If you wanted a bit of advise from a professional in the pressure washing industry we asked Ryan from Kirbside Cleaning for his tips on buying a petrol pressure washer. He said “I started my business using the Wilks USA – TX750i and I think it was crazy that you can buy this thing from Amazon. Its powerful, easy to control and comes with loads of extras and never skipped a beat whilst I was using it!”

As with any proper bit of kit, the price is dependant on what you get but we have made sure that these options are the best pressure washers suitable for the job at hand!

The best petrol pressure washer can clean decking, prepare walls for painting, graffiti removal, clean swimming pools, and clean garden furniture.

You can also get cordless pressure washers which are great for cleaning home furniture, bikes, and bins.

With the Petrol Pressure washer market expanding all the time and new products coming to market there’s one company that stays consistent with its high-quality TX750i. It includes an extra 20 meters of as well as a gutter cleaner over its younger brother, the TX750. Its also 10kg heavier, weighing in at 40kg.

Any Wilks-USA unit is going to be a great choice for you as they are built from quality material and made to last.

The TX750 & 750i both come with a very fuel-efficient 8 horsepower, 210cc, four stroke petrol engine, OHV (overhead valve) petrol engine and are decorated in a lovely looking yellow and black design. The TX750i is 65 x 41 x 52cm and weighs 40kg.

Even with a 30 meter hose, the 750i pushes out a huge 3950PSI which is around 272BAR, one of the highest on the market. It produces this power from a very fuel-efficient 8HP, 210CC, four stroke petrol engine.

SwitZer is a lesser-known brand of high-pressure cleaners but this heavy-duty unit is popular with the domestic market due to its lower initial outlay.

It ticks all the boxes for what you would want from a petrol pressure washer, it’s lightweight at only 26kg, includes a 10-metre hose and 4 quick connect nozzles with one of them being for low-pressure detergent injection.

The 8inch wheels make it easy to move around uneven ground whilst you work on what you need to work on.

Briggs and Stratton are one of the market leaders in petrol pressure washers, engines, generators, and snow Blowers. The Briggs and Stratton 020739 Elite 3200Q is the next pressure washer on our list and comes with a big list of specs.

The 190cc engine comes equipped with a 1.1 litre fuel tank so filling up shouldn’t be that regular. Once the unit is filled with oil there’s never a need for an oil change you just need to top it up as you use it.

This engine includes one of the best quiet sense technologies that’s available which automatically tones down the engine when the washer is in use to save your ears from such a bashing.

This unit also offers an amazing feature in that it includes ReadyStart. ReadyStart stops the need to manually prime or choke the engine and will start first time, every time using their easy rope starting system.

The washer outputs 3200 psi or 220 bar of water pressure making one of the more powerful units available with a water flow of 612 litres per hour or 10.2 LPM. The Briggs and Stratton washer also includes 4 quick connect stray tips from 0 degrees, 15 degrees, 40 degrees and soap.

All the best petrol pressure washers are a similar size and this one is no different, at 65 x 58 x 55cm and weighing 29.1kg its comes into the middle of our size and weight list and comes with a 2 year manufactures warranty.

The Waspper W3000HC is built to last and proclaimed to last 5 years longer than electric models would last. The 163cc OHV (overhead valve) engine pushes out 3000 psi or 205 bar with a water flow of 8.7 LPM or 522 litres per hour. It has a 3.6 litre fuel capacity so there will be little filling up needed.

The oil pan is 0.6 litres and Waspper is one of the only machines that comes with your first bottle of oil in the box for free! The unit also includes an automatic cut off switch when the oil level drops below a certain point.

The unit itself is coupled with never-flat wheels so you can take it all-terrain and not have to worry about getting a flat, three valves which is a little lower than that of competitions, a 40cm extension lance for the spray gun part to reduce back pain from bending over whilst working and a 7.5 meter hose, again a little shorter side.

The hose that comes with the unit has been renowned for being a little on the cheap side and after a few uses and some storage, the hose has been known to split and wear away.

The size of the unit is 59 x 59 x 42cm, weighs 29.66kg, and comes with a 2 year manufacturers warranty.

