What Is The Best Pressure Washer?

Kärcher K4 Full Control Home Pressure Washer Review
The Kärcher K4 Full Control Home Pressure Washer is the best home pressure washers on the UK market today. It’ll clean anything from your patio to your car, and you get a lot of kit for your money too.
The Karcher K4 is capable of cleaning 30 meters per hour, enough to tackle jobs in most households with time to spare.
The K4 jet washer offers 1800 watts of power and a water-cooled engine. A water-cooled engine uses water to maintain the ideal temperature, so you don’t need to worry about the unit overheating in the middle of a task.
It can spray 420 litres of water per hour with 130 bars of pressure and is capable of cleaning 30 metres per hour – that’s enough to tackle jobs in most households.
The easy to understand display on the K4’s trigger gun helps select the right pressure for the right job. The screen displays symbols for different tasks, so there’s one setting for washing the car and another for cleaning stone or brickwork on a patio for example.
Check the pressure level on the display at any time to make sure it’s right for what you’re doing at the moment and change it instantly if needed. The LED display requires two AAA batteries loaded into the trigger gun handle.
So what about attachments you ask? Well, the K4’s dirt blaster lance offers a powerful rotating point to wash off dirt or mud from tyres or wheel rims, and there’s a water butt attachment to make conservation easier. You also get a user-friendly patio cleaning attachment, patio cleaner, vario lance, and spray lance too.
Like most other Karcher pressure washers the K4 isn’t cheap, but it’s well-built and adaptable for many uses. I think the storage compartment is little fragile but other than that I haven’t found any drawbacks to the K4.
The Karcher K4 Full Control Home Pressure Washer has my vote because it’s easy to handle and changing from one function to another takes only a few seconds. Its 130 bars of pressure and telescopic handle make it perfect for versatile outdoor cleaning tasks.
- Pressure: 130bar
- Power watts: 1800
- Litres Per Hour: 420
- Hose Length: 6 metres
- Warranty: 2 years
WORX WG629E.1 MAX Cordless HYDROSHOT Portable Pressure Cleaner Review
Worx 20V Battery High Pressure Washer Hydroshot WG629E is the best pressure washer for your car, as it will draw water from any source. If you’re lucky enough to have a tap at the front of your house, it’s perfect.
This cordless pressure washer is undeniably useful. For one, you don’t even need a tap because it’ll turn a bucket of water or even a bottle into a high-powered jet of water. If you’re by a lake, pond, or river that’ll work too.
This is a great piece of kit even if you don’t have an outside tap or a power supply. You can chuck it in the car and wash your mountain bike off before it gets encrusted on the way home, blast your kid’s muddy wellies when you’re camping, wash off winter grime from a balcony, or clean an entire car from any water source.
The bar pressure maxs out at 22 bar which doesn’t seem a great deal in comparison to others in this review but that is still 10 x the power of a garden hose.
It’s powered by a rechargeable battery that’ll last around an hour with continuous use and it takes 5 hours from dead to re-charge, but if you already own other 20V Worx products their batteries are interchangeable – or you can buy them individually to add to the cleaning time.
5 hours is a longer charge up time than some lithium batteries, but this avoids battery burn out from heat build-up. To get a longer running time switch on ‘variable use’ – it’s not as powerful, but still shifts dirt.
There are multiple pressure settings on the 5-in-1 pressure nozzle that controls the jet stream and it has a rotating head to get into all the nooks and crannies. From a fine mist to a pulsating sprayer– just turn the head to pick out the setting you need. The fine mist is gentle enough to remove dust or bird mess from plants.
The hose is six metres long which is enough room to get around your car without moving a bucket for example, or you can fix the nozzle straight onto the machine for close up jobs. The lance attachment adds an extra 35 inches to the overall length.
This is a fully portable and versatile machine that you can take anywhere without a power source or water supply. Even if you already own a pressure washer this is a useful, cordless tool to add to your collection.
- Pressure: 22 bar
- Power watts: 20V
- Litres Per Hour: 150
- Hose Length: 10m
- Warranty: 3 year
Bosch EasyAquatak 120 Pressure Washer Review
The Bosch EasyAquatak 120 is powerful yet compact and it draws water from any source. It’s a proper all-rounder and many consider it the best budget pressure washer available.
The Easy Aquatak is one of those tools that you go without for ages and when you buy one, can’t remember how you managed before. One of its best functions is the ability to draw water from any source and still push out 120 bars.
This pressure washer will draw water from a garden hose or an unpressurised source such as a bucket (you need to buy a separate suction hose for that feature). That opens up a whole new cleaning world – one without an outside tap!
