DeWalt Pressure Washer

DeWalt Pressure Washer

DEWALT has been a leading manufacturer of high quality tools like chainsaws, drill presses, and table saws for decades but they also make some pretty great pressure washers.

The company originally started their business by introducing their patented woodworking machines and saws. They quickly gained popularity at the construction and furniture gas powered pressure washer.

Now DEWALT has added pressure washers to their product lineup. The pressure washers manufactured by the company are mainly gas powered and are powerful as well as known for their durability. So cost of the products is marked by their quality and features provided.

And honestly, just look at these things. These power washers are for serious men and women, not the weekend driveway washer (electric pressure washers would be a better fit for that). No, these beasts are meant for the tough jobs like when you want to wash away that dirty feeling from your last trip to New Orleans.


Size and Weight

Power cleaners such as the DeWalt DCPW550 aren’t much bigger than a pressure washer wand. From tip to tail, this one measures 40.5 inches. Its weight is on the heavier side for this class of tool—7.4 pounds with a 5.0Ah battery. As a two-hand tool, it’s not that burdensome. For the way we’ve been using it, we’d much rather have the higher performance DeWalt offers than to trade it off for a little less weight.


This is one of only a couple of models to have multiple speeds. High gives you the best performance and low extends your runtime. We have plenty of DeWalt batteries, so we don’t worry too much about conserving the battery and run in high all the time.

No Pressure Required

One of the great benefits of power cleaners is that they don’t need a pressurized water source to operate the way pressure washers do. DeWalt includes a 20-foot siphon hose with both the bare tool and kit. Drop it in a bucket of water, drum, rain barrel, or even the lake. As long as it’s a fresh water source, you’re good to go.

Nozzle Storage

DeWalt makes an unusual move by working with standard pressure washer nozzles instead of the rotating nozzles that come on most power cleaners. We’re totally good with that call, especially since you can store 3 spares on the tool itself.

It comes with 15°, 25°, 40°, and turbo nozzles, so with one on the wand, you have everything you need right there if you need to make a change on the fly.

Water + Electricity

The idea of running a tool like this and splashing water around sounds like a bad idea for the batteries. DeWalt takes care of it neatly with a battery cover to protect it. There’s no gasket around it, though, so it’s really just a splash guard.

What to look for in a pressure washer

You can’t just pluck any pressure washer off the shelf: These machines (particularly gas pressure washers) are incredibly strong. It’s what makes them so effective, but it also means there’s a higher risk of injury and surface damage if you don’t know what you’re doing. Here are a few things to note:

  • PSI: PSI, or pounds per square inch, indicates the water pressure delivered by the machine, says Adrienne Hunt, associate merchant for Home Depot. Pressure washers with a high PSI will clean deep stains more effectively than machines with a lower PSI. Electric pressure washers typically range from 1,600 PSI to 2,300 PSI, while gas pressure washers range from 2,700 PSI to 4,400 PSI.
  • GPM: Though PSI is important, you can’t rely on it alone. “PSI and GPM, or gallons per minute, in tandem are super important,” says Rachel Rothman, chief technologist and director of engineering at the Good Housekeeping Institute. “One without the other won’t result in the right combo.” GPM measures the volume of water delivered by the pressure washer — an indicator of how quickly your machine will clean. Higher GPM pressure washers will clean faster than those with lower GPM, says Hunt.
  • Safety: When using pressure washers, particularly more powerful gas models, you can readily cause bodily harm and surface damage like splintering if you’re not careful, says Rothman.
  • Portability: Pressure washers, especially gas-powered models, can be hefty, weighing up to 55 pounds or more. They can be a chore to take out, put away, or load in the back of a pickup truck. If transporting the washer is essential, look for a compact, lightweight model; some weigh as little as 15 pounds and include attached carrying handles.

Gas vs. Electric

For those who have large areas to clean, such as a pool deck, a patio, or tall exterior walls, the superior cleaning power of a gas pressure washer is the best bet. These machines provide the most mobility and power. They don’t tether the machine to an outlet, so you can move around more easily, plus their higher pressure gets the job done faster.

For smaller, simpler chores like cleaning outdoor furniture, the family car, or just a few feet of exterior space, electric pressure washers offer different benefits. They’re generally quieter and lighter than their gas-powered counterparts.

These plug-ins don’t offer quite as much mobility, but the best electric pressure washer will typically include a 30-foot or longer cord, in addition to a long pressurized hose that can stretch the perimeter of the job site. Be sure to keep the socket, plug, and your hands completely dry when connecting and disconnecting the cord.

Do pressure washers need to connect to a water tap?

You’ll need to connect your pressure washer to a water source. Most often, that source will be an outdoor tap, and you’ll use your garden hose to connect the tap to the pressure washer. Most pressure washers require a garden hose that’s less than 50 feet long and with at least a ¾-inch inside diameter.

If you don’t have access to an outdoor water tap, you still have options. One is to use the water tap for your washing machine. Those taps are threaded the same as an outdoor hose tap, so you’ll be able to hook up the hose without need of an adapter. You can also use a kitchen or bathroom sink. But as these are not threaded for hose attachments, you’ll need a threaded adapter sized for the tap as well as your hose. When using an indoor tap, you’ll need to run your garden hose inside through a window or door, so plan accordingly.

What is a good psi rating for a pressure washer?

Pressure washers range between 1,000 and 4,000 psi. A machine will clean away light stains at the lower range, but heavy stains typically require a psi of 2,500 or higher.

Why does my electric pressure washer keep shutting off?

It may be overheating, have a clog in the line, or have a more significant problem. Try turning off the machine, disconnecting the hose and wand, and then reconnecting and trying again. If that doesn’t help, contact the manufacturer.

How do you winterize a pressure washer?

Flush the pressure hose from the washer and store it separately. Drain the gas tank or add a fuel stabilizer to the tank to keep the gas from separating and clogging the interior working parts over the winter.

What is a good PSI and GPM for my pressure washer?


  • The higher the GPM (water flow rate) the faster you can complete cleaning jobs.
  • Professionals prefer 5-8 GPM because it means they can make more money per day.
  • But for around the house the PSI and GPM you need depends on what you’re using your pressure washer for.


  • PSI represents the force of water to knock the dirt/moss/mildew loose from the surface.
  • 1,400 PSI – 2,500 PSI will do the trick for 90% of jobs since you adjust the pressure with a nozzle/orifice size and moving closer/further from the surface.
