No stripes, no splashback · review
Fifteen inches, an extension in the box, and three years of cover.
Where this ends up A fifteen inch head with an extension included and three years of cover, published in three bullets that give no pressure rating, no material and no jet count. Twenty-five dollars above its own twelve inch sibling for three inches and a wand.
Three bullets, and the description beneath them is about Greenworks’s range of trimmers, chainsaws and snow throwers rather than this product.
“Extension Included” in the title, and only three other listings on this shelf ship one.
The JANZ 14” has “2 x extension wands”. The TOR 14” has “2 Extension Wands (15” each)”. The JaxonBilt 14” has two 15-inch wands and states the point: “no bending required”.
Everything else here — both other Westinghouse heads, the Kärcher, the Simpson, the MEKOH, the Hiclean, and this maker’s own 12” — expects you to use the wand your washer came with.
That matters more than it reads. Most washers ship a wand short enough that a surface cleaner sits well below comfortable reach, and a driveway is half an hour of work. Without an extension you spend it stooped, with the tool pulling away from you.
It is a cheap part to buy separately. It is also one more thing to match to a 1/4 inch quick-connect, and having it in the box removes that step.
Three years is the longest warranty on this shelf, shared only with this maker’s own 12-inch head.
The only other term published anywhere here is the Westinghouse 16.5” at “180-Day Limited Warranty”. Nine listings publish nothing at all.
What breaks on a surface cleaner is always the same: the bearing and the swivel seal — the rotating joint carrying high-pressure water into a spinning arm. When the seal hardens it leaks upward and sprays the operator, and stainless steel elsewhere does not help.
Three listings name that region directly. A “heavy-duty bearing” on the JANZ, “heavy-duty bearings” on the TOR, a “fully sealed bearing” on the MEKOH claimed to “prevent leaking and blocking”. The Hiclean approaches it from the other side with an “all-metal rotating spinner… designed to last longer than typical plastic spinners that often break”.
So three years of cover on that component is a real asset — and on this page it is one of only three things you are told.
2445 g, and weight on this shelf is argued in both directions because it matters differently for different jobs.
The published figures: Hiclean 12” 998 g (35.2 oz) · Greenworks 12” 1111 g (39.2 oz) · Kärcher 15” 1724 g (60.8 oz) · Westinghouse 15” a stated 4 lb · this 2445 g (86.2 oz) · JANZ and JaxonBilt 14” 3175 g (112 oz) · Simpson 16.5” 5375 g (189.6 oz) · MEKOH 20” 7860 g (277.3 oz). The Westinghouse 12” claims two pounds.
For driveways, the JANZ 14” has the physics right: “It is heavy enough not to rise up under high pressure.” The nozzles point down, so by reaction the jets lift the head — too light on a strong machine and it skates and chatters, and a head not sitting flat makes stripes.
For walls, the opposite. The Westinghouse 12” calls two pounds “an easy lift for vertical use on walls and fences”; the Kärcher at 1724 g (60.8 oz) claims “hard vertical surfaces like brick and stucco”. Nobody holds the MEKOH’s seventeen pounds against a gable end.
At 2445 g (86.2 oz) this sits between the two — heavy enough to stay down on a domestic machine, light enough to lift onto a fence for a short stretch.
Every listing on this shelf that states a jet count says two. Nobody publishes three.
So at equal flow, a wider head spreads the same water over a bigger circle, and energy per square inch falls as the disc grows. Wider is not stronger. Wider needs more flow.
That pattern runs through the whole shelf. The three 12-inch heads are the ones aimed at electric washers — the Westinghouse 12” states “not intended for use with gas units”, the Hiclean that it is “exclusively for electric”. The 20-inch MEKOH sets a floor of “2000+ PSI & 2+ GPM”.
Fifteen inches needs a mid-range machine to feed it properly. Both 15-inch rivals say which: the Kärcher publishes 2600–3200 PSI, up to 2.7 GPM, and the Westinghouse 15” publishes 2500 to 3400 PSI.
