Compared on paper

Specs are the manufacturer’s ratings as listed, collected 1 November 2026. “Not stated” means the listing does not give the figure.

How the points were given

Each washer is scored out of 10 on performance, build, value, safety and warranty, with the weights published on the How We Pick page. Only the two Steupoek listings state an ETL certification, so only those two score on safety. Only the Steupoek listings and one Mutaomay listing state a clear warranty term, so the remaining listings score zero on warranty.

Shop Scores range from a low of 9.2 to a high of 9.8, with each tool positioned by its weighted points proportionally, and more points always yields a higher score.

What the listings tell you

The listings agree on the figures that matter for a washer: maximum PSI, GPM, engine size, hose length and nozzle count, while warranty terms and certifications vary from listing to listing. That variation is why the comparison below separates stated figures from figures a listing leaves out, rather than filling gaps with guesses.

Buying guide: best gas pressure washer under 300

PSI and GPM decide cleaning power

Maximum PSI sets how hard the spray hits a surface, while GPM sets how much water flows each minute. Maximum PSI here runs from 3400 to 4200, and GPM from 2.3 to 4.0, so a pick with a higher PSI figure hits harder and a pick with a higher GPM figure moves more water. For a driveway or a patio, compare both figures together, rather than PSI alone, since a high PSI figure with a low GPM figure still moves less water across the surface.

Nozzles and hose length

A narrow spray concentrates force on a small patch, while a wider spray spreads water for vehicles and siding. Swap nozzles to match the surface, and keep the spray away from people and animals at all times. Hose length matters when the washer stays in one spot: hose lengths here run from 25 ft to 32 ft, so a longer hose reaches around a vehicle without moving the machine.

Engine, fuel and safety

Gas washers run on a small engine, so check the oil level and the fuel before the first job, and run the washer outdoors, never in a closed garage. The Steupoek 4200 32ft washer and both Mutaomay washers list SAE 10W-30 engine oil and 87+ octane gasoline. Wear eye protection when spraying, and never point the spray at people or animals.

Garage Fit Check

• Store the washer with the hose coiled and the nozzles in one place, since every pick here ships with a hose and a nozzle set.
• Leave room to move around a vehicle: hose lengths here run from 25 ft to 32 ft, so the machine can stay put while the wand reaches around.
• Check the oil level before the first job: the Steupoek listings call for an oil check with each use, with 0.2 gallons noted.
• Run a gas washer outdoors, never in a closed garage, and wear eye protection when spraying.
• Match the nozzle to the surface before pulling the trigger, starting with a wider spray on vehicles and siding.

FAQ: garage tools

What PSI and GPM do I need for a driveway?

The picks here list driveway cleaning, with maximum PSI from 3400 to 4200 and GPM from 2.3 to 4.0. Use a wider spray on painted surfaces and a narrower spray on concrete.

Can I use a gas pressure washer on a car?

Yes, with care: all five listings name vehicles or cars among their uses. Use the soap nozzle and a wider spray for paint, and keep the spray away from people and animals.

How long is the hose on these washers?

Hose lengths here are 25 ft on three picks, 26 ft on the VEVOR pick and 32 ft on the Steupoek 4200 32ft pick. A longer hose reaches around a vehicle without moving the machine, while a shorter hose suits a smaller work area.

Do these washers come with a soap tank?

Only the two Steupoek picks list a soap tank, at 1L and 3L. The other picks list a soap nozzle, so check the tank figure for the pick you choose before assuming one is included.

What engine oil and fuel do these washers use?

The Steupoek 4200 32ft washer and both Mutaomay washers list SAE 10W-30 engine oil and 87+ octane gasoline. Follow the manual for the washer you choose.
