Best Petrol Pressure Washers in UK (2023) Expert Review
A petrol pressure washer has enough power to take care of the toughest stains. Find out what you should look for before buying and which models I recommend.
I remember a few summers ago staring out of my back window at my old, dirty deck. There were stains all over it giving it a grey, aged look. I knew it was time to power clean it and get it looking like new again. I also had some old paint stains on my sidewalk that needed to be cleaned up. With the paint stains and a large deck I knew I needed a powerful petrol pressure washer. So I started researching and here’s what I found out.
How do Petrol Pressure Washers Work?
If you are looking into pressure washers, you already know that using a pressure washer is the best way to get something clean fast, but that does not mean you have ever used a petrol pressure washer yourself. Before you take on the project with this powerful machine, make sure you understand how it works. Keep in mind that different pressure washers work in different ways so you will want to adjust these instructions according to the model you have chosen. I always recommend reading the instructions manual before you start.
Most pressure washers have a stream that is 50 times more powerful than the average garden hose. But because the water is pressurized and comes out through a small hole, you are actually using less water than you would with your regular garden hose.
When you start your petrol pressure washer, the water pump inside will start the pistons. The fresh water that comes in through the garden hose you have hooked up to the machine will enter the water tank just off to the side of the engine. The water pump will then pressurize the water and drive it up the hose that is attached to your spray gun. Then you pull the trigger and fire away at that dirty surface.

Types of Pressure Washers
If you have ever encountered a tough cleaning project, you might think about using or even purchasing a power washer. The hard part about choosing the right machine is that not all models are created equal. You cannot simply go out and buy the cheapest washer you can find. There are actually two different types of engines associated with power scrubber systems: petrol and electric.
If you are considering a petrol machine, there are advantages and disadvantages of these models:
If you decide on a petrol pressure washer, you will also want to keep in mind that there are two different types of petrol-powered engines – the Side Valve and the Overhead Valve. The side valve is also known as the L-head. This type of engine has been around for 60 years and is quite cheap for manufacturers to create. The running life of the engine, however, shows that the manufacturing is cheap because the engine is prone to have quite a few different problems. The overhead valve engine, also known as the OHV is the best type of engine. Petrol pressure washer models with this type of engine have more power and make less noise. They also use less petrol and have a longer life span that includes energy efficiency.
Safety Tips
In order to stay safe when you are using a petrol pressure washer, you will need to use some common sense.
- Be sure never to aim the sprayer at another person or an animal because the pressure is high and could cause injuries.
- Read through your manual and make sure you understand how your petrol pressure washer works.
- Since you are using water, keep your petrol pressure washer away from electricity sources.
- Make sure you understand how far away you need to be from the surface you are cleaning. Standing too close can destroy the area, especially something like soft wood siding, and possibly cause harm to you.
- Use the proper cleaning chemicals and not bleach. Using the wrong chemicals can damage the washer and the surface you are trying to clean.
- Adhere to the safety check list that comes along with the washer.
- Wear protective eye gear and check the washer’s connections before you turn it on every time.
- Clean from the ground, instead of a ladder, when possible to avoid falls and unstable footing.
The Ultimate Guide to selecting the Best Pressure Washer
Here are some important things to know before you choose a pressure washer. Learn about psi, gpm, and find out whether petrol or electric power cleaners are better.
If you’re like me, you like to try to do something yourself before you just hire somebody. This is especially true around the house. I’m not what you call an extreme do-it-yourselfer trying to tackle complex electrical wiring or putting up solar panels for example, but I do feel that I can handle some of the easier things, like power washing my deck.
Now I’ve got a pretty big deck on my house, it’s about 400 square feet, so I wanted something that was going to get the job done fast. The last thing I want to do is to have to speed 3 or 4 weekends in a row cleaning my deck and walkway every summer. We all have better things to do with our free time.
So I set out to find the best high psi cleaner engine that will work the fastest and get the job done without damaging my deck. Surprisingly I found out that PSI (pounds per square inch) is not the most important factor you should be looking at. Here is what you need to know when choosing a pressure washer.
How much power a washer can produce?
Intensity scrubbing apparatus are fantastic for speed cleaning your car, bikes, lawn furniture, deck, siding, driveway and walkways. Many are even powerful enough to peal paint. Even the cheapest electric models will deliver at least 20 times the pressure of your standard garden hose and use about 20% less water to clean the same area. And you can save a ton of time as well, especially if you’ve been cleaning with a scrub brush in the past. There are three important measures that determine how effective washers are at cleaning a particular surface.
When looking for a high pounds per square inch cleaner apparatus, it’s better to go for a bit more psi than you think you might need. This means you’ll have enough power to take care of tough stains and you won’t have to run your machine at full blast which can wear it down quicker.
Here is a general psi range usage breakdown:
- 1,000 to 1,500 psi – This range is perfect for washing your lawn furniture, cleaning cars and bikes, and garden tools.
