A mechanical engineer from Manchester spent 30 years optimizing water pressure systems. Then he walked into a hardware store, saw a £400 price tag, and decided the industry had been getting away with it for too long.

Adam Foster (58) didn't set out to disrupt a £10 billion
industry. He just wanted to clean his driveway without paying
for the privilege.
"The moss had taken over
completely. The patio looked like a forest floor." He'd been
putting it off for months - not because he didn't care, but
because every solution on the market felt like a rip-off. Rent a
machine. Buy a machine. Hire someone. Each option more expensive
and more annoying than the last.
So he did what
engineers do. He stopped looking at what was on the shelf and
started thinking about what was actually possible.
"Your
garden hose already produces pressure. The industry never
bothered to use it correctly."
Berger spent 30 years designing hydraulic systems for industrial
applications. He understood, better than almost anyone, how
water pressure works - and how badly the consumer market was
wasting it.
"A standard garden hose delivers water at
40 to 60 PSI. That's real pressure. The moment it hits a
conventional nozzle, 80% of that force disperses into the air
before it ever reaches the surface." He pauses. "That's not an
engineering problem. That's a business model."
Pressure
washer companies sell £400 machines because they've convinced
homeowners there's no other way. Berger knew there was.
After
several months of prototypes in his garage - testing geometries,
chamber configurations, nozzle angles - he produced something
that had no business existing at the price it would eventually
sell for.
The first real-world test was his own driveway. Twenty minutes.
What had taken years of weathering, moss, and accumulated grime
to build - gone.
"I was still cleaning when my
neighbor came over and asked what service I'd called." Berger
hadn't called anyone. He was holding a device the size of a
water bottle, attached to a garden hose he'd owned for six
years.
Within a week, three houses on his street had borrowed the
prototype. Within a month, he had more requests than he could
keep up with.
That prototype became
Triviacorn.
Triviacorn
is not a standard nozzle. Standard nozzles narrow the opening -
that produces a thinner stream, not more cleaning power. It's
the thumb-over-the-hose trick. More reach, barely more force.
Triviacorn
uses a precision-engineered dual-vortex chamber that
restructures water flow internally before it exits the nozzle.
The water accelerates inside the device. What comes out isn't
just a stream - it's a concentrated, high-velocity jet that hits
surfaces with 15 times the effective cleaning force of a
conventional hose.
No electricity. No motor. No
storage problem. No starting a gas engine on a cold morning. You
screw it onto any standard garden hose, turn on the water, and
you're done.
Compatible with 99% of standard garden hoses -
including all major UK brands
No electricity required -
runs entirely on existing water pressure
Cleans driveways, patios, cars, decks, fences, and siding
-
one tool, every outdoor surface
Marine-grade stainless steel construction -
built to last, not to be replaced
Saves up to 3x more water
than a conventional hose for the same cleaning result
Every
Triviacorn
owner describes the same moment. They point it at a surface
they've been looking at for months - a stained driveway, an
algae-covered patio, a car with brake dust caked into the wheel
wells - and within thirty seconds, there's a visible line on the
concrete where clean meets dirty.
It's not a subtle
improvement. It's an immediate, obvious transformation that
makes every other cleaning method you've ever used feel
embarrassing in comparison.
One user put it plainly:
"I cleaned a section of my driveway and then just stood there
for a minute. Twenty years of grime. Gone. I finished the whole
thing in 40 minutes and it looked like new concrete."
Triviacorn
is designed for anyone who wants to:
- Remove moss,
algae and dirt from patios or driveways
- Wash their car at
home without expensive equipment
- Clean garden furniture,
fences or exterior walls
- Enjoy pressure-washer
performance without paying hundreds of pounds
Triviacorn
is now used in more than 50,000 households across the UK and
Europe. It has never been sold in a retail store, never been
listed on Amazon, and has never run a TV campaign. Every unit
sold through word of mouth and a single official website.
That
matters for one reason: no retail markup, no distributor margin,
no advertising budget baked into the price. The £49 price tag is
what it costs - not what the market will bear."
⚠️ Current stock alert: Approximately 2,000 units remain in
the current production batch. Once sold out, the next delivery
is a minimum of 6 weeks away - and the 50% launch discount
will not be guaranteed on the next batch.
"I own a top-of-the-line Ryobi pressure washer. Paid £450 for it three years ago. The Triviacorn doesn't match it at the absolute top end - but for 90% of what I actually use it for? It's just as good. And I don't have to haul a 40-pound machine out of the garage every time. It pays for itself in convenience alone."
"My driveway hadn't been properly cleaned in five years. I kept saying I'd get to it. Took me 20 minutes with this thing. I'm not exaggerating. My neighbor came over and asked which company I'd hired. I showed her the Triviacorn. She ordered one that afternoon."
"My back has been shot for two years. Getting on my knees to scrub anything is not happening. This changed that completely. I just stand there and point it. The patio, the car, the fence - all done. No bending, no scrubbing, no pain the next morning."
Anyone ordering now can get Triviacorn for an introductory price of less than £50. A limited-time offer to enjoy its innovation and benefits at nearly half the regular price.
⚠️ Warning: As soon as the stock is sold out,
the promotion will end early.
Last year's experience: The
Qinux
Triviacorn
was already sold out by the morning.
