Best Pressure Washer Surface Cleaners
Pressure washers are a powerful tool that can turn a 5-hour cleaning job into something you can get done in under an hour.
There is just one problem that people run into.
Often, it can be challenging to clean flat surfaces evenly and efficiently with the standard nozzles that come with a pressure washer.
This is where surface cleaners help.
Surface cleaners have a circular frame with small nozzles placed on a spinning arm, allowing them to evenly distribute the high-pressure water onto a larger surface. So what you get is an attachment that covers a larger area (usually 10 inches or more), instead of a focused water flow with a single nozzle.
As with other pressure washer attachments, you have multiple options to choose from, often making it hard to decide which is best.
To help, we created this guide that goes over the best pressure washer surface cleaners available today, including their pros and cons, who each is best for and much more to help you find your fit.

How Pressure Washer Surface Cleaners Work
Surface cleaners are designed to make your cleaning jobs easier and quicker. They can help you save time and effort while delivering a more consistent outcome. All the magic happens inside the dome-shaped frame that makes up the majority of the unit—so let’s flip it over and see how surface cleaners actually work.
Most surface cleaners have 2-3 spinning arms that are connected to a central spinning axis on one end and small nozzle jets on the other. When the surface cleaner is put to work, the central axis rotates at high speed (usually between 1500-1800 revolutions per minute) and the nozzles release water at high pressure. The rotation, combined with the high pressure, ensures a smooth cleaning process.
Pressure washer surface cleaners are ideal because they clean evenly as opposed to more-focused nozzle tips that clean in straight lines. Common surface cleaners are between 10 and 24 inches in diameter.
Along with quicker cleaning, the rotational jet system ensures streak-free cleaning, helping you avoid the dark and light patterns that develop on your pathways while using regular nozzles.
A good surface cleaner is typically very easy to operate as well. You can simply attach it to your wand and start cleaning. You have to be careful not to leave the surface cleaner over a spot for too long, as this might cause the concrete to chip off. But otherwise, you do not have to worry about holding it too close to a surface or using too much pressure as you would have to for a regular nozzle.
The dome structure of surface cleaners is finished off with brushes all around its diameter. These brushes ensure that there is no splashing of water or mud. As you move the surface cleaner along, the dirty water is slowly released, with some of the impurities getting caught in the brush so you do not have to worry about cleaning that too.
What to Consider When Buying a Pressure Washer Surface Cleaner
1) Compatibility with your pressure washer
The first thing you need to narrow down your selection is to consider what types of surface cleaners your pressure washer is compatible with. Here are some of the specific things to look for:
The pressure generated by a pressure washer is a big factor in choosing your surface cleaner. Say you are using a large diameter surface cleaner (18”+). You naturally need more pressure to ensure that the pressure of the water distributed amongst the different nozzles is high enough and you are able to clean a surface thoroughly.
Similarly, if you are using a small diameter surface cleaner (say 10″) with a machine that falls under a higher PSI count than recommended, it might result in damage to the surface being cleaned or to the surface cleaner itself
The aim is to keep within the range recommended and get the best out of the surface cleaner.
Gallons per minute is a measurement of the amount of water that runs through the pressure washer. The higher the GPM, the faster the job can be accomplished. Similar to the PSI range, a surface cleaner has a defined GPM range and works best within it.
The larger the GPM of your pressure washer, the bigger the diameter of the surface cleaner you can use. This is because the water flows in enough quantity to ensure that a wider surface is cleaned.
Using a pressure washer with a lower GPM will result in an underwhelming performance, whereas one with a higher GPM than advised, might result in damage to the surface cleaner.
Most surface cleaners come with a ⅜” or ¼” quick-connect plug (or both). It is important to check the connections on your pressure washer before making a purchase. If you do not consider this factor, you might have to purchase an additional adapter.
Max water temperature
Like pressure washers, surface cleaners work with either hot or cold water. Hot water surface cleaners come with the benefit of deeper cleaning. However, most pressure washers (and therefore surface cleaners) operate within the cold water range.
Check what kind of water your pressure washer uses and make sure that is ok for the surface cleaners you are considering.
