Independent Hands-On Review: We Tested the Jetterix for 14 Days on a Patio, Drive and Car
If you’ve been scrolling Facebook, Instagram or any of the major news sites over the past few weeks, you’ve almost certainly run into the same gadget we did: the Jetterix.
A small brass attachment. Screws onto a garden hose, supposedly turns the hose into a pressure washer. Glowing reviews in every gardening group. Ads everywhere. A stack of emails from readers asking us whether any of it is real.
So we checked it out ourselves. Ordered a Jetterix and spent 14 days putting it through real-world tests around the house — with no deference to the marketing claims. Here’s what we found.
The Jetterix delivers surprisingly close to what the ads promise.
For the typical cleaning jobs around a home — patio, drive, car, render — it’s noticeably more practical than a traditional pressure washer. No mains lead, almost no weight, lives in a kitchen drawer instead of the shed. Here are the test results, step by step:
Ordering & delivery
First hurdle: how reliable is the manufacturer? The Jetterix is sold exclusively through the official manufacturer’s site — not on Amazon, not at the DIY shed. That immediately makes a lot of readers sceptical (it made us sceptical too).
We placed our order Tuesday at 14:32. Payment options: PayPal or debit/credit card. Order confirmation hit our inbox within 9 minutes. Shipping notification with Royal Mail tracking number: the following morning. Delivered on Thursday — 2 working days after ordering.
Packaging: solid. Printed cardboard box, foam-padded inside. In the box:
- The Jetterix nozzle in solid brass (noticeably heavy in the hand)
- Full adapter kit for every common UK hose fitting
- Plain-English instructions (legible, no microscopic print)
- Quick-start sticker showing the nozzle settings
First impression: it feels like proper hardware, not a plastic toy. The brass is genuinely heavy compared to any DIY-shop plastic nozzle. Thread machining is clean — no burrs, no sloppy edges. Fitting it to the hose: unscrew your old spray head, screw the Jetterix on. We timed it — 19 seconds, no tools.
Test 1: 32 m² natural-stone patio with algae and moss in the joints
What we found
Classic post-winter state: the light stone flags were coated in a greyish-green film, moss was creeping out of every joint, and several spots had black patches from rotting leaves. We’d deliberately left one corner alone over winter to give us an honest test surface.
How the test went
Set the Jetterix to fan spray, held it about 25 cm off the surface, swept it across the flags at a steady pace. For the stubborn black spots we switched briefly to focused jet — that was enough to lift the leaf stains in a single pass.
The biggest surprise: the moss joints. We’d photographed them out of scepticism, convinced you’d need a wire brush. We were wrong. The water jet blew the moss almost completely out of the joints, without damaging the kiln-dried sand itself.
One concern for anyone worried about overspray: the fan setting is tight enough to work precisely — we didn’t have to cover anything or move any furniture.
32 m² completely clean in 14 minutes. No brushing, no detergent, no kneeling. Flags bright again, joints clear. The biggest positive surprise of the test.
Test 2: 18 m² concrete strip between house and shed
What we found
The harder test: a narrow concrete strip running along the side of the house between the wall and the garden shed. Little sun, lots of shade — perfect conditions for thick black algae. The surface was completely covered in a black-green coating — you couldn’t even see the concrete underneath.
How the test went
Here we wanted to know whether the Jetterix could handle extreme buildup. Went straight to focused jet mode, worked it slowly in lanes. The black coating started lifting immediately — you could see it dissolving the moment the spray hit. It looked as if the layer was being peeled back in sections.
What honestly surprised us: even with this much buildup, a single pass was enough. And after 13 minutes of work, none of our testers felt tired — the nozzle weighs almost nothing, which is a genuine difference from an 11-kg lance.
18 m² from black-green to light grey in 13 minutes. A single pass was enough. Works just as well on years of neglect as on light dirt.
Test 3: Family estate after a long motorway run
What we found
The test we approached most carefully. Pressure washers and car paintwork are always a touchy combination — get too close and the lacquer takes a hit. Our tester’s estate was covered in road grime after a long motorway run, with dried-on fly residue across the bonnet and front bumper, and dark brake dust on the alloys.