So let’s talk all-important power. This Bosch is small but mighty. It knocks out enough pressure to blast down your walls and patio no problem and the water stops when you release the trigger. This keeps water consumption down and prevents the biblical-style flood that can happen with other makes.
The design of this pressure washer is a bit different. It’s made with a low centre of gravity so it looks pretty quirky, but that design feature stops it toppling over. The wide base means you can tug it and it won’t fall down like the majority of pressure washers do. You can even set it on a table and it won’t fall off easily.
So what are the accessories? A fixed fan jet nozzle for basics, a rotary nozzle for stubborn dirt in nooks and crannies, and a high-pressure detergent nozzle to blast away built-up grime that needs a proper wash – the built-in detergent function saves time by simply applying when you pull the trigger.
All the accessories fit on to the machine. No-one likes hoses and nozzles lying across the garage floor so this is a real perk and invaluable if like me you constantly lose tool parts. Having them all to hand is a real time saver especially as they just click in and out of place
This pressure washer is portable with a built-in handle, versatile, and comes ready to go out of the box. It’s perfect for town life – blasting the decking clean, washing the wheelie bin out, cleaning the car, windows, and balconies.
- Pressure: 120
- Power watts: 1500
- Litres Per Hour: 350
- Hose Length: 5m
- Warranty: Up to 3 years
Karcher K2 Compact Pressure Washer Review
The Karcher K2 Compact Pressure Washer is a great all-rounder and one of the best priced pressure washers on the market, considering it’s great features.
It has an air-cooled 1400 watt motor, 110 bars of pressure and 360 litres of water flow per hour so it’s not as powerful as Karcher’s K4 – but if you don’t need all that power and water why spend more?
This jet washer is ideal for cleaning cars, bicycles and tidying up patios in small gardens. It’s lightweight and versatile enough for simple ‘not engrained with filth’ tasks such as washing the winter off a furniture set, hosing down a muddy patio, or cleaning your bike.
In terms of attachments, it has a dirtblaster lance with a rotating point jet spray that gives you up to 50% greater cleaning power than a hose, a one-way lance offering constant high pressure, a T50 T-racer patio cleaner, a detergent pouch for patio and deck cleaner, and a trigger gun. That’s a lot of attachments for a well-priced pressure washer.
You can store all these attachments in a compartment inside the unit to keep nozzles readily available and tidy.
The K2 has a detergent pipe and detergent suction tube for washing off tougher dirt – that’s unusual at this price point, and a built-in filter to prevent dirt particles from damaging the engine and pump.
It doesn’t have wheels but includes clips to carry it around.
- Pressure: 110 bar
- Power watts: 1400
- Litres Per Hour: 360
- Hose Length: 4 metres
- Warranty: 2 years
Nilfisk C130 1-6 X-Tra Pressure Washer Review
This Nilfisk C130 1-6 X-Tra Pressure Washer is the Kärcher K4’s main competitor. It’s got to be said, Nilfisk have done a great job with this model. It’s small but powerful and well worth your consideration.
The C130 has a powerful 1700W air-cooled motor, 440 litres of water per hour and the bar pressure tops at 135 bars – but it’s still gentle enough to leave the paint on your car.
This pressure washer’s powerful water flow makes it ideal for small to medium-sized patios and driveways. It has a 6-metre high-pressure hose and 6-metre electric cable, and an auto stop-start handle for safety, If you have a large space this pressure washer will help you clean it quickly.
The excellent piece of kit comes with a click and clean nozzle for more accuracy when spraying water, a spray lance with 360⁰ degree rotation, and a built-in low-pressure nozzle. There’s also a wash brush and a click and clean foam sprayer bottle for detergent.
The Nilfisk C130 is made from recycled plastic and it’s lightweight and wheel-mounted so you don’t need to be an athlete to use it
I rate the Nilfisk C130 highly because it handles a bit more water than others so it’s ideal for your car, motorbike, patio or decking – a great all-rounder.
- Pressure: 135 bar
- Power watts: 1700
- Litres Per Hour: 440
- Hose Length: 6 metres
- Warranty: 2 years
Wilks-USA RX525 High Powered Pressure Washer Review
The Wilks-USA RX525 High Powered Pressure Washer delivers 165 bar of pressure, has a click and go connect system, and comes with a full range of accessories. This makes one of the top models for power whilst still easy to use and versatile.
This product is well-built from the highest quality materials including a copper-wound brushless 1800 watt motor that delivers 450 litres per hour flow rate and unbeatable reliability.
The unit is lightweight and easy to manoeuvre with sturdy wheels and a comfortable telescopic handle.
