One day you look at your house and grimace. How did it get so dirty? On closer inspection, you can see grime and muck in every crevice. The external windowsills are so filthy you could write your name in them.

Not good.

Dirt builds up gradually on the exterior of a house so you might not realize the state of the it for a while. Once you notice it though, you can’t stop looking. Luckily, it’s easy to solve. Finding the best power washer for your needs means your home will never look dirty again.

Not all power washers are the same though and the last thing you want is a power washer that’s more like a gentle shower. We’re going to take a deep dive into the best power washers for homes, how they work, and what you should look out for.

Whether you’re looking to sell your home and need to boost its appeal or just want to keep it looking great, read on to discover the Best power washer for home use.

How Power Washers Work 

Power washers connect up to your garden hose and pull water through a pump system. This system puts the water under intense pressure to accelerate it out of the nozzle into a powerful spray.

Because the water is under pressure and is ejected in a forceful spray, it actually uses considerably less water to clean dirt away than the hose would without the washer.

The water consumption difference between power washers and regular hoses is mammoth. A high-quality power washer can use around 1000 liters per hour compared with the 3500 liters per hour of a standard hose. And you won’t blast off much muck with a standard hose for all that water.

There can be differences in energy type, pressure (PSI), and flow rate. Some of the best power washers are also compatible with a range of accessories to suit the task.

Features of Power Washers

There are many power washers designed for different purposes, from car washing to decking. We’re looking at the best power washer for home use so you can get the outside of your house sparkling.

In order to understand how to choose a power washer, first you need to know what the technical specifications mean and why they’re important.


The force a power washer emits is measured in PSI (pound-force per square inch) or Bar. All power washers will have their pressure measured in these units which makes it easy to compare different washers.

Simply put, the lower the number, the lower the pressure. If you prefer to use one unit over the other, you can convert PSI to Bar easily.

Power washers can range from 800 PSI (55 Bar) to over 3000 PSI (206 Bar).


Electric power washers are sometimes also listed by the power of their motors. This will be listed in either watts (W) or kilowatts (kW). The higher the number, the more powerful the washer will be.

Flow Rate

Flow rate is another measurement that you’ll want to keep an eye out for. Flow rate is measured in liters per hour (l/h) or gallons per minute (GPM). This shows how many liters/gallons of water will pass through your power washer per hour/minute. In reality, you probably won’t be running your washer for a solid hour so the l/h rating will be less in use than stated.

Fuel Type

Power washers come in two fuel types and each has its own benefits and drawbacks.


Using a gas power washer typically gives you higher pressure as well as portability. With no power cords, you can move your power washer around the outside of your house easily.

The drawback here is that gas is typically more expensive and your washer will require lubrication and maintenance to keep it running smoothly.


Lighter-weight and easy use and store, electric power washers are popular. Simply plug them into an extension lead and away you go. They don’t demand much maintenance but should be stored in a dry place.

The drawback is that you’ll need an extension cord long enough to reach all the parts of your building exterior and cords can get in the way.

The Best Power Washer For Home Use

Now you know what technical specifications to look out for are, let’s take a look at the best power washers for keeping your home bright and beautiful.

When you need a competent power washer to get rid of all that muck on your walls and in your gutters, the Sun Joe is a solid choice.

At 31 pounds (without detergent), it’s easy to move around and has two detergent tanks that cumulatively hold 1.8 liters of liquid. This is an ideal electric unit with an impressive 2030 PSI, easily enough to blast off stubborn marks and grime.

If you’re concerned about reach, you needn’t be. The Sun Joe SPX3000 comes with a 35-foot power cord which can be further extended using an extension cord. It has a 20-foot hose as well as a 14-inch extension wand. With this length, you’ll be able to reach into even the most awkward places.

We appreciate that you might not want the same amount of pressure applied to every part of your house. Solid exterior walls will require more pressure than varnished windowsills or even gutters. With the Sun Joe, you stay in total control.

With five spray nozzles that are quick and easy to connect, you can choose from five levels of spray to suit the surface you’re washing.

A clever feature is the Total System Stop, an automatic function that stops the pump when the trigger isn’t in use. This saves you power and reduces wear on the motor.

If you don’t want to deal with electrical cords, this Ryobi is the best gas power washer for home use. The comfortable handle and large wheels make it easy to roll across different surfaces to where you need it to go.

With an on-board detergent tank just like the Sun Joe, it’s easy to fill it once and get on with the job. As a gas power washer, it is noisier than electric versions but it’s one of the quieter gas models on the market.
