Sun Joe SPX3000 vs SPX3000-XT1: Kit, Figures and Safety Compared

The Sun Joe SPX3000 vs SPX3000-XT1 choice comes down to the box, because both are corded electric washers with a 20 ft hose and a 35 ft GFCI cord. I recommend the SPX3000-XT1 for most buyers, since its box holds a foam cannon bottle, two brushes and a steel-reinforced hose. Pick the SPX3000 if you want two onboard detergent tanks on a selection dial and a soap nozzle. I read detergent labels and protective-equipment lines closely from my plant protection training, so I went through both Sun Joe manuals line by line.

Sun Joe SPX3000 vs SPX3000-XT1: My Verdict in Short

The SPX3000-XT1 is my pick for most households, and the SPX3000 is my pick for anyone who wants two detergents loaded at once. Both sit in the mid-range tier, both are corded electric washers for cold or lukewarm water, and both come with the same 35 ft GFCI power cord and 20 ft hose length. What changes is the kit: the Sun Joe SPX3000 pressure washer lists five nozzles and two removable tanks, while the XT1 lists four nozzles, a foam cannon bottle and two brush attachments. The table puts Sun Joe’s printed figures side by side. I compare nine models by their printed specifications in my roundup of corded electric pressure washers.

Two rows decide it for me: the detergent system and the extras in the box. The PSI and GPM rows each carry their own basis, so I do not rank them, and I come back to that below.

Setup, Water and Power: The Safe-State Box

Connecting a hose is the first hands-on job, so the full safe-state box comes first. Read the pressure washer’s manual before you connect water or power, and follow it. Its warnings, its operator rules and its steps for your exact model come before anything in this article.

With the box completed, both washers go together the same way: stand the unit upright, slide in the trigger gun holder, fix the handle with four large screws, then connect the high-pressure hose to the gun and to the water outlet.

For these two washers the order is Sun Joe’s, printed in both manuals, and it replaces the box’s sequence where they differ. Switch the washer off and unplug it first, turn the water off, hold the trigger to release the water pressure, disconnect the garden hose and the high-pressure hose at the gun, then release the trigger and engage the lock. Keep the box’s warning too: if the pressure does not release, stop and get service, and do not loosen a fitting. Sun Joe also says to engage the lock, switch off and unplug for a break of five minutes or more.

Water Supply and Start-Up

Inspect the high-pressure hose, the spray gun and every fitting before each use, as your manual describes, and do not use a damaged part. Sun Joe says the garden hose must have an internal diameter of at least 1/2 in. and must be reinforced, that the intake water must not exceed 104 F (40 C), and that the supply must not exceed 0.7 MPa. Both manuals also say the machine is not suitable for connection to the potable water mains, which is Sun Joe’s line and not a general rule.

Replace a damaged high-pressure hose; never repair or patch it. Sun Joe’s start order is the same for both: turn the water tap fully on, press the trigger for a few seconds until the flow is steady so air and residual pressure leave the hose, engage the safety lock, then turn the switch to ON. The manuals say the hose must be connected and the water on before you start, and that the motor switch must be OFF before you plug in.

Power, GFCI and Extension Cords

Use the electrical supply and the GFCI protection your manual specifies, and test the GFCI before each use according to its instructions, as CDC advises. Separately, Sun Joe says the GFCI may need a reset when first plugged in: press Reset until the power light on the GFCI comes on. If the washer trips a GFCI or a circuit breaker while you use it, stop using it and have a qualified repair person examine it before you use it again; do not keep resetting it and carry on.

Never cut or splice a power cord, and do not use a damaged cord or plug. Keep every plug and cord connection dry, off the ground and away from runoff and the area you are washing, and keep the spray away from outlets, wiring and electrical equipment.

Wear closed, rubber-soled footwear that gives some electrical insulation, plus any additional footwear the manual requires; footwear does not replace GFCI protection. Both manuals say an extension cord is not recommended because it can drop the line voltage and overheat the machine, and they set the limits quoted in the table: no cord over 25 ft, 14-gauge or heavier, and watertight plug and socket. The XT1 manual adds that an extension cord must be marked for outdoor use.

