The PowerDe PWD01 driving-style steam cleaning machine is listed on our site in two versions, and the one without an onboard battery is easy to misread. The product page for the PowerDe PWD01 without battery shows a complete specification table, yet the battery line reads "Customer provided batteries". For a procurement team comparing quotes, that combination raises a fair question: is the machine fully specified, or is an essential part of it still undefined? This article walks through exactly what the published page commits to, what it deliberately leaves open, and which documents to request so the specification can be verified line by line before you place an order.
Start from the product page, not from a datasheet PDF
Every PowerDe cleaning model in the Cleaning Equipment Series has a permanent product page, and that page is the primary reference for verification. For the PWD01 without battery it is divided into four blocks you can check independently: an overview of the machine and its safety design, a "characteristic" image gallery, a specification table, and a pair of links to the related variants. Nothing in the overview is a marketing adjective that cannot be traced to the table below it, which is exactly what you want when a spec sheet later has to match a contract.
A practical first step is to save a dated copy of the page. Equipment listings are revised, and a printed snapshot of the table you were quoted against removes most later disputes about what was published at the time of enquiry.
What the published table actually states
The specification table on the PWD01 (without battery) page publishes the following items, and these are the figures you can hold the supplier to:
- Machine dimensions: L2500 mm × W900 mm × H1050 mm, noted under "Automatic movement".
- Mode of movement: autonomous driving, which is what the "driving style" description refers to.
- Heating power: 4.5 kW, using a PTC semiconductor heater.
- Tank volume: 80 L clean water tank.
- Water inlet: tap water supply with a 4-point internal-tooth joint.
- Cleaning modes: hot water, dry steam and wet steam.
- Working voltage: 48 V mobile battery system, with batteries supplied by the customer.
- Cleaning method: high pressure water gun with nozzle.
- Vacuum method: vacuum cleaner with a flat nozzle, discharging to a sewage tank.
The overview adds a second layer that is easy to overlook because it is written as prose rather than as a row in a table. It states that the machine uses leakage protection, short circuit protection, high temperature protection, high voltage protection, water shortage protection and high voltage explosion-proof design. Treat each named protection as a separate item on your verification list, because each one corresponds to a component you can ask to see or to a test you can ask for.
The table also carries two model identifiers that matter for paperwork: the brand line reads "PowerDe cleaning machine" and the model line reads PowerDe PWD01 with "Battery not included", manufactured by Shenzhen PowerDe Automation Precision Equipment Co., Ltd in Shenzhen. When you request a quotation or an invoice, check that the model string on the document matches the model string on the page you verified. The most common confusion on this product line is not a wrong number, it is a wrong variant — a battery-inclusive quotation reviewed against a battery-free page, or the reverse.
The line that changes the whole calculation: the battery
The battery row is the row that determines your total cost and your site layout. The PWD01 without battery is sold on the basis of a 48 V mobile battery system that you source locally, which is a reasonable arrangement when local battery freight, customs handling or after-sales support is simpler for you than shipping a battery from the factory. It does mean that four numbers the product page does not publish have to come from your own battery supplier instead: battery capacity in amp-hours, expected runtime at working load, charger output and charge time, and the physical weight and footprint of the battery you install.
Add those four to the published 4.5 kW heating power and the 80 L water tank and you get the real operating picture: the battery must carry a 4.5 kW heating load as well as the drive and pump functions, and the battery you choose sets how long a shift runs before charging. Write both specifications — machine and battery — on one sheet before comparing offers, otherwise two quotations that look identical on the machine will differ by the battery alone.
If you would rather receive the machine ready to run, the same series lists the PWD01 with battery included. Comparing those two pages side by side is a quick way to see which items the factory supplies and which items you are expected to supply, and it removes any ambiguity about what the delivery price covers.
Documents to request, and what each one proves
Verification is not one document; it is a short set of documents that cross-check the table. Ask for these when you enquire, and match each against a specific row:
- A signed specification confirmation that repeats the published rows — dimensions, heating power, tank volume, cleaning modes, working voltage — and states the model variant explicitly.
- Electrical drawings or a wiring outline for the 48 V DC input, showing the connector type, polarity, fuse or protection rating, and the accepted battery voltage window. This is the document your electrician needs before the battery is even purchased.
- Component declarations for the heater and the protection devices named on the page, so the PTC semiconductor heater and the leakage, short circuit, high temperature, high voltage, water shortage and explosion-proof protections can be traced to identifiable parts rather than to a sentence.
- A packing list and accessory list for the water gun, nozzles, hoses and the vacuum kit with the flat nozzle, since these are listed as part of the cleaning method but are not itemised on the page.
- An inspection or commissioning record from your own factory acceptance test, covering a cold-water flow check, a steam-mode check on both dry and wet steam, a hot-water mode check, and a simulated trip of each protection function.
Items not published on the page should be recorded as a question, never filled in from assumption. Steam temperature and delivery pressure for the PWD01, battery capacity and runtime, charger specification, machine weight, hose and wand lengths, noise level and water consumption per hour are not on this product page, and they belong in the specification confirmation rather than in your own estimate. Our engineering team can supply them in writing on request, and a written figure protects both sides.
Fit for the space: checking the footprint before the machine arrives
The published dimensions — 2500 mm long, 900 mm wide, 1050 mm high — are the numbers to test against your site, not just against the product page. This machine is described as being intended for indoor garages and narrow outdoor parking spaces, and it is designed to be driven rather than pushed, so the relevant check is whether it can reach the work area and be parked there. Walk the route with those three measurements: gate and doorway clear widths, turning radius at the entrance, ramp gradients, the height limit of any covered area, and the location of the tap water connection with the matching 4-point internal-tooth joint. Confirm that a 48 V battery charging point can be placed at the parking position as well.
This site check is also where the water and drainage details become concrete. The page specifies a tap water inlet and a sewage tank for the vacuum function, so you need a water point at the working position and a route to dispose of the recovered water in line with your site's drainage rules. Both are cheap to plan around and expensive to retrofit.
Where PowerDe supports customised cleaning equipment
Not every site matches a catalogue configuration. Where the published PWD01 specification does not fit your workflow — a different tank arrangement, a specific battery standard you are required to use, or a tank volume that has to match your water supply — our Solutions pages cover customised cleaning equipment and OEM or ODM development, and the engineering service pages cover hardware testing for validation before series delivery. For a buyer, that means the specification conversation does not stop at "this is the published sheet"; it continues into configuration and testing, and the resulting documents become part of your order file.
A six-step verification routine for buyers
- Print the product page for the exact variant, with the date, and quote against that printout.
- Confirm the model string on every document matches "PWD01 (Battery not included)".
- Request the missing numbers — steam temperature and pressure, weight, accessory list, hose and wand lengths — in writing.
- Agree the 48 V battery interface: connector, protection rating, accepted voltage window and charger location.
- Check the 2500 × 900 × 1050 mm footprint and water and drainage points on site.
- Define the acceptance test before the order is placed, not after delivery.
The PWD01 without battery is fully documented on the rows the manufacturer owns, and deliberately open on the rows the customer owns. Once those two sets are separated on paper, the specification is verifiable and the quotation comparison is straightforward.
To confirm the missing parameters for your project or to request a written specification for a specific configuration, contact our team at sales@powerde.net or +86 13023198376, and we will send the documents listed above against the exact model you are evaluating.