- 1,500 to 2,000 psi – You can use washers at this power level for cleaning the muck off your patio or small deck and washing the siding on your home. This level will take off some easy stains but for tougher stains and mold and mildew on decks that have not been cleaned in a couple years, you’ll need a bit more power.
- 2,000 to 3,000 psi – This pressure level is perfect for large areas like a big deck, walkway, or driveway. You can also clean your home’s siding using the proper safety measures to protect the wood.
- 3,000 to 4,000 psi – You’ll be able to strip paint at this power level and clean stained concrete. Machines that have this psi level are very, very powerful and you should be careful using them.
Hot water or Cold?
All consumer power washers on the market for residential purposes use cold water. That is what I cover on this site. Hot water over 104 degrees Fahrenheit will damage the pump and cause leaks in most residential pressure washers. If you have a tough job like the removal of grease and oil then you’ll need to use detergent and a machine that blasts hot water. In this case I would recommend renting one or hiring a power washing company to come out and take care of the job.
Pressure Washing Terminology
So, let’s take my deck as an example, 400 square feet, and use the lower numbers of 5 and 8 square feet per minute. Using the lower 2 gpm washer, it would take me about 80 minutes (400/5) to pressure clean my deck. On a side note, it usually takes me much longer than this, because I add cleaning solution and like to go slow over trouble spots. Using the stronger 3 gpm model I would be able to get done in 50 minutes (400/8), saving myself 30 minutes each time I clean my deck. In my opinion, that’s worth upgrading especially if the price difference between the 2 and 3 gpm models is not too steep.
Now that you understand how power is measured and have a better idea of what type of washer you need to get the job done, you can start looking at engines. Pressure washers are powered by either a petrol powered engine or an electric engine.
Picking a Petrol Powered Max PSI Cleansing Mechanism
Petrol powered machines are able to generate a lot of power, up to 100 times as much power as your garden hose, which can deliver about 40 psi. You can use petrol machines to clean large decks, the outside of your house, your driveway and sidewalk, and even to strip paint if you get one with enough power (usually greater than 3,000 psi).
You have to be careful when you use petrol powered washers though because they are so powerful. You can damage the siding on your home and splinter the wood on your deck if you don’t use the right spray setting. Soft wood siding like cedar is especially vulnerable to damage as are areas where you’ve caulked. You need to make sure you have the nozzle set at a wide enough setting to get the job done quickly and not damage the surface you’re cleaning. A 20 degree setting usually does the trick.
Choosing an Electric Pressure Cleaner
Electric models are very popular with homeowners and can be used to clean a variety of different things including small decks, cars, and lawn furniture. They are cheaper and less expensive to operate that petrol powered models and they are better for the environment because they do not emit fumes. You’ll need to plug these units into an outlet so you’ll need to have an extension cord. Also some models will require a 20 amp circuit and a special extension cord.
When you shut off the spray by releasing the trigger, most electric units will stop running, so the noise goes to zero and you save on electricity. Manufacturers refer to this as “total stop system or total stop trigger gun.” Some units have a timer setting where the unit will only shut off after a certain number of minutes. So if you take a short break of two to five minutes the unit shuts off. The motor on a petrol unit will continue to run even when the spray nozzle is not being used.
Many electric models will also come with two built in cleaning tanks. This means that with a turn of a knob you can go from washing your car to power washing your deck and using two different sets of cleaning solution for each specific task.
Which is better Petrol or Electric?
This depends on how you plan on using the machine. As you can see from the grid below, if you plan on heavy uses like power cleaning your large deck and cleaning the siding on your home every year, then you definitely want to go with a petrol unit. If you think you’ll just be using your washer for some lawn furniture, your car, and a small deck, then an electric model will be just fine.
Also if you’re a contractor or plan on using your pressure washer for commercial purposes, then you also definitely want to go with a petrol powered model. Consumer Reports Magazine recently conducted comparison testing between petrol and electric powered models and they found that petrol models are ten times faster at stripping paint off vinyl siding. They used the paint test to simulate deep, hard stains like tree sap.
| Petrol | Electric | |
|---|---|---|
| PSI Range | 2,500 – 4,000 | 1,300 – 2,000 |
| Best Uses | Cleaning large decks, siding, and large areas, removing tough stains. | Cleaning patios and small decks, outdoor furniture, cars, boats, grills. |
| Sound Levels | 85 decibels (dBA) | 78 dBA |
| Price Ranges | £400-1000 | £120-250 |
| Pros | Nearly twice as powerful as electric and can clean the same area three times as fast. Many spray and nozzle options to choose from. | Light, quiet, easy to maintain, have no exhaust emissions. Easy to start and stop and can be stored indoors. Many models shut off automatically. |
| Cons | Heavy and noisy. Pull start. More maintenance overall than electric models. Need tune ups and must be winterized with anti-freeze in cold climates. Extra power means you need to be more cautious as wood and other surfaces can be damaged or you could be injured. | Not as powerful as petrol, which means slower cleaning. Need to be near an outlet or have a long extension cord to use. Wands and nozzles are not as sturdy as those that come with a petrol powered model. |
