Higher ratedRanked #2 in Best Pressure Washers Under $300

Karcher K1700

4.2

2 sourcesall derived$173.47as of Aug 1

The Karcher K1700 is the compact, car-friendly pick: a CETA-certified cube washer measured at 1700 PSI and 1.1 GPM, and the easiest unit here to carry and store. Its gentle, controllable pressure has made it a favorite for washing cars and motorcycles without risking paint or trim, and touches like a foot switch and removable soap tank add polish. It's light-duty by design, not a heavy-grime machine.

Strengths

— Compact, lightweight cube design is the easiest in the group to store and carry
— CETA-certified for verified performance, with measured 1700 PSI / 1.1 GPM
— Gentle on paint and trim, ideal for safe car and motorcycle washing

Watch-outs

— 1700 PSI is the lowest pressure here, not for heavy-duty jobs
— Lower flow makes large-area rinsing slower
— Compact build sacrifices the big-wheel mobility of full-size units

Ranked #4 in Best Pressure Washers Under $300

Sun Joe SPX3000

3.9

3 sources2 derived$169as of Aug 1

The Sun Joe SPX3000 is the value benchmark for electric pressure washers, pairing 2030 PSI rated output with two onboard detergent tanks for under $200. TechGearLab scored it 65 out of 100 and called it a good all-around machine for average household use, well matched to cars, patios, siding, and driveways. Its universal motor won't last like an induction design. For the price, it handles light-to-medium cleaning better than it has any right to.

Strengths

— Excellent value: 2030 PSI rated output and dual detergent tanks for well under $200
— Two onboard soap reservoirs with a selector dial let you switch chemicals on the fly
— Total Stop System cuts the pump when the trigger is released, saving energy and wear

Watch-outs

— Universal motor and wobble pump are less durable than brushless/induction designs
— Owners report leaks and pressure loss over time on some units
— Loud compared to induction-motor electrics

Sun Joe SPX3000

The value pick against the more durable Ryobi RY142300 and Westinghouse WPX3000e, and a step up in features from the compact Karcher K1700. It matches the Greenworks GPW1951 on price but adds a second detergent tank.
