Wilks Genuine USA TX750i Petrol Pressure Washer Review
Wilks Genuine brand is rapidly gaining popularity as it’s proven its reliability 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.
The Wilks pushes out 272 bar of pressure, that’s the most out of all my reviews, and processes 660 litres of water per hour – more than enough to deep clean the muddiest of patios, animal cages or building sites from any water source.
The engine is a 4-stroke OHV 210cc and it racks up 8 horsepower. It’s a powerful machine for sure but still runs economically on unleaded petrol because it’s a pain having to refill all the time.
There’s a high pressure 30 metre hose made up of 20 metres plus an extra 10 metres that all fit onto the frame neatly along with the accessories and six-litre detergent tank.
Accessories include two different lances with five colour-coded nozzles for an easy no fuss changeover – this 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 12-inch wheels that are man 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.

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 has 220 bar of pressure run by a 196cc 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 – no more snapping bits off when the machine bumps over rough ground.
Its water flow rate is 8.5 litres per minute which is 510 litres per hour and plenty to hose down large areas that have ground-in staining.
There are three different nozzles with quick couple M22 connectors for speedy no-fuss changeovers when your hands are freezing, and they all clip onto the pressure washer’s main body.
Waspper’s petrol pressure washer has a two year guarantee and its made in the EU. It’s well worth considering if top-of-the-range build quality and long-lasting machines are your preference or you’re looking for the best commercial petrol pressure washer.

Parker Brand Petrol Pressure Washer Review
Parker Brand’s petrol washer is the best petrol pressure washer for the money. It’ll save you a packet and still clean those grimy ‘out-of-power-cable-reach’ areas.
This budget machine has a 6.5 horsepower engine on an air-cooled open design frame. Its 208cc of power gives you 213 bar of pressure which is pretty high and certainly enough to deep clean really grimy caked-on dirt.
The hose measures eight metres long and it is wire reinforced for those tougher outside jobs.
It has vibration reduction on Parker’s previous model to reduce noise levels, and a frontal integrated detergent tank which is a nice touch if you’ve ever struggled to reach detergent tanks unhelpfully placed behind the engine and hosepipe connectors.
In terms of accessories, you get five colour-coded nozzles that alter the jet spray and a specialised soap nozzle.
This isn’t the best commercial petrol pressure washer, but it’s certainly powerful enough for the home environment and for the price you won’t find better.

The Briggs and Stratton Elite is one of the best petrol pressure washers on the market because it’s powerful, has high water flow, and it’s the quietest around.
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 660 litres of water per hour with an annovi reverberi pump (that’s latin for maximum reliability). This is all powered by Briggs and Stratton’s CR950 190cc engine with easy start system that needs no priming or choke.
Included is a quick-connect spray system with a variety of tips ranging from 0 degrees through to 40-degree angles, and a soap spray tip for the detergent injection system.

There’s a long guarantee on this quality petrol pressure washer and it’s backed by the dealer network. If you have a problem just call them up. This is certainly one of the best commercial petrol pressure washers on the market today.

Petrol Pressure Washer Buyer’s Guide
Benefits of Petrol over Electric
Whilst electric pressure washers are useful pieces of kit in the home environment, petrol powered pressure washers hold advantages.
The greatest advantage is that they are fully portable because you don’t need a power socket, just petrol and oil.
You’ll also find they are more powerful. Even the lowest bar petrol powered machines top electric ones and that gives more power and water flow to get the job done quickly
What Engine Power Is Best?
Engines power the water pump that builds up water pressure, so the higher it is the higher your bar pressure can climb.
What About Water Pressure?
Water pressure is important – its what shifts the filth.
Petrol pressure washers usually have a higher bar rating than electric machines. For deep cleaning or commercial jobs, look for pressure washers with minimum of 220 bar like the Wilks Genuine brand or the Waspper Petrol Pressure Washer. You need a lot of power to get cleaning jobs done spotlessly and quickly.
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 litres for a home environment. For commercial purposes, Briggs & Stratton Pressure Washer with 660 litres per hour flow rate, is the best option
Do I Need a Detergent System?
No, but an onboard detergent tank is a lifesaver, especially in cold weather!
Squirting detergent from a spray bottle when you have cold, wet hands is no fun. A detergent system that automatically applies detergent through a specific attachment is worth having.
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. 10 inch plus 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 fenceline if you have a second bag stuffed with the lance, hose, and accessories in one hand.
The best petrol pressure washers have onboard storage that makes them easy to manoeuvre.
Are Warranties Important?
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 like my recommended best petrol pressure washers all have long warranties. If the warranty is short or doesn’t exist at all, think twice.
How does a petrol pressure washer work?
They work in the same way as an electric pressure washer. The water (and detergent if you’re using it) flow into the hose. 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.
How to use and refill a petrol pressure washer?
Using a petrol pressure washer is a bit more complicated than 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 its time to turn off the choke and start cleaning. Give the hosepipe 30 seconds to run clear so any particles in the pipe flow free.
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.
