Who Is This Attachment Best For? 🏠 Homeowners cleaning driveways, sidewalks, and garage floors 🪵 Anyone cleaning decks, patios, pavers, and brick surfaces 🚗 Users wanting to clean parking areas and concrete pads quickly ⚡ Anyone who wants 4× faster cleaning vs. a standard spray nozzle 🚫 Users frustrated by streaking and uneven results from wand-only washing 🔌 Owners of any Sun Joe® SPX Series or compatible pressure washer Setup & Attachment 🚫Always switch off your pressure washer and depressurize before attaching or removing the SPX-SC14. Never change attachments while water is flowing or the trigger is squeezed. Switch off the pressure washer Turn the motor switch to OFF (0). Squeeze the trigger gun to release all residual pressure in the hose. Remove the existing nozzle or wand attachment Pull back the brass Quick-Connect collar on your pressure washer's spray lance and remove the current nozzle. Connect the SPX-SC14 extension wand Pull back the Quick-Connect collar on your spray lance and insert the 1/4-inch QC male end of the SPX-SC14 extension wand. Release the collar — it will click securely into place. Confirm the connection is locked Gently tug the wand to confirm it is fully seated and locked. A loose connection will cause leaks at the joint. Place on the surface and start cleaning Set the SPX-SC14 flat on the surface to be cleaned. Turn on the water, start the pressure washer, and begin cleaning — moving the unit slowly and steadily for best results. Usage Tips For Best Cleaning Results Move the SPX-SC14 slowly and steadily — rushing reduces contact time and cleaning effectiveness Overlap each pass by 1–2 inches to avoid leaving uncleaned lines between rows For very heavy buildup or oil stains, make a second pass after the first Apply a pressure washer-rated detergent to the surface first, let it dwell for 2–3 minutes, then clean with the SPX-SC14 for deep stain removal Keep the housing flat and level with the surface — tilting reduces the cleaning path and can cause uneven results For stubborn spots, hold the unit stationary for 1–2 seconds over the stain before moving forward Surface Suitability Concrete and asphalt — ideal; handles heavy staining and oil buildup Paving stones and brick — excellent; uniform pressure won't dislodge mortar Composite and wood decking — use at lower pressure settings; do not use on soft or weathered wood Tile and stone patios — excellent for algae and mildew removal Garage and workshop floors — excellent for grease, grime, and rubber tire marks ⚠️Do not use on soft or delicate surfaces such as painted wood, vehicle paint, soft vinyl siding, or rubber membranes. The rotating spray jets are high-powered and can cause damage to surfaces not rated for high-pressure cleaning. Cleaning Pattern Start at the far end Begin at the edge farthest from your water supply so you push dirty water away from yourself as you work back. Work in straight rows Move the SPX-SC14 in overlapping horizontal rows across the surface width. Rinse finished sections Swap to a standard nozzle (40°) to rinse loosened dirt off the cleaned surface toward a drain. Care & Maintenance 🚫Always switch off and depressurize the pressure washer before removing, inspecting, or cleaning the SPX-SC14. After Every Use Flush the unit After cleaning, run clean water through the attachment for 30 seconds to flush out any detergent or debris from the spray arm and housing. Inspect the spray nozzles Check the two rotating spray jet openings for any blockage. Use the needle clean-out tool from your pressure washer (if included) to clear any obstructions. Rinse the housing exterior Wipe down or rinse the housing and wheels to remove debris and grime. Disconnect and store Remove from the spray lance, allow to drain fully, and store in a dry location. Periodic Checks Inspect the quick-connect fitting for wear, corrosion, or cracking — replace if damaged Check the spray arm rotates freely — a blocked or stiff arm reduces cleaning performance Inspect the wheel axles for debris buildup that could impede movement Verify the housing seal and o-rings are intact — any cracks can cause pressure loss and leaking Storage Store indoors in a dry location away from freezing temperatures Always drain completely before storing — residual water in the spray arm can freeze and crack internal components Store the extension wand attached or coiled nearby to prevent fitting damage Do not store under heavy objects that could deform the housing or wheels 🚫Do not store where temperatures fall below 32°F (0°C) with water remaining inside. Freeze damage is not covered under warranty.

