Pressure Washer: The Correct Technical Term
A pressure washer uses cold water forced through a pump at high pressure to remove dirt, moss and grime.
Key Characteristics
✔ Cold water only
✔ High pressure (measured in PSI or bar)
✔ Most common type sold to homeowners
✔ Available in electric, petrol and battery models
Best For
✔ Patios and paths
✔ Driveways and block paving
✔ Garden furniture and walls
✔ Cars, bikes and decking (with correct nozzle)
In the UK, almost all domestic machines are technically pressure washers.
Jet Wash: A Popular Alternative Name (Not a Different Machine)
Jet wash is not a separate type of machine — it’s simply a casual or marketing term used to describe a pressure washer.
What It Really Means
✔ Same machine as a pressure washer
✔ Uses cold water
✔ Same pressure and flow principles
✔ Commonly used in adverts and everyday speech
Why the Term Exists
• Sounds more powerful
• Popular in car-cleaning language
• Easier shorthand for consumers
If someone says “jet wash,” they almost always mean a standard pressure washer.
Power Wash: Hot Water Cleaning (The Real Difference)
A power washer uses heated (hot) water as well as pressure. This is where the genuine technical difference lies.
Key Characteristics
✔ Hot or heated water
✔ Higher cost and heavier build
✔ Often petrol-powered or commercial grade
✔ Rare in typical UK homes
Best For
✔ Oil and grease stains
✔ Workshops and commercial yards
✔ Heavy industrial cleaning
✔ Thick, baked-on grime
Heat helps break down grease and oil far more effectively than cold water alone.
Side-by-Side Comparison
| Term | Water Type | Pressure | Typical Use |
|---|---|---|---|
| Pressure Washer | Cold | High | Domestic & garden cleaning |
| Jet Wash | Cold | High | Same as pressure washer |
| Power Wash | Hot | High | Commercial & heavy-duty jobs |
Which One Do You Actually Need?
Choose a Pressure Washer / Jet Wash If:
✔ You’re cleaning patios, paths or decking
✔ You wash cars, bikes or garden furniture
✔ You want an affordable, easy-to-use machine
✔ You’re a typical UK homeowner
This covers around 90% of household cleaning needs.
Choose a Power Washer If:
✔ You regularly deal with oil or grease
✔ You clean large commercial or industrial areas
✔ You need professional-level performance
✔ Budget, size and weight are not concerns
For most homes, this is overkill.
Common Myths Explained
“Jet wash is more powerful than a pressure washer”
False — they’re the same thing.
“Power wash just means higher pressure”
False — it means hot water, not extra PSI.
“You need a power wash for patios”
Not true — cold-water pressure washers handle patios perfectly.
Final Thoughts
In the UK, pressure washer is the correct technical term.
Jet wash is simply another name for the same machine.
Power wash genuinely means hot-water cleaning — and is rarely needed at home.
For most gardens, driveways and outdoor spaces, a good cold-water pressure washer delivers excellent results without the cost, weight or complexity of a hot-water system.
Understanding the difference helps you buy smarter and avoid marketing confusion.
