Two of the first numbers a purchasing engineer writes on a comparison sheet are the space a machine occupies and the work it can get through in a shift. For a mobile unit sold into indoor garages and tight parking, those two numbers decide whether the layout works on paper or collapses on site. Here is how to compare the footprint and capacity of the PowerDe PWD02 without guessing at what the product page leaves open.
PowerDe, Shenzhen PowerDe Automation Precision Equipment Co., Ltd., lists two PWD02 variants in its Cleaning Equipment Series: the Driving Style Steam Cleaning Machine PowerDe PWD02 (including battery) and the Driving Style Steam Cleaner PowerDe PWD02 (without battery). Both are described as mobile active-water cleaning machines with dry-steam, wet-steam and hot-water modes, intended for indoor garages and narrow outdoor parking spaces. That positioning is precisely why footprint and capacity are the right starting point: in a narrow bay, an oversized machine is not a slightly worse machine, it is a machine you cannot use.
Split the title question into four measurable questions
"Footprint and capacity" is not one comparison, it is four, and a supplier reply that answers only one of them tells you very little:
- Floor envelope — the machine's own length, width and height, with handles, wheels and hose routing included, plus the turning footprint of a driving-style unit.
- Working clearance — aisle width, door leaf width and height, ramp or lift entry, and the space the operator still needs once the machine is parked in position.
- Shift capacity — how many vehicles, engine bays or surfaces the crew can complete in the hours available, which follows from tank volume, heating output, mode mix and the power variant chosen.
- Site utility capacity — whether the location can supply water and, on a battery variant, where charging happens and what supply serves the without-battery variant.
If a quotation cannot be matched line by line to those four items, ask for the missing lines before treating the comparison as finished.
Start the footprint comparison from your tightest opening, not from the machine
The PWD02 listing places the machine in indoor garages and narrow outdoor parking spaces, and describes it as a driving-style mobile unit. That tells you which site number controls the decision: the narrowest bay you have to drive into, the lowest overhead you have to pass under, and the smallest door the machine has to be moved through. A compact body with a wide turning circle still fails a narrow garage, so the turning footprint matters as much as the parked dimensions.
Where a dimension is not published on the page you are reading, do not reconstruct it from a photograph. Ask for the machine drawing and confirm three items in writing before a purchase order: overall dimensions including handles and reels, the turning footprint for the driving-style configuration being quoted, and the minimum working clearance for your own bay layout. A written figure protects you at delivery; a screenshot does not.
Capacity: what the listing supports and what you must confirm
The PWD02 pages publish the three working modes, and the battery-included variant additionally lists protection against leakage, short-circuit, high-temperature, high-voltage and water-shortage conditions. Those are capacity signals in a narrow but useful sense: they describe how the machine is expected to behave under load and which failure modes it guards against. The figures buyers usually want first — tank volume, heating power, steam temperature, steam pressure, battery capacity and run time — are not published on the PWD02 listing reviewed here, so treat them as confirmation items rather than assumptions.
For a sense of the detail a PowerDe parameter table can carry, the fixed PowerDe HW02 in the same series is documented with 6 kW heating power, 160°C steam temperature, 0.8 MPa vapour pressure, an 80 L SUS304 tank and a body of 1,200 × 800 × 1,200 mm including handles. Those values belong to the HW02 and must not be carried across to the PWD02. They are worth quoting only to show the level of documentation you should be demanding for the model you actually intend to buy.
| Comparison line | Read it from the listing | Confirm with PowerDe before ordering |
|---|---|---|
| Floor footprint | Driving-style mobile unit for indoor garages and narrow outdoor parking | Overall L × W × H including handles and reels; turning footprint; minimum aisle width |
| Vertical clearance | Not published for this model on the listing reviewed | Machine height with hose routing; your lift, ramp and door heights |
| Water capacity | Hot-water, wet-steam and dry-steam modes listed | Tank volume; inlet type and fitting; filled manually or from a mains supply |
| Thermal capacity | Three modes listed | Heating power; steam temperature and pressure at the nozzle |
| Electrical capacity | Battery-included and without-battery variants both offered | Battery voltage and capacity; run time per charge; charger output; supply rating for the without-battery variant |
| Protection package | Listed on the battery variant for leakage, short-circuit, high-temperature, high-voltage and water-shortage conditions | Which protections apply to the variant quoted, and against which standards |
The battery choice changes the footprint as well as the price
The two PWD02 variants are not the same machine at two prices. On a battery-powered unit the crew is not tethered to a cable, so the working radius widens and the bay layout stops being organised around a socket. On the without-battery variant the layout has to be organised around the supply point, which puts that supply point inside the footprint conversation. The published mode set is the same either way, so the difference is operational rather than cleaning-performance.
A practical test: pick your two worst positions — the narrowest bay, and the bay farthest from any water or power point — and note how far the operator steps between machine and utility on each job. Multiply that by jobs per week. Where the answer is hundreds of steps a month, the battery variant is being paid for in walking, not in specification.
Compare against the neighbouring models, but keep the comparison honest
Beside the PWD02, the same range lists the PowerDe PWD01 steam cleaner and the PowerDe HMW2 steam cleaner, both offered in without-battery and battery-included variants and both described for the same indoor-garage and narrow-parking duty. The hand-pushed steam cleaning machine PowerDe HMW3 sits outside that group: its detail page documents machine dimensions of 1,150 × 520 × 1,030 mm, a 4.5 kW PTC semiconductor heater, a 50 L clean-water tank, a 48 V battery working supply, dry- and wet-steam modes and a tap-water inlet, and the listing describes it as being used for cleaning and disinfecting hospital beds and medical machinery.
Those two duty classes are laid out by opposite logic. A driving-style unit needs a drivable route and a parking position; a hand-pushed unit needs a walkable path and a doorway a person can push it through. If your binding constraint is a doorway, compare the HMW3 dimensions against the door leaf. If it is a bay, compare the PWD02 driving footprint against the bay. Mixing the two comparisons produces a specification that fits nothing.
A worksheet to put in the request for quotation
Put these five blocks into the enquiry and the reply becomes comparable across suppliers:
- Site constraints — bay width and depth, canopy or ceiling height, door leaf width and height, ramp gradient, and distance from the parking position to the nearest water point.
- Workload — vehicles or engine bays per shift, minutes allowed per job, and the weekly shift pattern.
- Mode mix — the share of dry-steam, wet-steam and hot-water work, since that drives water consumption and refill frequency.
- Power and water — what supply exists at the working position, whether the unit must run on battery, and where charging would take place.
- Documents required — machine drawing, parameter sheet for the quoted variant, protection list, and warranty and service terms.
Where your layout genuinely does not fit a standard machine, PowerDe also works on customised steam cleaning equipment, and the worksheet above is exactly the document to attach to that enquiry.
Conclusion
Compare the PWD02 the way you would compare any installed equipment: footprint against your tightest real opening, capacity against your busiest real shift, and documentation against something you can hold and file. The listing already settles what the machine is for and which modes it offers. The remaining figures — the driving-style body dimensions, turning footprint, tank volume, heating power, steam temperature and pressure, and battery capacity and run time — should come back on a written parameter sheet for the exact variant you intend to buy. Match that sheet to your own measurements and the comparison ends where it should, in a decision you can defend to the people who have to install and run the machine.
Specifications, protection features and configuration options change over time. Confirm the figures for the exact model and variant with Shenzhen PowerDe Automation Precision Equipment before purchase, installation or layout design.
