Steam Car Washer with Wet and Dry Steam for Mobile and Detailing Work

This steam car washer cleans cars with wet and dry steam and no shampoo. HeyCar builds it in Wuhan.

Each car needs just 2–2.5 L of water.

It produces both wet and dry steam. So one machine handles the outside, the cabin and the engine compartment.

As a result, it suits sites without drainage, mobile crews and detailing shops.

Who this machine is for

• Mobile car wash businesses that work in car parks, offices and homes without drainage.
• Detailing shops that sell interior, engine bay and leather cleaning as separate services.
• Car wash sites that want to add a premium interior service next to an automatic bay.
• Locations with strict water rules where a full wash bay is not possible.

However, a steam machine is a manual tool. For high car volumes, an automatic bay will wash faster.

How the steam car washer works

1. A water pump feeds cold water into a stove or coil.
2. LPG, natural gas or electricity heats the coil.
3. The cold water flashes into high-temperature, high-pressure steam.
4. The operator delivers the steam through the spray gun onto the surface.
5. Insulation cotton keeps the heat inside, so the machine works efficiently.

Then the operator rinses or wipes off the loosened dirt.

Wet steam and dry steam

Wet steam carries more moisture. Therefore, it works well on exterior paint, wheels and lower panels.

Dry steam carries less moisture. So it cleans interiors without damaging water-sensitive parts.

For example, you can use dry steam on leather seats, the air conditioner and the gearbox area.

In addition, high-temperature steam gives a sterilising, antibacterial effect inside the cabin.

Site and installation requirements

The machine weighs 65 kg, so a small team can move it between work areas.

It runs on 220V / 380V. Therefore, confirm which voltage you need when you request a quote.

Before quoting, answer these questions:

• Which voltage do you have on site or in your service van?
• Will you heat with LPG, natural gas or electricity?
• Do you work at a fixed shop or as a mobile crew?
• Which services will you sell, such as interior, engine bay or full exterior?

Because it uses so little water, you do not need a drainage system for most jobs.

Running costs per car

Water use stays at just 2–2.5 L per car. Plus, you need no shampoo.

Your main running costs are fuel or electricity for heating, and operator time.

Meanwhile, you can charge separately for each area, such as the interior, engine bay and seats.

As a result, one car can bring several service fees instead of one wash price.

Honest limits

• Steam cleaning is manual work, so each car takes more operator time than an automatic bay.
• Very heavy mud may need a pre-rinse before steam cleaning.
• Gas heating needs safe fuel storage and trained operators.
