Westinghouse ePX3100 vs Sun Joe SPX3000: Rated Specs
The useful comparison is rated pressure and flow, not two unrelated maximum claims. Westinghouse is a low-profile four-wheel unit with a 25-foot hose; Sun Joe is an upright two-tank design with a 20-foot hose.
Best for
Homeowners choosing a corded electric pressure washer for manufacturer-approved vehicle and exterior cleaning by rated output, reach, nozzle set and detergent workflow.
Probably not for
Commercial duty, paint or graffiti removal promises, drawing from an unapproved water source, or cleaning people, animals, live electrical equipment or fragile surfaces.

Westinghouse ePX3100 electric pressure washer
Westinghouse ePX3100 is a 13-amp, low-profile electric pressure washer rated at 1900 PSI and 1.24 GPM. It has a 25-foot hose, 35-foot power cord, four 360-degree wheels, a 20-ounce onboard detergent tank and five quick-connect tips including a turbo nozzle.
Pros
- The 25-foot hose provides five more feet of pressure-hose reach than SPX3000.
- Its four-wheel low-center design and 19-pound published weight favor movement around a work area.
Cons
- The nozzle set lacks the wider 40-degree fan tip included with Sun Joe.
- One detergent tank does not switch between two solutions as directly as SPX3000’s dual tanks.
Who it’s for: Choose it for compact four-wheel movement, the longer hose and a turbo tip. Pass if two detergent reservoirs and a 40-degree fan nozzle better match the planned work.

Sun Joe SPX3000 is a 14.5-amp upright electric pressure washer with certified ratings of 2030 PSI and 1.2 GPM. It includes a 20-foot high-pressure hose, 34-inch stainless spray wand, five quick-connect tips and two removable 0.9-liter detergent tanks.
Pros
- Two detergent tanks support separate compatible solutions without emptying one onboard reservoir.
- The included 40-degree tip offers a wider fan option than Westinghouse’s standard tip set.
Cons
- Its 20-foot high-pressure hose is shorter than Westinghouse’s 25-foot hose.
- The upright two-wheel form is a different movement pattern from ePX3100’s four swivel wheels.
Who it’s for: Choose it for the dual-tank detergent setup, 40-degree tip and slightly higher certified rated PSI. Pass if the longer hose and low-profile swivel base are more valuable.

Westinghouse publishes 2300 maximum PSI and 1.76 maximum GPM at its lowest-pressure condition, then gives rated figures of 1900 PSI and 1.24 GPM. Sun Joe publishes a certified rated 2030 PSI and 1.2 GPM for SPX3000; its current marketplace language may also show a higher maximum pressure. Pressure and flow peak under different operating conditions, so multiplying the two largest headline numbers does not describe one real cleaning point.
The fairest specification row uses the rated values: Sun Joe has the slightly higher rated PSI, while Westinghouse has the slightly higher rated GPM. Those small differences do not establish faster cleaning without the same nozzle, distance, water supply, surface and protocol. This site did not measure pressure, flow or cleaning time and does not claim that either unit removes a certain percentage more material.
Nozzle selection controls risk as well as coverage
Both include 0, 15, 25-degree and soap tips. Westinghouse adds a turbo nozzle, while Sun Joe adds a wider 40-degree fan tip. A narrow or rotating stream concentrates force and can etch wood, scar paint, damage mortar, drive water behind siding or cut skin. Begin with the widest manufacturer-approved fan, stand back and test an inconspicuous area before moving closer.
Match the manual to the surface rather than relying on a generic cleaning chart. Vehicle finishes, aging decks, composite boards, screens and painted surfaces vary. Never point the wand at a person or animal, and do not use a pressure washer from a ladder where reaction force can upset balance. Wear eye and foot protection and keep bystanders outside the spray and debris zone.
Hose, cord and chassis determine the working radius
ePX3100 provides a 25-foot high-pressure hose and 35-foot power cord on a 19-pound, 16.5-inch-tall chassis with four swivel wheels. SPX3000 provides a 20-foot hose in a taller upright two-wheel format. The extra five feet of pressure hose can reduce how often the Westinghouse body is moved, while Sun Joe’s upright handle gives a familiar cart arrangement.
Use only extension cords explicitly permitted by the manufacturer and sized for the current and distance. Keep electrical connections dry and off the ground, use a properly grounded GFCI-protected outlet, inspect the cord before each use and never pull the machine by its cable. Water-supply hose diameter, flow and inlet condition also matter. Purge trapped air and connect water before running the pump as the manual directs.
One detergent tank or two is a workflow choice
Westinghouse supplies one 20-ounce onboard tank. Sun Joe supplies two removable 0.9-liter tanks with a selector, which can be convenient when alternating between two approved detergents. The second tank adds cleanup and is only useful if two solutions are genuinely needed. Neither system should be filled with bleach, solvent or a chemical the manual does not approve.
Detergent normally applies through the designated low-pressure soap tip rather than every high-pressure nozzle. Follow dilution and dwell-time instructions for both the machine and chemical, prevent runoff from reaching storm drains where prohibited and rinse the system as directed. More detergent does not make a fragile surface safer to pressure wash. The cleaning product, surface coating and local disposal rules all need separate checks.
Choose around reach, tips and storage
Choose ePX3100 for its 25-foot hose, four-wheel low-profile chassis, single tank and included turbo tip. Choose SPX3000 for dual detergent tanks, a 40-degree tip and its certified 2030 PSI rated figure. Measure the storage position, identify the outlet and water source, and map the farthest point before buying. The more useful machine is the one that reaches the task without unsafe cord or hose improvisation.
