The Kärcher 15-inch Surface Cleaner is our best driveway pressure washer surface cleaner for most compatible home machines. Its 15-inch path, 2.7 GPM ceiling and splash-control skirt make it the most balanced choice when your washer sits between 2600 and 3200 PSI.
How to choose a driveway pressure washer surface cleaner
A surface cleaner hides two spinning spray nozzles beneath a round deck. That fixed distance is the useful part: it makes overlapping passes more consistent than aiming a narrow wand at concrete. It is still not a cure for every driveway stain. Oil, old paint, loose joint sand and fragile decorative concrete need their own treatment or a cautious test patch.
For a typical residential driveway, a 15-inch deck is a sensible compromise. It covers far more area than a single nozzle without asking a modest washer to drive a very wide spray bar. Check the pressure range first, then the water flow. PSI is impact; GPM is what keeps a rotating bar moving and carries dirt away. A 1/4-inch quick-connect plug is also only useful when the end of your wand has the matching coupler.
This comparison separates three 15-inch tools by the machine they suit. Kärcher targets a defined 2600 to 3200 PSI, 2.7 GPM range. Westinghouse gives a broader 2500 to 3400 PSI ceiling in a compact, light attachment. SIMPSON is the sturdier choice for a higher-output gas washer, but it calls for at least 2200 PSI and 2.3 GPM and is cold-water only. None should be lifted while running, and each works best on level, hard surfaces.

Our driveway surface cleaner picks
Kärcher 15-inch Surface Cleaner
Kärcher earns the overall badge because its published operating window is unusually clear: 2600 to 3200 PSI and up to 2.7 GPM. That helps a homeowner rule it in or out before buying rather than assuming every 1/4-inch fitting behaves alike. The 15-inch deck uses two spinning nozzles, while its skirt is intended to reduce overspray around patios and driveway edges. At 3.8 pounds, it is also easier to guide than a heavier steel deck, and Kärcher says it can tackle hard vertical brick or stucco as well as flat concrete. Choose it for a correctly matched mid-output gas washer or capable electric unit. Its limitation is important: a machine above 3200 PSI or beyond 2.7 GPM is outside its stated match, so it is not the right shortcut for a powerful commercial-style washer. The consumer warranty is 90 days.
Pros
- Defined 2600 to 3200 PSI and 2.7 GPM compatibility range
- Splash-control skirt helps contain spray at driveway edges
- 3.8-pound deck is manageable for walls and flat concrete
Cons
- Not specified for washers above 3200 PSI or 2.7 GPM
- 90-day consumer warranty is shorter than Westinghouse coverage
Westinghouse 15-inch Surface Cleaner
The Westinghouse is the value pick for someone whose washer lands between 2500 and 3400 PSI and already has a 1/4-inch quick-connect wand. It keeps the same practical 15-inch cleaning width as the other choices, but its 15 by 15 by 4-inch form and four-pound weight make storage straightforward for a homeowner who will use it a few weekends each year. The listing describes it for gas and electric pressure washers and names flat decks, patios, driveways and walls among its intended jobs. That flexibility, plus a 180-day limited warranty, makes it a convincing simple attachment rather than a specialist accessory. It is the sensible choice when you want a light unit with a higher pressure ceiling than Kärcher. The tradeoff is that the listing gives no GPM operating range, so buyers should confirm their washer manual and avoid treating the universal connection as proof of hydraulic compatibility.
Pros
- 3400 PSI ceiling suits many homeowner gas pressure washers
- Four-pound 15 by 15 by 4-inch body stores without a bulky frame
- 180-day limited warranty doubles the stated coverage of the other picks
Cons
- No published GPM range to match against a washer manual
- Designed around flat surfaces rather than irregular stone or gravel
SIMPSON 80165 15-inch Steel Surface Cleaner
SIMPSON's 80165 is the better fit when the pressure washer is a substantial gas model and its output meets the stated minimum of 2200 PSI and 2.3 GPM. The 15-inch deck has a powder-coated steel shroud, stainless-steel nozzles and two rotating jets, with a 1/4-inch quick-connect plug. Its useful published envelope runs to 3700 PSI and 3.4 GPM, leaving more headroom than the Kärcher and Westinghouse choices for stronger machines. A supplied nozzle-cleaning tool is a practical inclusion because buildup can affect the spray pattern. Pick it for a large concrete drive where the washer, not the attachment, is already sized for sustained work. The real limitation is compatibility discipline: it is for cold water, no hotter than 140 F, and a small electric washer below the stated flow minimum is not its natural partner. SIMPSON provides a 90-day accessory warranty.
Pros
- 3700 PSI and 3.4 GPM maximum leaves room for stronger gas washers
- Powder-coated steel shroud and stainless nozzles address corrosion exposure
- Nozzle-cleaning tool is included for removing buildup from spray tips
Cons
- Requires at least 2200 PSI and 2.3 GPM for its stated operating range
- Cold-water limit of 140 F excludes hot-water cleaning setups
What matters before the first pass
Sweep away grit, leaves and loose stones before connecting any cleaner. Start on an inconspicuous patch, keep the deck flat and move at a steady walking pace. Fast passes can leave dirt behind; pausing in one spot can produce a visible change in clean concrete. Pre-treating a stain may be more effective than pressing harder, especially near paint, expansion joints or exposed aggregate.
The winner is therefore not simply the highest PSI number. Choose Kärcher for a documented mid-range match and useful splash control. Choose Westinghouse if a 2500 to 3400 PSI washer and longer limited warranty make the simpler package attractive. Choose the SIMPSON if your gas washer supplies the needed flow and you want steel construction with a 3700 PSI ceiling. In every case, inspect your washer manual for pressure, GPM and connector type before locking the plug into the wand.
FAQ
Can I use a 15-inch surface cleaner with an electric pressure washer?
Only if the cleaner's stated pressure and flow range includes the washer and the wand accepts a 1/4-inch quick-connect accessory. Kärcher specifically describes 2600 to 3200 PSI and up to 2.7 GPM, while SIMPSON calls for at least 2200 PSI and 2.3 GPM. Many smaller electric washers fall below those ranges, so read both manuals rather than relying on the connector alone.
Why does a driveway surface cleaner leave stripes?
Striping often comes from walking too fast, changing pace or using a cleaner that is poorly matched to the washer's water flow. Sweep debris first, overlap each pass slightly and keep the deck level. If a stripe persists, stop and inspect the two nozzles for debris. The SIMPSON includes a cleaning tool, but any blocked nozzle needs attention before continuing.
Are surface cleaners safe on pavers and decorative concrete?
They can be safer than a narrow wand because the deck holds the jets at a fixed height, but safety depends on the surface and the washer setting. Test a hidden area, avoid directing high pressure at loose joint sand, and do not use the tool on cracked or unstable material. A surface cleaner is intended for hard, level areas, not gravel or uneven stone.
