If you are shopping for a Sun Joe 20V cordless pressure sprayer, the first thing to know is that the battery models in this lineup run on Sun Joe’s 24V platform, and they do two very different jobs. The IONMAX WA24C-LTE is a cordless washer that draws water from a bucket or container and sprays it through a nozzle, good for rinsing off a patio set, muddy boots or a bike where there is no outlet or tap. The 24V-GS-LTW is a 1-gallon chemical sprayer for weeds, fertilizer and plant treatment. If you need real cleaning force, the corded SPX205E-XT electric pressure washer is the one with a rated PSI, but it is not cordless.
This guide compares those three Sun Joe models, treating the choice like picking a loadout: runtime, output and range for each job. The two battery tools trade raw power for freedom from cords and hoses, while the corded washer brings far more pressure but ties you to an outlet and a garden hose. We compared listings, specifications and intended use, not hours of our own spraying, and we point out where a listing leaves a key number out.

Best for
Rinsing gear where there is no outlet
Pros
- 24V battery, up to 38 minutes
- Draws from a 5-gallon water source
- Twist nozzle from jet to fan
- Total Stop System saves battery
Cons
- Listing does not state PSI
- Light-duty 90W motor
The Sun Joe Cordless Electric Pressure Power Washer, model WA24C-LTE, is the fully portable option. It runs on a 24V lithium-ion battery with a 2.0Ah pack and charger included, and the listing quotes up to 38 minutes of runtime. Instead of connecting to a spigot, it is built around a 5-gallon water source, which is what makes it useful at a campsite, a cabin, a parking spot or a backyard with no tap close by.
The 90W motor drives up to 1.5 GPM according to the title. A twist nozzle switches between a pinpoint jet and a gentle fan, and the Total Stop System shuts off the pump when you release the trigger, which saves battery and reduces motor wear. It comes with a 20-foot high-pressure hose and an adjustable spray gun, weighs 9.5 pounds, and carries a two-year warranty.
The listing does not specify a PSI rating, and the item type describes it as a go-anywhere sink and shower spray washer kit. That is a fair hint about its strength: this is a rinsing and light cleaning tool, not a deck stripper. The listing also does not say whether a 5-gallon bucket is included, so plan to supply your own container.
This suits the reader who wants to hose down an outdoor gaming setup, wash off a mountain bike, rinse muddy gear after a LAN party campout or spray down a car on a balcony. It gives way to the SPX205E-XT when you need to lift set-in grime from concrete or wood. For a comparison with higher-voltage battery washers, our look at a 20V cordless pressure washer covers a stronger class.

Best for
Heavy patio, deck and car cleaning
Pros
- 1150 PSI rated, 1600 PSI max
- Up to 1.45 GPM
- 35-ft GFCI cord
- Extension wand and hose adapter
Cons
- Corded, not battery powered
- Needs outlet and garden hose
The Sun Joe Electric Pressure Washer SPX205E-XT is the power pick, but it is corded. An 11-amp motor delivers 1150 PSI rated pressure, 1600 PSI max, and up to 1.45 GPM. That is the kind of force that clears algae from a patio, grime from vinyl siding and road film from a car, jobs a battery sprayer cannot match.
It plugs in through a 35-foot GFCI power cord, which adds protection against shocks around water, and connects to a garden hose with the included adapter. You also get a 20-foot high-pressure hose, an extension wand and a twist nozzle that moves from gentle rinsing to a high-pressure jet. The Total Stop System shuts off the pump when the trigger is released. The feature text gives 13.7 pounds, the specifications 13.6, and there is a carry handle.
The trade-off is setup. You need an outdoor outlet and a hose tap within reach, and the listing does not mention a battery option. For a fixed backyard or driveway, that is rarely a problem, but it rules this model out for camping or a balcony without a tap.
This suits homeowners who want to deep-clean a deck before setting up an outdoor screen for movie nights, or wash the car and patio furniture every few weeks. It gives way to the WA24C-LTE when you are far from an outlet or water line. If you want a battery washer with more muscle, see our review of a 60V cordless power washer.

Best for
Garden weed and fertilizer spraying
Pros
- Up to 95 gallons per charge
- Telescopic 17.7-28.7 in. wand
- 360-degree adjustable nozzle
- Two-year warranty
Cons
- 1-gallon tank means frequent refills
- Not a cleaning washer
The Sun Joe 24V-GS-LTW IONMAX 24-Volt Chemical Sprayer is a different tool altogether. It is a 1-gallon, battery-powered sprayer meant for clearing weeds and vegetation, treating plant disease, and applying pesticide and liquid fertilizer. A kit version includes a 1.3Ah battery and a quick charger.
Its 10-watt motor pumps the liquid for you, so there is no hand-pumping to keep pressure up, and Sun Joe says it sprays up to 95 gallons per charge. The telescopic wand extends from 17.7 to 28.7 inches, and the nozzle end rotates 360 degrees so you can reach under leaves or along fence lines. The tank and body use plastic and alloy steel, and the warranty is two years under Sun Joe’s customer promise.
The 1-gallon tank is the main limit: with 95 gallons of spraying per charge, the battery will outlast many tank refills, so large yards mean frequent trips back to the mixing station. The listing does not specify spray pressure or flow rate, which is normal for chemical sprayers, since they aim for controlled coverage rather than force.
This suits a gardener, or a gamer who keeps a small yard or balcony garden, who wants to treat weeds without a pump sprayer. It is not a cleaning tool and should not be used with the same liquids you would put in a washer. For a broader look at battery sprayers, our cordless sprayer guide covers larger tanks.
- 1-gallon tank
- Up to 95 gallons per charge
- Telescopic 17.7 to 28.7 inch wand
- 360-degree adjustable nozzle

NOTES
Buying Tips for Sun Joe Cordless Pressure Sprayers
Match pressure to the job. A pressure washer’s PSI decides how much stuck-on dirt it can remove, while GPM decides how fast it rinses it away. The SPX205E-XT lists 1150 PSI rated pressure; the WA24C-LTE does not list PSI at all and is best treated as a strong rinse. If your main target is moss on pavers or grime on a wooden deck, the corded model is the honest choice.
Think about water and power access. The WA24C-LTE earns its place where there is neither an outlet nor a tap: it runs from a battery and a bucket. The SPX205E-XT needs both. The chemical sprayer needs neither during use, just a mixing spot for refills.
Plan battery time. The WA24C-LTE lists up to 38 minutes, which covers a patio set or a bike but not a long driveway. A second battery extends that if you already own the platform. The 24V-GS-LTW’s 95 gallons per charge is generous for a 1-gallon tank. If you are building out a Sun Joe yard kit, our Sun Joe reel mower review covers a battery-free way to keep the lawn tidy.
