Honda GX Engine Performance

As part of their Powershot line, this Simpson pressure washer is capable of delivering up to 4200 PSI and 4.0 gallons per minute of water. Simpson takes advantage of Honda’s HX390 engine. It bumps the price up, but the reliability of Honda’s GX engines borders on legendary.

Small Frame, Big Performance

The performance specifications put this model right on the edge of having to move up to a large frame and that’s where it has one of its biggest advantages. By being able to call on 4200 PSI without going to a large footprint, you keep a more convenient level of portability into more jobs than your 3000 PSI unit.

The frame is made from welded steel, so you can expect it to last a long time. Simpson is confident enough to warranty the frame for 10 years. If you’re taking notes, they also give you 5 years on the triplex pump and 3 years on the engine.

Price and Placement

The Simpson PS4240 is not in the same class as the $300 units you might pick up in a pinch at your local big box store. Retail prices are running in the $1100 range, though I have seen some prices dip below $1000 from a handful of retailers. That puts it squarely in the Pro market, leaving us with the question of how well it performs.

For that, I’ll turn it over to our team at OPE Reviews where they’ve had the chance to put the PowerShot PS4240 through its paces and give it a 4.4-star rating.
