The short version: you do not need to spend big to wash a car properly, and after weighing thousands of owner reviews, our #1 pick under $150 is the Sun Joe SPX3000 — owners consistently praise its high flow for the price and how easily it rinses a car and runs a foam cannon. Want a trusted name instead? The Kärcher K1700 and Craftsman CMEPW1700 both sneak under the ceiling, and the Greenworks 1800 is the cheapest way in at around $99. Below is the full ranked field, how we rank, and the honest trade-offs.
The machine is only half the job — flow, technique and a good cannon do the rest. See the full best pressure washer for cars guide, why GPM vs PSI matters more than headline numbers, and the wider pressure washer hub for the rest of the decision.

Electric vs Gas Pressure Washers for Car Washing
Under $150 the whole field is electric, and for car washing that is exactly right. An electric washer starts with a button, runs quietly, needs no fuel or oil, and — crucially — its power sits in the paint-safe range so you cannot easily blast through your clear coat. A gas washer makes far more pressure and never needs an outlet, which is great for concrete and stripping paint off a deck but genuinely risky on car panels, where the extra force can etch or lift paint. For home car-washing duty an electric unit is the safer, simpler and cheaper choice; save gas machines for heavy property work, not detailing.
Other Models Worth Knowing: RYOBI, Kärcher K1800PS and Westinghouse ePX3500
Our ranked field is the value core, but a few adjacent models come up often. RYOBI makes well-liked electric washers, handy if you already own the brand’s batteries and tools. The Kärcher K1800PS is the step-up from the K1700 in this list, adding a bit more flow and an auto start/stop trigger for owners who want the pedigree name with more reach. And the Westinghouse ePX3500 is the bigger sibling of our foam pick, pushing higher numbers for those who wash trucks or want more rinsing headroom. None is necessary to wash a car well — every pick above already does that — but if your budget stretches a little or you have brand loyalty, these are the natural next options.
Portable, Affordable Picks and Where to Get Parts
For a lot of people the appeal of an electric pressure washer under $150 is that it is small, light and easy to store — you carry it out, wash the car, and stand it in a corner of the garage. The most portable units here (the Greenworks and Craftsman) weigh little more than a vacuum and tuck away on a shelf, which matters more than raw power if space is tight. If you want the cheapest possible entry, budget retailers like Harbor Freight sell their own affordable electric washers that wash a car perfectly well, though the long-term review histories are thinner than the names ranked above. One practical tip whatever you buy: check that replacement parts — hoses, O-rings, nozzles and the pump seals — are easy to source for that model, because a $20 hose or seal kit is what keeps an affordable washer running for years instead of becoming landfill after one failure.

How We Rank
We don’t run these washers through a lab and call it a day — a pressure washer lives or dies over years of heat, vibration and thousands of trigger pulls, so we rank by the signal that captures that: aggregated owner ratings, review volume, and the themes owners repeat. We weigh four things. Flow and pressure — enough GPM to rinse a car and PSI that sits safely in the paint window (see GPM vs PSI). Foam compatibility — whether it runs a cannon cleanly, and whether one’s included. Reliability — how the pump and fittings hold up across long-term reviews, not just the unboxing. And value — what you pay versus what you get under a tight $150 ceiling. Prices were current at the time of writing.
The Pressure Washers, Reviewed
1. Sun Joe SPX3000 — Best Overall
The washer the detailing community keeps recommending to newcomers on a budget. Its 2030 PSI and generous 1.76 GPM flow give it real headroom for rinsing, and the dual detergent tanks and long hose make it easy to live with. Owners rate it near the top of the budget field across tens of thousands of reviews. Pros: high flow for the price, long hose and cord, dual tanks, huge positive review base. Cons: plenty of plastic in the fittings, and the pump doesn’t love being run dry.
2. Craftsman CMEPW1700 — Best Value
The sweet spot of trusted-brand and low price. A 1700 PSI / 1.2 GPM unit that sits squarely in the paint-safe window, wrapped in a light, compact body with tidy onboard storage. Pros: name-brand support, easy to move and store, rated highly for reliability. Cons: lower flow than the Sun Joe, and no foam cannon in the box.
3. Kärcher K1700 Cube — Best Trusted Brand
The entry point into Kärcher’s long pedigree. TruPressure 1700 PSI, a back-friendly foot switch, never-flat wheels and a fit-and-finish owners rate a step above the no-name crowd. Pros: trusted build quality, tidy cube design, CETA certified. Cons: priciest here, and the M22 fittings mean you’ll want the right cannon adapter.
4. Westinghouse ePX3100v — Best for Foam
For owners chasing thick suds without a separate purchase. It ships with a detachable foam cannon and a pro-style steel wand, and its 2100 PSI / 1.76 GPM flow lays down a serious blanket. Pros: cannon included, metal wand not plastic, strong flow. Cons: smaller review base than the leaders, and the compact body tips more easily on uneven ground.
5. Greenworks 1800 (1.1 GPM) — Best Budget
The cheapest genuine way onto this list. At around $99 it still delivers a paint-safe 1800 PSI and enough flow to foam and rinse a single car, with a push-button start and a compact, storable body. Pros: lowest price here, simple, PWMA certified, easy to store. Cons: lowest flow at 1.1 GPM, and no cannon or detergent extras.
6. PowRyte Elite (Foam Cannon Kit) — Best Bundle Value
Proof that a budget kit can arrive complete. The PowRyte bundles a foam cannon, four quick-connect tips and onboard storage, and owners keep rating it highly for the sheer value. Pros: most accessories under the ceiling, big positive review base, cannon included. Cons: headline PSI is optimistic marketing — treat the real-world flow as the number that matters, and baby the plastic fittings.
How to Choose a Pressure Washer Under $150
Start with flow, not headline PSI. Any washer here sits in the paint-safe 1,600–2,000 PSI window, so the number that separates them is GPM — flow does the rinsing, and a 1.7 GPM unit clears suds faster than a 1.1 GPM one (the full case is in GPM vs PSI). Next, decide on foam: if you want thick snow-foam out of the box, a kit with a cannon included like the Westinghouse or PowRyte saves a separate purchase; otherwise any of these runs a cannon with the right brand adapter. Then weigh brand support — Kärcher, Craftsman and Sun Joe all back their units and have the review history to prove longevity. Finally, favour washers with a large, long-standing review base; that’s the honest signal a machine survives real ownership, not just the first wash. If you can stretch the budget, the step-up picks are in our best pressure washer under $200 guide.
The Verdict
For the best all-round washer under $150, the Sun Joe SPX3000 is the one owners rate above the rest — high flow, a huge positive review base, and everything you need to foam and rinse a car cleanly. Want a trusted name? The Kärcher K1700 and Craftsman CMEPW1700 both slip under the line, and the Greenworks 1800 is the budget entry at around $99. Check Price on Amazon →