The ParkerBrand is our cheapest best petrol pressure washer on the list and is great as a starter unit.

It offers quite a basic set up which is perfect for anyone looking to start off with a petrol pressure washer.

Its comes with a generous 8 meter hose and wheeled chassis for easy moving around.

The 6.5 horsepower, 4 stroke petrol engine creates a maximum PSI output of 3100psi which equates to around 213 bar meaning its overly qualified for any cleaning jobs.

The spray gun section of the product is easy to hold and slots into a holder attached to the foam handle for easy access. The nozzle is able to shoot out in three different styles, pencil spray, narrow spray, and wide spray.

The flow rate of this washer is around 11 LPM or, 660 LPH making it more economical than a hosepipe whilst providing way more cleaning power.

The ParkerBrand also includes a soap dispenser for easy cleaning of floors, cars, caravans, boats, or bikes. This can also be teamed with their snow foam pressure washer lance (separate purchase) for extra cleaning power.

A huge safety feature of this product is that it won’t actually start if the oil in the petrol engine is too low. This avoids any unnecessary costly engine repairs as there’s no chance of damage. If you do damage or break your pressure washer, you can send it to ParkerBrand for repair.

If the damage is caused by negligent parts or such, the product comes with a 2-year warranty as standard.

The engine on the RocwooD is a 7HP 4 stroke OHV (Overhead valve Engine) housing a huge 10 litre fuel capacity making this engine super-efficient.

The OHV actually makes this engine slightly quieter and lower vibrations than that of market alternatives.

You can supply the water for this unit from a garden hose, or from a standing watewr supply such as a pond or lake. 

You get a 10 meter hose making it great for cleaning harder to reach places where the unit itself might not fit.

The next pressure washer in our list is a Draper 83818 HP Expert. This little beauty comes with a petrol powered 6.5 horsepower, four stroke engine. This produces around 186 bar or 2700 psi of water pressure making it a brilliant tool in cleaning almost anything.

The water flow for this model is 7.9 litres per minute or 474 per hour. This puts it in the low category for water flow should still not make any job not too long of a task. 

The unit is 60 x 58.4 x 54.6 cm and weighs 30kg whilst dry so it’s not one of the heaviest but still rather chunky on the scale.

The Draper comes with an 8-meter, heavy duty, reinforced, abrasion resistant hose, a metal trigger on the handle for durability and a detergent tank for easy cleaning jobs. It comes with five different nozzles included with the product and even a fuel funnel with a hose for easy filling of the fuel tank.

Petrol Pressure washers have become more and more affordable which has started to really set the big boys apart from the crowd and one that does get set apart is the Kiam KM3400P.

The powerful 9HP 4 stroke engine powers a brass 3 piston triplex pump allowing up to 3400 PSI and a HUGE 15 litres per minute of water flow. This can be controlled by the throttle of course allowing for a wide variety of jobs from roof cleaning to patio restoration.

It includes 5 different power nozzles which make short work with whatever the task is at hand and with the 10M hose you can easily navigate hard to reach areas.

You can also draw from standing water which makes for a great mobile pressure washer as well as a detergent pipe for use with soap. Another handy thing to note is that this unit actually includes a small tool kit for help in emergency situations, not something you see much off in the pressure washer industry.

The last on our list is another Wilks petrol pressure washer review, the Wilks Genuine USA TX625, the little brother of the TX750.

Much more compact but still packing the same power, the 7 horsepower, 210cc 4 stroke, OHV engine pushes out the same 3950psi or 272 bar that the TX750 does.

Its slightly smaller, measuring 51 x 45 x 51cm but weighing a little more at 32kg. This might be due to the 20-meter hose that’s included, double what its big brother unit offers. This hose is split between an 8 meter and a 12 meter which can be used separately or put together.

This Wilks petrol pressure washer includes 5 snap on ceramic nozzles included with the set as well as a straight and curved lance which are great for cleaning the gutters. You also get a self-propelling drain unblocker with this unit.

You can feed this unit from a hose or a bucket/pond without any issues and pumps out 720 litres per hour or 12 litres per minute.

The Wilks TX625 comes with a 12 month manufactures warranty.
