The fact that there are 16 individual pressure washer companies out there that choose to use Honda small engines to power their equipment rather than try and build something of their own should tell you everything you need to know about the quality, the capabilities, and the durability of Honda systems.

While it’s pretty tough to get your hands on a Honda powered pressure washer outside of Japan (though not completely impossible) these pieces of equipment have proven themselves to be right up there with the best of the best power washers on the planet today.

The very first under pressure washer wasn’t released to the general public until 1986, almost 50 years after the company was originally established. A number of other small engine projects had been tackled before pressure washers were brought into the product lineup fold, including lawnmowers, snowblowers, and (obviously) motorcycles.

The biggest reason to choose a Honda power washer (or any of the pressure washer brands that are using Honda engine) is because of the durability and reliability of the small engine you will be investing in.

This is a company that has a legendary reputation for high-quality products, for inexpensive products, and for easy to fix and maintain products that fly in the face of most other manufacturers producing small engines today. This reputation is central to the brand image Honda projects and is reason number one to get your hands on this kind of equipment.

What Separates Honda Pressure Washers from the Rest of the Pack

Not only does the legendary reputation for durability separate Honda from the rest of the pack, but the sheer volume of options they make available – options to suit every need and budget – is another major differentiator.

Honda has small engines as small as 25cc and as large as 688cc across their full line of small engine solutions, but the majority of their pressure washer options run from between 160cc to 390cc. The smaller systems are obviously better suited for residential and more casual applications with the larger options perfect for commercial setup, and there are some “tweener” solutions that fit right in the middle as well.

The inclusion of aluminum cylinder sleeves or cast-iron sleeves (depending on whether you choose a residential model or a commercial model, respectively) improves durability significantly. Most all Honda pressure washers also include automatic low oil detection systems to warn you ahead of a catastrophe, and fuel shut off valves are included on all of the GX (commercial) options as well.

Honda prices have certainly crept up a little bit in years past compared to where they used to be previously, but this has a lot to do with their refusal to cut corners when it comes to construction materials or engineering.

Most still agree that Honda represents maybe the best investment in the pressure washer world, if only because the “heartbeat” of any pressure washer system – the small engine – is going to last you a lifetime and then some with very little maintenance.

Resale value on these kinds of pressure washers is also through the roof because of the longevity and durability they bring to the table. If you ever have to sell your unit when you’re done using it you’ll be able to recoup most of your investment, even if it’s a couple of years old.

Whether for serious cleaning at home or on a trade site, it’s hard to go past a pressure washer powered by a Honda engine. With best in class performance backed by decades of reliability and a huge service agent network, a Honda pressure washer blows away the competition.

But how do you know which Honda pressure washer to choose?

Honda pressure washers blow away the competition when it comes to serious domestic applications or commercial cleaning requirements.

Before you start comparing features, there’s one crucial thing to check: make sure the brand you opt for is using a genuine Honda Australia approved engine. Not an import or a fake. There are plenty of impostors out there (affectionately known as a ‘Chonda’) which are just copies or grey imports. Part of the reason you pay good money for a Honda is not only the engine’s performance, but the service agent support network you get – if its not a genuine Honda, it won’t be backed by authorised service agents for spare parts or warranty support.

Next, work out what you’ll be using the Honda pressure washer for most of the time. This will help you prioritise the right features.

To help, take a look at our pick of the best Honda pressure washers for different tasks:

What You Need to Know Before Buying a Pressure Washer

pressure washer buying guide

Pressure washers have come a long way. Over the last ten years the quality has increased as prices have become more affordable. The cleaning ability of a pressure washer is great, removing dirt, grime, and algae quickly, efficiently and effectively. A pressure washer can greatly increase your ability to maintain and clean your property and equipment giving it greater value. If your time is valuable, a pressure washer could be a good investment, but if you get the wrong machine, you will be frustrated and you could waste a lot of time and money.

The goal of this buying guide is to help you understand what a pressure washer does and what you need to look for when deciding to purchase one. If you’re ready to start shopping, check out the pressure washers at Or keep reading to learn more about the following:

How a Pressure Washer Works

A pressure washer is actually a fairly simple piece of equipment. A motor or engine turns a pump, pushing water through an orifice (tip). The water accelerates as it goes through the small hole, much like a river flows faster in a narrow gorge, and that fast-moving water is very useful for blasting dirt and grime. The math is quite simple. Each time the pump turns over, a specific volume of water is pushed through the tip. The more water you push through the tip, the more pressure is developed, and therefore more power is required. The higher the pressure, the faster the water moves, and the harder it hits the dirt, removing it from the surface you want to clean.

What to Consider

The two most important considerations when buying a pressure washer are size, which determines how long it takes to do the job or how many jobs you can do in a day; and life expectancy, which determines how many hours of work you can do per dollar spent during the life of the machine.

