Start with the numbers PowerDe publishes for both variants
PowerDe lists the PWD01 (without battery) as a driving-style active water cleaning machine, and the PWD02 (without battery) as the same family in a more compact body. Both entries describe dry steam, wet steam and hot water modes for indoor garages and the narrow spaces between parking bays, and both are driven machines rather than hand-pushed units. Before comparing anything else, open the PowerDe PWD01 steam cleaner page and the PWD02 page side by side, and write down the machine dimensions and box volume from each specification table.
| Specification item | PWD01 (without battery) | PWD02 (without battery) |
|---|---|---|
| Machine dimensions | L2500 mm × W900 mm × H1050 mm | L1275 mm × W570 mm × H1185 mm |
| Box volume (clean water tank) | 80 L | 60 L |
| Mode of movement | Driving style, automatic movement | Driving style, automatic movement |
| Heating power | 4.5 kW (semiconductor heating) | 4.5 kW (semiconductor heating) |
| Cleaning modes | Hot water, dry steam, wet steam | Hot water, dry steam, wet steam |
| Working voltage as listed | 48 V mobile battery, customer provided | 220 V (455 V mobile battery), replaceable |
| Cleaning / vacuum method | High pressure water gun with nozzle; vacuum cleaner with flat nozzle, sewage tank | High pressure water gun with nozzle; vacuum cleaner with flat nozzle, sewage tank |
Read the table as a snapshot of one product page, not as a specification sheet. The voltage line is the clearest example of why: the PWD01 page states 48 V mobile battery with the batteries supplied by the customer, while the PWD02 page shows 220 V together with a 455 V mobile battery marked replaceable. Ask PowerDe to confirm, in writing, which supply arrangement applies to the unit you are quoting, because battery choice changes weight, run time, charging space and service plan.
Footprint: compare the envelope against your real layout, not against a catalogue claim
The footprint gap is the headline. The PWD01 measures L2500 × W900 mm, so it needs more than twice the length and about 50 percent more width than the PWD02 at L1275 × W570 mm, while the PWD02 stands roughly 135 mm taller. Height rarely blocks a cleaning machine unless it must pass a low door, a mezzanine or a car lift; length and width are the constraints that decide whether a machine can work in your building.
Do not accept a machine on the strength of the two numbers alone. Measure four things with a tape in the place where the machine will actually operate:
- The narrowest aisle between parked vehicles, plus any door or gate the machine has to pass. Leave a working margin around the listed width instead of fitting it exactly.
- The turning path. A longer body swings wider when reversing between bays, and the published dimensions do not tell you the turning radius or how the machine steers under load.
- The floor route from the fill point to the wash area. Both models take tap water through a 4-point internal-tooth joint, so a quick-connect fitting and hose run belong in the layout as much as the machine itself.
- Storage and charging space for the batteries, if you buy the variant that carries them.
Then put the machine on the floor for a trial. Ask PowerDe for the turning radius, the total weight with a full tank, and the floor loading figures, and check that your surface, drainage channel and ramp can carry the loaded unit. A machine that fits on paper but cannot reverse into your bay is the wrong machine.
Capacity: tank volume drives your working rhythm
Clean water tank volume is the number that sets how often an operator stops. The PWD01 carries 80 L, the PWD02 60 L, both listed as box volume for a clean water tank. Neither page publishes water consumption per hour, so the honest way to size capacity is to measure it yourself during a trial.
Run one full tank on a job that matches your routine and record four numbers: how many vehicles or how many square metres the tank covers in each of the three modes; how many fill and drain stops one shift needs; where the fill point and the drain point sit relative to the work area; and how long a hot-water run takes compared with a dry-steam run on the same surface. Multiply those results by your daily volume, and the 20 L difference between the two models either becomes the reason to choose the larger tank or becomes irrelevant because a fill stop costs a couple of minutes in your layout.
Also read capacity together with the cleaning and vacuum set-up. Both pages list a high pressure water gun with nozzle and a vacuum cleaner with a flat nozzle tied to a sewage tank. Confirm the hose and wand lengths, the accessory list and the sewage tank volume, since none of those items appear in the tables above and they shape the daily workflow as much as the clean water tank does.
Match the model to the site, and treat the modes as a shared baseline
Both models offer hot water, dry steam and wet steam, both use a PTC semiconductor heater, and both pages list leakage, short-circuit, high-temperature, high-voltage and water-shortage protection alongside high-voltage explosion protection. In other words, mode range and safety design do not separate the two machines. Footprint and tank volume do.
A practical rule of thumb: where the wash area is a wide bay, a fleet depot or an indoor garage with room to manoeuvre, the longer PWD01 and its larger tank reduce fill stops and let one operator cover more ground. Where the machine has to thread between parked cars in a narrow outdoor lot or a tight indoor garage, the shorter and narrower PWD02 usually wins even with the smaller tank, because manoeuvring time, not tank size, sets the pace.
Keep the wider product family in view while you compare. If your site also needs a fixed unit at a service station or a parking facility, PowerDe cleaning equipment covers driving-style, hand-pushed and fixed steam cleaning machines, so you can quote a mobile machine for the lot and a stationary one for the bay in a single enquiry.
What to put in your enquiry before you choose
Send PowerDe the same short brief for both models and you will get comparable answers instead of marketing text:
- A sketch or photo of your wash area with the measured aisle width, door height and turning space marked.
- Your daily volume: number of vehicles or surfaces, shift pattern, and which cleaning mode you expect to use most.
- Your power situation on site, and whether you already hold 48 V battery packs or would run the unit on mains supply.
- A request for the unpublished figures: weight with a full tank, turning radius, hose and wand lengths, accessory list, noise level and water consumption per hour for each mode.
- A written confirmation of which battery and voltage configuration applies to the quoted machine.
Once those items are in writing, the comparison becomes simple: pick the footprint that fits your measured layout, then confirm that the matching tank volume keeps fill stops inside the time your operators can afford. That is how a buyer compares the footprint and capacity of the PowerDe PWD01 without battery against the rest of the driving-style range without relying on catalogue slogans.