It comes with a full range of accessories including a lance, a gutter lance, 3 x varying nozzles, a turbo wand, a fixed washer brush, a rotary brush and patio cleaner. The pressure washer also comes with an 8-metre hose and 5-metre power cable to get into difficult areas and complete tricky jobs like gutter cleaning and car washing with less hassle.
I like the patio cleaning tool that makes removing winter’s grime and algae a breeze. The unit also has a detergent spray system to make cleaning even more quick and easy.
Overall this is good option if you are looking for a machine that does the job effectively and has a really excellent build quality.
- Pressure: 165 bar
- Power watts: 1800
- Litres Per Hour: 450
- Hose Length: 8 metres
- Warranty: 2 years
Nilfisk C110 4-5 X-Tra Pressure Washer Review
The Nilfisk C110 4-5 X-Tra Pressure Washer offers great value for money. In my opinion it’s one of the best domestic pressure washers for those on a low budget.
The air-cooled 1400 Watt motor, 110 bars of pressure, and high water flow rate of 440 litres per hour makes the Nilfisk C110 great on small areas, but I’d recommend a higher bar pressure model for thorough cleaning of large driveways or very dirty patios.
The Nilfisk has a 5-metre high-pressure hose and five-metre electric cable to let you move from patio to washing cars easily.
The C110 has a pre-fitted filter to keep dirt out of the water supply. That’s a good feature if you get caught up in your work and have no time to manually check.
It also features an automatic on/off function powered by a thermal sensor. The sensor shuts off the pump when the load is too high, which saves energy and water.
Reviewers say the C110 can easily clean moss from garages and bird droppings from patios with the standard accessories that come with the unit.
One of the best accessories is the click and clean tornado nozzle that gives you fan jet power for cleaning and rinsing average surfaces such as patio furniture and plant pots.
There’s also the powerspeed nozzle that works well on tougher stains and dirt – the kind you might find on muddy patios or smudged shed walls.
The Nilfisk C110 offers a small but powerful unit comparable to many Karcher models. If Karcher pressure washers are too bulky or expensive for you, this is a good alternative. It’s a tough entry-level unit that doesn’t use a lot of power compared to the other best power washers on this list – but it works just as well.
Mobile and easy to transport from place to place, the Nilfisk C110 4-5 X-Tra pressure washer scores points for its practical attachments and strong, yet lightweight build -but some say it’s hard to disconnect attachments.
- Pressure: 110 bar
- Power watts: 1400
- Litres Per Hour: 440
- Hose Length: 5 metres
- Warranty: 2 years
Makita HW101 Compact Pressure Washer Review
The Makita HW101 Compact Pressure Washer is a compact machine that delivers more power than you would expect from a small pressure washer. It’s ideal for cleaning cars and patio furniture.
The powerful 1300 watt motor produces 360 litres of water per hour with bar pressure of 100 max.
This compact machine has a 3-metre hose as well as a lance and gun attachment. The unit itself is well built, light and compact – ideal if you don’t have much space to store a large pressure washer.
This pressure washer doesn’t come with all the attachments of larger more expensive machines and it doesn’t have a detergent spray system, so you have to apply detergent with the spray bottle provided.
That said this does a fantastic job of cleaning patios, decks and other general cleaning tasks without the hefty price tag.
This is an ideal entry-level machine for general cleaning tasks and it won’t break the bank. Overall, it’s one of the best small pressures washers you can buy.
- Pressure: 100 bar
- Power watts: 1300
- Litres Per Hour: 360
- Hose Length: 3 metres
- Warranty: 3 years
VonHaus 1600W Pressure Washer Review
The VonHaus 1600W Pressure Washer is a compact, budget-friendly pressure washer that produces 330 litres of water per hour at 90 bar of pressure.
It has 1600 watts which is a good amount and helps get deep cleaning done quickly despite the lower bar pressure.
The pressure washer comes with a quick-connect spray gun as well as a detergent bottle to spray on your cleaning product before washing. The nozzle is adjustable and the 5-metre hose allows you to clean large items like cars with ease.
This is a compact and lightweight machine that nonetheless delivers on power with its 1600 watt motor. It does a great job on lightly soiled patios, garden furniture and cars. The unit is lightweight and compact making it easy to move around and store.
This is a good budget option for cleaning lightly dirtied patios, cars and garden furniture.
- Pressure: 90 bar
- Power watts: 1600
- Litres Per Hour: 330
- Hose Length: 5 metres
- Warranty: 2 years
Pressure Washer Buyers Guide
How Does A Pressure Washer Work?
