For anyone looking for some serious cleaning power, pressure washers are essential. The best pressure washers make light work of otherwise heavy-duty cleaning tasks, taking grime off vinyl siding, clearing dirt from driveways, and more. Instead of needing to sand, scrub, and scrape for hours, pressure washers do the hard work for you.
We tested several top-rated pressure washers, ranging from lightweight, portable devices perfect for smaller cleaning jobs to heavy, sturdy beasts that would impress trained professionals.
The Karcher K4 Power Control (available at Walmart for $269.97) is the best pressure washer for its versatility; it’s an ideal choice for homeowners and professionals alike. If you’re looking to save some money, you can’t go wrong with the impressively powerful Wholesun 3000PSI (available at Amazon).

We tested pressure washers by blasting mud and paint.
Pressure washers are not the same as power washers. The major difference between the two is that power washers heat up water to aid in cleaning. Typically, the best power washers are specialists and are reserved to remove mold, mildew, and heavy-duty stains like oil.
PSI: Pounds per square inch is the overall amount of power each pressure washer can put out. GPM: Gallons per minute measures the water flow rate
If the exterior of your house is made of hardboard, rock-dash, bottle-dash, or similar material, you should avoid pressure washing your walls. For safety’s sake, you should remember to cover any outdoor outlets, avoid using ladders while operating a pressure washer, and be wary of debris falling off your home or being kicked up off the ground.
We suggest you start with the 25- or 40-degree tip of the pressure washer for cleaning siding. You should start washing from top to bottom to more efficiently deal with falling grime.
When you start your pressure washer, stand about three feet away from your target, and move toward it, as needed. This way, you’ll avoid applying too much pressure and damaging the surface you're trying to clean.
Pressure washers can damage lawns and shrubbery. So when you’re pressure washing walkways and patios, cover your delicate plants with plastic sheeting or drop cloths. You'll need to be careful and avoid outdoor furniture as well, although some cushions may fare OK using one.
While pressure washers have motors, a strong and even flow is required for them to work. One of the best garden hoses we’ve tested should do the trick.
Most of the best pressure washers feature some type of detergent loading system.
Always read the owner’s manual to see what each model recommends. Beyond that, most pressure washer detergents come in the form of concentrates. That means you premix the solution with water before you place it into the unit.
This also means you should wear protective gloves while handling the cleaning solution.
There are some guides out there that suggest making a bleach solution for dealing with mold. We would not recommend that. Bleach is pretty toxic and having it splattered everywhere will not do you or your yard any favors.
Many hardware stores, like The Home Depot provide pressure washers to rent. For one-time jobs, it can totally be worth it.
For example, if you’re planning on giving your house a once-over before putting it on the market, renting a pressure washer might be a good idea. However, if you’re settled in and planning on doing some cleaning every spring and summer, owning a pressure washer will pay for itself.
Electric pressure washers are fairly simple to winterize. All you need to do is drain all the hoses and detergent tanks. To drain the hoses, detach them, unroll them, and hold them up—all the water should drain out.
Detergent tanks are also fairly simple. You can clean them out by simply flushing them out with a hose. Just be sure to let them dry out before storage. If you store your pressure washer in the basement, you can place it near a low-powered space heater to prevent any freezing.
If you live in a colder climate, you may also opt to fill the unit with anti-freeze designed for small pumps.
We painted blue squares on our brick exterior wall to see which pressure washers could clean it the best.
While gas-powered pressure washers are also an option, we tested a number of the top-selling electric models across the market. All of them are marketed to homeowners, and we found that smaller machines with a lower intensity did the job just fine, even if they’re more light than heavy-duty.
Look at the box of any electric or gas pressure washer, and you'll see something about PSI, GPM, or Amps. While all those specs are valuable, the important things are whether the pressure washer can clean well and if it is easy to use.
To test cleaning power, we painted vinyl, wood, aluminum, brick, and asphalt, then covered each with half an inch of compacted dirt. We blasted each of these surfaces with the pressure washers on various settings and gauged how easily we could get rid of the dirt and not damage the paint. After the tough but gentle approach, we went full bore and tried to strip the exterior and spray paint off of all the surfaces.
Stripping paint is a tough job, even for a pressure washer.
The best pressure washers of the bunch presented one last challenge: a clogged gutter. This gutter wasn't clogged with leaves but a man-made pseudo-sandstone created by mixing sand and flour. We tested to see if it could blast through without damaging the gutter.
We also tested each device’s soap-cleaning feature. We filled each soap intake tank or bottle with a pint of generic pressure washer detergent mixed with water, got a feel for how uniform the soap spray was, and noted how long the suds lasted.
