Pressure washers have become a go-to tool for homes and businesses across the UK. They make light work of dirt, grime and outdoor cleaning jobs that would otherwise take hours by hand.
From patios and driveways to vehicles, decking, garden furniture and gutters, a pressure washer is one of the most useful bits of equipment you can own. The challenge is choosing the right one.
This guide breaks it down in a simple way, so you can choose a machine that suits your jobs, your budget and how often you plan to use it.
Start with one question: what type of user are you?
Before looking at specs, think about how you’ll actually use the machine.
If it’s for occasional jobs around the home, your needs will be very different from someone using a pressure washer every day for commercial work.
In most cases, buyers fit into one of three groups: domestic, semi-professional, or professional.
Domestic pressure washers
If you want to keep on top of jobs around the home, a domestic pressure washer is usually the right place to start.
These machines are designed for occasional use and are ideal for cleaning:
- patios and paths
- cars and bikes
- garden furniture
- decking
- smaller outdoor areas
Most domestic pressure washers are electric, which makes them easy to store, simple to use and a good fit for general household cleaning.
Semi-professional pressure washers
Semi-professional machines sit between domestic and full commercial units.
They are a good option if you:
- clean larger areas regularly
- want more power and durability
- need something tougher than a standard DIY machine
- do light commercial or weekend work
Think of these as “heavy domestic” or “light trade” pressure washers. They are built for more frequent use and tougher jobs without the cost of a full professional setup.
Professional pressure washers
Professional pressure washers are built for demanding, day-to-day use.
These are the machines used for commercial cleaning, trade work and heavy-duty applications where performance and reliability matter. They are typically more powerful, more robust and built with higher-grade pumps and engines than domestic models.
They are best suited to:
- larger vehicles and machinery
- commercial yards and hardstanding
- construction and trade use
- demanding outdoor cleaning jobs
Quick guide: which pressure washer suits which jobs?
As a simple rule:
Domestic machines are best for smaller jobs around the home, including cars, bikes and outdoor furniture.
Semi-professional machines are a better fit for larger areas such as decking, fencing, patios and regular vehicle cleaning.
Professional machines are designed for commercial use, including heavy-duty cleaning of larger surfaces, equipment and vehicles.
How much should you spend?
As a rough guide:
- Domestic: £80–£350
- Semi-professional: £350–£600
- Professional: £600–£2,000+
Price should always be weighed against how often you’ll use the machine. Spending less on a unit that is underpowered or not built for your workload often costs more in the long run.
It is also worth thinking beyond the purchase price. Build quality, warranty, spare parts and aftersales support make a big difference over time.
Petrol or electric pressure washer: which is better?
There is no single “best” option. It depends on your use case.
Electric pressure washers
Electric models are usually the best fit for domestic users. They are typically lighter, easier to move and store, and straightforward to use for routine cleaning jobs around the house and garden.
They are a strong choice if you want something convenient for occasional use.
Petrol pressure washers
Petrol pressure washers are generally better suited to heavier-duty work, light commercial use and professional jobs.
They tend to offer:
- stronger performance
- greater portability (especially where no power supply is nearby)
- better suitability for tougher terrain and outdoor environments
If you need a machine for regular, demanding work, petrol is often the better long-term option.
Why the pump matters more than people think
The pump is one of the most important parts of any pressure washer. It is what generates the pressure and drives cleaning performance.
For occasional domestic use, a standard pump setup is usually more than adequate. For heavier or more frequent use, pump quality becomes much more important.
Domestic pump types
Many domestic pressure washers use axial cam pumps. These are commonly found on DIY and entry-level machines and are suitable for occasional use.
Professional pump types
Professional-grade machines are more likely to use higher-spec pumps designed for longer runtimes and more demanding workloads. If you are using a machine regularly for trade or commercial work, pump quality is one of the key differences worth paying for.
The short version: if you are only cleaning the patio a few times a year, a domestic machine is fine. If you are working with a pressure washer regularly, invest in the right pump and the right class of machine.
Useful features and accessories to consider
Accessories can make a big difference, especially if you are cleaning a variety of surfaces.
Not everyone needs every attachment, so focus on the accessories that match your jobs.
Telescopic lance
Useful for hard-to-reach areas such as gutters, fascias and high exterior surfaces.
Snow foam lance
A popular choice for vehicle cleaning. It helps apply foam evenly and makes it easier to loosen dirt before rinsing.
U-bend lance / gutter attachment
Helpful for awkward angles, wheel arches and gutter cleaning where a standard lance is difficult to position.
Built-in detergent tank
Makes it easier to apply cleaning solution without switching equipment.
Brush attachments
Good for more delicate surfaces such as conservatories, greenhouses and painted areas.
Hose storage
A simple feature, but useful for keeping hoses tidy and reducing damage in storage.
Flat surface cleaner (Whirlaway style)
Excellent for patios, driveways and paths. These attachments can speed up cleaning and help reduce overspray.
Rotary turbo nozzle
A powerful nozzle for tougher jobs such as concrete cleaning and stubborn grime. Always check it is suitable for your machine’s pressure rating.
Pressure washer buying terms explained (simple glossary)
Pressure washer terminology can be confusing, especially if it’s your first purchase. Here are the key terms to know.
PSI
Pressure output, shown as pounds per square inch. Higher PSI usually means stronger cleaning power.
Flow rate
How much water the machine moves, usually shown in litres per minute (L/min) or litres per hour. Flow rate matters just as much as pressure.
Pump
The component that pressurises the water and sends it through the hose.
Lance
The handheld trigger and wand assembly used to direct the water.
Nozzle
Fitted to the end of the lance. Different nozzles change the spray pattern and cleaning intensity.
Turbo nozzle
A rotating high-power nozzle designed for tougher cleaning jobs.
Detergent tank
A built-in tank on some machines that allows detergent to be applied through the system.
Recoil start
Pull-cord starting system, common on petrol machines.
Electric start
Key or button start on selected petrol or diesel machines.
Quick release (Q/R)
A connection type that allows accessories and hoses to be fitted and removed quickly.
Final thoughts
The best pressure washer is the one that matches your workload.
If you are cleaning around the home a few times a month, a domestic machine is usually all you need. If you are tackling larger jobs regularly or using it for work, step up to a semi-professional or professional unit built for heavier use.
A little planning now will save you money, frustration and upgrade regrets later.