A pressure washer sucks water from a tap or bucket and shoots it out at high speed to blast away dirt, dust, and grime.
Getting technical, but only a little, a motor powers a water pump and the pump forces a narrow jet of water out when you pull the nozzle trigger. The more ‘bar pressure’ and water flow there is the faster and harder the water will shoot out. Some models have a little compartment for detergent if you want to add to the cleansing mix.
That really is it so they are nothing to be afraid of!
Water is such a good way to clean things because it’s non-abrasive and gentle on surfaces like car paint or the grouting between patio slabs.
That said, take it easy! Some of the best pressure washers on the UK market are really powerful and they can break down surfaces in no time at all.
How To Use A Pressure Washer
The good news is that a pressure washer uses less water than a standard hose and they make cleaning baked on grime much easier than scrubbing.
First up, read the instructions. This bit is important because brand models vary but here’s the standard way to use a pressure washer.
Attach the machine’s high-pressure hose to the lance.
Let your garden hose run for a bit to clear any debris in the pipe. You won’t want high-velocity gravel flying into your car paint.
Connect the hose to your garden tap or place the suction hose into a body of water such as a water butt.
Check all the fittings are nice and tight – important!
Plug it in, or in the case of a petrol pressure washer, start the engine.
Turn the pressure washer to its lowest setting and let it warm up a little
Squeeze the trigger handle gently. If water sprays out it’s time to clean. If it doesn’t, check your connections.
Hold the nozzle at 45 degrees to a surface and begin cleaning. Start at the top of vertical surfaces and keep moving the lance.
Add detergent now if you’re using it.
Rinse with plain water and spray surfaces at the pressure washer’s widest setting for a final rinse down.
How To Connect A Garden Hose To A Pressure Washer
This sounds simple but it can be tricky and what makes things more complicated is that different models use varying methods.
Here’s the standard method but do check the manufacturer’s instructions.
Fully unwind the hose so that kinks don’t prevent water flow and let it run for a minute to clear out any debris. Turn it off and let water drain free.
Now you need to attach the garden hose to the water inlet port on the pressure washer. It’s often colour-coded or labelled ‘screw attachment’ or the ‘free flow connector’. It basically a hole through which water can flow into the machine before blasting out the other side.
Screw it in tightly making sure the connectors are straight. If it won’t screw on, check to see if there’s a pull back valve. These clip the hose into place rather than screwing it in.
If it’s not working, the manual is a good place to search for help. Some pressure washer companies like Wilks have a customer service line to call so don’t be shy.
What Can You Use A Pressure Washer For?
Here are a few other more unusual uses:
- Prepare outside surfaces for painting
- Clean kids play equipment
- Clean outdoor furniture
- Clean up garage or shed floors
- De-slip the front door entrance steps
- Clean mouldy fencing
- Collect leaf fall
- Spot cleaning mould
- Clean out wheelie bin
- Wash encrusted garden tools
- (With the right accessories) clear guttering and unblock drains
- Clean the BBQ
And more randomly – blast a stuck football from a tree or peel your new potatoes!
How To Use Pressure Washer Detergent?
You won’t need much pressure washer detergent because the sheer force of plain water is usually enough to dislodge most grime, but sometimes you’d like to give the car a good foamy wash down or polish up the patio slabs – it’s a good idea to use detergent on mouldy patios as plain water can spread mould spores.
Again, detergent directions will differ with manufacturers so always read the instructions if there’s a built-in detergent compartment or a corresponding accessory.
If not, use a spray bottle or sponge to get the detergent on and then pressure wash it clean.
First up you should always remove the majority of dirt before applying detergent so it can really get into the stains.
Its best to buy purpose-made pressure washer detergent as soap, laundry liquid, or washing up liquid can foam up into huge amounts that just won’t wash away.
Handy Pressure Washer Accessories
You may have a particular task in mind such as cleaning a gutter which needs a handy tool. Here are a few pressure washer accessories currently on the market:
Drain and gutter cleaning kits – helps you clean without ladders or opening up a drainpipe.
Patio cleaner – These are fast, splash-free attachments that often have several rotating heads.
Telescopic lance – Get high-pressure water to high places such as shutters, fascia boards and eaves.
Extension Hose – An extension hose gives you more reach.
Under chassis nozzle – this helps you clean the wheel arches beneath your car
Soft Pressure Washer Brush – a large brush with an outer ring to prevent scratches on glass or caravans
One Way Lance – for spot cleaning high-pressure areas.
Electric vs Petrol Pressure Washers
Whether you buy an electric pressure washer or a petrol pressure washer is down to its intended use.