Understanding Ratings

Here are some basic ratings:

Horse Power (HP)

This is how much power the engine or motor produces. This rating is important because it directly relates to how much pressure and volume the pump can produce.

Pounds Per Square Inch (PSI)

The pressure generated by a pressure washer is measured in pounds per square inch or PSI. Pressure contributes to the cleaning force.

Gallons Per Minute (GPM)

The water volume produced by a pressure washer is measured in gallons per minute or GPM. Volume also contributes to the cleaning force.

Cleaning Power Units (CPU)

Cleaning Power Units quantifies a pressure washer’s cleaning ability. To determine CPU, multiply GPM x PSI. The greater the CPU, the greater the ability the machine has for cleaning deeply and effectively.

Often consumers are so focused on the PSI rating of the machine, they do not consider the CPU. For example, a pressure washer may have a rating of 2,800 PSI and 2 GPM, giving it a CPU of 5,600. Another pressure washer is rated for 2,400 PSI and 4 GPM. That’s a CPU rating of 9,600. In this example the lower PSI machine has more than 40% greater cleaning power than the higher PSI machine. The result is that the 2,400 PSI machine will be able to clean an area 40% faster than the 2,800 PSI machine.

Now consider this: A garden hose typically provides 6 GPM at 10 PSI giving it 60 CPU. With a standard spray nozzle attached to the garden hose you can get around 5 GPM at about 40 PSI generating 200 CPU. We all have seen the difference of how much more effective a simple spray nozzle is at cleaning dirt off surfaces. Trying to clean your driveway with your garden hose spray nozzle generating 200 CPU is fairly ineffective. However, if we take a mid-range pressure washer rated at 2.0 GPM and 2,500 PSI (5,000 CPU), the CPU rating represents a staggering 25 times increase over a typical garden hose spray nozzle.

A commercial pressure washer rated at 4 GPM and 4,000 PSI is an incredible 16,000 CPU. It is not difficult to see the difference in efficiency. However, this is all true within a range. If you have extremely high pressure and low volume, you can cut steel or concrete (water jet cutter), and if you have extremely high volume and low pressure, you have a river. Neither of these would be very good for cleaning your house or driveway.

Pressure washer pumps have pistons and valves similar to a gas engine or an air compressor. On some pumps the pistons are driven by a wobble plate. On others, the pistons are driven by a crankshaft. Crankshaft-driven pumps are generally built better and will last longer.

Pressure Washer Pumps

This is the part of the pressure washer that receives water from your hose, and pumps it through a tip at high pressure. There are several common types of pumps that you will see in commercial and home-owner type machines. All pressure washer pumps have pistons and valves similar to a gas engine or an air compressor. On some pumps the pistons are driven by a plate on an angle (wobble plate), and in other cases the pistons are driven by a crankshaft. Crankshaft driven pumps are generally built better and will last longer.

Pressure washer pumps are equipped with bypass valves, so that when you let go of the trigger, or when the tip gets plugged, the water will bypass and go back to the inlet side of the pump. If left in this mode for longer than the manufacturer recommends, the water will get hot and cause damage to the pump. On a gas-powered pressure washer, the pump includes a thermal relief valve that dumps hot water into the bypass loop. Most bypass valves are adjustable so you can dial down the pressure when cleaning sensitive materials

Low-cost pressure washers have pumps with very low life expectancies—some as low as 60 – 100 hours. When buying a pressure washer, make sure you find out the life expectancy of the pump. If the information is unavailable, stay clear because it is very likely that the manufacturer does not want you to know how low it is.

Another very important factor to consider is parts availability. KMS Tools was a warranty/service centre for some low end brands, however lack of parts availability and unreliability of these machines were such a problem that we decided to no longer provide this service.

Before buying your machine, ask where you can get parts if you need them. KMS is often referred to by other retailers as a source for parts and repairs for numerous brands that are pretty much disposable. If you are buying a new machine for $200.00 or less, expect it to be a disposable machine that might last you only one season, and be prepared to spend a lot of time to get the job done.

Direct Drive or Belt Drive

The drive describes how the motor is connected to the pump. Direct-drive systems are most common. The pump is bolted directly to the motor or engine with a shaft coupler. Compared to a belt-drive system, direct drive requires fewer parts and space, resulting in a more compact design. Direct drive is also considerably more economical than an equivalently rated belt-drive machine.

Belt-drive systems are typically seen on industrial platforms. The pump on a belt-drive unit turns at a much slower speed. The belt absorbs vibration that would wear out a unit faster. Since the pump turns at a lower speed all the pistons and valves in the pump are larger. All this adds up to a cooler running machine that will last considerably longer than an equivalent direct drive version. However, there is slightly more maintenance and considerably more dollars involved (10 – 30% more). If you are using your pressure washer on the job, then you want to consider buying a belt-drive machine. However, an equivalent direct-drive machine will have the same performance for a lot less money.