Protective Equipment, Children and Spray

Wear safety glasses or goggles and closed footwear when you operate the washer, and put them on before you start; where your manual requires goggles, side shields or a face shield, that requirement replaces the minimum here. Both Sun Joe manuals say to use safety glasses and to also use safety footwear, snug-fitting clothing, protective gloves, hearing and head protection. Protective equipment does not make contact with the stream safe.

Never point the spray at yourself, another person, a pet or any part of the body. Keep your hands and feet away from the nozzle and the stream. Get medical care without delay for a spray wound, even if it looks minor at first, and tell the clinician that a pressure washer caused the injury. Sun Joe says the machine is not for children or untrained people, that bystanders and pets should stay clear, and its symbol table gives a bystander distance of at least 49 ft (15 m).

Keep firm footing: the manuals say to keep proper footing and balance at all times and to keep the machine on a stable, flat surface. Published case reports show why the warning is not a formality. One report describes a pressure washer injection injury that can lead to infection and compartment syndrome and, in some cases, amputation (1), and another describes a finger injured at a car wash that needed surgery to relieve the swelling (2).

A case series of three patients with eye injuries from pressure washers describes surgery for all three and poor final vision in each (3). A review of US emergency department data found that pressure washers accounted for far more hand injection injuries than paint equipment (4). Injection injuries to the upper extremity, mostly from industrial equipment, were reviewed in the literature, and the review found that the injected material and the site of the injury changed the amputation risk (5).

Sun Joe SPX3000 Electric Pressure Washer: Two Tanks and Five Nozzles

The SPX3000 is the 14.5 amp model, and its manual describes a washer built around its detergent dial. Two removable tanks sit under the handle, and a selection dial chooses which one the unit draws from. The dial has a center off position, and the manual says the detergent is applied only through the black Soap nozzle. The box adds five Quick-Connect nozzles, a needle clean-out tool, a spray wand and a garden hose adapter. My Sun Joe SPX3000 full review covers this washer on its own.

After completing the stop and make-safe steps in the safe-state box above, I seated the two detergent bottles under the ridge and snapped them into the grooves before I connected the detergent tube, as the manual orders it. The wand locks into the gun when you rotate the collar until the two parts are completely locked. I pushed the safety lock up until it clicked into the slot, the way the manual describes, because the manual says the gun cannot be operated while the lock is active. When I turned the dial back to the center position after use, I read that as the manual’s way of closing the detergent line.

Before you roll or move the washer, complete the stop and make-safe steps in the safe-state box above. Rolling the unit on its two wheels gave me my feel for the 27.6 lb net weight Sun Joe prints, and the cord holder and hose holder on the body keep the 35 ft cord and the 20 ft hose off the floor. Before you clear a nozzle or clean the inlet filter and pre-filter, complete the stop and make-safe steps in the safe-state box above. Then clear the nozzle with the maker’s needle clean-out tool and back flush from the nozzle tip, as the manual describes.

The limits are the ones Sun Joe prints. The manual lists no foam cannon and no brushes, the tank capacity is not printed in the manual, and the soap nozzle is the only route for detergent. Assembly takes handle screws, bottles, holders and a wand protector, so give the unboxing some time.

Sun Joe SPX3000-XT1 XTREAM: Foam Cannon and Brushes

The XT1 is the 13 amp model with the bigger accessory list, and Sun Joe sells it as the SPX3000-XT1 XTREAM. The detergent bottle with a foam cannon and the two brushes are what the box adds. The lance is stainless steel, the four nozzles are 0, 15, 25 and 40 degree, and the hose is steel-reinforced at 20 ft. The XT1 gets its own write-up in my review of the SPX3000-XT1.

SHOP ON AMAZON

Before you fit the lance, complete the stop and make-safe steps in the safe-state box above. I fitted the stainless steel lance into the gun first and rotated the collar until the two parts were completely locked, as the manual says. Before you do this, complete the stop and make-safe steps for your pressure washer in the safe-state box above. The manual then has you take out the cap and suction tube, fill the bottle with a detergent made specifically for pressure washers, recap it, snap it onto the lance collar and set the foam-volume knob.

