Sun Joe SPX2688-MAX Electric Pressure Washer
We designed the Sun Joe SPX2688-MAX to deliver professional-grade cleaning performance without the noise, fumes, or maintenance of gas-powered units. This electric pressure washer generates 2300 PSI at 1.2 GPM, providing the muscle you need to strip away years of grime from concrete, siding, patio furniture, and vehicles.
The SPX2688-MAX comes ready to tackle any outdoor cleaning project with five quick-connect spray tips that let you switch from a gentle rinse to a concentrated jet in seconds. Our 34-inch extension wand puts extra reach between you and the mess, while the onboard 20 oz. detergent tank feeds soap directly into the stream for one-step cleaning. The Total Stop System automatically shuts off the pump when you release the trigger, extending motor life and saving energy between tasks.
Key specs & performance details
Nozzle selection & spray patterns
The SPX2688-MAX includes a complete set of color-coded quick-connect nozzles that snap onto the wand in one motion. The red 0° tip concentrates the full 2300 PSI into a pinpoint jet for stripping paint, cutting through heavy oil stains, or blasting away stubborn rust—use it sparingly and keep the tip at least 12 inches from any surface to avoid damage.
Our 15° yellow nozzle fans the stream slightly for intense cleaning on concrete driveways and sidewalks, while the 25° green tip handles general-purpose jobs like washing vinyl siding, wooden decks, and garden tools. The 40° white nozzle spreads the spray wide for delicate surfaces such as car paint, windows, and wicker furniture. The black soap nozzle draws detergent from the onboard tank and applies it at low pressure, priming surfaces before you switch to a cleaning tip.
Power source & cord management
The SPX2688-MAX runs on a 14.5-amp motor that plugs into any grounded 120V household outlet—no gas, no oil changes, and no pull-cord hassles. We built the unit with a 35-foot heavy-duty power cord, so you can position the washer near a spigot and still reach most of your yard without hunting for an extension cord.
Pair that electrical reach with the included 20-foot high-pressure hose, and you have 55 feet of total operating radius from the outlet. For jobs beyond that range, use a 14-gauge or heavier outdoor extension cord rated for at least 15 amps; lighter cords will starve the motor and trip your breaker under load. We recommend coiling the power cord loosely after each use and storing it on the integrated cord wrap to prevent kinks that can damage the insulation over time.
Total Stop System & motor protection
Every time you release the trigger, our Total Stop System immediately cuts power to the pump motor. This on-demand control saves electricity, reduces wear on internal seals, and keeps the pump from overheating during long projects where you pause frequently to reposition the wand or move an obstacle.
The TSS also acts as a safety lockout: the motor will not restart until you squeeze the trigger again, preventing accidental spray when you set the wand down or hand it to someone else. Because the pump only runs while you’re actively spraying, you’ll notice the SPX2688-MAX stays cooler and quieter than older models that idle continuously once switched on.

Common questions about the SPX2688-MAX
The red 0° nozzle can strip paint, but we recommend using the 15° or 25° tip for most deck cleaning to avoid gouging the wood. Hold the wand at a 45-degree angle and keep it moving to prevent damage.
For stripping old stain before refinishing, the yellow 15° nozzle at close range will lift most finishes without splintering the grain. Always test on an inconspicuous board first.
The SPX2688-MAX is designed for cold water only—maximum inlet temperature is 104°F. Using hot water from a tank-style heater can damage the pump seals and void the warranty.
If you need heated cleaning power, consider a gas-powered hot-water model or use a detergent formulated to cut grease in cold water.
Any standard garden hose with a ¾-inch male fitting will connect to the washer's inlet. We recommend a hose rated for at least 50 PSI to ensure steady flow to the pump.
Make sure the hose has no kinks and that your spigot delivers at least 1.5 gallons per minute. The pump cannot generate full pressure if the water supply is restricted.
The Total Stop System lets the motor rest whenever you release the trigger, so you can work all day as long as you pause occasionally. During active spraying, limit continuous run time to 30 minutes, then let the unit cool for 10 minutes.
If the motor feels hot to the touch or you notice a drop in pressure, shut off the washer and allow it to cool completely before resuming.
Only use detergents labeled as pressure-washer safe. Household dish soap and automotive car-wash concentrates often create excessive foam that can clog the pump and damage internal seals.
Sun Joe offers a line of biodegradable cleaning solutions formulated for pressure washers, or you can use any commercial pressure-washer detergent that matches your surface type.
Yes, the 34-inch extension wand and 2300 PSI output will reach second-story siding from the ground in most cases. For tall peaks or gutters above 20 feet, you may need to work from a ladder or add an aftermarket extension.
Use the 25° green nozzle for vinyl or wood siding and the 40° white nozzle for painted surfaces to avoid stripping the finish.
After every session, disconnect the garden hose and squeeze the trigger to release residual pressure. Run the pump for 30 seconds to purge water from the lines, then switch off and unplug the unit.
Rinse the detergent tank with clean water if you used soap, and store the washer in a freeze-protected location. In winter, add pump antifreeze to prevent ice damage if you cannot store the unit indoors.
