Wilks Genuine USA TX750i Petrol Pressure Washer Review
Wilks Genuine brand is rapidly gaining popularity as a reliable and trustworthy brand. It’s proven its dependability and tough cleaning power to many reviewers. This is a great choice if you’re looking for the best petrol pressure washer on the market – not least due to its power.
This TX750i model pushes out 272 bars of pressure – the most powerful of the washers I reviewed – and processes 660 L of water per hour. That’s more than enough pressure and water to deep clean the muddiest of patios, animal cages or building sites from any water source.
It can draw water from a tap if you have one nearby, but also a bucket or pond if you’re using it elsewhere. This really makes it a truly versatile pressure washer.
The engine is a 210cc 4-stroke OHV and it churns out a massive 8 horsepower. Imagine – the power of 8 horses coming from your pressure washer! It’s a powerful machine for sure but still runs relatively economically on unleaded petrol.
The hose length is a big bonus; it comes with a 30 m hose in total. It’s made up of two separate hoses: a 20 m one and a 10 m one, so you can connect them together or use them separately. They all fit neatly onto the frame along with the nozzle accessories and 6 L detergent tank.
Accessories include: two different lances with five colour-coded nozzles for fuss-free changing – the colour coding is a great touch as it stops you putting on the wrong nozzle and damaging the paint on your car.
This petrol pressure washer has 30 cm wheels that are robust enough to take the machine over bumpy, uneven and wet ground with ease.
I highly recommend this piece of kit for tough jobs in the great outdoors.
Briggs & Stratton ELITE 3200Q Petrol Pressure Washer Review
The Briggs and Stratton Elite is one of the best petrol pressure washers on the market because it’s powerful, with a high water flow, and extremely quiet to run.
This petrol pressure washer really is the business. If you need something portable that can blast away the toughest of muck then this is for you. Let’s look at the basics first:
Max bar pressure is 220 – that’s more than you’ll get from an electric pressure washer – and its pulls through a massive 612 L of water per hour. This is achieved thanks to its ‘annovi reverberi’ pump (that’s Latin for maximum reliability – Briggs and Stratton’s words, not mine!). Everything is powered by Briggs and Stratton’s CR950 190 cc engine which has an easy-start system which needs no priming or choke.
Included is a quick-connect spray system with a variety of angled hose heads ranging from 0-degree through to 40-degree angles. Plus there is a soap spray head for using with detergent.
You’d think with all that power you’d need ear defenders but this elite petrol pressure washer has a lo-tone muffler to bring the noise down by 40% when the trigger gun is used.
Briggs and Stratton are a reliable company who have a lot of customer service on hand to help if you need it. You probably won’t ever need them, seeing as it’s a reliable, quality machine, but it’s nice to know for peace of mine.

A few things I loved about this pressure washer; first, it’s fantastic quality. It comes with a full metal high pressure pump, and the finned engine housing helps alleviate heat build up so you can work for longer.

Waspper Petrol Pressure Washer Review
Waspper’s W3000HA petrol pressure washer makes some bold claims – specifically that it’ll last 5 x longer than conventional pressure washers – so what makes it so special?
It boasts 220 bars of pressure run by a 196 cc Peggas engine. Peggas engines are top quality machines known for reliability – plus this one has a finned engine to keep it cool.
Most of the body parts are made from long-lasting rust-resistant metal. The pump and head are aluminium, the spray gun is metal, and the 40 cm lance is stainless steel – this all makes for a pretty sturdy machine, no more bits breaking off when it bumps over rough ground.
Its water flow rate is 8.5 L per minute which equated to 510 L per hour. This is plenty to hose down large areas, even if they have embedded staining.
There are three different nozzles which have M22 connectors to make changing them over speedy and fuss-free. You’ll be especially glad of this on cold days when your hands are cold! They all clip onto the pressure washer’s main body.