How the test went
About 30 cm of distance, softest fan-spray setting. Bonnet and front first, then sides, then alloys. Fly residue came off completely on the second pass. Brake dust took about four or five minutes per alloy and then the wheel was actually clean.
The point most relevant for anyone protective of their paintwork: paint check after drying showed zero scratches, zero scuffs, no white marks anywhere. The chrome badge on the tailgate wasn’t dented, the plastic on the bumpers showed no marks.
Anyone who’s tried this with a traditional electric pressure washer knows the sinking feeling. With the Jetterix, it’s genuinely relaxed.
Whole exterior clean in 11 minutes. No bucket, no sponge, no car wash. Paint check afterwards: flawless.
Three bonus surfaces we cleaned along the way
During the 14-day test we also used the Jetterix for a few jobs that came up naturally. Quick summary:
House render
14 m of lower render with algae streaks — back to uniform beige in 12 minutes. Fan spray, no need for focused mode.
Garage drive
28 m² concrete drive with oil stains and tyre marks. Focused jet, 14 minutes.
Block-paving entrance
Small block pavers at the garage entrance, darkly encrusted. Cleared in a single pass.
So how does the Jetterix actually work? — The physics
At this point in the test we wanted to understand it. How can an attachment with no motor, no pump and no power produce the same kind of pressure as an 11-kg machine with a high-output pump?
The answer is the Venturi effect — an 18th-century discovery every engineer learns, but almost no garden-tool maker actually implements properly. When water flows through a narrowing pipe, it accelerates. Same as when you put your thumb over the end of a garden hose — the jet suddenly shoots much further.
The Jetterix builds this effect into three sequential chambers, each machined more precisely than the last:
- Low-pressure intake (3–4 bar) — what comes out of any mains-fed hose.
- Precision venturi throat — milled to a tolerance of 0.1 mm. This is where the water accelerates to nearly 280 km/h.
- High-pressure output (up to 200 bar) — more than most pressure washers in the £350 class.
Why no cheap plastic DIY-shop nozzle pulls this off: First, the plastic can’t handle the pressure and cracks within weeks. Second, the precision of the venturi throat is what makes the whole thing work — with tolerances over 0.5 mm, the effect disappears. The Jetterix is milled from solid brass, which holds the pressure long-term.
At a standard hose pressure of 4 bar, the Jetterix produces an effective output of up to 207 bar — comparable to a mid-range £300 pressure washer.
What verified buyers say
Not wanting to rely solely on our own test, we cross-checked the verified-buyer reviews across the major rating sites. The picture is consistent: over 7,000 verified reviews, an average of 4.7 out of 5 stars. The few negative reviews almost all revolve around delivery times during peak demand — not the product itself.
Three reviews we picked out because we found them particularly telling:
★★★★★ „Sold our old £240 pressure washer the same week. The Jetterix does everything it did, only quieter, lighter, and without me having to drag a heavy machine out of the shed. Should be in every household.“
★★★★★ „I was sceptical because of all the advertising. But I ordered one, tested it, sold. For my terraced house this is exactly the right tool. Five stars, fully earned.“
★★★★★ „I have arthritis in my hands and haven’t been able to hold a heavy pressure washer for years. The Jetterix weighs almost nothing. I cleaned my paving myself yesterday for the first time in years.“
Common questions — what we asked the manufacturer
Yes. The pack includes a full adapter kit for every common UK hose fitting — Hozelock click-fit, ½″, ⅝″, ¾″ and 1″ BSP threads. We tested three different hoses — all fit instantly. Even hoses from the 1990s work fine.
Unscrew your old spray head, screw the Jetterix on. 20 seconds, no tools. If you can connect a garden hose, you can fit the Jetterix.
Yes — the Venturi effect amplifies whatever pressure is there. Even houses with old pipework and weak pressure (around 3 bar) still get the high-pressure effect. At normal mains pressure (4–6 bar), you’re well above any £300 pressure washer.
No. The Jetterix has an adjustable nozzle — from a soft fan spray (for cars, decking, plants) to a focused jet (for tough stains on stone or block paving). In our car test we saw zero paint damage.
Neither. The Jetterix is sold exclusively through the official manufacturer’s website. There’s a reason: cheap plastic knock-offs have already started appearing on Amazon and in DIY sheds, using the brand name but containing no brass at all — they crack within three weeks.
