among its capabilities, so an access problem raised at the quotation stage can be engineered around instead of discovered on installation day.
8. Consumables, spares and the support route
Ask which parts wear in normal service — seals, hoses, nozzles, filters, gun components — and request a recommended spares list with prices so that stock can be ordered with the machine. Then set out the fault route: who you contact, in which language and time zone, how a diagnosis is made remotely, and which repairs are handled by shipped parts versus returned units. Steam machines are used daily in paid washing work, so downtime is a cost, and the support route belongs in the purchase decision.
9. Warranty written for the machine you are actually buying
Get the warranty terms for the no-battery configuration, not a generic sheet: start date, what is covered (heater, pump, control system, frame), what is excluded (wear items, misuse, scale damage), and what voids cover. The last point matters for a mains unit in particular, since an unapproved supply arrangement, extension or water feed can be treated as misuse. Read the exclusions against how your staff will actually use the machine.
10. Delivery, acceptance test and repeat units
Agree the packaging and transport terms, the wording that identifies the no-battery variant on documents, and a short acceptance test at arrival: cold-start power-on and heater warm-up on your own circuit, dry steam, wet steam, hot water, and a check of each protection function. Write the agreed figures on the test sheet and keep it. If you are equipping several bays, ask PowerDe to keep the specification identical across units, so one spares list, one manual and one training routine cover the whole set.
What to send PowerDe in the first message
Include your supply voltage and circuit rating at each bay, the distance the cable has to cover, the packing list you expect without battery, the tank volume and inlet fitting you need, the temperature and pressure figures for your soil type, the protection functions and documents required for sign-off, your bay dimensions and lane width, the spares list you want priced, the warranty terms for this configuration, and the acceptance test you will run. Shenzhen PowerDe Automation Precision Equipment lists customized steam cleaning equipment among its services, so the more site detail that reaches the engineering team first, the fewer specification rounds the order needs.
The no-battery PWD02 suits operators who wash close to a dependable supply and want continuous duty without battery management. It suits no one whose circuits are marginal or whose washing distance is undocumented. Settle these ten points in writing, and the choice becomes a calculation about your site rather than a guess about the machine.
Send your bay layout, supply data and cleaning duty to the PowerDe team at https://www.powerde.net/contact/ and have the specification confirmed before the order is placed.
