Buying Guide
Choosing the right electric pressure washer involves understanding a few key factors. The ePX3100 excels in several areas, but knowing what to look for ensures you get the best tool for your specific tasks.
Power and Pressure: PSI and GPM Explained
PSI (pounds per square inch) measures the pressure, while GPM (gallons per minute) measures the water flow. Together, they determine cleaning power. The Westinghouse ePX3100 delivers 2300 max PSI and 1.76 max GPM. This is ample for cleaning cars, patios, driveways, and home siding. For lighter tasks, a lower PSI model like the Greenworks 2000 PSI Pressure Washer may suffice, but the ePX3100 offers a solid balance for most homeowners.
Portability and Storage
Electric pressure washers are generally lighter than gas models, but the ePX3100 stands out. At just 19 pounds and 16.5 inches tall, it is incredibly easy to move and store. Its four quick-lock wheels with 360-degree steering make maneuvering around obstacles simple. The compact design fits neatly in a garage corner or shed, a major advantage over bulkier units.
Versatility and Accessories
A good pressure washer is only as versatile as its attachments. The ePX3100 includes a pro-style steel wand with five quick-connect nozzles: 0°, 15°, 25°, turbo, and a soap applicator. This covers a wide range of tasks. For large flat surfaces like driveways, adding a surface cleaner attachment, such as the Westinghouse Universal 16.5” Surface Cleaner, can cut cleaning time dramatically.

Build Quality and Durability
The ePX3100 features a steel wand and a sturdy frame. The pump automatically stops when the trigger is not engaged, which reduces wear and saves energy. Westinghouse backs this model with a 3-year limited service, labor, and parts coverage. For a gas-powered alternative with higher PSI, consider the Westinghouse WPX3200 Gas Pressure Washer, but for most home users, the ePX3100 offers reliable, long-lasting performance.
Final Thoughts
For most homeowners seeking a convenient, powerful, and easy-to-store cleaning solution, the Westinghouse ePX3100 Electric Pressure Washer is an excellent choice that balances performance with portability. If you need maximum power for heavy-duty jobs like stripping paint or cleaning large concrete areas over 500 square feet, the Westinghouse WPX3200 Gas Pressure Washer provides the extra PSI and flow rate to get the job done faster, though it requires more maintenance and storage space.
Frequently Asked Questions
Can the Westinghouse ePX3100 be used with a surface cleaner?
