In this DeWalt DWPW2400 pressure washer review, you’ll find all the information you need to help you decide on whether this is one of the best pressure washers for you. We’ve included size and efficiency, the good and bad points, and a round-up of real life user opinions. 

The DeWalt DWPW2400 is aimed at the domestic market, making it suitable for everyday jobs such as cleaning driveways and patio furniture, as well as washing the car. While it will tackle larger projects, you may find it takes a while as this washer isn’t at the top of its class for power. The price point is towards the higher end for its market position but it carries the backing of the DeWalt name. This pressure washer is a neat little unit that comes with a range of five nozzles, meaning it’s suitable for most jobs. It’s electric rather than gas-powered, making it quieter, more environmentally friendly, and more convenient to use. The lack of a gas tank makes it lighter, as well.

DeWalt DWPW2400: Essential info

Weighs 45.2lb
Costs around $300
35 feet hose
Cold water capacity
Pneumatic wheels
5 nozzles and built-in storage
3 year limited warranty
Maximum pressure 2400 psi
Wand storage for ease
Separate detergent tank

This DeWalt model delivers 2400 PSI (pounds per square inch) of pressure, and a less-than-average 1.1 GPM (gallons per minute). To calculate efficiency you need to take both those measurements into account (the GPM is how fast the water comes out, the PSI is how forcefully it comes out). For ease, you can multiply the two measurements together to give what’s called cleaning units (CU) – in this case, 2,640, which is below average for the price bracket.

The unit has storage for the cord, hose, nozzles, and wand making it efficient to store. As it’s electric rather than gas, so you will need access to a power outlet, but you can use the unit with an exterior 13-amp compatible extension cord to help extend your reach. You’ll also need to connect it to a cold-water tap.

The DeWalt 2400 PSI 1.1 GPM pressure washer may be top of its class price-wise but you’re paying for reliability, good customer service, and a three-year limited warranty.

DeWalt DWPW2400: How big is it?

  • Depth: 21.26 inches
  • Width: 19.68 inches 
  • Height: 20.98-inches    

The DeWalt DWPW2400 pressure washer packs a decent punch for its size but it’s not top of its class. 

If you regularly have to clean large areas – perhaps you have a very long driveway, for instance – then you might like to consider commercial models which will make life easier. This machine may be priced towards the higher end of the domestic market, but a good commercial pressure washer will set you back around double the cost of this one.

DeWalt DWPW2400: Functions and features

This unit has 10-inch pneumatic wheels and comes with a 35-foot power cord and 25-foot kink-resistant hose. The maximum flow rate is 1.1 gallons per minute (GPM), although this varies a little depending on which nozzle you are using. The power comes from a brushed motor, which requires a 13 amp 120v electric power supply.

It comes with five nozzle attachments including a turbo nozzle, soap nozzle, 15-degree nozzle, 25-degree nozzle, and a 40-degree nozzle. Generally speaking, the smaller the angle on the nozzle the more directed and stronger the spray will be. The 40-degree nozzle will give a fine spray while the 15-degree one will give a powerful but narrow jet. The turbo nozzle creates a narrow jet of water then spins it to create a cone. It’s important to choose the correct nozzle for the job at hand, so refer to your unit’s instructions when starting a new project – using the wrong nozzle can damage your belongings. 

Other features include a wand, hose, power cord and nozzle storage, and an integrated detergent tank which is removable for easy refilling. 

DeWalt DWPW2400: What’s good about it?

The DeWalt 2400 PSI 1.1 GPM pressure washer is a neat little machine that is easy to transport. As it’s powered by electricity rather than gas, it’s quiet to run and won’t annoy the neighbors on a Sunday morning! It comes with a good range of nozzles to tackle most household jobs. The wheels are pneumatic, which makes it easy to maneuver over rough ground. The PSI of 2400 is good for a domestic unit and will make light work of smaller cleaning jobs. 

It’s easy to change the nozzles over too - you simply unclip the one you’re using and re-clip the next. It comes with a three-year limited warranty, a one-year free service plan, and a 90-day money-back guarantee. Replacement parts such as nozzles and wands are available separately. Most pressure washers should come with a lengthy warranty and two to three years is fairly standard. The Stanley SLP 2050 2-in-1 pressure washer, for example, is comparable for power but only has a two-year warranty and no service plan. 

DeWalt DWPW2400: What’s not good about it?

The price of this model is towards the top end for a domestic pressure washer, and other washers in a similar price range are more powerful so you could find yourself limited with really large jobs. 

The hose and power cord lengths (25 and 35 feet respectively) may be a bit limiting, but they’re in line with models by other manufacturers. While the unit comes with a range of nozzles it has no brush attachments, which can be useful for specialist jobs such as car washing. The handle does not fold down for storage, so you’ll need space to park your pressure washer when it’s not in use. 

A downside for those who prefer to buy domestic is that this unit is made in China, and there’s also no information available about eco-efficiency. It’s also relatively heavy at just over 45lb; other similar washers tend to weigh in at around 32lb, such as the Karcher K5 Premium Electric Pressure Washer

DeWalt DWPW2400: How efficient is it?

Electric pressure washers in general are relatively energy-efficient, using roughly 1,500 watts/hour for domestic models. Depending on your state and power supplier, that’s in the region of 15 to 30 cents an hour. This model offers 2400 PSI and a flow rate of 1.1 GPM (gallons per minute). While other pressure washers may have better GPM rates, this model offers high pressure and should clean efficiently so that you use less water for your project. The wand also has a trigger action so that you can use the water flow only when needed.

DeWalt DWPW2400: User reviews

Reviews for this model are a little mixed with users either loving or hating it. Overall, it scored 4 out of 5 stars on Home Depot, meaning most customers were happy with their purchase. Several reviewers singled out the wand storage, saying that it wasn’t secure and didn’t hold the wand properly.  

A good product for the price, works great [but] needs a longer extension cord.

Home Depot customer review

A small number of users had had problems with the hose and ended up replacing it. Others commented that it was powerful and easy to use. The majority of customers were happy with the performance of the pressure washer and found it coped well with most domestic jobs. 

Should you buy the DeWalt DWPW2400?

The DeWalt 2400 PSI 1.1 GPM pressure washer is one of the more expensive models available in its sector, but cheaper models tend to be less powerful. The American brand DeWalt has a reputation for quality and tends to command slightly higher prices as a result. This washer should tackle most average domestic jobs, but you have a particularly large driveway (or a particularly dirty car!) then you might like to think about investing in a professional rather than domestic model.

The fact that it’s electric rather than gas means it’s much quieter and you don’t have to store the gas, but you will need access to a convenient power outlet. Overall, DeWalt is a popular brand with a good reputation and this high-end domestic pressure washer should suit most householders. 

If this model isn’t for you… 

The DeWalt DWPW2400 pressure washer won’t be for everyone so if you’re looking for something different, we’ve got you covered. If power is high on your agenda, a gas model such as the RYOBI RY803001 3000-PSI Power Control

Alternatively, if budget is your biggest deciding factor, the Sun Joe SPX3000 Electric Pressure Washer offers great value for money.