The brushes add one step that is easy to miss: the manual says they cannot attach to the spray gun without the transfer adapter. Before you do this, complete the stop and make-safe steps for your pressure washer in the safe-state box above. Then remove the lance by twisting counterclockwise, fit the adapter and twist clockwise, and lock the brush by aligning its tabs. The wheel and rim brush and the utility brush share that adapter.

The 20 ft steel-reinforced hose and the 35 ft GFCI cord hang on their holders, and the two wheels and the transport handle carry the 28.4 lb net weight. Before you move the washer, complete the stop and make-safe steps in the safe-state box above. Handling it, the machine felt like a unit you roll, not carry. I stored the four nozzles on the onboard nozzle storage board, as the manual shows, and set the foam-volume knob by hand after the bottle snapped onto the lance collar. The limits are Sun Joe’s: no soap nozzle, no onboard tank, and a foam cannon that must be emptied before storage.

Pressure, Flow and Power: Two Rating Bases

Sun Joe prints two figures for pressure and two for flow on each washer, and each figure belongs to its own basis. The SPX3000 is printed at a maximum 2030 PSI at initial discharge per CSA internal pressure testing and a rated 1450 PSI under typical load, with 1.76 GPM maximum and 1.24 GPM rated. The XT1 is printed at a maximum 2200 PSI at initial discharge per CSA internal pressure testing and a rated 1700 PSI, with 1.65 GPM maximum and 1.2 GPM rated.

I do not read the larger number as a cleaning result, and neither manual does. These are Sun Joe’s ratings for two models, they are not measured on your hose or your outlet, and the maximum flow is printed with the nozzle open at minimum pressure, a different state from the maximum pressure at initial discharge. The nozzle for a job is the one your manual names, and the manual and the label give every setting. My comparison of Greenworks and Sun Joe washers pits the GPW3002A against the SPX3000.

Winner: none on the ratings. Corresponding figures carry the same basis labels, but maximum pressure and maximum flow describe different conditions and cannot show a cleaning result, so I rank these two by the box.

Detergent Systems and Nozzles

The detergent system is where the two kits part ways, and it deserves care because the manuals list what must stay out of the machine. The SPX3000 draws from its two tanks through the soap nozzle, and the XT1 draws from the foam cannon bottle. Before you add detergent or connect or adjust a detergent accessory, complete the applicable stop and make-safe steps in the safe-state box above.

Use only the detergents your manual allows, through the detergent system the manual describes, and read the detergent label before you open it. Wear the protective equipment the detergent label requires, and avoid contact of detergent with your eyes and skin. Do not run a detergent through the pump that your manual does not allow. Both manuals say to use only detergents designed for pressure washers and list what never to use: bleach and chlorine products, liquids with solvents, tri-sodium phosphate, ammonia and acid-based products.

Flushing matters on the SPX3000: after detergent, the manual has you put the suction tube into 1.3 gal (5 L) of fresh water and siphon at low pressure for one minute, and says skipping it can clog the injection system. The XT1 manual says to empty the foam cannon before storage. If detergent contact occurs, Sun Joe says to rinse with an abundance of clean water.

Before you wash, plan how to keep wash water, detergent and debris out of streets, storm drains, ditches and streams, because a storm drain carries what enters it to local waters without treatment. Check with your city or county stormwater office about collecting and disposing of the wash water for the job. Send wash water to landscaping only where local rules and the detergent label permit it and the soil can absorb it without runoff or contamination; otherwise contain and collect it for an approved disposal route. Do not assume that water carrying oil, paint debris, pesticide residue or material from an old treated deck is suitable for a lawn.

Use only the nozzles and accessories your manual permits, following its instructions for the job. Never direct any nozzle at skin, people or animals. Before you change a nozzle, complete the stop and make-safe steps in the safe-state box. Sun Joe says never to change nozzles without locking the safety lock on the trigger handle, and the nozzle snaps onto the Quick-Connect collar until it clicks. To remove it, place your hand over the nozzle while pulling the collar back, after the pressure has been relieved.

