DeWalt 2400 PSI 1.1 GPM Electric Pressure Washer

Why I reached for this electric washer

I’ve used a lot of gas washers over the years for their speed and brute force, but I wanted something quieter and easier to live with for routine home maintenance. The DeWalt 2400 checked the right boxes on paper: modest power draw (13 amps on a standard 120V circuit), 2400 PSI with a measured 1.1 GPM using the 15° tip, an integrated detergent tank, and a tubular steel frame on big pneumatic tires. After several weekends cleaning patios, siding, and a very green fence, here’s how it actually behaved.

Setup, power, and first impressions

Assembly is minimal: handle, wand, hose, and nozzles dock onto the frame, and everything has a dedicated parking spot. The on-board storage is genuinely useful—nozzles snap into a steel plate, the wand and spray gun have a cradle, and the power cord and hose have clear wrap points. My unit did arrive with a small scuff on the edge of the nozzle plate where it had rubbed in transit, but nothing structural.

Power is via a 35 ft GFCI cord. I ran the washer on a dedicated 15A outlet without issue. If you need an extension cord, go heavy gauge (12 AWG) and keep it short. Before the first start, I connected a 5/8 in garden hose, turned water on fully, squeezed the trigger to purge air, then switched the unit on. Do that every time—bleeding the air helps avoid the motor “hunting” and gives you full pressure immediately.

Design and ergonomics

At 45 lbs, it’s not featherweight, but the 10 in pneumatic wheels and the steel frame make it easy to roll over pavers, lawn, and gravel. The footprint is compact (about 21 x 21 x 20 in), so it stores upright against a wall. The spray gun feels sturdy, and the metal lance is a step above the plasticky setups on bargain models.

The included 25 ft “kink-resistant” hose is serviceable but still prone to memory and loops. It’s the one part I’d upgrade immediately to a 50 ft polyurethane or hybrid hose; you’ll move the machine less, and it’s far less frustrating to manage. Quick-connects on the gun, hose, and pump save time and keep the threads in good shape.

Performance: what 2400 PSI and 1.1 GPM really means

This washer is high pressure with relatively low flow. That combination excels at cutting through stuck-on grime in a concentrated strip, but it moves less water, so rinsing and covering large areas takes longer than with a 2.0–2.5 GPM gas unit.

• Concrete and pavers: Using the turbo nozzle, I stripped a winter’s worth of algae and dirt from patio pavers, a section at a time. The turbo cone accelerates the job, but it’s aggressive; keep it moving to avoid etching soft concrete. With the 15° tip, I got the best balance of speed and control. A 12–15 inch surface cleaner works, but the lower flow means you’ll move slower than with a higher-GPM machine.
• Vinyl siding and soffits: The 25° and 40° tips are the right call here. At a safe standoff (12–18 inches) the washer cleared mildew and spider webs without punching water under the laps. It’s quiet enough that I didn’t feel like I was announcing the job to the whole neighborhood.
• Wood fencing and decking: I prefer the 25° and a gentle, methodical pass. The machine has enough pressure to raise the grain if you get too close. On an older cedar fence, I kept a steady 18–24 inch standoff and got a clean, even result ready for brightener.
• Vehicles and small equipment: With the 40° tip and light touch, it’s good for pre-rinse and bug removal. The lower GPM shows up when trying to flush heavy mud from wheel wells—you’ll get there, but you’ll spend more time.

If you’re trying to de-grease equipment, clean a barn aisle quickly, or blast a large driveway, the 1.1 GPM will feel slow. For household maintenance, patios, and seasonal cleanups, it’s effective—just expect to trade speed for a quieter, easier operating experience.

Detergent use and the soap circuit

The integrated detergent tank is handy for siding or vehicle soap. As with many electrics, soap only draws with the low-pressure Soap nozzle installed. Priming takes a moment: run clean water first, then switch to soap and let it pull until you see suds. Metering is fixed (no dial), so I mixed to the job in the tank.

