A fixed steam cleaning machine is installed at one location and expected to work a full shift, every day, at a gas station, a parking facility, a fleet depot or a detailing shop. Unlike a portable unit, it becomes part of your workflow, so a wrong choice shows up as downtime and lost revenue rather than a minor inconvenience. Before you request a quote, get clear answers to the questions below.
What power and water supply does the machine require?
Ask the supplier exactly what the machine needs on site: working voltage, heating power, and whether it connects directly to tap water. A 6 kW heater on a 220 V circuit draws far more current than ordinary shop equipment, and an under-sized circuit will trip breakers during busy hours. The PowerDe HW02 runs on 220 V with 6 kW heating power and takes a tap-water inlet, which avoids a separate water-treatment setup at most sites. Confirm your circuit capacity and water connection before the machine ships, not after installation.
What steam temperature and pressure does it actually deliver?
Ask for measured steam temperature and vapor pressure instead of marketing adjectives. Temperature is what breaks the bond between grease and metal; pressure is what pushes steam into seams, wheel arches and engine crevices. The HW02 delivers steam at 160° with 0.8 MPa vapor pressure. Write those numbers down and compare them against your own tasks, such as engine-compartment degreasing or stubborn road film on vehicle exteriors, so you are comparing capability rather than brochures.
Can it switch between dry steam and wet steam?
Different jobs call for different moisture levels. Dry steam carries little moisture, suits engine-bay degreasing and surface disinfection without soaking the area, while wet steam softens caked-on dirt before wiping. Ask whether mode switching is built into the machine or requires changing attachments. The HW02 switches between dry and wet steam and also supports a vacuum cleaner for interior vacuuming and disinfection, so exterior bodywork, interiors and engine compartments can be handled at one workstation.
How large is the water tank, and what is it made of?
Tank capacity decides how many vehicles you can clean before refilling, and tank material decides how long the machine survives hard water and daily use. The HW02 carries an 80 L tank made of SUS304 stainless steel. When comparing offers, ask what tank and boiler material the other machine uses and how descaling is handled. That answer, more than the price tag, determines your long-term maintenance cost.
What safety protections are built in?
A steam machine combines high temperature, high pressure, electricity and water inside one cabinet, so the protection circuits matter as much as the cleaning performance. Ask what happens when the tank runs low, the temperature overshoots, or the machine develops a leak. The HW02 lists leakage, short-circuit, high-temperature, high-voltage and water-shortage protection. Get the supplier to explain how each protection behaves in practice and how the machine is reset after it trips.
Will it fit the space you actually have?
Fixed machines are heavy and stay where you put them. Ask for the full external dimensions, including handles and hose routing. The HW02 measures 1,200 × 800 × 1,200 mm including handles. Measure your bay, check door widths, and plan drainage and hose reach before delivery. A machine that cannot pass the doorway or reach the far side of the washing bay wastes floor space you are already paying for.
What support comes after delivery?
Ask about warranty terms, spare-parts availability, operator training, and whether the manufacturer can adjust configurations for your market. PowerDe presents itself as an intelligent cleaning equipment manufacturer with customization and technical support behind its equipment, so serious buyers can discuss configuration changes instead of accepting a fixed catalog specification.
A shortlist checklist for your next quote
- Working voltage, heating power and water inlet requirements, checked against your site

- Dry and wet steam modes, and how you switch between them
- Tank capacity and material, plus the descaling plan
- Protection functions and how the machine resets after a trip
- Full dimensions, doorway widths, drainage and hose reach
- Warranty, spare parts and training commitments in writing
If one candidate meets the checklist, examine the details on the product page for the PowerDe HW02 steam cleaner, or review the full range of PowerDe cleaning equipment and contact the team with your site conditions before requesting a configuration.
