DeWalt Power Washer Guide: Gas, Cordless or Handheld?

DeWalt is best known for yellow-and-black power tools and its 20V MAX battery system, and the name also appears on gas pressure washers built for homeowners. If you are shopping for a “DeWalt power washer” (or typed “dealt power washer” in a hurry), you will find two very different kinds of machines: big gas washers on wheels for decks and siding, and small cordless cleaners that run on a 20V battery.
These six differ mainly in power source and brand: two DeWalt gas washers, one genuine DeWalt 20V cordless cleaner sold renewed, and three handheld washers from other brands built to fit DeWalt 20V batteries.
DeWalt Power Washers Compared
| Model | Power source | Max pressure | Max flow | Hose length |
|---|---|---|---|---|
| DeWalt 3300 PSI Gas Pressure Washer | Gas, 208cc engine | 3300 PSI | 2.4 GPM | 25 ft |
| Dewalt DCPW550BR 20V MAX 550 PSI | DeWalt 20V battery | 550 PSI | 1 GPM | Listed as 20 meters |
| Cordless Portable Washer for Dewalt 20V (ZixDeNex) | DeWalt 20V battery | 1000 PSI | Not listed | 16.5 ft |
| DeWalt PressuReady 3400 PSI Gas Pressure | Gas, 208cc engine | 3400 PSI | 2.5 GPM | 25 ft |
| Cordless Portable Washer for Dewalt 20V (SXBSXB) | DeWalt 20V battery | 1100 PSI | Not listed | 23 ft |
| Cordless Portable Washer Compatible with Dewalt | DeWalt 20V battery | 700 PSI | 2 GPM | 16.4 ft |
Two terms explain most of this table. PSI (pounds per square inch) is how hard the water hits the surface; higher PSI strips stubborn grime faster. GPM (gallons per minute) is how much water flows; higher GPM rinses larger areas more quickly. Gas washers win on both, while cordless tools trade power for convenience.
DeWalt 3300 PSI Gas Pressure Washer for Everyday Home Jobs

DeWalt 3300 PSI Gas Pressure Washer
Best for: Homeowners cleaning decks, siding and patios
Pros
- 3300 PSI at 2.4 GPM
- 5 quick-connect nozzles
- 25-ft hose, 10-inch pneumatic tires
Cons
- Pull-start gas engine
- 64 pounds to move
The DeWalt 3300 PSI Gas Pressure Washer (model DXPW3300-S) uses a DeWalt 208cc engine and an OEM Technologies axial cam pump rated at 3300 PSI and 2.4 GPM. The listing describes a welded steel frame with a powder-coated finish, a thermal relief valve that helps stop the pump from overheating, and 10-inch pneumatic (air-filled) tires for rolling over uneven ground. It measures 41 x 21 x 24 inches and weighs 64 pounds.
In the box you get a 25-foot abrasion-resistant hose, five quick-connect nozzles (0°, 15°, 25°, 40° and soap), a spray gun and a 16-inch steel wand. The nozzle angle controls how the water fans out: 0° is a narrow, powerful jet, while 40° is a wide, gentle spray for delicate surfaces. The listing says it is 49-state compliant and that factory-tested units may arrive with a little residual fuel or odor.
This is the straightforward pick for a first-time homeowner who wants to clean decks, patios and siding or prep a house for painting. It starts with a standard engine, so if a pull cord worries you, the PressuReady model below removes that step.
Dewalt DCPW550BR 20V MAX 550 PSI for Tool and Gear Cleaning
Dewalt
Dewalt DCPW550BR 20V MAX 550 PSI Cordless Power Cleaner (Tool Only) (Renewed)
Price and specifications are read from the Amazon product page and can change.
Dewalt DCPW550BR 20V MAX 550 PSI
Best for: DeWalt 20V owners washing tools and gear
Pros
- Genuine DeWalt 20V MAX tool
- Draws from buckets or garden hose
- 4 nozzles plus soap bottle
Cons
- Renewed, 90-day limited warranty
- Only 550 PSI, battery not included
The Dewalt DCPW550BR 20V MAX 550 PSI cordless power cleaner is the only genuine DeWalt cordless model here, and this listing is an Amazon Renewed unit, meaning it has been inspected and resold rather than sold new. It carries a 90-day limited warranty and is sold as the tool only, so you need your own DeWalt 20V MAX battery.
It is rated at 550 PSI and 1 GPM, which the listing describes as 10 times the cleaning power of a garden hose. It can pull water from any fresh water source through an included suction hose, or connect to a garden hose with a quick connect adapter. It comes with four nozzles that store in the unit and a soap bottle. The hose length is listed as 20 meters, which seems long for a suction hose, so check the product page if reach matters.
Think of this as a rinsing tool for outdoor furniture, boats, bikes and muddy job-site equipment rather than a deck stripper. For more on DeWalt’s own battery models, see our guide to the DeWalt battery pressure washer range.
Cordless Portable Washer for Dewalt 20V with 1000 PSI