Two practical notes:
- Treat the tank fittings gently. They’re plastic and feel like the most delicate bits on the machine.
- Always flush the soap line with clean water after use to avoid clogs and sticky valves.

I preferred relying on water and dwell time for most tasks; I reserved detergent for oxidized siding, greasy spots, and vehicles.

Noise, heat cycling, and day-to-day usability

One of the best parts of this washer is how quiet it is when you’re off the trigger—there’s no idling engine, just silence. Under load, it’s a steady electric whirr, easily conversation-level.

I did encounter one hiccup during a long session: after about 20 minutes of intermittent use, the motor refused to re-start once when I released and re-squeezed the trigger rapidly. I relieved the pressure, reset the GFCI, and let it sit for five minutes; it came back and finished the job. It never repeated, but it’s a reminder to give the pump good water flow and to purge air before flipping the switch. Keep the garden spigot fully open, avoid restrictive hoses, and don’t starve the inlet filter.

Build quality and serviceability

The steel frame inspires confidence and protects the pump and motor. The wheels are a win over hard-plastic casters—no drama when you tug the hose. The gun and lance feel robust, the nozzles store securely, and the cord’s GFCI is easy to access.

On the flip side:
- The hose is the weakest link in the experience. It kinks and fights you around corners.
- The detergent hardware is functional but the plastics are light. I’d avoid overtightening and keep a spare O-ring kit on hand.
- The unit arrived with mild cosmetic scuffing on the nozzle plate. It didn’t affect function, but I wiped it with a dab of paint to keep rust at bay.

CETA certification is reassuring, and DeWalt backs it with a 3-year limited warranty. For longevity, use a pump saver before winter, avoid dry running, and store it dry with the trigger locked open to relieve pressure.

Tips that improved my results

• Bleed air every start: water on, trigger squeezed, then power on.
• Use the 15° tip for most cleaning; save the turbo for stubborn areas.
• Add a 50 ft, 1/4 in non-marking hose and brass quick-connects to cut setup time and frustration.
• Pair with a small surface cleaner for patios—the flow will limit your pace, but it evens out results and saves your back.
• If you must use an extension cord, 12 AWG, under 50 ft, and fully uncoiled.

Who it’s for

• Homeowners who want low-hassle, quiet cleaning for patios, siding, fencing, furniture, and vehicles.
• Townhouse or urban users where noise and exhaust are dealbreakers.
• Anyone who values a tidy, self-contained cart with real tires and good storage.

Who should look elsewhere:
- Folks needing fast rinsing and heavy flushing (barns, tractors, large driveways). You’ll want 2–3 GPM and likely a gas unit.
- Users who rely heavily on detergent application and want adjustable metering or industrial-grade soap plumbing.

Pros and cons

Pros:
- Quiet, low-vibration operation; no fuel, fumes, or winterizing headaches.
- Solid frame, real tires, and excellent on-board storage.
- Useful nozzle set including a turbo tip; metal lance and sturdy gun.
- 35 ft GFCI cord extends reach without an extension cord.

Cons:
- Low flow (1.1 GPM) slows big jobs and heavy rinsing.
- Stock hose kinks and feels short at 25 ft.
- Detergent fittings feel delicate; treat with care.
- I experienced a single heat/pressure-related restart quirk during extended use.

Recommendation

I recommend the DeWalt 2400 for homeowners who prioritize quiet operation, tidy storage, and capable cleaning power for routine maintenance. It does excellent work on patios, siding, fences, and vehicles, and the ergonomics make it easy to live with. The tradeoffs are real: the 1.1 GPM flow means you’ll take more time on large surfaces, and the hose and detergent hardware are weaker links. Buy from a retailer with a straightforward return policy, inspect for shipping scuffs, upgrade the hose, and follow good operating habits (purge air, don’t starve the pump, use pump saver for storage). If speed and heavy rinsing are your top priorities, you’ll be happier with a higher-flow gas unit; otherwise, this quiet electric is a well-rounded, convenient cleaner for most household jobs.
