Sun Joe SPX2598 Electric Pressure Washer
The Sun Joe SPX2598 electric pressure washer brings 2000 PSI and 1.65 GPM of cleaning power to your toughest outdoor jobs. We designed this model with a 40.6 fl oz onboard detergent tank so you can tackle greasy driveways, grimy siding, and mud-caked vehicles without stopping to mix cleaning solutions. The 14.5-amp motor plugs into any standard 120V outlet and eliminates the hassle of gas, oil changes, and pull-cord starts.
Our quick-connect wand accepts five color-coded nozzles (0°, 15°, 25°, 40°, and soap) that let you dial pressure from pinpoint blasting to gentle rinsing. The 20-foot high-pressure hose reaches second-story gutters and around SUVs without moving the unit, while the 35-foot power cord keeps you working without extension cords in most driveways. Total Stop System automatically shuts off the pump when you release the trigger to save energy and extend motor life.
Power & performance specs
Nozzle selection and spray patterns
The SPX2598 ships with five quick-connect nozzles stored in onboard holders so they’re always within reach. The red 0° nozzle concentrates water into a pencil-point stream for stripping paint or blasting concrete cracks. Yellow 15° and green 25° tips handle most deck and siding work, while the white 40° nozzle spreads a gentle fan for rinsing windows and vehicles.
The black soap nozzle draws detergent from the onboard tank and applies it at low pressure across large surfaces. We recommend starting every job with the widest spray pattern and stepping down to narrower angles only when needed — the tighter the angle, the more likely you are to etch wood or damage soft surfaces. Switch nozzles by pulling back the collar on the wand, popping out the current tip, and snapping in the new one until it clicks.
Onboard detergent system
The 40.6 fl oz detergent tank sits at the base of the unit and draws cleaning solution through a dedicated pickup tube when you attach the black soap nozzle. This bottom-load design keeps the center of gravity low and prevents tip-overs on uneven driveways. Pour any pressure-washer-safe detergent into the tank — we recommend biodegradable formulas for automotive and deck cleaning.
Apply soap in overlapping horizontal passes from bottom to top, let it dwell for three to five minutes without drying, then switch to a rinse nozzle and spray top to bottom. The tank holds enough solution to cover a two-car driveway or a 10×12 deck in one session. Rinse the tank with clean water after each use to prevent residue buildup.
Hose length and reach
The 20-foot high-pressure hose extends your effective cleaning radius to cover most residential jobs without repositioning the machine. We paired it with a 35-foot power cord so you can reach from a garage outlet to the far end of a driveway or around both sides of a full-size pickup. The hose uses standard M22 fittings compatible with replacement hoses and extension kits if you need extra length for second-story work.
Store the hose on the integrated side hook between uses to prevent kinks and UV damage. The wheels and top carry handle let you roll the SPX2598 across grass, gravel, and pavement without lifting, though the unit weighs just 19.2 pounds when empty and can be carried with one hand for stairs or tight spaces.

Common questions about the SPX2598
The SPX2598 produces a maximum of 2000 PSI at 1.65 gallons per minute. This pressure level handles most residential cleaning tasks including concrete driveways, wood decks, vinyl siding, vehicles, and patio furniture. It's strong enough to remove oil stains and mildew but gentle enough for painted surfaces when you use the wider spray nozzles.
You can use any pressure-washer-safe detergent in the 40.6 fl oz tank. We recommend biodegradable formulas designed specifically for electric pressure washers, as they rinse cleanly and won't harm plants or grass. Avoid using bleach or acidic cleaners unless the product label explicitly states compatibility with pressure washer pumps, since harsh chemicals can damage internal seals.
The power cord measures 35 feet from the unit to the plug. Combined with the 20-foot high-pressure hose, you get a total working radius of roughly 55 feet from your electrical outlet. This length covers most driveways and patios without needing an extension cord, though you can use a 12-gauge outdoor extension cord if you need extra reach for larger properties.
Yes, the Total Stop System shuts down the electric motor completely within one second of releasing the trigger. The pump stops running, eliminating noise and vibration between spray passes. When you squeeze the trigger again, the motor restarts instantly. This on-demand operation reduces energy use and prevents the pump from overheating during long projects with frequent breaks.
The SPX2598 offers 2000 PSI, while models like the SPX2599-MAX jump to 2800 PSI with brushless motors and larger detergent tanks. Higher PSI cuts cleaning time on heavy-duty jobs like stripping paint or removing deep-set stains, but the SPX2598 handles typical homeowner tasks at a lower price point. If you're cleaning decks, cars, and siding once or twice a month, 2000 PSI is sufficient.
Yes, the machine uses standard M22 fittings that accept aftermarket high-pressure hose extensions. Keep in mind that adding hose length reduces effective pressure at the nozzle — every 25 feet of additional hose drops PSI by roughly 5 to 10 percent. For most residential jobs, the included 20-foot hose provides enough reach without sacrificing cleaning power.
Disconnect the garden hose, drain residual water from the pump by squeezing the trigger until flow stops, and coil the high-pressure hose on the side hook. Store the unit in a garage or shed away from freezing temperatures, as ice can crack the pump housing. Wipe down the exterior and nozzles to remove detergent residue, and keep all five nozzles clipped into the onboard holders so they don't get lost.
