Independent pressure washer bench · 100 machines

The pressure washer that actually finishes your driveway.

Four questions, one tested recommendation

No email, no fake urgency. The quiz filters the bench by the surface you clean, power source, how often you carry it, and the tiebreak that matters to you.

1Answer four questions about the job, not the marketing copy.
2We score all 100 machines against your answers using measured PSI, GPM, reach and weight.
3You get one match plus three alternates — every one a machine we actually tested.

How we bench

The routine every machine runs

No sponsored placements, no manufacturer figures taken on faith.

01 / Measured output

Pressure and flow at the nozzle

We log working PSI and GPM rather than peak marketing claims, then multiply them into cleaning units — the number that actually predicts how fast grime leaves concrete.

02 / Surfaces

Concrete, siding, deck, vehicle

Four passes per machine — same detergent, same distance, same operator, same order.

03 / Handling

Weight, wheels, hose kink

Scored on carrying it up three steps and coiling the hose cold.
