The Westinghouse ePX3100 is a compact electric pressure washer for home cleaning, with four steering wheels, a 25 ft hose and an onboard soap tank. This Westinghouse ePX3100 review looks at its rated pressure and flow, setup, care, and how it compares with three alternatives.
It fits homeowners who want a low-profile washer that rolls around a patio or driveway and stores in a tight space. If you need higher rated pressure, compare the ePX3500; if you need to carry the machine between locations, look at the ePX3100v.
Westinghouse ePX3100 review: what do you get?
The ePX3100 combines a compact body with a four-wheel base designed to steer through 360 degrees. It stands 16.5 in tall and weighs 19 lb, so its format suits buyers with limited storage who prefer rolling a washer to carrying one.
Westinghouse ePX3100: Best for compact storage
- 1900 rated PSI
- 1.24 rated GPM
- 25 ft hose
- 20 oz onboard soap tank
A compact electric washer with four steering wheels, five quick-connect tips and an onboard soap tank. Its rated pressure and flow suit routine home cleaning.
Pros
- Compact 16.5 in height
- Four 360-degree steering wheels
- Five quick-connect tips
- Onboard 20 oz soap tank
Cons
- Rated pressure is lower than the ePX3500
- A 25 ft hose may limit reach
The kit includes a steel wand, a 25 ft easy-coil nylon braided hose, five quick-connect tips and a 20 oz soap tank. The tip set includes 0°, 15°, 25°, turbo and soap applicator options.
The range of accessories covers different cleaning tasks, but the machine's real fit depends on the surface, reach and pressure you need. A compact format makes it easier to store and steer, while the hose length and rated output set practical limits on where and how you work.
What do the Westinghouse ePX3100 pressure and flow numbers mean?
The ePX3100 has 1900 rated PSI and 1.24 rated GPM, with maximum figures of 2300 PSI and 1.76 GPM. The maximum flow figure applies at the lowest pressure, so don't treat maximum pressure and maximum flow as figures delivered together.
Rated pressure and flow are useful for comparing washers. For a plain explanation of how each affects cleaning, see pressure washer GPM vs PSI.
The included nozzles also matter. A narrow spray concentrates force in a small area, while a wider spray spreads it out, so the appropriate tip and working distance depend on the surface and soil.
Who should choose the ePX3100?
Choose the ePX3100 if you want a compact washer that rolls and steers instead of requiring you to carry it. Its short body is a practical match for patios, fences, patio furniture and occasional driveway cleanup where you can position the machine within hose reach.
The onboard soap tank is useful when the cleaning job calls for detergent, and the five tips provide several spray patterns. Follow the washer manual and detergent directions, and use a tip and distance suited to the material.
The rated output makes this a household electric option, not the choice for every large or demanding cleaning job. If your main task is a driveway, plan to clean in manageable sections; our driveway pressure-washing guide covers a careful approach.
Who should skip the ePX3100?
Skip the ePX3100 if you need more rated pressure than it offers, need to carry the washer frequently, or expect to work far from its power and water connections. The ePX3500 has higher rated pressure, the ePX3100v has a built-in carry handle, and the WPX2300e has a longer GFCI power cord.
A 25 ft hose can mean repositioning the washer during a larger job. Measure the work area and think about where the unit can sit before choosing a compact machine.
Also consider the surface before choosing any pressure washer. Delicate trim, paint and softer wood can be damaged by a narrow spray at close range, so use a cautious setup and check the care guidance for the material.
How should you choose among these Westinghouse models?
Choose by the work area, how you plan to move the washer, and whether you need higher rated pressure or a longer power cord. The ePX3500 is the pressure step-up, the ePX3100 is the compact middle choice, the ePX3100v is carry-friendly, and the WPX2300e has a taller frame and longer cord.
| Model | Rated pressure | Rated flow | Hose | Design details |
|---|---|---|---|---|
| Westinghouse ePX3500 | 2000 PSI | 1.2 GPM | 25 ft | Compact body, four steering wheels, onboard soap tank |
| Westinghouse ePX3100 | 1900 PSI | 1.24 GPM | 25 ft | Compact body, four steering wheels, onboard soap tank |
| Westinghouse ePX3100v | 1800 PSI | 1.2 GPM | 20 ft | Built-in carry handle, detachable foam cannon |
| Westinghouse WPX2300e | 1900 PSI | 1.2 GPM | 25 ft | Steel frame, 8 in wheels, 35 ft GFCI cord |
The ePX3500 adds 100 rated PSI over the ePX3100, while the ePX3100 has a slightly higher rated flow. For the differences between those compact models, read Westinghouse ePX3500 vs ePX3100.
How do you set up and use the ePX3100?
Set up the ePX3100 on stable ground near the work area, water source and electrical outlet, with enough hose and cord reach to move safely. Connect the water supply and hose as the manual directs, attach the wand and chosen quick-connect tip, and confirm connections before powering on.
Before squeezing the trigger, point the wand away from people, pets, windows and fragile objects. Start with a wider spray and a test area, keeping the nozzle farther from the surface than you think you need; move closer gradually only if the material tolerates it.
For detergent, use the soap applicator and onboard tank according to the machine manual and soap directions. Rinse the surface as appropriate, and don't leave detergent to dry unless its instructions allow that method.
If you're new to pressure washing, how to use a pressure washer explains spray control and basic cleaning habits. Work in steady, overlapping passes rather than holding the spray in one spot.
What common mistakes should you avoid?
The most common mistake is using a concentrated spray too close to a surface. A 0° tip can be particularly forceful, so choose a broader spray for uncertain materials and test a hidden area first.
Don't assume the maximum PSI and maximum GPM describe one operating setting. Compare the rated figures, and avoid choosing a washer by the highest number in its name or product title alone.
A second mistake is placing the washer where the hose or cord can't comfortably reach. Check the layout in advance, keep connections out of the work path and reposition the unit instead of pulling hard on the hose.
Finally, don't use detergent without checking that it suits the washer and surface. Correct soap, application and rinsing matter, especially around plants, painted finishes and vehicle surfaces.
How should you care for and store the ePX3100?
Care starts with following the manual for shutdown, pressure release and disconnection after use. Keep the hose, wand and tips organized, and store the washer in a dry, protected place according to its storage guidance.
Inspect connections, hose and cord before each session for visible damage or leaks. Clear nozzle blockages only by the method the manual recommends, and avoid forcing a tool into a tip.
The low profile can make storage easier, but plan a spot where the hose won't be sharply kinked and the wand won't be knocked loose. For cold-weather storage, use our guide to winterizing a pressure washer and follow the ePX3100 manual for the exact procedure.
How we scored the Westinghouse ePX3100
The 8.4 score reflects the ePX3100's fit for compact household cleaning. Its four steering wheels, short body, soap tank and five-tip set make it a flexible home option, while its rated output and 25 ft hose make it less suitable for jobs that call for greater reach or higher pressure.
We compared its stated features with three Westinghouse alternatives and the needs of likely buyers. The score reflects that comparison, with the ePX3500 rated higher for shoppers prioritizing rated pressure.
Is the Westinghouse ePX3100 worth considering?
The Westinghouse ePX3100 review decision is straightforward: pick the ePX3100 for compact storage and steering wheels, the ePX3500 for higher rated pressure, or the ePX3100v for a carry handle. Choose the WPX2300e if its taller steel-frame design and 35 ft GFCI cord better fit your work area.
