Best Pressure Washer for an RV

RVs are essential for living in, not just driving. Unlike other vehicles, people use RVs for adventures across the country, especially to campsites. With all that dirt, grime, and dust collected over time, any RV will require deep cleaning that only a pressure washer can do correctly.

What is the best pressure washer for an RV? The best pressure washer for an RV is the Sun Joe SPX3000. This pressure washer makes the top ten list on many automotive sites and is also Amazon’s choice product for pressure washers. It excels above the competition with its tank size, PSI capability, price point, and other unique features. 

Now that you know what the best pressure washer is, it’s time to make sure you have a well-rounded knowledge of pressure washers. You can have the best tool available, but do you know how to use it best?

All About the Sun Joe SPX3000

The Sun Joe SPX3000 has many unique features. Our favorites are:

  • A dual-tank, which allows it to hold up to 1.8 liters of liquid. The two tanks can be filled with the same liquid or split to hold two different types of substances, allowing it to fit any desired cleaning job for an RV. 
  • Total Stop System. This is a mechanism to disable the hose from distributing water whenever the trigger is released. This saves on the cost and usage of water. 
  • Max of 2030 PSI
  • 35-foot cord, helping you easily navigate the entirety of your RV.

Each of these features outdoes its competition, allowing you to move more freely and power wash a bit faster. 

Why the Sun Joe SPX3000?

The Sun Joe SPX3000 pressure washer finds a delicate balance between the more massive duty pressure washers and those that are more lightweight. Each RV will have specific needs that owners will need to be aware of, such as the type of material that comprises the vehicle, such as fiberglass or metal. 

Still, this pressure washer is an excellent match for most RVs and beats its competition by incorporating various qualities that make any pressure washer efficient.

Liquid Storage

Pressure washers need to hold a decent amount of liquid during a wash to avoid constant refills. Not only does the Sun Joe offer that, but it contains two separate tanks leading to a higher hold capacity. When cleaning, multiple liquids are often used, water, and a cleaning agent. With this device, there will be fewer refills needed, and two liquids can be used simultaneously.


Water pressure is vital for any pressure washer to knock off the dirt from an RVs surface quickly. The lighter the pressure, the more the pressure washer may feel like a garden hose. With water pressure that is too low, the dirt will simply become wet, but won’t immediately be knocked away.

Too much pressure could equate more to that of a fire hydrant. But water pressure that is too strong could damage the vehicle, ripping seals, or leak inside of the RV.

The Sun Joe SPX3000 offers a medium output of water pressure to keep the RV safe and ensure cleaning is done correctly, as opposed to damaging the vehicle at all.

Hose Length

Cleaning your RV on all sides, including the roof, will require plenty of space for moving around. Without a hose with a decent length, you will have to move the pressure washer itself more times than wanted. The Sun Joe pressure washer boasts 35-feet, putting in again in a balance of not too long, adding to a heavier weight, but not too short in length either. 

With a hose and structure that are not too large, moving this pressure washer will be easier and won’t require a lot of physical exertion.


The cost of the Sun Joe SPX3000 will find owners at the right balance of finding a product that delivers what you pay for it. As some pressure washers can reach upwards to $300 and more, the Sun Joe SPX3000 is well under that.

Sometimes cheaper products do not have the lifespan of their pricey counterparts. But this pressure washer is tried and true to deliver a long lifespan, especially considering its Total Stop System, which prolongs the machine’s life. 

When paying for a pressure washer, the cost of the pressure washer is essential, but so are the expenses of paying for water and any other cleaning agents used during the process of cleaning your RV. Ultimately, the Sun Joe SPX3000 saves money when you initially buy it, and on all the resources you will conserve.

Why Do I Need a Pressure Washer for My RV?

A pressure washer takes out the physical exertion and time required to clean your RV by hand or with a regular garden hose. RVs can take on a lot of dirt, insects, brush, and other undesired material. If all that dirt and grime is to come off, cleaning by hand will quickly become an arduous task. 

