Wilks Genuine USA TX750i Petrol Pressure Washer review

Specifications

  • Engine: 210cc
  • Max Pressure: 272 bar
  • Flow Rate: 11 L/min
  • Hose Length: 30 m total
  • Weight: 40 kg
  • No. of Nozzles: 6

Whilst some pressure washers can hold you back, keeping you tethered to the wall by not offering a decent amount of hose, Wilks’ USA TX750i Petrol pressure washer comes with a 30 m hose that makes it possible to use it almost anywhere in the back or front garden.

Also, if you’re naturally concerned about how to deal with such a long hose when it’s not in use, there is a lot of well-thought-out onboard storage for both the standard 20 m hose, and the 10 m extension. If you’re working down the end of the garden, there’s enough length for that, but if you’re closer to home then you don’t need to worry about tripping over unruly coils of hose.

A hose with a filter system is included as well, which can be used to draw water from a bucket. So, in the unlikely event of working somewhere that simply doesn’t have access to a tap within 30 m, you can still make use of this powerful pressure washer.

Speaking of power, the TX705i can produce 272 bars of pressure which makes it one of the most powerful pressure washers featured here. Considering this combination of power, construction, and price, whilst it may not be the cheapest model available, it still offers good value for everything that’s included.

There can be a few teething problems when it comes to getting used to this machine’s specific personality: it vibrates quite a lot when used on low revs, and requires a spanner to change over the lances and hose. Like other models, it comes with various nozzles for creating different sprays (five, to be precise), but, whilst these are stored on the unit, they can jump out as a result of the vibrations.

There are, however, also a lot of practical features which make this pressure washer easy to use, such as the long cable length and ability to draw from any water source, so it’s really a case of weighing up the pros and cons depending on what jobs you’re hoping to get done.

Pros

  • Very easy to use and transport
  • 30 m of hose in total - ample reach for any task
  • 6 ‘click and go’ nozzles for blasting, stripping, cleaning, washing and detergent application
  • Built in 6L detergent tank for stubborn jobs

Cons

  • Poor and unclear assembly instructions
  • Changing the hose or lance is tricky and requires the use of a spanner
  • Uses a lot of fuel - not economical to run
  • The nozzles fall out of the rack frequently, so it's not practical to store them there

Wilks Genuine USA TX625 Petrol Pressure Washer review

Specifications

  • Engine: 210cc
  • Max Pressure: 272 bar
  • Flow Rate: 12 L/min
  • Hose Length: 20 m total
  • Weight: 32 kg
  • No. of Nozzles: 6

The Wilks Genuine USA TX625 Petrol Pressure Washer achieves the sort of results that we all expect to see when using a power washer – we’re talking write-in-the-grime levels of cleaning power.

It’s cheaper than some petrol models, but still has a maximum pressure output of 272 bars which is powerful enough to tackle cars, driveways and those all-important grimy patio slabs.

The pressure doesn’t stay up at 272 bars continuously, after an initial spurt, but it doesn’t drop down too dramatically either.

Running with a 4-stroke 210 cc engine, it uses unleaded petrol and has a separate oil tank which needs to be kept topped up. The recoil pull start is relatively easy to use, generally starting the engine after a couple of pulls.

Where this pressure washer really comes into its own is in the number of functional accessories provided. A straight and curved lance come included, meaning you can unclog gutters without having to use a ladder and clean under car wheel arches too.

There are also five different pressure nozzles to change between, which all work effectively for different purposes – blasting, stripping, cleaning, washing, and detergent application.

As you can see, Wilks have clearly decided not to leave anything to chance, providing a nozzle for almost any purpose.

A particularly interesting attachment, which doesn’t often come included with pressure washers, is the ‘self-propelled drain cleaner’. It connects to the pressure washer’s nozzle with a hose, and has a rounded metal spray head. If you put it into a blocked drain, it will propel itself through the blockage, using the power of the washer to clear the channel.

This washer also offers flexibility in terms of where you can pull the water from – if you’re near a tap, you can simply hook the 12 m hose up to the faucet, but you can also draw water from static water sources like buckets, water butts and ponds.

What this really means is, this is one of the best petrol pressure washers to use just about anywhere, as you aren’t limited by tap proximity.

An additional 8 m hose is also included, which can be connected to the standard 12 m hose, to create a maximum reach of 20 m – more than enough to complete most jobs around the home.