2) Width of the surface cleaner
Want to clean a large surface area in a shorter amount of time? The larger the diameter of your surface cleaner, the more ground you can cover with each swipe. But is bigger always better?
If you use an electric pressure washer—especially a light-duty one—it is best to go with a smaller diameter surface cleaner (10” to 15”). This is because an electric pressure washer will not generate enough pressure or provide enough water to clean a wider area effectively. Gas pressure washers are more powerful and can be effectively used with wider surface cleaners.
You must also take into consideration the size of the surface you want to clean. For example, using a big dome over a narrow path will result in obstructions and improper cleaning, as the dome cannot cover all the nooks and corners.
On the other hand, using a small diameter surface cleaner over a large surface will defeat the main purpose of the surface cleaner, to accomplish the job quickly. It is also possible that using a smaller surface cleaner can cause damage to property and over splash from the large amounts of water being released.
3) Integrated handles vs. non-integrated handles
Integrated handles are a good feature to have in a surface cleaner. They allow you to gain more control over the movement of your surface cleaner, with a much lesser amount of effort. These surface cleaners often come with trigger handles that can be connected to the pressure washer and squeezed to release the water.
Surface cleaners with non-integrated handles can be directly connected to the spray wand. Doing this turns the spray wand into your handle to guide the surface cleaner around. Many surface cleaners come with extension wands too to make the spray-handle longer.
Even though the integrated handles might sound like the clear choice, you have to consider that integrated handles are expensive, occupy a large chunk of space in storage, and are heavy. If you won’t be using the surface cleaner regularly, it might be best to go with a surface cleaner without integrated handles
4) Wheels vs. no wheels
Some pressure washers come with wheels that allow the surface cleaner to glide easily over the surface being cleaned. These wheels also provide additional support to the cleaning assembly. Some surface cleaners come with stainless steel castors, that make it sturdy and allow for 360° movement of the dome.
However, surface cleaners with wheels as supports are more expensive than their counterparts without wheels. Surface cleaners without wheels are stable as well and might be a better option if you are looking for something that costs less and your cleaning jobs are smaller.
5) Customer reviews
Customers that have used the product are a great source to learn about the hard realities of its performance. We have scanned through customer reviews to give you an idea of actual users’ experiences when it comes to all the surface cleaners mentioned in this guide.
You may be able to find out a lot more about the durability and the performance of the product by going through customer reviews. For example, one of the things we discovered was that lightweight and light-duty surface cleaners are often made with plastic and can feel cheap.
Additionally, some surface cleaner companies deliver good customer service whereas others can be a little more difficult to deal with.
Pressure Washer Surface Cleaner FAQs
There are surface cleaners designed for electric pressure washers, gas pressure washers, and both. Gas pressure washers typically work best with surface cleaners with larger diameters whereas electric pressure washers often pair best with smaller-diameter units.
Surface cleaners perform at their best when they are used with pressure washers that match their GPM and PSI range. Before making a purchase, you should be aware of the GPM and PSI of your pressure washer.
Additionally, you should ensure that the attachment can be connected to your pressure washer assembly. The two common connections are a ⅜” and ¼” quick-connect plugs. Some surface cleaners come with both attachment options.
Yes, detergents can be used with some selected models of surface cleaners. Before making a purchase, you should check whether that particular surface cleaner model has a detergent tank attached, or if it can connect with the detergent tank given on your pressure washer.
It depends. Hot water can be used with select surface cleaners but you will have to make sure the one you are considering does. Since most pressure washers use cold water, most surface cleaners do too.
Surface cleaners work best on flat surfaces. Keeping this in mind, you can either use them on a horizontal surface or a vertical surface, as long as it is flat. Just keep in mind that using a surface cleaner on a vertical surface requires much more effort.
Surface cleaners use the same amount of water per minute as your pressure washer does. Now if you factor in that surface cleaners get the job done in much quicker time than regular pressure washer nozzles (up to 8x faster in larger units), you end up saving a lot of water
Since surface cleaners are used to clean surfaces that contain grime, dirt, and debris, and are designed to avoid splashing, some dirt and grime often gets lodged inside it. For example, the bristles around the surface cleaner may collect this debris. So from time to time, you might want to clean the attachment to keep it clean. However, aside from this, surface cleaners do not require much maintenance.
