Westinghouse ePX3100v Electric Pressure Washer, 2100 Max PSI 1.76 Max GPM, Detachable Foam Cannon, 3-Nozzle Set Review (2026)

Who this pressure washer fits

This washer is aimed at car owners who want a two-bucket wash routine that starts with a proper foam pre-wash rather than dragging a mitt straight into dirt and grit. The included detachable foam cannon is the headline feature here, letting you coat the car in thick snow foam to loosen contamination before contact washing, which is the technique most detailers recommend to reduce swirl marks. At 2100 max PSI, it also has enough power for rinsing wheels, sills, and light patio or fence cleaning without needing a heavier duty unit. Owners who mainly need raw pressure for driveways or siding, or who want more nozzle variety built into the wand, may be better served by a higher pressure Westinghouse model or a unit with a 5-nozzle set instead.

Specs and design explained

The ePX3100v delivers up to 2100 max PSI and 1.76 max GPM at its lowest pressure setting, with 1800 rated PSI and 1.2 rated GPM during normal operation, figures that put it in the mid-range for consumer electric washers. It weighs about 17.6 pounds and includes a built-in carry handle, so moving it around a driveway or garage does not require a cart. Water reaches the nozzle through a 20 foot easy-coil hose, and power comes from a 35 foot GFCI-protected cord paired with a 13-amp universal motor and axial cam pump. A Total Stop System automatically shuts the pump off when the trigger is released, which both saves energy and reduces wear on the pump over repeated short bursts of use.

Setup, foam washing, and storage

Getting started means connecting a garden hose, attaching the pro-style gun with one of the three quick-connect spray tips, and clipping on the detachable foam cannon when you want a pre-wash coat of suds. Because the cannon detaches rather than being permanently mounted, it needs its own spot in a bucket or shelf between washes, which is a small extra step compared with washers that build soap application into the wand itself. The 20 foot hose and 35 foot cord combine to give reasonable reach around most driveways without an extension cord, though larger vehicles or multi-car washes may still mean repositioning the unit partway through. The Total Stop System is worth knowing about, since the motor pausing between trigger pulls is normal behavior rather than a fault.

How it compares with other pressure washers

Against the Sun Joe SPX3001, which edges it out in this comparison with dual soap tanks built into the unit, the ePX3100v's detachable cannon is arguably a better foam-washing tool even if it means one more part to manage. Its sibling model, the Westinghouse ePX3100, steps up to 2300 max PSI and a 5-nozzle set with an onboard soap tank instead of a cannon, which suits owners who want more spray pattern choice and less to detach and store. Compared with the Sun Joe SPX2680-MAX, which pairs a lower 1600 PSI with its own foam cannon and extension wand, this Westinghouse offers more raw pressure at a similar foam-washing purpose. The three included nozzles cover the basics but fall short of the five-nozzle spread on some competing and sibling models.

Verdict and who should look elsewhere

For anyone building a proper snow-foam car care routine, the detachable cannon and balanced 2100 PSI output make this a sensible pick, and it earns our score of 8.2 out of 10 as a well-rounded unit rather than a specialist tool. Buyers who want more spray pattern flexibility without swapping in an extra nozzle, or who would rather not manage a separate cannon between uses, should look at the higher-nozzle Westinghouse ePX3100 or a Sun Joe model with a built-in soap tank. For a lightweight, portable washer focused on foam pre-washing before hand contact, though, this unit covers the job well.
