This guide compares the portable washers on what each listing states: pressure, batteries, nozzles, hose and foam, so you can match the washer to the cars you wash.

Compared on paper

Every rating comes from the brand’s listing and is not a shop test (gathered 11 November 2026). Where a listing contradicts itself, both figures are shown.

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 method page. Only one washer here carries a stated safety listing, so the rest score zero on safety. Two listings are title only, with no bullets and no spec table, so they sit last in the ranking.

No score drops under 9.2 or climbs past 9.8; a tool’s place inside those bounds is set by its weighted point total.

What the listings tell you

Only one of the washers here is corded, the Westinghouse, and the rest run on batteries. Two listings state 600 PSI, one states 2100 max PSI and one states 870 PSI. Two listings state a foam bottler, one states a detachable foam cannon and one states a foam bottle. The Westinghouse is the only washer here with a stated warranty term, 3 years of limited service, labor and parts coverage.

Buying guide: the best portable car pressure washer with foam gun for driveway washes

PSI for paint

Pressure is the first split here. The Westinghouse is rated at 1800 PSI and 1.2 GPM, with up to 2100 PSI and 1.76 GPM at the extremes, The two MYPIN washers state 600 PSI and no GPM, and the RITHRY states 870 PSI and no GPM, so no cleaning units figure can be worked out for them. The Adnexum states no PSI at all. Use the wide nozzle on paint, keep the wand moving, and wear eye protection.

Batteries and runtime

Two washers here run on 21V batteries: the MYPIN 3.0Ah pack states 45 minutes from two 3.0Ah batteries, and the MYPIN 2.0Ah pack states 60 minutes from two 2.0Ah batteries. The Adnexum states two rechargeable batteries with no capacity stated, and the RITHRY states battery operation with no capacity stated. The Westinghouse is a corded electric washer, so it runs as long as the job takes, with no battery to charge.

Foam cannon and foam bottle

Foam is the point of this guide, and the listings cover it three ways. The Westinghouse has a detachable foam cannon to add detergents for heavy duty cleaning. The two MYPIN washers include a foam bottler, and the Adnexum includes a foam bottle. The RITHRY states no foam accessory, so it is the only washer here without one.

Nozzles

The two MYPIN washers and the Adnexum use a 6-in-1 nozzle with six modes, 0°, 15°, 25°, 40° and two more that differ by listing: mist mode and shower mode on the 3.0Ah pack, straight mode and shower mode on the 2.0Ah pack. The 3.0Ah pack adds 2 jet nozzles for smaller angles. The Westinghouse has a 3-nozzle set with a pro-style steel wand. The RITHRY states no nozzle list.

Hose and water source

The MYPIN 3.0Ah and the RITHRY state a 5M hose, and the Westinghouse states a 20 ft hose. The MYPIN hoses end in a filter that keeps impurities out of the sprayer gun, per the listings. The MYPIN 2.0Ah and the Adnexum state no hose length. Check the hose length against the distance from your tap to the car before you order.

Garage Fit Check

• Store the cordless washers with their batteries charged: two batteries each, 3.0Ah on one MYPIN and 2.0Ah on the other.
• The Westinghouse is the only corded washer here; the rest run on 21V batteries or a stated 1500W motor.
• Check the hose: 5M on the MYPIN 3.0Ah and the RITHRY, and 20 ft on the Westinghouse.
• Keep the foam bottle and nozzles with the washer so the kit stays together.
• The MYPIN listings warn to keep hands and people away from the water spout.

FAQ: garage tools

How do I clean a car with a pressure washer?

Start with foam over the whole car, let it sit, then rinse with the wide nozzle and keep the wand moving. The Westinghouse foam cannon and the MYPIN foam bottlers are made for this. Wear eye protection, and never point the spray at people.

How much water does it take to wash a car with a pressure washer?

The Westinghouse states 1.2 rated GPM. The cordless washers state no GPM, so no water figure can be worked out for them. The 5M hose on two washers here runs from a nearby tap to the car.

How do I use car shampoo in a pressure washer?

Use the foam accessory the washer includes. The Westinghouse has a detachable foam cannon to add detergents, and the two MYPIN washers include a foam bottler. The Adnexum includes a foam bottle. The RITHRY states no foam accessory.

Can I clean a car engine with a pressure washer?

None of the listings here mention engine cleaning. The washers here are listed for cars, fences, driveways, floors, gardens and patios. Check the manual for your washer before you aim it at an engine bay.

What size pressure washer do I need for a car?

The washers here state 600 PSI, 870 PSI and 1800 rated PSI. The 600 PSI cordless washers suit light washing with foam, and the Westinghouse at 1800 rated PSI suits cars plus driveways and fences. Pick the pressure that matches the jobs around your home.
