Sun Joe SPX3001 Electric Pressure Washer
Our SPX3001 electric pressure washer packs 2030 PSI and 1.76 GPM to tackle years of grime on driveways, siding, decks, patio furniture, and vehicles. The 14.5-amp motor delivers commercial-grade cleaning power without the noise, fumes, or maintenance of gas models.
Five quick-connect spray tips let you dial in the exact pressure for every surface — from gentle 40° for windows to concentrated 0° for stripping paint. The onboard reel keeps the 20-foot high-pressure hose organized, while dual 0.9-liter detergent tanks let you switch between soaps without refilling. Total Stop System automatically shuts off the pump when you release the trigger, extending motor life and saving energy between tasks.
Power & Performance Specs
Nozzle Selection & Surface Compatibility
The SPX3001 ships with five color-coded nozzles that snap on in seconds. The red 0° tip concentrates water into a pinpoint jet capable of stripping paint or rust from metal — use it sparingly on concrete and never on wood or vinyl. Yellow 15° works for stripping deck stain or removing heavy oil stains from driveways.
Green 25° handles most concrete and brick cleaning without etching, while the white 40° nozzle is gentle enough for windows, cars, and outdoor cushions. The black soap nozzle draws detergent from either onboard tank and applies a thick foam blanket. For vertical siding we recommend starting with the 40° tip on a test patch, then stepping down to 25° only if needed.
Detergent System & Cleaning Solutions
Both 0.9-liter tanks sit on top of the unit within easy reach. We designed them side-by-side so you can dedicate one to vehicle soap and the other to deck or concrete cleaner — no rinsing between jobs. The soap nozzle pulls from whichever tank you select via a simple valve switch.
Use only pressure-washer-rated detergents; household cleaners can clog the pump. For mildew on siding we recommend a diluted bleach solution (1 part bleach to 10 parts water in the tank). For grease on driveways, a citrus degreaser works best. Always apply soap from bottom to top, let it dwell for three to five minutes, then rinse top to bottom with a 25° nozzle to prevent streaking.
Total Stop System & Motor Protection
TSS automatically cuts power to the pump the moment you release the trigger. This prevents the motor from running dry and overheating during breaks between spraying. On long jobs — like washing an entire fence — TSS can add hundreds of hours to pump life compared to older models that run continuously.
The system also eliminates the kickback some users experience when squeezing the trigger on standard machines. Because the pump isn’t pre-pressurized, water flow ramps up smoothly rather than surging. If you’re switching nozzles mid-job, always release the trigger and let TSS disengage before twisting off the quick-connect fitting.

Common Questions About the SPX3001
The Sun Joe SPX3001 delivers 2030 PSI, which is ideal for concrete driveways and sidewalks. Use the 25° green nozzle for general dirt and the 15° yellow nozzle for oil stains or heavy grime. Start with the wider angle and move closer or switch tips if needed — holding the 0° nozzle too close can etch softer concrete.
Yes. Use the 40° white nozzle and keep the wand at least 12 inches from painted surfaces to avoid chipping clear coat. Apply soap with the black nozzle from the bottom up, let it sit for two minutes, then rinse top to bottom. Never aim the 0° or 15° tips at automotive paint, glass, or trim.
The SPX3001 connects to any standard garden hose via the inlet fitting. Your water source must provide at least 1.76 gallons per minute to keep the pump primed. If your faucet flow is lower than that, the pump may cycle on and off or lose pressure during operation.
The unit is rated for residential intermittent use — typically 30 to 45 minutes of active spraying, followed by a 15-minute cooldown. The Total Stop System reduces motor wear by shutting off the pump between trigger pulls, so you can leave it plugged in all afternoon as long as you're taking breaks between sections.
Use only detergents labeled for pressure washers. Household soaps and dish liquids create excess foam that can clog the pump and void your warranty. We recommend our Sun Joe branded wash concentrates, but any pressure-washer detergent diluted per the bottle instructions will work in both 0.9-liter tanks.
No. The SPX3001 is designed for cold water only — inlet temperature must stay below 104°F. Hot water can warp pump seals and crack the detergent tanks. If you need heated output for grease removal, look for a commercial hot-water model instead.
Disconnect all hoses, then squeeze the trigger to release residual water from the pump. Run our pump saver antifreeze through the inlet if temperatures drop below freezing. Store the unit in a garage or shed — the motor is splash-resistant but not weatherproof for months of outdoor exposure.