Gas Engine or Electric Motor

On a pressure washer, the engine or motor powers the pump. The more powerful the engine or motor (rated in HP), the greater the PSI and GPM the pump produces. Gas engines are typically designed to last between 300 and 3,000 hours. The motors on electric pressure washers usually last longer than the pumps.

Electric Motors

Electric motors are very low maintenance and fairly quiet. There is also no exhaust so they can be operated indoors or in poorly ventilated areas. A typical electric pressure washer that is 115 Volt and 15 Amps will be fairly light duty because it is built for the low-price market. The motor is not strong enough to generate much pressure or volume. While electric pressure washers are compact and usually portable, most jobs take longer with a light-duty electric pressure washer.

HP is rated differently on electric motors compared to gas engines. A typical low-price electric pressure washer is rated around 1 to 1-1/2 HP and would be equivalent to a 3 HP gas pressure washer. (Electric motor HP has to be doubled to equal gas engine HP.)

Heavy-duty electric pressure washers are available for applications where power is available and portability isn’t a factor, and exhaust from a gas engine would be a problem.

Gas Engines

Gas pressure washers are larger and heavier and mounted on a cart with wheels. Some are better balanced and easier to maneuver. Gas engines can produce more power and are a lot more mobile as they do not need to be plugged in to an electric power source. Since gas engines can be more powerful, the pump can generate considerably more PSI and GPM so that they can clean faster and deeper than any 115 Volt rated electric pressure washer could. However they do take a little more maintenance and cost more to operate. They must be used in well-ventilated areas because of the emission of carbon-monoxide fumes.

Pressure Washer Accessories

Without accessories, your pressure washer is fairly useless. It would be like having a drill without any drill bits.

Pressure Washer Hoses

You probably want a 50 ft length hose. If you go shorter, you will have to keep moving your machine. Make sure you get a quality hose with the proper PSI rating to match your machine. A poor quality hose will break down faster, is more susceptible to leaks and kinks, and will usually be less flexible and harder to work with.

Pressure Washer Wands and Tips

The wand includes a handle with a trigger valve, and different lengths and angles of wands are available for different applications. You can change the spray pattern by changing the tip at the end of the wand. Most pressure washers come with a selection of tips—from a very narrow spray to generate higher force at the tip for deeper cleaning to a wider spray that has less force but covers more area. Most tip sets also include a low pressure tip for applying cleaning solutions.

In addition to tips, other, very useful attachments are available:

Dirt Blasters

A dirt blaster or rotary nozzle attaches to the end of your wand. It has a very narrow spray that spins in a circular motion very rapidly. Dirt blasters are effective because they can quickly clean hard surfaces very well and, when used properly, avoids the tiger striping effect on your driveway that happens with conventional spray tips.

Extension/Telescoping Wands

For cleaning out-of-reach areas, look for an extension wand that’s adjustable up to 24 feet in some cases. Extension and telescoping wands are beneficial if you need to reach up high. They can save you from trying to pressure wash while standing on a ladder.

Gutter Cleaners

A gutter cleaner is a simple hooked extension that affixes to the end of your wand. It lets you get into your gutters to clean them out.


A Whirl-A-Way is an accessory that looks a little like a lawn mower and has two rotating nozzles inside. They are available in sizes from 12” to 24” and excel at cleaning large flat areas.

Hot Water Pressure Washers

Hot water pressure washers are commercial machines with built-in water heaters. The cleaning effect of the machines is considerably better than a cold water machine with comparable PSI and GPM because hot water simply cleans more effectively than cold water. Hot water pressure washers break down and remove dirt and grime faster than cold water pressure washers, and often eliminate the need for expensive chemicals. Do not feed hot water into a normal cold water pressure washer pump. The heat will damage seals and o-rings.


Detergents can greatly increase the speed of cleaning and help remove tough stains. Most pressure washers come equipped with a venturi tube that will draw in the detergent from a bottle or pail and add it to the water stream. The detergent should be first applied with a low pressure spray, given some time to do its work to break down the dirt, and then washed off with a normal high pressure spray.

Choosing the Right Pressure Washer

When it comes right down to it, you need to buy a pressure washer that fits your application. There are many different types of pressure washers—from very low-end machines to extremely powerful industrial machines. Before you buy a machine you need to sit down and ask yourself these questions:

  • “How will I use a pressure washer?”
  • “How often will I use a pressure washer?”

If you are a home owner, you will probably use a pressure washer less than 50 hours per year. In this case getting a machine rated for 500 hours will last you up to 10 years if properly maintained. However, if you are using it on the job, you will want something rated for 2,000 hours or more. If time is important to you, buy as big a pressure washer as you can justify. A 13 HP gas pressure washer will clean your driveway about 10 times faster than a small electric unit. It will also last longer because it doesn’t have to run nearly as long to do the job. Finally, plan in advance what attachments you will want in the future and make sure that the pressure washer you buy has enough power to support them.
