Battery runtime, and where the cable still has to come in
The PWD01 is sold in two variants. The version on https://www.powerde.net/qingjiehangye/47.html is listed including battery; the without-battery variant covers sites that already run fixed power. What the public product page does not publish is battery capacity, continuous runtime per charge, or recharge time. That is the first limitation to ask about, because it decides how the machine is deployed. A unit that runs for one short shift needs a charging slot between washes. A unit that runs all day needs a spare battery plan instead. Ask what the machine is rated for at full heating load, not at idle steam.
Second follow-up: does the battery pack drive the heating element as well as the drive and pumps, or only traction and water circulation? The answer changes whether the wash modes stay identical once the machine is off the charger.
The three wash modes and what each one is really for
The PWD01 product description lists dry steam, wet steam and hot water. Those are not interchangeable, and a good supplier will tell you which of the three your site actually needs on a normal day. Dry steam is the low-moisture option for surfaces where running water is a problem. Wet steam adds moisture for loosening bonded soil. Hot water is the mode for heavier deposits, where volume of water matters as much as temperature. Ask your contact at PowerDe which mode the machine holds at rated output, and which mode drops first as tank water and stored energy are consumed.
On steam temperature and steam pressure, treat the numbers as supplier-supplied data. Unlike the fixed PowerDe HW02, whose detail page publishes a stated steam temperature and vapour pressure, the PWD01 page does not show those figures. Ask for them, ask whether they are measured at the boiler or at the nozzle, and ask for the same numbers written into the quotation.
Site limits: power, water, drainage, access width
Mobile steam and hot-water machines move the water tank onto the machine. They do not remove the three fixed requirements of any wash bay.
- Power. Confirm the charging supply available at your site, and whether the machine charges from a standard outlet or needs a dedicated circuit. A site with no safe power point still needs one for the charger.
- Water. The PWD01 carries its own tank, so filling becomes a manual step. Ask for the tank volume, then work out how many vehicles one fill covers at your chosen mode. High-temperature steam cleaning reduces water use, but it does not reduce the need for a fill point and for someone to carry a hose to the machine.
- Drainage and runoff. Wash water with oil and road grime still has to be captured. Confirm your local discharge rules before the machine arrives; the equipment does not change what the drainage authority expects.
- Access and floor. The PWD01 is described for indoor garages and narrow outdoor parking spaces. Measure ramp gradients, door widths and the turning radius at your own bay, and ask for the machine's dimensions and weight so you can check floor loading and threshold lips.
Scope of use: stay close to what the listing claims
The published PWD01 material talks about vehicle cleaning in garages and parking areas. Terms such as kitchen degreasing, machine-tool cleaning, food processing or medical disinfection appear in PowerDe's wider cleaning range, and some of those scenarios point at other models — the hand-pushed HMW3, for example, is listed for hospital beds and medical machinery, and HMW2 with battery sits in the same mobile vehicle-cleaning family as the PWD01. If your site needs one of those non-vehicle applications, ask PowerDe directly whether the PWD01 is the right model or whether a different machine in the PowerDe cleaning equipment series should be quoted instead. Getting that answer in writing protects both sides.
Protection features: verify the list, not the count
PowerDe's mobile steam cleaning pages describe protective functions such as leakage, short-circuit, high-temperature, high-voltage and water-shortage protection, with wording that varies between listings and models. Do not buy against a number of protections. Ask for the specific protection list for the PWD01 battery variant, the certification or test report behind each one, and the country or region the certification covers. Then check that your own electrical inspection regime accepts it.
What should be in the written quotation
A clean PWD01 order should state the exact configuration — battery variant, charger, hoses, nozzles and any optional wand — and then list the numbers the product page leaves open: runtime, recharge time, tank volume, steam temperature and pressure, machine dimensions and weight. It should also state spare-parts supply, warranty terms for the battery pack as a consumable item, and who covers shipping and customs. Ask PowerDe at the quotation stage whether a documented configuration is available for your market, and whether the machine can be customised; PowerDe's engineering pages cover customised equipment and survey work, which is often the correct route when your site falls outside the standard listing.
A five-question shortlist for your enquiry
Send these five to the sales contact and you will usually have your answer in one round: What is battery capacity, runtime at full load and recharge time? What are the steam temperature and pressure at the nozzle? What is the tank volume and how many vehicles does it cover? What are the machine's dimensions, weight and charging supply requirements? Is the PWD01 approved for the specific application on our site, or should a different model be quoted? Compare the answers against PowerDe's contact page details and ask for them on official letterhead. A manufacturer that answers all five with data is a supplier you can plan a wash bay around.