Price and specifications are read from the Amazon product page and can change.
Cordless Portable Washer for Dewalt 20V
Best for: Light car and fence rinsing
Pros
- Up to 1000 PSI claimed
- 6-in-1 twist nozzle
- Weighs about 16 ounces
Cons
- Third-party brand, not DeWalt
- Battery not included
The Cordless Portable Washer for Dewalt 20V in this listing is made by a brand called ZixDeNex, not DeWalt. It is built to accept DeWalt 20V lithium-ion batteries such as the DCB206, DCB204 and DCB181, but the battery is not included. Because it is a third-party tool, DeWalt’s own support and warranty do not apply; the seller offers its own after-sales service.
The listing claims up to 1000 PSI from a 380W brushless motor, three power levels and a spray reach of about 32.8 feet. A 6-in-1 nozzle twists between 0°, 15°, 25°, 40°, angled spray and fine shower. The kit includes a 16.5-foot hose, foam sprayer, water filter and two quick connectors, and the tool weighs about 16 ounces.
It suits someone who already owns DeWalt batteries and wants a light washer for cars, fences and walls. Flow rate is not listed, so do not expect gas-washer rinsing speed.
DeWalt PressuReady 3400 PSI Gas Pressure Washer with Quick Start
Dewalt
DeWalt PressuReady 3400 PSI Gas Pressure Washer, 2.5 GPM, 25-ft Hose
Price and specifications are read from the Amazon product page and can change.
DeWalt PressuReady 3400 PSI Gas Pressure
Best for: Buyers who hate pull cords
Pros
- 3400 PSI at 2.5 GPM
- Trigger-activated Quick Start
- Smart control panel with fault LEDs
Cons
- Heaviest at 76 pounds
- Starter battery sold separately
The DeWalt PressuReady 3400 PSI Gas Pressure washer (model DXPW3400PRNB-S) is the most powerful machine here at 3400 PSI and 2.5 GPM. Its main selling point is PressuReady Quick Start: you squeeze the spray gun trigger and a battery-operated electric starter fires the 208cc engine, with no choke or recoil rope. It shuts off after a few seconds of inactivity to save fuel and reduce noise.
A smart control panel shows LED indicators for ready mode, water flow and faults like no fuel or low battery. The starter runs on a DeWalt 20V MAX or FLEXVOLT battery, which is not included. You also get a 25-foot MorFlex hose, five quick-connect nozzles, a spray gun and 16-inch steel wand. The listing names FNA Group as the manufacturer and gives a weight of 76 pounds.
Pick this one if you want gas power without wrestling a pull cord, and you already own a DeWalt 20V battery. If you do not, the 3300 PSI model avoids the extra battery purchase.
Cordless Portable Washer for Dewalt 20V with Storage Case
The second Cordless Portable Washer for Dewalt 20V comes from a brand called SXBSXB (model PW-12). It is sold as a bare tool that fits DeWalt 20V MAX batteries, with no battery or charger in the box, and it is not a DeWalt product.
The listing claims up to 1100 PSI from a 350W brushless motor, three modes on a touch-control display, a 23-foot hose with a weighted filter head for drawing water from a bucket or pool, and a 6-in-1 nozzle with wide fan and shower options. It includes a 400mL foam bottle, faucet connector, hose valve and a hard plastic storage case, and weighs about 3.5 pounds.
The long hose and case make it a tidy car-washing kit or gift for someone with DeWalt batteries in the garage. For a plug-in alternative, our DeWalt electric power washer guide covers corded options.
Cordless Portable Washer Compatible with Dewalt for Light Rinsing
The Cordless Portable Washer Compatible with Dewalt is sold by a brand called XGVGWJZ and, like the others, is tool only with DeWalt 20V batteries recommended. It lists 700 PSI and 2 GPM from a 380W brushless motor, with four pressure settings.
The kit includes a 16.4-foot hose, dual filters for bucket, pool or lake water, 3/4-inch threaded fittings, a foam cannon and a 6-in-1 nozzle. At about 2.8 pounds it is the lightest washer in this list. It suits quick rinses of vehicles and patio furniture where a gas washer would be overkill.
How to Choose the Right DeWalt Power Washer
Match power to the job. For decks, driveways and siding, choose one of the gas models; the 3300 PSI and 3400 PSI units are the only ones built for that scale. For cars, bikes and tools, a cordless unit is lighter and quicker to set up.
Decide how you want to start it. The 3300 PSI model uses a standard engine start, while the PressuReady 3400 starts from the trigger but needs a DeWalt battery.
Be honest about brand. Only the DCPW550BR is a DeWalt cordless tool, and it is renewed. The three handheld washers are third-party products that fit DeWalt 20V batteries; their PSI figures are the sellers’ claims.
Check your water source. All the cordless options can draw from a bucket or open water, which helps where there is no outdoor tap.
FAQ
Is a cordless washer for a DeWalt 20V battery made by DeWalt?
Not in these cases. Three of the cordless washers here are made by other brands and only fit DeWalt batteries. The DCPW550BR is the genuine DeWalt model.
What does the DeWalt PressuReady 3400 do differently?
It starts when you squeeze the trigger using a battery-powered starter, shuts off after brief inactivity, and has a control panel with status lights.
Do the DeWalt gas pressure washers include a battery?
The PressuReady 3400 needs a DeWalt 20V MAX or FLEXVOLT battery for its starter, sold separately. The 3300 PSI model does not mention needing one.
Is the DeWalt DCPW550 strong enough for a deck?
At 550 PSI and 1 GPM it is aimed at light cleaning of furniture, boats and equipment. For deck and siding work, a gas model is the better fit.
Which DeWalt power washer is best for beginners?
The 3300 PSI gas model is simple, includes everything to start and covers most home exterior jobs. Beginners who only wash cars may find a cordless unit easier.
