Dry-steam mode appears on almost every steam-cleaning listing, because it is the mode buyers associate with cleaning that uses very little water. What product pages do not do equally well is explain the mode in numbers. Some pages publish a full parameter table; others name the mode and stop. This article reviews what the PowerDe cleaning-equipment listings currently state about dry-steam cleaning mode, model by model, and separates the values you can read from the page from the values you still need to request in writing.
Where dry-steam mode appears in the listings
All ten product entries in the Cleaning Equipment Series category mention dry-steam mode. They cover six models, and the way the mode is described differs by machine type:
- Two-mode machines that switch between dry steam and wet steam: the Fixed Steam Cleaning Machine PowerDe HW02, the Fixed Steam Cleaning Machine PowerDe HW03, and the Hand Pushed Steam Cleaning Machine PowerDe HMW3.
- Three-mode ride-on machines that add a hot-water mode: the PowerDe PWD02, PWD01 and HMW2 driving-style machines, each listed in including-battery and without-battery variants.
The two groups are positioned for different jobs. The two-mode pages describe vehicle cleaning at gas stations and parking lots, or the cleaning and disinfection of hospital beds and medical machinery. The three-mode pages describe indoor garages and narrow outdoor parking spaces. A mode name on a product card is a description of what the machine can do, not a specification of how well it does it.
The listing that specifies dry steam with numbers
One entry — the Fixed Steam Cleaning Machine PowerDe HW02 — is the only listing reviewed here whose detail page publishes the parameters behind the dry/wet steam switching:
- Steam temperature 160 °C and vapor pressure 0.8 MPa
- Heating power 6 kW
- 80 L tank made of SUS304 stainless steel
- Working voltage 220 V, with a tap-water inlet (4-point internal-tooth fitting, 1/2 inch)
- Machine size 1,200 × 800 × 1,200 mm, including handles
- A vacuum cleaner in addition to the dry/wet steam function
- Protection functions listed on the page: leakage, short-circuit, high-temperature, high-voltage, water-shortage and high-voltage-explosion protection
These lines describe one system, and they should be read that way. Steam temperature and vapor pressure are two readings of the same saturated steam: at a given pressure, the temperature follows. Heating power decides how quickly the machine recovers steam between trigger pulls, which sets how long an operator can work before waiting. Tank size sets the work cycle between refills. The HW02 page also states its uses directly — vehicle exterior cleaning at gas stations and parking lots, interior vacuuming and disinfection, and engine-compartment cleaning — which is worth noting when you compare it against pages that only name a mode.
What the other listings state, and where the table stops
The hand-pushed HMW3
The hand-pushed steam cleaning machine PowerDe HMW3 is described as a high-temperature, high-pressure machine with dry and wet steam modes, listed for cleaning and disinfecting hospital beds and medical machinery. Its detail page publishes a partial table: a 4.5 kW PTC semiconductor heater, a 50 L clean-water tank, a tap-water inlet with a 4-point internal-tooth fitting, 48 V battery power, machine dimensions of L1150 × W520 × H1030 mm, and a high-pressure water gun with nozzle.
What the page does not publish is exactly what a dry-steam comparison needs: steam temperature and pressure, battery capacity and runtime, charger output, weight, hose and wand lengths, and the accessory list. If dry-steam performance on medical or other hard surfaces matters to your decision, temperature and pressure are the first two values to request in writing.
The driving-style PWD01, PWD02 and HMW2
The three driving-style listings name dry steam, wet steam and hot water as selectable modes and describe use in indoor garages and narrow outdoor parking spaces. The driving style steam cleaner PWD02 page and the HMW2 pages also mention leakage, short-circuit, high-temperature, high-voltage and water-shortage protection. None of the three pages publishes steam temperature, steam pressure or hot-water temperature.
Each of these models appears twice, as an including-battery variant and a without-battery variant, and the two pages carry the same specification table — the difference between them is who supplies the battery. What actually ships with the machine, such as the charger and accessories, is therefore a written confirmation item before ordering, not something the listing settles.
The fixed HW03
The category listing for the PowerDe HW03 describes a 220 V high-temperature, high-pressure machine with dry and wet steam modes for hospital beds and medical machinery. One caution before you quote this model in your own documents: the overview text on the page appears to call it “PowerDeHMW3 (220V)”, so confirm the model designation with the manufacturer before putting it into a specification sheet or a purchase order.
What no listing answers about dry-steam mode
Even the fullest product card leaves operational questions open. Before you compare two machines on dry steam, send each supplier the same short list and compare the written answers:
- Steam temperature and pressure for any model whose page omits them — currently the HMW3, HW03, PWD01, PWD02 and HMW2 listings.
- How the mode is selected on the machine, and how long steam recovery between trigger pulls takes.
- Steam output per hour, which determines how much area one operator can cover in a shift.
- Which hose, wand and nozzle options are supplied for dry-steam work, and their lengths.
- Battery capacity, runtime and charger output for the battery-powered models.
- Water consumption and refill frequency for the stated tank size.
These are ordinary specification questions. A supplier who answers them in writing can be compared; a supplier who repeats the marketing copy cannot.
A reading order for comparing listings
If you are shortlisting machines from product pages alone, work through the listings in this order:
- Separate machines that name the mode from machines that specify it. At present, only the HW02 page publishes the steam temperature and pressure behind the mode.
- Read every parameter table as a set. Temperature, pressure, heating power and tank size describe one system; a single large number means little on its own.
- Match the stated use to yours. Vehicle cleaning at a parking lot, medical machinery cleaning and garage work differ in access, power supply, drainage and safety conditions.
- Treat every unpublished value as an open item, and put it in a written request before the shortlist closes.
- Arrange a trial on your own surfaces, with the mode set as the datasheet describes, before any purchase decision.
If a value you need is not on the page, request it from PowerDe through the contact page. A written specification is the only fair basis for comparing dry-steam performance.