Things to Know Before Buying a Petrol Pressure Washer
Pressure washers are fantastic. I imagine we’ve all at least heard about the amazingly satisfying results they can so easily deliver.
They can remove layers of caked-on grime, or get the car shining like new, with very little effort.
Petrol pressure washers are extremely powerful, generally more so than electric versions. So, if you’ve got some serious pressure washing to do – these models are going to be your friends!
There are a few considerations to bear in mind when choosing the best petrol pressure washer for your situation, so take a look at the tips below to help you make an informed decision:
Whilst electric pressure washers are certainly useful pieces of kit in the home environment, petrol-powered pressure washers hold a number of advantages.
The greatest advantage is that petrol-powered machines are fully portable. Unlike a mains-powered electric model you don’t need a power socket, just petrol and oil. This can be a huge benefit if you’re trying to clean something away from the house or shed.
You’ll also find they are more powerful than electric models. Even the petrol-powered machines with the lowest available bar pressure will top electric ones. That gives more power and water flow to get the job done quickly
That said, petrol models are noisier than electric machines so you may have to be considerate about what time of day you use it. Petrol pressure washers also emit fumes so they are not considered to be as environmentally friendly as electric ones.
The way petrol pressure washers work is the engines power the water pump. The water pump is in charge of building up the water pressure. So, the more engine power, the higher your bar pressure can climb.
A bigger engine will require more fuel, so you should probably look for an engine which is just enough to get your jobs done, but isn’t excessively more powerful for no reason. Otherwise you may find that you’re spending more money on petrol than necessary.
Water pressure is important – it’s what shifts the filth.
Petrol pressure washers usually have a higher water pressure than electric machines.
You need a lot of power to get cleaning jobs done spotlessly and quickly. These washers are therefore particularly useful if you’re trying to shift a lot of grime from concrete or paving and don’t want to spend a lot of time on the job.
For cleaning your car, you want a pressure washer which can deliver around 110 – 180 bars. You should be mindful of using too powerful a pressure washer as it could damage the paintwork.
More water flowing through your machine means cleaning jobs are completed faster.
Petrol-powered pressure washers often have a higher flow rate, but there is some overlap between the high-end electric models and the budget petrol machines.
The higher the flow rate the faster the job. Look for at least 360 L per hour for a home environment. For commercial purposes, Briggs & Stratton Pressure Washer with 660 litres per hour flow rate, is the best option.
Some petrol pressure washers come with an in-built detergent system. It’s not a deal breaker, but it’s certainly something you might want to look out for to make your life easier. If you’re keen to use detergent when doing your cleaning jobs – particularly if you’re targeting mould and don’t want it spreading, this is made all the more easy if the unit has a detergent tank. If not, you can always try squirting detergent from a spray bottle directly to the surface – this isn’t always a lot of fun when you have cold, wet hands.
It’s great when pressure washers come with a range of nozzles. These can help you complete specific jobs. Angled spray heads are great for cleaning under wheel arches and getting into guttering. The more options you have, the easier you’ll find a wide range of cleaning jobs.
Petrol pressure washers come with big wheels and a sturdy frame so you can move them around easily.
Look for rubber wheels as they protect the engine and pump from uneven ground. 25 cm+ wheels are best.
Also keep an eye on how the hosepipe and accessories are stored. It’s a pain trekking out to an animal pen or fence if you need to carry a second bag stuffed with the lance, hose, and accessories as well as the washer itself.
The best petrol pressure washers have onboard storage that makes them easy to manoeuvre.
Top of the range petrol pressure washers are usually tough, durable pieces of kit because they are dragged over rough ground and used in commercial environments.
That said, you should always look for a long warranty as the machines are used roughly and pieces can break no matter how careful you are – especially the hosepipe.
Good makes often have long warranties. If the warranty is short or doesn’t exist at all, think twice.
Petrol Pressure Washer FAQs
The water (and detergent if you’re using it) flow into the hose. Water is supplied either from a tap, garden hose, or water source like a bucket. The petrol engine powers the water pump, drawing the water in until it reaches the required bar pressure and then it fires out of the high-pressure hose.
The concentrated area of high-pressure water knocks grime and stains away from the surface using about 80% less water than a standard hose pipe.
Using a petrol pressure washer is a bit more complicated than simply plugging it into the mains Here’s a quick guide:
- Remove the oil dipstick and fill it up to the line with the correct oil (look in the user manual)
- Unscrew the petrol cap and fill the tank with the correct fuel e.g. unleaded petrol
- Connect the hose to the water tap/water butt/bucket
- Attach the high-pressure hose to the spray gun
- Take the other end of the high-pressure hose and attach it to the pump water outlet
- Turn the water source on
- Turn the engine on
- Turn the fuel valve on
- Apply the choke if necessary
- Pull the starter cord
- When the engine is running smoothly, it’s time to turn off the choke. Give the hosepipe 30 seconds to run clear so any particles in the pipe flow free. Then start cleaning!
You should regularly check to ensure the fuel and oil tanks are not running dry. Turn off the machine completely before you fill them up.
Yes. For this reason, you need to make sure that you are not using too high a pressure or too forceful a jet. For example, you can damage concrete by using too much pressure. To avoid damaging surfaces as much as possible, follow these steps:
- Make sure you’re using the right nozzle for the job
- Don’t use excessive pressure when it’s not necessary
- Don’t spray too close to the surface
- Don’t angle the spray on one spot for too long
