EGO Power+ HPW3204 Review: The First Cordless Pressure Washer With Real Muscle

The EGO Power+ HPW3204 ranks fourth on our Best Pressure Washers list with a 9.0, and it earns that spot for doing something no cordless pressure washer had done convincingly before: hitting a pressure number you can actually use for more than detailing a car. Buy it if you already own EGO's 56V Arc Lithium batteries from a mower, blower, or chainsaw — the interchangeability across that platform is the real economic argument here. Skip it if you're starting from zero and just want the cheapest legitimate pressure washer, because the corded Greenworks Pro GPW3001 gets you there without an additional battery purchase.

What it actually is

Cordless pressure washers have historically been a compromise category — genuinely portable, but capped well below the pressure that makes a machine useful for real cleaning jobs rather than light touch-ups. The HPW3204 is EGO's attempt to close that gap, and the number that matters is 3,200 PSI at 2.0 GPM, running off a pair of EGO's 56V Arc Lithium batteries. That's a peak rating, which is true of most pressure washer specs, but the more telling figure is what happens under sustained trigger load: pressure holds consistently above 2,800 PSI, well ahead of the 2,030 PSI budget-tier Sun Joe SPX3000 and within real striking distance of the 3,000 PSI corded Greenworks Pro GPW3001.

The battery story is where the actual evaluation happens. Two 5.0 Ah 56V batteries deliver roughly 20 to 25 minutes of continuous trigger time — enough for a car wash, a deck, or a single bay of a driveway, but not a full property in one charge. EGO's Arc Lithium platform recharges in about 60 minutes per battery on the rapid charger, so owning two charged pairs effectively covers a full afternoon of work without standing around waiting on the charger.

In use

Pro Tool Reviews put the practical case plainly: "the HPW3204 delivers enough pressure to strip grime off concrete, clean a deck before sealing, or blast oxidation off vinyl siding — the cordless solution for people who need to clean where an outlet is not convenient." That's the specific use case this machine solves that a corded electric can't: anywhere without a nearby outlet, or anywhere running an extension cord is genuinely inconvenient, this is the pressure washer that still gets real cleaning done.

Reviewed's assessment gets at why that matters more than the spec sheet alone suggests: "the first battery-powered pressure washer that earns its PSI rating under sustained trigger time rather than as a peak-spec marketing claim." Cordless tools have a well-earned reputation for headline numbers that collapse under real load, and the fact that independent testing found the HPW3204's pressure holding up during actual use — not just at the moment the trigger is pulled — is the detail that separates this from earlier cordless pressure washer attempts.

The real evaluation, though, is economic rather than technical. For a buyer already invested in EGO's outdoor-power-equipment lineup — mowers, blowers, chainsaws, all sharing the same 56V battery platform — the HPW3204 effectively costs only the tool head, since the expensive part of any battery-powered outdoor tool is the batteries themselves. For a buyer starting from zero, the $549 sticker price undersells the real cost: you're also paying $200-plus for batteries just to make the tool functional, on top of a weight penalty — 38 pounds with batteries installed, heavier than most corded electrics in this category.

Strengths

• The first cordless pressure washer that earns its PSI rating under real trigger load. Sustained pressure above 2,800 PSI, not just a peak number that evaporates the moment you start cleaning.
• Battery interchangeability across the entire EGO outdoor platform. If you already own EGO mowers, blowers, or chainsaws, this pressure washer effectively costs only the tool head.
• Genuine cordless freedom for jobs away from an outlet. No cord-radius limit, no extension-cord voltage-drop concerns — a real advantage for detached structures, boats, or properties without convenient power access.
• A brushless direct-drive motor that avoids belt-driven slippage, delivering cleaner power transfer than some other cordless pressure washer designs on the market.

