Sun Joe Cordless Pressure Washer – 24V iON+ Portable Cleaning System
We built our Sun Joe cordless pressure washer to eliminate every friction point of traditional cleaning. The 24V iON+ battery system powers a 350-watt motor that delivers 550 PSI through a compact wand you can carry with one hand. Draw water from any bucket, sink, or pool—no garden hose required.
Perfect for spot-cleaning patio furniture, rinsing muddy bikes, washing vehicle interiors, or scrubbing grill grates. The five-liter onboard tank holds enough water for quick jobs, and when you need more capacity, the 20-foot suction hose pulls from any container. Charge the lithium-ion battery in 90 minutes, then clean for up to 22 minutes of continuous runtime.

Battery System & Runtime Details
Our 24V iON+ lithium-ion battery uses the same cell architecture across our entire cordless tool line, so if you already own a Sun Joe hedge trimmer or pole saw, you can swap batteries between tools. A full charge provides approximately 22 minutes of trigger-on spray time at maximum pressure—enough to wash two mid-size sedans, clean a 12×12 deck, or rinse four patio chair sets.
The intelligent battery management system monitors cell temperature and automatically throttles output if it detects overheating, then resumes normal operation once cooling occurs. Charge time from empty to full is 90 minutes using the included wall charger. We include one battery with every unit; additional batteries are sold separately if you need back-to-back runtime for larger properties.
Water Source Flexibility & Tank Capacity
The five-liter onboard reservoir sits behind the motor housing and fills through a wide-mouth cap in under 60 seconds. For jobs requiring more water, attach the 20-foot suction hose to draw from any bucket, cooler, rain barrel, or utility sink—no pressurized tap connection needed. The self-priming pump pulls water vertically up to six feet, so you can place a five-gallon bucket on the ground and work from a ladder.
This design makes our sun joe cordless pressure washer ideal for properties without exterior spigots, RV owners cleaning at campsites, or anyone who needs to rinse equipment stored far from the house. The intake filter catches debris before it reaches the pump, and you can rinse the filter under a faucet every few uses to maintain flow rate.
Nozzle Selection & Spray Patterns
Quick-Connect Tip System
We include three color-coded nozzles that lock into the wand with a quarter-turn bayonet fitting. The red 0° nozzle concentrates 550 PSI into a pencil-thin jet for stripping caked mud from wheel wells or blasting mortar residue from brick. The yellow 15° fan works for general cleaning—siding, fences, outdoor cushions. The white 40° wide-angle tip covers large flat areas like garage floors or driveways without leaving zebra stripes.
Foam Cannon Attachment
The included foam cannon draws from its own soap reservoir and mixes detergent with air to create thick suds. We recommend it for pre-soaking vehicles before rinsing or applying deck cleaner to railings. Soap flow adjusts via a dial on the bottle cap, and the cannon body disassembles completely for cleaning after each use.

Common Questions About the Sun Joe 24V Cordless Washer
Yes—the 550 PSI output is safe for automotive paint, glass, and trim when you use the 40° wide-angle nozzle. We recommend pre-soaking with the foam cannon, then rinsing from top to bottom. Avoid the 0° nozzle on painted surfaces, as the concentrated stream can chip clear coat if held too close.
One full battery charge provides enough runtime to wash a mid-size sedan twice, or one large SUV with detailing. For best results, work in shade to prevent soap from drying on the surface before you rinse.
You'll get approximately 22 minutes of continuous trigger-on spray time at maximum pressure. In real-world use—where you release the trigger between passes—most users report 30 to 35 minutes of total working time before the battery depletes.
Charge time from empty to full is 90 minutes. The battery uses the same 24V iON+ platform as our other cordless tools, so if you own multiple Sun Joe products you can swap batteries mid-job.
No garden hose required. The unit has a five-liter onboard tank you fill from any tap, and we include a 20-foot suction hose that draws water from buckets, coolers, or rain barrels. The self-priming pump can lift water up to six feet vertically, so you can place a five-gallon bucket on the ground and work from a ladder.
This design makes the sun joe cordless pressure washer ideal for job sites without water access, RV camping, or cleaning areas far from your house.
The red 0° nozzle produces a pencil-thin jet for stripping stubborn grime from concrete or blasting mud from tire treads. The yellow 15° fan is our all-purpose tip—use it for siding, fences, vehicles, and general cleaning. The white 40° wide-angle nozzle covers large flat surfaces like decks or garage floors without leaving streaks.
All three lock into the wand with a quarter-turn bayonet fitting and swap in under five seconds. We also include a foam cannon attachment that replaces the nozzle entirely for soap application.
Yes—the 20-foot suction hose works with any freshwater source including pools, ponds, streams, or lakes. The intake filter catches debris before it enters the pump, though we recommend rinsing the filter after use in natural water sources to remove silt and organic matter.
Avoid saltwater, as it will corrode internal seals over time. If you accidentally use saltwater, flush the system immediately by running five liters of fresh water through the pump with the spray wand open.
It handles light deck maintenance—rinsing pollen, dirt, and leaf debris—very well. For deep cleaning or stripping old stain, you'll want our corded SPX3000 model with 2030 PSI. The cordless unit's 550 PSI works best for regular upkeep between deeper cleanings.
If you apply deck cleaner solution with the foam cannon and let it sit for ten minutes before rinsing, this unit will restore most composite and treated-wood decks to near-original appearance without the noise and setup time of a gas or corded electric model.
We back the 24V-PP350-LTE with a two-year warranty covering the motor, pump, battery, and charger against manufacturing defects. Wear items like nozzles, hoses, and triggers are covered for 90 days.
