Dry-steam cleaning is the mode buyers ask about most often, yet the applications listed for it differ from one machine to another. On the PowerDe cleaning equipment page, every model states whether it offers dry steam alongside wet steam and hot water, and each product description names the work that mode is meant for. This article goes through the product page model by model, so you can match the mode to your site before you request a quotation.
Where the dry-steam mode appears on the product page
The Cleaning Equipment Series lists ten machines. Six of them — the PWD02, PWD01 and HMW2 driving-style units, each sold in a battery and a battery-free version — are described as mobile active-water cleaning machines with three cleaning modes: dry steam, wet steam and hot water. The remaining four units — the hand-pushed HMW3 pair and the fixed HW03 and HW02 — switch between two methods, dry steam and wet steam. Dry steam therefore appears on all ten listed models; what changes is how much heat and pressure sits behind it, and which jobs the description attaches to it.
Vehicles in tight parking areas: PWD02, PWD01 and HMW2
For the driving-style machines, the page names hot water and steam cleaning machine duty in indoor garages and in the narrow spaces of outdoor parking lots. The machine drives itself, so an operator can stop, position and drive it again without dragging a heavy cabinet across a floor. The PWD02 example we looked at carries a 4.5 kW semiconductor heater, a 60 L clean-water tank fed from a tap, a high-pressure water gun with nozzle, and a vacuum cleaner with a flat nozzle for the interior. That combination suits forecourts and covered parking where a fixed unit cannot reach, and where the steam pass is followed by a hot-water rinse.
The battery-included and battery-free versions of each model are the same machine in this respect. Choose the battery-free version when a 220 V supply is available where you work, and the battery version when you need to move away from the wall. The page also lists leakage, short-circuit, high-temperature, high-voltage, water-shortage and high-voltage-explosion protection on these units, which matters when a machine runs unattended for a heating cycle in a public parking area.
Medical rooms: HMW3 and the fixed 220 V units
For the hand-pushed steam cleaning machine line, the applications on the page are cleaning and disinfecting hospital beds and medical machinery. The hand-pushed model runs on a 48 V battery with a 4.5 kW PTC heater and a 50 L clean-water tank, in a footprint of 1150 × 520 × 1030 mm — small enough to push through a ward doorway and park beside a bed frame. Dry steam is the useful mode here: it carries heat into a surface with very little free water, so the surroundings stay dry enough for the room to come back into service.
The fixed HW03 is described the same way — hospital beds and medical machinery — with a 220 V supply instead of a battery, which fits a laundries or central-decontamination room where the machine stays in one place. If your workload is a fixed room with a known power point, the fixed unit is the simpler choice; if cleaners move between floors or buildings, the battery-driven hand-pushed version saves the cable work.
Service stations and engine bays: the fixed HW02
The product page gives the Fixed Steam Cleaning Machine PowerDe HW02 the most specific list of dry-steam applications of any model on the page: cleaning vehicle exteriors at gas stations and parking lots, vacuuming and disinfecting the interior, and cleaning the engine compartment. Its specification table backs that up with a 6 kW heating power, steam temperature of 160°, vapor pressure of 0.8 MPa, an 80 L SUS304 tank, and a 220 V working voltage, with a vacuum cleaner supplied alongside the dry and wet steam modes. The cabinet measures 1200 × 800 × 1200 mm including handles and takes tap water through a 4-point internal-tooth joint (1/2 inch).
Those figures explain why this model is put forward for engine compartments rather than bodywork alone. A dry-steam pass at 160° and 0.8 MPa lifts hardened oil and road grime off engine covers and bay walls, and the low water volume keeps the rinse light around electrical parts. For a forecourt operator, the practical benefit is that the same machine covers the exterior wash, the interior vacuum and the bay clean, so you staff one process instead of three.
Reading the page before you order
A few rules of thumb follow directly from what the product page states. If your job is a surface that must dry quickly — a ward, an elevator car, a lobby floor beside a trading area — pick a model whose description pairs dry steam with the work, and check the steam temperature and pressure rather than the heating power alone. If your job is caked grease on an engine bay or a chassis, look for the higher-pressure unit and use dry steam to loosen, then wet steam or hot water to flush. If your work moves between parking bays or between buildings, choose a battery version so the steam pass is not interrupted by cable changes.
The product page does not publish steam temperature and pressure for the mobile and hand-pushed models, so treat those two lines as the first question in your enquiry, together with the water tank size and the supply voltage at your site. The intelligent cleaning equipment manufacturer behind the series also offers customized configurations and engineering services, so a specification that does not match your workflow can be reviewed rather than accepted as-is. Send your site conditions — floor area, power availability, the surfaces you clean and the cycle you need to hold — and the matching model and mode can be confirmed against the same data the product page publishes.
