PowerDe lists the PWD02 driving-style cleaning machine twice: one listing is PowerDe PWD02 steam cleaner (including battery), the other is PowerDe PWD02 (without battery). The two product pages carry the same description and the same specification table, so the choice is not about cleaning performance. It is about who supplies the mobile battery pack, and what that means for commissioning, spares and day-to-day care of the machine. This article compares the two configurations using only what the two pages publish, and lists the questions to settle with the manufacturer before you order.
What the two PWD02 pages have in common
Read the specification tables side by side and they are identical. Both listings describe an autonomous-driving mobile unit for indoor garages and narrow outdoor parking areas, with the same frame size, the same heating unit and the same water capacity:
- Machine dimensions L1275 mm × W570 mm × H1185 mm, with autonomous driving as the mode of movement
- 4.5 kW heating power using a PTC semiconductor heater
- 60 L clean water tank, tap-water inlet with a 4-point internal thread joint
- Three cleaning modes: hot water, dry steam and wet steam, applied through a high-pressure water gun with nozzle
- Vacuum cleaner with a flat nozzle connected to a sewage tank
- The same set of protective functions: leakage, short-circuit, high-temperature, high-voltage, water-shortage and high-voltage explosion-proof protection
The working-voltage row reads “220V (455V Mobile Battery)” on both pages, with the remark “replaceable”. In other words, the machine runs on a 455 V mobile battery pack, and the pack is a separate, replaceable item in both configurations. The cleaning result you get on a vehicle or a garage floor is fixed by the heater, the tank, the modes and the nozzle — none of which change between the two listings.
What actually differs between the two configurations
The difference is confined to the battery supply. Neither page states a battery capacity, an amp-hour figure, a runtime per charge, a charger output or a pack part number, so the practical distinction has to be read from what the listings do say:
- Including battery: the 455 V mobile pack is supplied with the machine. The pack arrives matched to the machine’s connector and charging arrangement, and it ships and is commissioned as one unit.
- Without battery: the machine is delivered as the same unit with the battery omitted. You source a pack that matches the voltage, connector and physical mounting the machine expects, and you handle its charger and storage yourself.
- Unchanged in both: cleaning modes, heating power, tank volume, water inlet, dimensions, vacuum equipment and the protective functions listed above.
Because the machine body is the same, a buyer who chooses the battery-excluded version is not buying a lesser hot water and steam cleaning machine. They are taking on the battery procurement task instead of leaving it to the factory.
How the battery decision plays out on site
Commissioning and lead time
With the pack included, commissioning is a matter of charging the pack, checking the water inlet and drain route, and training the operator on mode selection. With the pack excluded, the machine can sit unpacked while you confirm that a locally sourced pack matches 455 V, the machine’s connector and its mounting position. Ask the factory to state the connector type and the charger output in writing before you commit to a third-party pack; a pack that is electrically close but mechanically different will delay the installation.
Working cycles and spare packs
The pages describe a machine that “can be stopped and driven at any time”, which is useful in a shared garage lane, but they do not publish how long one charge supports. Until you have that figure in writing, plan the working day around the water tank rather than the battery: a 60 L clean-water tank sets a refill point you can measure on your own site, and timing one full vehicle wash tells you how many cycles you can complete before refilling. If your operation runs two shifts, ask whether a second pack can be swapped during a break and how long the swap takes — the “replaceable” remark suggests the pack is meant to come out, but the method and time are not documented.
Idle periods and storage
A cleaning machine in a car-wash bay or a fleet depot may be used daily for part of the year and lightly for the rest. A pack that stays with the machine and is charged on a regular cycle behaves differently from a pack stored separately over a quiet season. Whichever configuration you choose, ask for the storage and re-charge guidance for the pack, and keep it with the machine’s operating instructions so the same rules are followed by every operator.
Which configuration fits your situation
Two honest tests usually settle it:
- Choose the battery-included listing if you want the machine ready to work on delivery day, if you have no existing process for buying and maintaining traction battery packs, or if one responsible operator will use the machine every day in a fixed indoor bay with a charging point.
- Consider the battery-excluded listing if you already buy and service battery packs for other mobile equipment and can match the 455 V requirement and connector yourself, or if you want to compare pack suppliers and spare-pack pricing on your own terms.
If you are also weighing the fixed installations in the same range, the site requirements are different: a fixed unit needs a dedicated power circuit, a water inlet and a drain route at one position, while a driving-style unit moves between bays. Comparing the two on your own floor plan, rather than on the specification sheet alone, avoids buying mobility you cannot use.
Questions to settle with the manufacturer before ordering
The two product pages stop short of the battery details a buyer needs. Send this short list with your enquiry and you will get comparable answers for both configurations:
- Battery capacity and the expected number of vehicle washes or minutes of operation per charge, measured on the machine.
- Charger output, charge time, and whether the charger is included in either configuration.
- The connector type, mounting position and weight of the pack, so a locally sourced pack can be checked before purchase.
- Whether a flat pack can be changed by the operator mid-shift, how long that takes, and whether a spare pack is available as a spare part.
- Warranty terms for the pack, and storage or re-charge guidance for periods when the machine is not in use.
- How the pack is shipped, and whether it travels with the machine in the same crate.
Written answers to these six points turn the two listings into a straightforward commercial comparison. If you need them before committing, contact PowerDe with your bay layout and the vehicles you clean, and ask for the battery details alongside the machine specification.
In short
The battery-included and battery-excluded PWD02 configurations clean the same way, because the machine body, heater, tank, modes and protective functions are identical on both product pages. The decision comes down to who supplies and maintains the 455 V pack. Buy the pack with the machine when you want a single point of supply and a fast commissioning; take the machine without it when you already have a battery purchasing and servicing process and want to control that part yourself. Either way, get the runtime, charger and connector details in writing before you order.