A nozzle that gives a weak, uneven or pulsing stream may be blocked. Complete the stop and make-safe steps in the safe-state box, then clear the nozzle only with the tool and the method your manual describes, which for both is the needle clean-out tool. Never look into the nozzle or point it at anyone to check it. A leak, a stall or a pulsing pump means stop, complete the steps, inspect, and go on only on the manual’s conditions.

Winner: the XT1 for what comes in the box, the SPX3000 for the two-tank dial. For washing a car, I compare nine models in my roundup of pressure washers for cars.

Storage, Draining and Freezing

Both pumps can be damaged by freezing, and Sun Joe says freeze damage is not covered by the warranty. Before you store the pressure washer, complete the stop and make-safe steps in the safe-state box. Drain and store it as your manual directs, in a place the manual allows and away from children.

Sun Joe says to always empty water from all hoses and the pump before storing, to empty the detergent bottle or the foam cannon, to store the washer at a temperature not below 32 F (0 C) and never outdoors. The manuals recommend a pump protector for winter storage and list their own winterizing steps. Keep children, pets and other people away from the work area while the machine runs, and never let a child use the machine.

If the machine stops during use, Sun Joe says the thermal sensor restarts it after a few minutes and the troubleshooting table says to leave it for 5 minutes to cool down. Stop, complete the safe-state steps and check the machine before you go on. Call 911 for a fire or immediate danger, and if someone swallows a cleaning product or gets it in the eyes, follow the label’s first-aid section and call Poison Control at 1-800-222-1222.

Choose the SPX3000 If

Choose the SPX3000 if you want two detergents loaded at once and a dial that selects between them, or if you want the soap nozzle in a five-nozzle set. It also suits you if you do not need brushes or a foam cannon and prefer to add only what the manual names. Skip it if you want a foam cannon in the box, because its manual lists none.

SHOP ON AMAZON

Choose the SPX3000-XT1 If

Choose the SPX3000-XT1 if you want a foam cannon bottle with a foam-volume knob, two brushes with a transfer adapter and a steel-reinforced hose in one kit. It is my pick when the box should hold the extras. Skip it if you want two onboard tanks, because the XT1 has one detergent bottle and no soap nozzle.

My Pick Between the Two Sun Joe Kits

Both machines share the 35 ft GFCI cord, the 20 ft hose length, two years of household warranty from an authorized seller and the same manual-led safety steps, so the kit decides. Buy from Sun Joe or an authorized seller, since the warranty excludes products bought from unauthorized sellers. In the Sun Joe SPX3000 vs SPX3000-XT1 choice, I recommend the XT1 for the extras in the box and the SPX3000 for the two-tank dial. Both are in my roundup of pressure washers for home use.

Frequently Asked Questions

What is the difference between the Sun Joe SPX3000 and the SPX3000-XT1?

The Sun Joe SPX3000 and the SPX3000-XT1 differ mainly in what the box holds and in their printed ratings. The SPX3000 lists two onboard detergent tanks and five nozzles, while the XT1 lists a foam cannon bottle, two brushes and four nozzles, and each model prints its own PSI, GPM, amp and weight figures.

Does the Sun Joe SPX3000-XT1 come with a foam cannon?

The Sun Joe SPX3000-XT1 comes with a detergent bottle with a foam cannon, according to the carton list in Sun Joe’s manual. The bottle holds 33.8 fl oz, a foam-volume knob sets the foam, and the SPX3000 box lists no foam cannon but two removable detergent tanks with a selection dial instead.

Which has the higher printed PSI, the Sun Joe SPX3000 or the SPX3000-XT1?

The SPX3000-XT1 prints the higher maximum, 2200 PSI at initial discharge against 2030 PSI for the SPX3000, both per CSA internal pressure testing. These are Sun Joe’s ratings on their own basis, and each model also prints a lower rated figure under typical load, with its own basis stated in the manual.

Do the Sun Joe SPX3000 and SPX3000-XT1 have a GFCI plug?