Pros

  • Comes with 12 m hose plus extra 8 m hose so you can use it around your property without having to constantly move it
  • Impressive 3950 PSI at 272 bar output
  • Comes with a huge range of useful attachments
  • The pressure is more than enough for most outdoor cleaning jobs

Cons

  • Build quality isn't as solid as others on the market
  • Getting the petrol cap off to refuel is a little tricky
  • Uses soap very quickly so a 50/50 mix is recommended for easier jobs
  • The instruction manual needs to be downloaded from the internet

Briggs & Stratton ELITE 3200Q Petrol Pressure Washer review

Specifications

  • Engine: 190cc
  • Max Pressure: 220 bar
  • Flow Rate: 10.2 L/min
  • Hose Length: 9 m
  • Weight: 24 kg
  • No. of Nozzles: 4

Petrol machines aren’t exactly renowned for their quiet running, but the Briggs and Stratton Elite pressure washer does a good job of keeping noise down where possible (whilst still providing a powerful clean).

When the engine is running idle, waiting for the next task, the engine drops down to be 40% quieter. This avoids excessive noise being made unnecessarily when the pressure washer isn’t in use, and can make the machine more comfortable to use for extended periods compared to standard petrol motors.

Speaking of comfort, the 190 cc Briggs and Stratton engine comes with an easy-start system which needs no priming or choke. It’s pretty reliable to get going on the first or second pull of the recoil, which can save a lot of time and energy – we’ve all been there, wearing ourselves out trying to persuade a petrol machine to spring to life.

Plus, reliability isn’t the only benefit of this motor. The power also means that the washer is able to deliver a maximum of 220 bars of pressure which sees dirt physically running away from the jet stream.

The four spray nozzles are quick to connect and provide a good amount of variety, ranging from a pin-point jet to a wide fan. The only main thing missing, accessory wise, is a curved lance. Whilst these come included with some other models, only a straight lance is provided with this Briggs & Stratton washer which can make it harder to clean drains and other hard-to-reach areas.

The hose is only 9 m long as well, which, again, can reduce this washer’s ability to be used for more awkward cleaning jobs. The majority of petrol pressure washers come with longer hoses, or even two which can be joined together, so this model can feel a little restrictive.

Pros

  • Very simple to build and get set up
  • Any unused connectors can be stored on the body of the pressure washers, so you are unlikely to misplace them
  • 40% reduction in noise when the spray gun trigger is released

Cons

  • Harder to change the connectors than expected
  • The 9m hose is shorter than others on the market

Waspper Petrol Pressure Washer review

Specifications

  • Engine: 196cc
  • Max Pressure: 207 bar
  • Flow Rate: 8.5 L/min
  • Hose Length: 7.5 m
  • Weight: 27.8 kg
  • No. of Nozzles: 3

Given that petrol pressure washers don’t come cheap, you don’t want one that is going to fall apart after a couple of uses. Whilst it’s true that most of these machines are built pretty sturdily, WASPPER’s W3000HA petrol pressure washer has a few extra features that ‘level it up’ in terms of durability.

Given that several components on the body are made from rust-resistant metal, as well as the fact it has a stainless-steel spray gun and aluminium lance, this machine feels sturdy and can deal with a couple of knocks and bumps without immediately showing wear and tear. The interchangeable spray nozzles also have metal bases, which don’t feel like they will degrade over time, and are easy to click in and out of the lance.

There are three spray nozzles in total, a narrow 15° head, a wider 40° option, and one which is specifically designed to be compatible when applying soap. These make it possible to do a really refined jet wash, blasting years of dirt from the driveway, or to cover a slightly wider area – cleaning the decking or patio furniture.

According to the specs, the 196 c Peggas engine is capable of pushing out 8.5 L of water per minute – whilst it’s impossible to measure this to know for sure, it’s certainly noticeable that this powerful 207-bar water pressure washer creates results that aren’t disappointing. In fact, it’s one of those tools that has you looking for something else to clean, even when all the jobs are technically done (warning: you might even find yourself offering to wash your neighbour’s car).

One thing that may slightly displease the neighbours (even more reason to offer that free car wash…) is the sheer volume that comes from this petrol machine. It’s certainly not the best petrol pressure washer to use early in the morning or late at night, and it’s pretty loud even on idle, but then again – rarely are petrol engines particularly quiet.

