A battery pack decides whether a walking or driving job can be finished on one charge, and it decides how much service support you will need a year from now. The PowerDe PWD02 machine is listed in two versions — one supplied with a battery and one supplied without — so the same machine can arrive powered, or arrive as a bare unit for a vehicle that already carries a pack. Either way, the supplier can set the pack up for how your site actually works. The checklist below is what to send before you ask for a configuration, and what to ask them to document in reply.
Start from the site, not the catalogue
Before any battery discussion, write down the places the machine has to reach. The PWD02 is a mobile active-water cleaning machine intended for indoor garages and narrow outdoor parking spaces, and it offers dry steam, wet steam and hot water modes, so the same unit may be asked to work in a low-ceiling basement box, a ramp, a forecourt bay or an outdoor row of spaces. Those are not one environment. A basement box with a floor drain, an outlet on a circuit that also runs lifts, and a short run to the wash point is a different problem from an open parking deck where the nearest outlet is across a driving lane and the ground freezes in winter. Note the distance from the nearest power supply to the farthest vehicle position you clean. That single number tells the supplier whether the machine can run on mains power at all, or whether the battery has to carry it across the site.
What each battery choice changes on site
A supplied battery lets the machine move between positions without hunting for a socket, which matters most where power is scarce, outlets are shared with other equipment, or a cable cannot be run across customer-facing areas. It also means the pack is selected and warranted together with the machine, and a replacement comes from the same party that sold you the unit. A machine supplied without a battery suits a site that fits cleaning equipment onto a vehicle already carrying a pack, or an operator who buys the pack locally to shorten replacement lead times. In that case the supplier sells a bare machine and you own the interface questions: connector type and polarity, charge source, cable routing, and which party answers when a fault appears somewhere between the vehicle's pack and the machine. Settle that ownership question in writing before the order, not at the first breakdown.
Protection settings are not decoration
The battery version of the PWD02 lists leakage, short-circuit, high-temperature, high-voltage and water-shortage protection. Ask the supplier to state, for each protection, three things: what the machine does when the condition is detected (shuts down, limits power, or only warns), how the operator resets it, and which conditions on your site are likely to trip it. A washing bay trips leakage protection if water reaches the enclosure; a ramp in summer tests the high-temperature limit against the pack's working range; a dry run during a shift change is what the water-shortage protection is there for. If the supplier cannot describe the reset path for each protection, the configuration is not finished.
Power quality, charging and cable length
Ask for the charger's input requirements in writing: nominal voltage, current, and whether the machine runs from mains while the pack is charging or charges only when idle. Then check your own supply against those numbers. In covered parking areas the available outlet is often on a shared circuit with lighting, ventilation or lifts, and a socket on a long run can sit far below the machine's working voltage by the time the cable reaches the wash position. Measure the run, or have the supplier state the cable length they recommend and confirm your circuit supports it. The PowerDe cleaning equipment series covers fixed, hand-pushed and driving-style machines, and the difference in power arrangement between them is one of the practical reasons a single catalogue line does not answer a site. Ask for a full dimensioned drawing for the exact variant you are being quoted, not a brochure image.
What the supplier should confirm before quoting
Send the following, and ask for a written answer to each: number of positions cleaned per day; whether cleaning is vehicle exterior, interior or engine compartment work; whether the machine is moved by hand or driven; ceiling height and the width of the narrowest access, including ramps and doorways; distance to the nearest water inlet and the inlet fitting; distance to the nearest power outlet and that outlet's supply; whether the machine stands indoors overnight and at what temperature; and whether you want the pack supplied by PowerDe or fitted by you. Attach two or three photographs of the position where the machine will actually work. A supplier who receives that information can tell you which variant fits and which cannot, and a supplier who does not ask for it is quoting blind.
Battery service life questions to put in the email
Ask, and record the answers: how the pack is charged and what charge equipment is included; whether the pack is user-replaceable or a service-part exchange; what an in-warranty pack claim requires (usage record, storage condition, proof of correct charging); what happens to the machine if the pack is damaged in normal use, such as a struck kerb or a flooded bay; the spare pack lead time from the factory and the price at the time of quotation; and the storage state of charge for a machine parked over a shutdown. These are the points that decide whether a battery version costs more or less than a mains version over a few years. If the answers are vague, the pack is the part of the configuration you have not bought yet.
Ask for a trial on your own floor before the order is fixed
Before you commit, ask the supplier to run the machine on your site, or to document a test that matches your conditions. What you want to see is not a demonstration of cleaning power but the site numbers: how far the unit travels on one charge with the lance in use, whether it clears your ramps and doorways, where the hose can and cannot pass, how long the recharge takes, and where condensed water and runoff end up on your surface. The PWD02 is also listed in a version without battery, so ask the supplier to compare both variants against your site and state why one is recommended. If you are evaluating more than one location, the PowerDe steam cleaning machine range includes driving-style, hand-pushed and fixed units, and customized steam cleaning equipment is available for sites that no standard variant serves.
Contact for a site configuration
Send the site information above to Shenzhen PowerDe Automation Precision Equipment Co., Ltd. — sales@powerde.net, +86 13023198376 — and ask for the variant recommendation, the protection behaviour list, the charger requirements, the pack service terms and the spare-part lead time in one reply. Compare that reply against what your own site can supply, and the choice between a battery version and a battery-free version stops being a catalogue decision.