Pressure washers allow RV owners to clean your RV, save water, and ultimately save you money.

The purpose of pressure washing is to rid your RV of dirt and grim on all sides of the vehicle with water delivered at high pressure (PSI). This eliminates the need to wash the vehicle by hand, which would require too much physical labor. 

RVs usually do not fit through your local car wash. They are larger and require more work than the average vehicle to clean.

Pressure washing delivers water pressure that does more in its initial output than hand washing or other washing methods, getting the job done faster.

Since RVs are designed for people to live inside, not just travel short or long distances, RVs are bound to collect more dirt than the average vehicle and incur more wear and tear. Those who experience the occasional bird poop on their car can’t compare their experience to someone with an RV covered in mud and brush on all sides.

Pressure washers allow RV owners to practice self-care for their vehicles, allowing them to take care of their vehicles at a cheaper cost than going to professionals for deep cleaning larger vehicles.

Where To Pressure Wash Your RV

The setting for pressure washing your RV may be just as important as the cleaning method itself. To most efficiently clean your RV and avoid any hazards, you should first park your RV clear of other vehicles and with plenty of space to walk around the vehicle. This means that you will find better results outside than inside.

Ensure that the surrounding area is free of hazards for yourself as you move around the RV while cleaning.

You will be cleaning your vehicle with high-pressure water, meaning when the water hits, it hits hard. As effective as pressure washers are at removing unwanted material from off the surface of your RV, the pressure washer may also remove the wanted items such as the vehicle’s finish, the decals, and water could even potentially leak inside the vehicle through any unnoticed opening.

Additionally, your pressure washer could damage items in your home if you are too close to fragile objects such as windows or other vehicles.

How to Pressure Wash Your RV With the Sun Joe SPX3000

You know that the Sun Joe SPX3000 pressure washer is the best, and now you’re ready. Expect to break down your pressure washing process into parts to maximize your efforts. Freely spraying any and every side is sure to prolong the process. So instead, focus on cleaning specific parts of the RV one at a time.

Here are the general guidelines for figuring out how best to clean your RV. Like other vehicles, not every RV is the same. 

For example, with different types of roofs come different potential problems to watch for, such as accidentally shooting water at something like the AC.

Know Your RV

Some RVs have different types of roofing, including rubber, fiberglass, and metal. Each of these can receive pressure washing. 

But depending on the model of RV you drive, you need to be mindful of what areas you can and cannot spray. In addition to the aforementioned AC example, also be aware of any vulnerable parts of your RV. 

There could be a crack in the body of the vehicle or on the roof that you haven’t noticed yet. There are also areas on the RV that are sealed but can be easily undone with high-pressure water. These areas include the gasket and weather sealants. They’re meant to protect your RV from the elements, such as rain.

Giving your vehicle a look-over before spraying will help you avoid any potential mishaps of getting water into places you don’t want it. Pressure washing without studying your vehicle could easily lead to more damage than the dirt you want to get rid of. This step is crucial in avoiding any mistakes that could ultimately cost you time and money to undo.

Aside from knowing the defects of your RV, it would be wise to read over the RV manual to understand better the type of material your RV is composed of. This is important for pressure washing, but also post-pressure washing.


The next step is ensuring your access to water, a lot of water, before diving into the task at hand. This is very important, especially if this is your first-time pressure washing, you should search for a place to wash your vehicle that gives you infinite access to water and at a fair price. If you can wash your RV at home, then that eliminates the concern.

Some campsites allow owners to wash their vehicles, but this can prove costlier than washing at home.

Setting Up 

Now that you have access to water, set up the Sun Joe SPX3000 pressure washer. Make sure the surrounding area is clear, and you’re good to begin.

The Roof

The best method for pressure washing is starting with the roof of the RV. Depending on the type of RV will determine your specific strategy for tackling the cleaning task. However, most often, the roof is consistently the best place to start. 

