Best Pressure Washer for a Small Concrete Patio: Three 2,300 PSI Electrics That Finish in an Hour

What a small patio asks of a washer

A 200 to 300 square foot concrete patio needs 2,000 PSI or so with a fan nozzle to lift a season of dirt and mildew, and it needs a machine that stores in a corner and does not tip when the hose is pulled around the furniture. That rules out gas and the biggest electrics and points at the 2,300 PSI class, where the three machines here sit. They differ in how much water they move, how they are built and how stable they are, and any of them with a 12-inch surface cleaner attachment turns an hour into twenty minutes.

This guide is built from the published specifications and manuals of each washer and from recurring owner feedback. We have not run these washers ourselves.

How the three compare

Westinghouse ePX3100: the one that stays upright

Small patios have chairs and planters, and a tall washer pulled around them by its hose falls over. The ePX3100 is 16.5 inches tall and 19 pounds with four quick-lock wheels that steer 360 degrees and a low center of gravity, which is why owners mention it never tipping. It is rated 1,900 PSI and 1.24 GPM with a 2,300 peak, has a 25-foot braided hose and a 20-ounce soap tank, and the pump stops when the trigger is released.

Greenworks 2300: the fast rinse

The Greenworks 2300 claims up to 2.3 GPM, and while the maximum flow comes at reduced pressure, more water through a 25-degree nozzle rinses a patio noticeably faster. A brushless motor drives an axial cam pump and a pressure-sensing system matches output to the nozzle fitted. It is larger than the Westinghouse and costs more, and it finishes first.

Westinghouse WPX2300e: built to last

The WPX2300e has the induction motor that the cheaper electrics lack, which runs cooler and lasts years longer, driving a three-piston axial pump rated 1,900 PSI and 1.2 GPM. The steel frame on 8-inch never-flat wheels rolls over a step, the 35-foot GFCI cord and 25-foot hose reach the far corner, and five nozzles including a turbo come in the box. For a household that will wash a patio, a car and a fence every year for a decade, it is the one to buy.

Washing a patio well

Move the furniture, sweep and wet the surface. Apply a concrete cleaner or degreaser to mildew and oil and let it dwell. Wash with the 25-degree nozzle in overlapping strokes at a steady distance, or fit a surface cleaner and walk it like a mower. Rinse toward the drain. Use the turbo nozzle only on stubborn stains, and never the 0-degree nozzle on old concrete, which etches.

Which one should you buy

Buy the Westinghouse ePX3100 for a compact machine that will not tip on a small patio. Buy the Greenworks 2300 for the fastest rinse. Buy the Westinghouse WPX2300e for an induction motor and steel frame that last.