Electric pressure washers are usually better for home use where there is an electrical socket whereas petrol pressure washers are noisy but can go anywhere.
Should I Buy An Electric Pressure Washer?
They are quieter and easy to start with the flick of a button. Electric pressure washers are now powerful enough to clean encrusted patios and driveways and can tackle any outside townhouse job.
They are more lightweight than their petrol cousins and simply plug into a power source and outside tap. A good selection will also run from a water bottle or bucket.
The disadvantage is that they have to be plugged in and that’s a problem if the object or area you want to clean isn’t near a socket.
Should I Buy A Petrol Pressure Washer?
These are best for regular large-scale jobs and heavy-duty use. Farmers, landscape gardeners and other professionals tend to use petrol as they are incredibly powerful and rather obviously, don’t need a power socket to run.
That said if you have a big outdoor space a petrol pressure washer gives you portability and power. On the downside they are noisy, smelly and often heavy.
There is one more choice for lighter jobs – a battery-powered pressure washer like WORX in the review above. This runs from an interchangeable lithium battery which is perfect if you have lighter jobs without a power supply nearby.
Pressure Washer Safety Advice
As with all tools you must keep yourself safe. Always keep in mind that electricity and water are not a good mix.
Poorly maintained cables
If you need to move your pressure washer pick it up, don’t drag it by the hose or cable. This leads to wear and tear on the power supply and potentially electric shocks. If you notice damage to your pressure washer don’t use it. Whip out that warranty.
Power cables and hoses are prime criminals in ‘tripping people up’. When cables are trailing around watch where you step and keep pets or children well away.
Water is slippery as is detergent. Always use the right amount of detergent to avoid unnecessary soap suds.
You will get wet using a pressure washer so dress accordingly with sturdy shoes. Eye protection is a good idea too as water and filth will splash back from walls, fences and the patio.
Pressure washers fire out water so fast it can seriously hurt a person. Their eyes, ears, mouth for example and even tougher body parts can get horribly bruised – it is not the same thing as a garden hose. Keep the lance pointing downward.
Never ever fire water at electrical cables, into open windows, or intruding cats. We are watching you.
Handy Pressure Washer Glossary
There’s lots of terminology around pressure washers that makes it hard to understand what you’re looking at.
Here’s a quick guide to the main acronyms and terms.
Bar Pressure: This is a measurement of pressure. The higher the bar the more force water sprays out. The numbers – for example ‘220’ – mean its 220 times more powerful than the air pressure around you. It’s also called PSI which is ‘pounds per square inch’.
Water Flow l/h: Water flow in litres per hour. This indicates how much water the pressure washer can deal with. It’s usually measured in litres and hours but sometimes per minute and on occasion gallons per minute.
The more water flows the quicker and more forceful the pressure washer is. A higher litre per hour means less time cleaning.
Detergent Intake: This is the container or pipe that soap travels down before spraying out.
Hose Length: An obvious one – this is the length of the high-pressure hose.
High Pressure Hose: The hose that runs from your machine and holds the nozzle and attachments.
A standard hose would explode from the pressure so don’t use one there. If you need to replace a high-pressure hose get one that can withstand more pressure than the machine pumps out.
Water inlet: A hose that connects the pressure washer to the main water supply
High Pressure Outlet: This is the connection for a high-pressure hose.
High-Pressure Pump: The pump is the part that pushes water from the washer. It’s driven by the electric or petrol motor, so the more powerful the motor the higher the pressure.
Which Is The Best Pressure Washer For Me?
So what is the best jet washer for the UK market?
It depends what you’ll be using it for!
If you’re struggling to narrow the options have a think about what you want a pressure washer for and choose by bar pressure.
It’s no good choosing 22 bar if you need to clean algae and a mould spotted patio, but going overboard with a petrol fired 440 bar washer to clean the car on Sundays will only lead to tears and a big garage bill.
So many pressure washers, so little time!
Take a look at my suggestions below to save yourself some stress.
100 BAR and below
- Wheelie bins
- Garden furniture
- Guttering and facias
- Car cleaning plus caravans and boats
A lot of people use a pressure washer for car cleaning AND patios – so what’s the best pressure washer then?
Well, if you need it for a mixture of jobs it’s about how much time you have to spare.
You could go bigger and use the lower settings as this will save time. Just be careful and always pay attention.
Go mid-range and spend longer on the heavy dirt jobs. A 120 bar pressure washer will clean your decking – it’ll just take longer than a 130+.
So that’s pressure washers for you. They are handy tools for sure and if you buy a good make with excellent reviews it’ll last years.
