No stripes, no splashback · review
A three-year warranty, and almost nothing else published.
Where this ends up Three bullets, no pressure rating, no material, no jet count — and a three-year warranty, which is six times what the next-best listing here offers. The least informative page on this shelf carries its longest guarantee.
That is the whole listing. Three bullets, and the description beneath them is about Greenworks’s range of trimmers, chainsaws and snow throwers rather than this product.
Three years is the longest warranty on this shelf by a factor of six.
Only two listings publish a term at all: both Greenworks heads at three years, and the Westinghouse 16.5” at $89.99 at “180-Day Limited Warranty”. Nine publish nothing.
What that cover is worth depends on what breaks, and on a surface cleaner it is always the same two things: the bearing and the swivel seal — the rotating joint carrying high-pressure water into a spinning arm. When the seal goes it leaks upward and sprays the operator, and stainless steel elsewhere does not help.
Three listings name that component. The JANZ has a “heavy-duty bearing”, the TOR “heavy-duty bearings”, the MEKOH a “fully sealed bearing” it claims will “prevent leaking and blocking, keeping you dry and safe”.
So three years on the component most likely to fail is a genuine asset.
It is also, on this page, the only thing you are told.
No pressure rating — neither maximum nor minimum. The maximum protects the tool; the shelf publishes 3000 PSI (Westinghouse 12”), 3200 (Hiclean, Kärcher), 3400 (Westinghouse 15”), 4000 (JANZ, TOR, JaxonBilt, Simpson), 4400 (Westinghouse 16.5”), and “2000+” (MEKOH).
No minimum, which is the figure that decides whether it works. A surface cleaner has no motor: its two nozzles are spun by the water leaving them, in reaction. Below a certain flow they turn too slowly, and the result is streaks or no rotation at all. Three listings publish a minimum — the Westinghouse 15” at 2500 PSI, the Simpson 16.5” at 2000 PSI and 2.5 GPM, the Kärcher 15” as a window of 2600–3200 PSI.
No flow figure. Five listings publish GPM: JANZ 1.8–3.7, Simpson 2.5–4, Kärcher up to 2.7, Westinghouse 12” max 2.3, MEKOH 2+. Flow is what spins the head, so it is arguably the more important of the two numbers.
No jet count. Eight listings here state one, and every one of them says two.
No material. Five publish stainless steel (Simpson, Westinghouse 16.5”, JANZ, TOR, JaxonBilt), the Hiclean an “all-metal rotating spinner”, the MEKOH PP plastic with brass.
No wheels, no skirt, no accessories, no speed claim.
1111 g and 305 × 130 × 305 mm.
Those two figures are informative in their way. A 12-inch head at 1111 g (39.2 oz) is squarely an electric-washer accessory — for comparison, the Hiclean 12” is 998 g (35.2 oz) and the Westinghouse 12” claims two pounds (907 g), while the stainless 14-inch heads from JANZ and JaxonBilt are 3175 g (112 oz) and the MEKOH 20” is 7860 g (277.3 oz).
Light heads and small discs belong on electric machines; that is the pattern the whole shelf follows, and the two 12-inch rivals here both say so explicitly. The Westinghouse 12” states it is “not intended for use with gas units” and the Hiclean that it is optimized “exclusively for electric”.
This listing does not say it. The weight and the width say it for them.
Every listing on this shelf that states a jet count says two. So at equal flow, a wider head spreads the same water over a bigger circle — energy per square inch falls as the disc grows.
Wider is not stronger. Wider needs more flow.
Which is why the three 12-inch heads here are the ones aimed at electric washers, and the MEKOH 20” sets a floor of “2000+ PSI & 2+ GPM”.
A 12-inch swathe is more passes on a driveway. It is also the width that fits a porch step, a narrow path and the gap between a car and a garage wall — the Westinghouse 12” makes exactly that case: “ideal for hard-to-reach spots, tight corners or small spaces; great for porch steps, deck stairs or narrow walkways”.
At 1111 g (39.2 oz) it is also light enough to hold against a fence, which nothing above about two kilos is.
Westinghouse PWSC12, $26.09 — eight dollars less, and publishes 3000 PSI, 2.3 GPM, dual rotating jets, two pounds, a splash-free brush skirt, no gas, and a 4× faster claim.
Hiclean, $39.99 — five dollars more, and publishes up to 3200 PSI, three rotating wheels, an “all-metal rotating spinner” against “plastic spinners that often break”, a list of compatible brands, and the best technical argument on this shelf: that a head optimized for electric washers spins faster than a universal one, because a universal one must survive 4000 PSI and therefore carries heavier internals.
This, $34.99 — publishes a width, a fitting and three years.
If the warranty is the purchase, this is the only listing offering one at this width. If the specification is the purchase, it is the weakest page here.

From this listing, you cannot — and that is its real weakness. It publishes "1/4-inch quick connect compatible with most pressure washers" and no pressure figure of any kind, neither maximum nor minimum. What you would want to check: the maximum, which protects the tool — the shelf publishes 3000 PSI (Westinghouse 12"), 3200 (Hiclean, Kärcher), 3400 (Westinghouse 15"), 4000 (JANZ, TOR, JaxonBilt, Simpson) and 4400 (Westinghouse 16.5"). And the minimum, which decides whether it works at all, because a surface cleaner has no motor and its nozzles are spun by the water leaving them. Below a certain flow they turn too slowly and you get streaks. Only three listings here publish a minimum: the Westinghouse 15" at 2500 PSI, the Simpson 16.5" at 2000 PSI and 2.5 GPM, and the Kärcher 15", which gives a window — 2600 to 3200 PSI — so a 3600 PSI machine is above its range. Practically: this is a 12-inch head weighing 1111 g (39.2 oz), which is the profile of an electric-washer accessory. Treat it as one.
It is the longest on this shelf by a wide margin, and worth understanding what it covers. Only two listings publish a term at all: both Greenworks heads at 3 years, and the Westinghouse 16.5" at $89.99 at "180-Day Limited Warranty". Nine listings publish nothing. What fails on a surface cleaner is the bearing and the swivel seal — the rotating joint that carries high-pressure water into a spinning arm. When it goes, it leaks upward and sprays the operator, and no amount of stainless steel elsewhere helps. Three listings address that part directly: the JANZ with a "heavy-duty bearing", the TOR with "heavy-duty bearings", the MEKOH with a "fully sealed bearing" it claims will "prevent leaking and blocking". So a three-year warranty on the component most likely to fail is a real asset — provided the claim process is workable. The honest summary: this listing tells you almost nothing about the tool and rather a lot about what happens if it breaks, which is the inverse of everything else here.
Eight dollars cheaper, and far more published. The Westinghouse PWSC12 gives 3000 PSI max, 2.3 GPM max, dual rotating jets, a stated two pounds, a brush skirt described as splash-free, an explicit statement that it is not for gas washers, and a 4× faster claim. This gives a width, a fitting and a warranty. For the same twelve-inch width there is also the Hiclean at $39.99, which publishes up to 3200 PSI, three rotating wheels, an "all-metal rotating spinner" against "plastic spinners that often break", and the clearest technical argument on this shelf — that a head optimized for electric washers spins faster than a universal one, because a universal one must be built heavy enough to survive 4000 PSI. So among the three 12-inch heads: the Westinghouse is cheapest and best documented, the Hiclean adds metal internals and three wheels, and this one adds three years of cover. If the warranty is what you are buying, it is the only one offering it.