Pros

  • Powerful enough for tough jobs at 3000 PSI
  • Well built with a reliable construction
  • The rubber bumpers between the engine and the frame reduce vibrations for a more comfortable experience
  • No tools are required for assembly and it goes together easily

Cons

  • No funnel is included so you'll have to source one to make it easier to put in the oil
  • 7.5 m hose may not be long enough for some jobs
  • Relatively noisy so may disrupt neighbours

Waspper W2900HA Petrol Pressure Washer review

Specifications

  • Engine: 196cc
  • Max Pressure: 200 bar
  • Flow Rate: 8.5 L/min
  • Hose Length: 7.5 m
  • Weight: 27.5 kg
  • No. of Nozzles: 4

When a name like Honda starts getting involved with pressure washers, you know you’re in for something good. After all, you only need to head along the M1 for a couple of miles to see examples of their reliable petrol engines at work.

The WASPPER W2900HA Petrol Pressure Washer is powered by a 196 cc Honda engine which is reassuring in terms of quality, and impressive in terms of power. It’s the sort of machine that lifts stains out of concrete paving, instead of just removing the top layer of dirt.

As with most pressure washers, it comes with a variety of spray nozzles that quickly click in and out so that it’s no hassle to change between jobs – whilst the smallest 15° nozzle creates a powerful pin-point jet, the larger 40° option makes a wider spray that is useful for blasting dirt off larger areas like decking. It’s also easy to keep the nozzles all together in one place as they store on the body of the unit, which means they’re always right where you need them next time the pressure washer comes out.

With a spray gun that is more ergonomic than most, it’s also possible to use this pressure washing with one hand, leaving the other hand free to wheel the base unit around when necessary. Whilst the included hose is 7.5 m long, it can feel a little short for some jobs (and it’s shorter than the other hoses of other models featured here); you need to either make sure you’re close to a tap, or buy a self-suction hose separately that will enable this washer to draw water from any static water source.

The maximum pressure of 200 bars cleans deep-seated grub off patios and driveways, and it can also be used to wash the car as well – the 40 cm lance creates a bit of distance which can make it easier to clean in spots like wheel arches without getting soaked.

The primary, most noticeable, downside from using this machine is the noise. It’s pretty loud when it gets going, and doesn’t really die down until the motor is shut off again. Ear protectors are definitely recommended, and so is choosing a time to pressure wash which won’t disturb the neighbours…

Pros

  • Easy to manoeuvre across hard surfaces thanks to the 12” puncture-proof wheels
  • 4 nozzles and engine oil included
  • The rubber bumpers between the engine and the frame reduce vibrations for a more comfortable experience
  • Suitable for one handed operation
  • Engine oil comes included, so, as long as you have petrol, you can use it straight away

Cons

  • Noisier than others on the market
  • Plastic wheels struggle on tougher terrains
  • 7.5 m hose may not be long enough for some jobs
  • Not quite as powerful as other models on the market

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 true allies in the fight against grime.

There are a few considerations to bear in mind when choosing the best petrol pressure washer, so take a look at the tips below to help you make an informed decision:

Petrol Pressure Washers Vs. Electric

Whilst electric pressure washers are certainly useful pieces of kit in the home environment, petrol-powered pressure washers hold a number of advantages.

The biggest 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.

Choosing the Right Engine Power

A top CC engine like the Wilks’ USA TX750i Petrol pressure washer will generally have around 5 – 10 horsepower, helping you get extensive mucky jobs done quickly. Just imagine the power of that many horses behind you as you hose down your patio.

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.

How to Decide on Water Pressure

Water pressure is important – it’s what shifts the filth.

Petrol pressure washers usually have a higher water pressure than electric machines.

For deep-cleaning or commercial jobs, look for pressure washers with minimum of 220 bars – for example, the Wilks Genuine brand or the Waspper Petrol Pressure Washer.

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.

The Importance of Flow Rate

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.

Detergent Systems and Other Accessories

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.

Manoeuvrability is Important Too

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.

Check If it Has a Warranty

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

How does a petrol pressure washer work?

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.

Clever stuff.

How do I use and refill my petrol pressure washer?

Using a petrol pressure washer is a bit more complicated than simply plugging it into the mains Here’s a quick guide:

  1. Remove the oil dipstick and fill it up to the line with the correct oil (look in the user manual)
  2. Unscrew the petrol cap and fill the tank with the correct fuel e.g. unleaded petrol
  3. Connect the hose to the water tap/water butt/bucket
  4. Attach the high-pressure hose to the spray gun
  5. Take the other end of the high-pressure hose and attach it to the pump water outlet
  6. Turn the water source on
  7. Turn the engine on
  8. Turn the fuel valve on
  9. Apply the choke if necessary
  10. Pull the starter cord
  11. 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.

Can I damage surfaces by using a pressure washer?

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
