DeWalt 2X20V MAX 1600 MAX PSI 1.2 GPM Brushless Cordless Pressure Washer Kit

First impressions and setup

I rolled this DeWalt cordless washer out of its box, snapped in the hose and wand, and was cleaning within minutes. It’s a compact, cart-style unit with on-board storage for the hose, wand, and nozzles, plus a foam cannon that tucks away neatly. The design favors portability: 24 pounds is easy to manage, and not having a cord or gas engine to fuss with makes a bigger difference than I expected. DeWalt includes a 25-foot high-pressure hose, a 10-foot suction hose, and four quick-connect tips (turbo, 15°, 25°, 40°). The three-speed control keeps things simple, and Boost mode is there when you need more bite.

Build quality is what I want from a jobsite-capable tool: solid plastics, tight fittings, and a brushless motor that spins up smoothly. The axial cam pump isn’t exotic, but it’s quiet and consistent. The FLEXVOLT batteries seat securely and the whole package feels ready to be tossed in the truck without babying it.

Performance: what 1,600 PSI and 1.2 GPM gets you

This washer is tuned for real-world household tasks, not blasting concrete spall off a driveway. At up to 1,600 MAX PSI and 1.2 GPM, it shines on vehicles, patio furniture, vinyl siding, grills, windows, and general cleanup. With the 25° tip on medium, I cut through pollen and road film on two vehicles quickly, then used the 15° on Boost to tackle wheel wells and bug-splattered mirrors. On vinyl siding with light mildew, the turbo nozzle on low/medium speed was the most efficient: the rotating jet adds mechanical agitation without chewing up battery too fast.

On patio pavers with embedded algae, I could lift the film with multiple passes, but this is where the limits show. You can freshen the surface; you won’t erase years of oil stains or deeply stained concrete at this pressure and flow. A large driveway or deck stripping job will be slow going. If that’s your primary use, a higher-output corded electric or a gas unit is the better fit.

Flow matters as much as pressure, and the 1.2 GPM here is enough to move debris without making a muddy mess. Rinses are controlled, overspray is modest, and you’re less likely to carve wood grain or scar soft materials. For most homeowners, that’s a feature rather than a bug.

Battery life and runtime

Cordless pressure washing only works if the batteries keep up. With the two included FLEXVOLT 12.0 Ah packs, I routinely got about 50 minutes of mixed-use runtime (mostly low/medium speeds, with short stints on Boost and some turbo nozzle work). Dedicated Boost-heavy sessions trimmed that to around 35–45 minutes. Letting the tool work—using the right tip and slower passes—extends battery life noticeably.

Two chargers in the box is a smart touch. If you plan longer sessions, you can top both packs simultaneously while you take a break, and the large-capacity packs pull double-duty in other FLEXVOLT tools. Weight-wise, the big packs don’t upset balance. The unit stays planted when you tug the hose, and the cart handle gives you a handy grab point when you need to reposition.

Self-priming from a bucket or tank

The self-priming intake is a standout feature. Using the 10-foot suction hose and the included filter, I drew from a 5-gallon bucket and a portable water tank. Keep the water level near the pump intake height or higher, keep the hose straight, and open the trigger for a few seconds—priming takes place quickly. Once primed, flow remains steady. This makes the washer genuinely useful away from a spigot: I cleaned a trailer at a storage lot and rinsed mud off tools on a jobsite without hunting for a faucet.

A few tips:
- Only use fresh water to protect the pump.
- Keep the filter submerged and clean.
- Expect a slight hit to runtime versus a pressurized garden hose source, but not enough to be a dealbreaker.

Foam cannon and detailing

The integrated foam cannon is better than the throw-ins I usually ignore. Fill it with a proper soap at the recommended dilution, and it lays down a dense, clinging layer that actually helps loosen grime. It’s not as tuneable as a high-end aftermarket lance, but for cars, trucks, and siding detergent application, it’s fast and effective. Being able to foam, let dwell, then swap tips and rinse without moving to a different tool is a nice workflow.

Ergonomics, noise, and control

Noise is low; think loud shop vac rather than small engine. Vibration through the wand is minimal, and the trigger is comfortable enough for longer sessions. The three speed settings let you match power to the task, and Boost is instantly noticeable without being uncontrollable. The 25-foot hose length is adequate for a typical driveway, though a longer hose would be nice for bigger yards or larger vehicles.

On-board storage is mostly excellent—hoses and the foam bottle have dedicated spots, and there’s an internal compartment for odds and ends. One quirk: the on-wand nozzle caddy can let tips work loose if you’re dragging hose through the yard. I started storing the extra tips in the enclosed compartment instead, which solved it.

Maintenance and care

There’s not much to babysit. Rinse the foam bottle after use, keep the filters clean, and let the pump run briefly without detergent to clear lines. Before freezing temperatures, purge water from the system and hoses; a splash of pump saver is cheap insurance. Check quick-connects for grit to preserve O-ring life.

What it won’t do

• Strip paint or heavy stains from concrete quickly
• Match the pace of a 2,500–3,500 PSI gas unit on large surfaces
• Run all afternoon on a single pair of batteries if you park it in Boost

That’s not a knock—it’s a reminder to set expectations. This washer is built for convenience and control over brute force.

Value and ecosystem

Including two DCB612 12.0 Ah FLEXVOLT batteries and two chargers meaningfully affects the value proposition. If you’re already on the FLEXVOLT/20V MAX platform, this washer slots into your kit and the batteries serve double duty. If you’re not, this package still makes sense because the runtime is genuinely useful and the battery value is significant on its own. The 3-year limited warranty adds a layer of confidence without changing the fundamental calculus: this is a premium, portable solution for everyday cleaning.

Who it’s for

• Homeowners who want a cordless washer for cars, patios, siding, windows, grills, and general clean-up
• Detailers and mobile users who need to work away from water and power sources
• Tradespeople who want quick cleanup on jobsites without fuel, noise, or cords

Who should look elsewhere:
- Users whose primary goal is restoring stained concrete, stripping decks, or cleaning large driveways at speed

Recommendation

I recommend this DeWalt cordless washer for anyone who values portability and convenience over maximum blasting power. It nails the everyday jobs—vehicle washes, patio refreshes, siding cleanups—while sparing you the hassles of gas engines and extension cords. Runtime with the included 12.0 Ah FLEXVOLT packs is genuinely practical, the self-priming feature broadens where you can work, and the integrated foam cannon and on-board storage make the whole package feel well thought out. If your cleaning needs regularly demand more than 1,600 PSI and 1.2 GPM, step up to a higher-output machine. For everything else, this is a capable, quiet, and versatile cordless solution that earns its place in the garage.