When you spray your RV, you want the water to flow down and off your vehicle along with the collected dirt.

Make sure your roof is walkable because that is not the case with every RV. If yours is not, then, if possible, stand in a secure spot where you can safely spray the roof. This will not be as effective as being on the roof but offers some cleaning as opposed to none.

If the roof is not a safe part to clean, then clean the rest with a pressure washer and see a cleaning contractor. In the end, this will require less cost than having the contractor clean the entire vehicle.

The Body and Wheels

When moving to the body of the RV, pressure washing is best done by performing a horizontal swiping motion beginning at the top of the RV. From there, work from top to bottom, completely cleaning the RV and avoiding pushing dirt back onto the vehicle.

Aim the nozzle of the pressure washer steadily, only tagging the areas of the RV that contain the unwanted grime. This will avoid undesirable damage.

Having space around the vehicle allows you to fully utilize the pressure washer without risk of potentially damaging other vehicles or your home if your house parks the RV. After the body of the RV has been managed, aim the nozzle to the tires on the current side.

Spray each side entirely before moving to another side of the vehicle. This saves time and water.

Awnings, Seals, and Other Areas

Awnings are potentially okay to wash depending on the style of awning and the setting of the pressure washer, but avoid pressure washing the other vulnerable parts of the RV. Only wash the significant areas that are secure. Cleaning your RV will make it look good but also increase the lifespan of the RV. 

Here are the vulnerable areas watch for:

  • Select Awnings
  • AC’s
  • Gaskets
  • Seals
  • Decals
  • Cracks in the Rig
  • Windows

A safe principle to follow is if you have doubts about pressure washing a specific area, then hand wash instead.

The Cost of Pressure Washing

Pressure washing will require more time and money to start. Cleaning an RV naturally takes more time than washing a car because of the difference in size. Imagine a tiny home, that’s more equivalent to cleaning an RV.

Given more practice, though, you will become more adept at cleaning your vehicle at a faster speed. You’ll know what to do and how, and in time save money on water. You’ll be saving money by avoiding an over-priced professional cleaner too.

Post-Pressure Washing

To best complement your pressure washing, if the vehicle still doesn’t meet your standards, you may follow up with hand washing or even using cleaning agents. As we know, some RVs are manufactured differently and have designs you will have difficulty reaching with a pressure washer.

Can You Hand Wash?

Of course! But be sure to only hand wash the areas vulnerable to the pressure washer. Handwashing large areas is tiring and time-consuming, so saving this for smaller areas of the RV is important.

Additionally, you want to make sure that whatever tool you use to wash, including the brush, mitts, and any solutions, will not damage your vehicle. Even scrubbing different parts of your RV has the potential to wear off the vehicle’s finish or ruin fabric. Tires can also be damaged if using an inappropriate brush, which can create scratches.

What Cleaning Agents Should I Use?

Just like hand washing, there could be areas of the roof, siding, or wheels, that require more specialized care. If pressure washing and hand washing seem to miss a particular spot, cleaning agents may be useful to get rid of certain spots of dirt. Not every cleaning solution is beneficial for every type of RV. The RV’s exterior will determine which solution you need to use.

Compatible pressure washer cleaners for the Sun Joe include:

Once you’ve had time to experiment with various cleaners, you’ll know which makes your car look and smell the best. More importantly, you’ll determine which cleaner is most cost efficient for you.

Travel Away With Your Clean RV

You are now equipped with the best pressure washer and washing method. Whenever pressure washing falls short of your standards, feel free to follow up with a hand wash. But don’t be afraid to take ownership by cleaning your RV. You will save time and money. Like any vehicle, what you put in is what you get out.

Proper upkeep will see you traveling across the country, making plenty of beautiful adventures and memories. All the while, your RV will not only look clean but will drive just as smoothly.