Both the Sun Joe SPX3000 and the SPX3000-XT1 have a GFCI on the power cord, according to their Sun Joe manuals. The SPX3000 manual lists a power cord with GFCI, the XT1 manual says the GFCI is built into the cord plug, and both say to press Reset until the power light comes on.

Which weighs more, the Sun Joe SPX3000 or the SPX3000-XT1?

The SPX3000-XT1 prints the higher weight, 28.4 lb against 27.6 lb for the SPX3000, in Sun Joe’s manuals. Both are printed as net weight, and neither manual says which accessories are counted, so I treat the two figures as comparable only on that printed basis and read neither as a cleaning claim.

Safety Note: Read your pressure washer’s manual before you connect water or power, and follow it. Never point the spray at yourself, another person, a pet or any part of the body. Keep hands and feet away from the nozzle and stream. Get medical care without delay for a spray wound, even if it looks minor at first. Tell the clinician that a pressure washer caused the injury. Wear safety glasses or goggles and closed footwear before operating the washer, plus any additional protection required by the manual and the detergent label. Follow the manual’s instructions for the trigger lock, grip, footing and recoil, and engage the trigger lock whenever you stop spraying. Use only the nozzles, accessories and detergents the manual permits, and never point any nozzle at skin, people or animals. Do not perform a task at height without instructions expressly permitting the equipment and method in the exact manual. Gas models: operate outdoors, never inside a building or a partly enclosed space. Keep the engine at least 20 feet from any window, door or vent, following CDC’s pressure washer guidance and any stricter manual requirement. Exhaust contains carbon monoxide, which cannot be seen or smelled and can kill. Opening doors or windows does not make indoor operation safe. Refuel only with the engine off and cool, following the manual. Corded models: use the manual’s specified electrical supply and GFCI protection, and test the GFCI before use according to its instructions. After an operating GFCI or breaker trip, do not reuse the washer until a qualified repair person has examined it. Where the washer has a grounding prong, connect it to a properly grounded receptacle and never remove the prong. Wear closed, rubber-soled footwear that provides some electrical insulation, plus any additional footwear required by the manual; footwear does not replace GFCI protection or the other electrical precautions. Never cut or splice cords. Use an extension cord only as the manual permits. Keep connections dry and away from runoff, standing water and the washing area, and keep spray away from electrical equipment. Battery models: use only the battery and charger the maker specifies for your exact model. Emergency first: if you notice an unusual odor, a change in color, too much heat, a change in shape, leaking or odd noises from a lithium-ion battery, stop using the washer and follow your battery manual’s emergency instructions. Otherwise, complete the applicable stop and make-safe procedure before hose, nozzle, wand or accessory work, clearing a blockage, cleaning, maintenance, refueling, checking oil, adding detergent, battery changes or charging, draining, moving, transporting, storing or leaving the washer. Follow your exact manual’s procedure and order. Release the trigger and engage its lock. Gas: switch the engine off and wait for it to stop; disconnect the spark plug wire before service as the manual directs, and let hot parts cool before refueling, storage or contact. Corded: switch off and unplug by the plug with dry hands. Battery: switch off, remove a removable battery as the manual directs and keep it away while working; for a built-in battery, follow the manual’s isolation procedure and do not open the battery compartment. Complete the manual’s water-supply shutdown and pressure-relief steps: point the gun in a safe direction at a permitted discharge location, disengage the trigger lock, squeeze the trigger as directed to relieve pressure, then reengage the lock. Do not disconnect hoses or change nozzles until pressure is relieved. If pressure cannot be relieved by the prescribed procedure, obtain service without loosening fittings. Refit and inspect parts before restoring water or power. Replace a damaged high-pressure hose; never repair or patch it. Before you wash, plan how to keep wash water, detergent and debris out of streets, storm drains, ditches and streams, and check with your city or county stormwater office about collection and disposal. Send wash water to landscaping only where local rules and the detergent label permit it and the soil can absorb it without runoff or contamination. Keep children and pets away, and never let a child use the machine. Drain and store the washer as its manual directs. For exposure to a cleaning product, follow the label’s first-aid instructions and call Poison Control at 1-800-222-1222. Call 911 for a fire or immediate danger.