The SPX-SC14 uses a standard 1/4-inch quick-connect fitting, which is compatible with virtually all Sun Joe® SPX Series pressure washers and most other electric and gas pressure washers that use a standard 1/4-inch QC spray lance. If your pressure washer uses this fitting size, the SPX-SC14 will attach. If unsure, check your pressure washer's wand connector size or call 1-866-SNOWJOE (1-866-766-9563). Can I use the SPX-SC14 with the SPX1500-Q? Yes. The SPX1500-Q uses a standard 1/4-inch quick-connect spray lance, and the SPX-SC14 attaches directly to it. Simply remove the existing nozzle from the SPX1500-Q's spray wand and insert the SPX-SC14 extension wand until it clicks into place. The SPX1500-Q's 1500 PSI rated pressure is well within the SPX-SC14's 4000 PSI max rating. How is this different from just using a spray nozzle? A standard spray nozzle delivers a single directional stream that covers a narrow path and often leaves streak marks as you sweep it back and forth. The SPX-SC14 uses two counter-rotating nozzles inside a housing that evenly distributes pressure across a full 13-inch diameter path simultaneously — delivering consistent, streak-free results up to 4× faster, with far less effort and arm fatigue. Can I use detergent with the SPX-SC14? Yes. For best results on stained or grimy surfaces, apply a pressure washer-rated detergent directly to the dry surface and allow it to dwell for 2–3 minutes before using the SPX-SC14 to clean. Always rinse with clean water after using detergent to prevent residue buildup. Never use acids, bleach, or solvents with the SPX-SC14 — these can damage internal components. Can I use this on a wood deck? The SPX-SC14 can be used on composite decking and pressure-treated hardwood, but use with caution. High-pressure washing can raise wood grain, strip finish, and damage soft or weathered wood. If using on wood, operate your pressure washer at a lower pressure setting and keep the unit moving — never hold it stationary on wood surfaces. Test a small hidden area first. The spray arm isn't spinning. What should I do? The most common cause is a clogged spray nozzle. Disconnect the SPX-SC14 from the wand, depressurize the system, and use a fine needle or the needle clean-out tool from your pressure washer to clear both spray jet openings. Also confirm your pressure washer is operating at adequate pressure — very low pressure may not generate enough flow to spin the arm. If the arm is physically stuck and clearing the nozzles doesn't help, contact 1-866-SNOWJOE for support. How do I get streak-free results? Move the SPX-SC14 slowly and steadily — rushing is the most common cause of streaking. Overlap each pass by 1–2 inches so adjacent strips blend cleanly. Keep the housing flat and parallel to the surface at all times. Ensure both spray nozzles are clear and unobstructed. After cleaning, rinse the entire surface with a 40° nozzle to wash away loosened dirt. Can I use this with a gas pressure washer? Yes — the SPX-SC14 is rated up to 4000 PSI and 4.0 GPM, making it compatible with many residential-grade gas pressure washers that use a standard 1/4-inch quick-connect lance. Verify your gas washer's output PSI is within the 4000 PSI max rating before use. How do I register my product?

No. The SPX-SC14 has a 13-inch cleaning path diameter and weighs 6.8 lbs, while the SPX-SC17 has a larger 17-inch cleaning path and weighs 9.7 lbs (with a 15.9-inch wand). Both share the same 4000 PSI / 4.0 GPM rating and universal 1/4-inch quick-connect fitting. The SPX-SC14 is more compact and agile — ideal for tighter spaces, patios, and decks. The SPX-SC17 covers more area per pass and is better suited for large driveways and open surfaces.