This listing publishes neither, so the width is a guess against your own washer. The 2445 g (86.2 oz) is the clue — that is a mid-range domestic head, not a contractor’s.
No pressure rating. Neither ceiling nor floor, where nine other listings give at least one.
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 useful of the two numbers.
No jet count, where eight listings here state one and all eight say two.
No material. Five publish stainless steel (JANZ, TOR, JaxonBilt, Simpson, Westinghouse 16.5”), the Hiclean an all-metal spinner, the MEKOH PP plastic with brass.
No wheel count. Four listings publish four (JANZ, TOR, JaxonBilt, MEKOH); the Hiclean publishes three — and three points define a plane, so a tripod cannot rock on uneven concrete.
No skirt, which every other substantive listing here describes, and which does two jobs: holding the nozzle height constant to prevent streaks, and containing the spray so grit does not land on your car.
No inlet filter, which the JANZ and TOR have — and whose absence the Simpson concedes by shipping a nozzle-cleaning needle instead, noting that “naturally-occurring buildup can gather in the nozzles over time”.
No maximum water temperature, where the Simpson publishes “only for cold water use; max temp 140° F” and the MEKOH claims hot and soapy water are both acceptable.
No speed claim, which is at least a restraint the rest of the shelf does not show: the multipliers elsewhere run 4×, 5×, 8× (against other surface cleaners) and 10×.

Because it decides whether you clean standing upright or bent over, and only three listings on this shelf include one. The title here says "Extension Included". The JANZ 14" at $39.99 ships "2 x extension wands", the TOR 14" at $37.99 "2 Extension Wands (15" each)", and the JaxonBilt 14" at $59.99 "two 15” extension wands, no bending required". Everything else — both other Westinghouse heads, the Kärcher, the Simpson, the MEKOH, the Hiclean and this maker’s own 12" — expects you to use the wand your washer came with, which on most machines is short enough that a surface cleaner sits well below comfortable reach. The practical consequence of going without: a driveway takes half an hour, and you spend it stooped with a tool pulling against you. An extension is a cheap part to buy separately, but it is one more thing to match to a 1/4 inch quick-connect fitting. Having it in the box removes that.
The ability to check whether it suits your machine, which is the first thing you should establish. This listing publishes "1/4-inch quick connect compatible with most pressure washers" and no pressure figure at all. The maximum protects the tool, and the shelf publishes 3000 PSI (Westinghouse 12"), 3200 (Hiclean, Kärcher), 3400 (Westinghouse 15"), 4000 (JANZ, TOR, JaxonBilt, Simpson) and 4400 (Westinghouse 16.5"). The minimum decides whether it works at all: a surface cleaner has no motor, and its nozzles are spun by the water leaving them, so below a certain flow they turn too slowly and leave stripes. Three listings publish a floor — 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, which means a 3600 PSI machine is above its range. What this listing does give you is 2445 g (86.2 oz) at 15 inches, which is the profile of a mid-range domestic head — comparable to the Kärcher 15" at 1724 g (60.8 oz) and the Westinghouse 15" at a stated four pounds, both of which are built for the 2500–3400 band.
For three inches of width and an extension wand, and that is the whole difference between the two listings — both publish the same three bullets, the same quarter inch fitting and the same three year warranty. The width question has a catch worth knowing. 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, and energy per square inch falls as the disc grows. Wider is not stronger; wider needs more flow. Neither Greenworks listing publishes a flow requirement, so you cannot tell whether your washer can feed 15 inches properly. The weights hint at it: 1111 g (39.2 oz) for the 12 inch, 2445 g for this. For comparison the JANZ 14" at $39.99 — five dollars less than this — publishes 2000 to 4000 PSI, 1.8 to 3.7 GPM, stainless steel, two nozzles, four wheels, an inlet filter and a seven-item kit with two spare nozzles. On specification that is the better purchase. On warranty, this is the only one offering any.
