The £49 Hose Attachment That's Making £400 Pressure Washers Pointless
A mechanical engineer from Sheffield spent 30 years optimising water-pressure systems. Then he walked into a DIY shop, looked at a £400 price tag, and decided the industry had been getting away with it long enough.
▸ Real footage — the Jetterix hooked up to a standard garden hose, lifting years of moss and grime off concrete in seconds.
Adam Hartley (58) didn't set out to upend a £10-billion industry.
He just wanted to clean his own driveway without paying somebody half a week's wages to do it for him.
He'd been putting it off for months — not out of laziness, but because every option on the market felt like a swizz. Hire a machine. Buy a machine. Get a crew round. Each one more expensive and more faff than the last.
So Hartley did what engineers do. He stopped staring at what was on the shelf at the local B&Q — and started thinking about what was actually possible.
The Problem No One in the Industry Wanted to Solve
Hartley spent 30 years designing hydraulic systems for industrial clients across Yorkshire. He understood, better than almost anyone, how water pressure actually behaves — and how badly the consumer market has been wasting it.
"A standard garden hose pushes water at 3 to 4 bar. That's real pressure. The moment it hits a conventional spray head, eighty per cent of that force disperses into the air before it ever reaches the surface."
He pauses.
Pressure-washer manufacturers sell £400 machines because they've convinced homeowners there's no other way. Hartley knew there was.
After several months of prototypes in his garage — testing chamber geometries, nozzle angles, internal flow paths — he produced something that, at the price it would eventually sell for, had no business existing.
The Test That Stopped the Whole Street
The first proper test was his own driveway. Twenty minutes. What years of weathering, moss and accumulated grime had built up — gone.
Hartley hadn't hired anyone. He was holding a device the size of a water bottle, attached to a garden hose he'd had in the shed for six years.
Word travels the way it does when something actually works. Within a week, three houses on his road had borrowed the prototype. Within a month he had more requests than he could handle.
That prototype became the Jetterix.

What Makes the Jetterix Different from Everything Else on the Market
The Jetterix isn't a standard nozzle. Standard nozzles just narrow the opening — that produces a thinner stream, not more cleaning force. It's the thumb-over-the-hose trick. More reach, barely more power.
The Jetterix uses a precision-engineered high-velocity compression chamber that restructures the water flow inside the device, before it leaves the nozzle.

Water actually accelerates inside the unit. What comes out isn't a stream — it's a concentrated, high-velocity jet that strikes surfaces with up to 200 bar (~2,900 PSI) — the same cleaning force as a £400 commercial pressure washer.
You twist it onto any standard garden hose, turn the tap on, and you're cleaning.
Why the Jetterix Is So Popular
Real customer footage. No editing. The Jetterix on a standard garden hose.
- Compatible with 99% of standard garden hoses — including all major UK brands (Hozelock, Kärcher, Karcher)
- No electricity required — runs entirely on the mains water pressure you already pay for
- Cleans driveways, patios, cars, decking, fences and outside walls — one tool, every outdoor surface
- Solid stainless-steel nozzle head with reinforced internals — built to outlast every pressure washer you've ever owned
- Uses up to 3× less water than a conventional hose for the same cleaning result
What Happens the First Time You Use It
Every Jetterix owner describes the same moment.
They point it at a surface they've been staring at for months — a stained drive, an algae-covered patio, a car with brake dust caked into the alloys — and within thirty seconds there's a visible line on the concrete where clean meets filthy.
It's not a subtle improvement. It's an immediate, undeniable transformation that makes every other cleaning method you've ever used feel a bit embarrassing in comparison.

From One Garage to Over 8,000 British Homes
The Jetterix is now used in over 8,000 households across the UK and Europe.
It has never been sold in a DIY shop. It has never been listed on Amazon. It has never run a TV campaign. Every unit moves through word of mouth — and a single official website.
That matters for one reason: no retail mark-up. No distributor margin. No advertising budget baked into the price.
Over 8,000 happy customers — stock is dwindling fast.

P.S. Hartley's insight is the same today as it was the morning he put the prototype together in his garage: you already have the pressure. The industry just never used it properly. For £49 today, you don't have to either. — M.S.