The trade-offs — who should skip it

• The runtime ceiling is real. Twenty to 25 minutes per battery pair is enough for a car, a deck, or a single driveway bay — not a full property in one session. Plan around it, or budget for a second battery pair.
• New buyers are paying for batteries they don't yet own. At $549 for the tool alone, a buyer with no existing EGO batteries needs an additional $200-plus investment just to run this machine — a cost the corded competition doesn't carry.
• It's heavy for the category. At 38 pounds with batteries installed, this weighs more than most corded electric pressure washers, a real consideration if you're moving it around a property repeatedly during a cleaning session.

How it compares

The clearest comparison on its own list is the Greenworks Pro GPW3001 at rank one, the corded electric that this machine's cordless freedom is directly traded against. The Greenworks hits 3,000 PSI at 2.0 GPM through a brushless induction motor with no cord-radius limit beyond the 35-foot hose itself, and it costs $100 less at $450, with nothing extra required to run it. The honest trade is straightforward: pay less and get instant readiness with a cord to manage, or spend more on the EGO platform and get true cordless freedom with a real runtime ceiling and, for new buyers, a hidden battery cost on top of the higher sticker price.

Further up the durability spectrum, the Simpson ALH3425 at rank two is the gas cross-shop for buyers who need continuous-duty performance neither this nor the Greenworks is built for — a Honda GX200 commercial engine and triplex pump rated for hours of concrete-cleaning work, at nearly double the HPW3204's price and with the fuel and maintenance that come with any gas machine.

The Gavler verdict

A 9.0, reflecting genuine credit for being the first cordless pressure washer to hit a usable pressure number under real load, tempered by the honest economics of battery-platform buy-in. This is the right pick for existing EGO 56V Arc Lithium owners, where the tool effectively costs only the $549 head unit and the pressure genuinely holds up during actual cleaning. It is the wrong pick for a new buyer who just wants the cheapest legitimate pressure washer with no strings attached — for that buyer, the corded Greenworks Pro GPW3001 gets to the same cleaning result without an additional battery purchase standing between the sticker price and actually using the machine.

Common Questions

Is the EGO Power+ HPW3204 worth it in 2026?

Yes, but mainly for one specific buyer: someone who already owns EGO 56V Arc Lithium batteries from mowers, blowers, or chainsaws. It ranks fourth on Gavler's Best Pressure Washers list with a 9.0, and it earns that spot as the first cordless pressure washer to hit a pressure number under real trigger load — roughly 2,800 PSI sustained against a 3,200 PSI peak rating. Buyers with no existing EGO batteries are paying for a tool that needs 200-plus dollars of additional batteries to actually run.

How long does the EGO Power+ HPW3204 run on a charge?

Roughly 20 to 25 minutes of continuous trigger time on a pair of 5.0 Ah 56V batteries — enough for a car wash, a deck, or a single bay of a driveway, but not a full property in one charge. Each battery recharges in about 60 minutes on EGO's rapid charger, so owning two charged pairs effectively covers a full afternoon of work without waiting on the charger mid-job.

EGO Power+ HPW3204 or Greenworks Pro GPW3001 — which should I buy?

Buy the Greenworks unless you're already invested in the EGO 56V battery platform. The corded Greenworks Pro GPW3001 costs about 100 dollars less at 450 versus 549 — and the real gap is bigger than the sticker prices suggest, because the Greenworks is ready to run out of the box with no separate battery purchase, while the EGO needs batteries you either already own or have to buy on top of the 549 dollar tool price. If you own EGO mowers or blowers already, the battery interchangeability makes the HPW3204 effectively cheaper than its sticker price.

Does the EGO HPW3204 actually hit 3,200 PSI, or is that just a peak spec?

It's a peak number, but it holds up better than most cordless peak claims under actual use. Trigger-time pressure under load lands consistently above 2,800 PSI, which is meaningfully ahead of the 2,030 PSI budget-tier Sun Joe SPX3000 and within real striking distance of the 3,000 PSI corded Greenworks Pro GPW3001 — a genuine result for a battery-powered machine, not a marketing-only figure.
