Verdict: Choose a steam cleaner if you detail interiors, upholstery and greasy engine bays and want chemical-free cleaning with little water. Choose a pressure washer if you wash exteriors, wheels and driveways and want the fastest way to blast dirt off paint.
Both clean cars, but they work nothing alike. A steam cleaner loosens grease and grime with hot pressurized vapor and almost no water; a pressure washer blasts it off with cold water at high pressure. This steam cleaner vs pressure washer for cars comparison covers what separates the two sides, then two examples of each from the listings we reviewed.

How each one cleans
A steam cleaner turns tank water into hot pressurized vapor. The CURMEDI makes 239 F steam from 1050W in 3 to 5 minutes; the AULANK makes 229 F steam from 2500W in 10 to 15 seconds with 3 Bar pressure. Steam is water-only cleaning: the AULANK claims 100% chemical-free with no harmful fumes or residue, and the CURMEDI runs on pure water steam. Steam suits interiors, upholstery, grease and tight gaps where water would pool.
A pressure washer moves cold water fast. The CRAFTSMAN pushes 1700 max PSI at 1.2 GPM; the Westinghouse pushes 3000 max PSI at 1.76 max GPM (2600 PSI and 1.1 GPM rated). Both take a mains hose supply and both include soap application: a bottle on the CRAFTSMAN, an onboard 0.45 gallon tank on the Westinghouse. Pressure suits exteriors, wheels, driveways and anything you can rinse.
Steam cleaner vs pressure washer for cars: heat-up and water
Steam needs heat-up time and tank refills. The AULANK heats in 10 to 15 seconds and its 1200 ml tank gives up to 1 hour of continuous steam; the CURMEDI heats in 3 to 5 minutes and its 350 ml tank, 250 ml recommended fill, needs refilling sooner. A figure from one listing describes that listing only: the AULANK’s hour of steam says nothing about the CURMEDI’s runtime. Pressure washers skip heat-up entirely but need a spigot and drain a hose continuously; neither pressure listing states water use per car.
Reach and handling
The pressure washers reach further: a 20 ft hose on the CRAFTSMAN and 25 ft on the Westinghouse, each with a 35 ft cord, and the Westinghouse rolls on 10 in never-flat wheels. The steamers stay close: a 9.4 ft cord on the CURMEDI and a 2 m steam hose plus 1.5 m cord on the AULANK. On weight, the AULANK is 3.8 lb and the CURMEDI 1.76 kg against 17.5 lb for the CRAFTSMAN and 36.8 lb for the Westinghouse. Steam wins on portability; pressure wins on reach.
What each does best
Match the tool to the dirt. Steam dissolves grease and lifts stains from upholstery, carpets and engine bays with little water, and the AULANK’s 6 steam levels tune the output to the surface. Pressure strips mud, road film and loose paint from bodies, wheels and concrete, and the Westinghouse’s 5 nozzles, 0 to turbo, tune the fan to the job. Neither side does the other’s job well: steam will not rinse a muddy truck, and pressure will soak an interior.
Choose a steam cleaner if
- You detail interiors, upholstery and carpets
- You want chemical-free cleaning with little water
- You clean greasy engine bays and tight gaps
- You want the lightest kit: under 4 lb here
Choose a pressure washer if
- You wash exteriors, wheels and driveways
- You want the fastest rinse for mud and road film
- You need soap application built in
- You want the 3-year warranty stated on both washers

Garage Fit Check
- Steam needs only an outlet; pressure needs an outlet plus a spigot and drainage.
- The Westinghouse is 36.8 lb and 22.6 in long; plan floor space, while the steamers store on a shelf.
- The AULANK’s spray gun has no independent switch; steam stops at the main power switch.
- The CURMEDI tank takes 250 ml recommended; overfilling can spray water.
- Both pressure washers state a 3-year limited warranty; neither steamer states one.
Frequently Asked Questions
Can a steam cleaner replace a pressure washer?
Not for exteriors. Steam excels at interiors, grease and upholstery with little water; it will not rinse mud off a truck the way 1700 to 3000 PSI will. Many garages keep both.
Is steam cleaning safe for car interiors?
The listings position steam for interiors, upholstery and car detailing, chemical-free. Keep the nozzle moving, and follow the AULANK’s warning not to direct steam at people, pets or electrical devices.
What PSI do I need for washing a car?
The examples here run 1700 max PSI (CRAFTSMAN) and 3000 max PSI (Westinghouse), both aimed at cars among other jobs. Start with a wide nozzle and keep distance on paint.
Do I need soap with a pressure washer?
Not always, but both examples include it: a soap applicator bottle on the CRAFTSMAN and an onboard 0.45 gallon soap tank on the Westinghouse, which also takes foam cannons with M22 fittings.
How long does a steam cleaner run per fill?
The AULANK claims up to 1 hour of continuous steam from its 1200 ml tank. The CURMEDI’s 350 ml tank, 250 ml recommended, will need refilling sooner; its listing gives no runtime figure.
