Professional Pressure Washer Dewalt, NorthStar, Simpson

Professional pressure washer models are amongst high end pressure washer units available on the market today. Almost every manufacturer of pressure washers for the North American market has a professional commercial pressure washer. Professional washers are high pressure washers which are designed to do heavy duty jobs. These are not by any means portable washers but are cart mounted.

They are also favorite high pressure equipment for pressure washer rental businesses. They range in pressure washer psi from roughly 3000psi to 4000psi and can even be as high as 5000 psi. Professional pressure washer units which are often gas powered are good at doing bigger and heavier jobs within much less time compared to light duty 1500 psi type washers.

We have found pressure washers for professional use to have certain things in common as summarized below;

• priced on the higher end often $1000+
• high pressure output between 3000 psi and 5000 psi
• gas powered in most cases
• cold water washer in most cases even though there are many that are hot water pressure washers
• long hose at least 50 foot long
• the best ones have a Honda and CAT combo in engine and pump brands respectively
• they have triplex plunger pumps which can be rebuilt. These types of pumps have a longer life span

The Simpson Professional Pressure Washer 4200 PSI

Simpson pressure washers enjoy very good consumer ratings and reviews. They are amongst top pressure washers for professional service just as the two i.e Dewalt and Northstar we have showcased above. Their machines are rugged and designed to do the toughest of jobs on the industrial or commercial site.

It doesn't look that much appealing in design compared to Northstar for example, but will surely do the job to your satisfaction. It sells for about $1000.00 a general price range of the other two.

At 4200 psi this gas powered cold water washer can strip paint and clean fences, brick walls, sidings, driveways, remove crusty mud on equipment and trucks as well as remove tough grease from industrial machinery.

Running on a Honda GX390 commercial series engine and a General pump industrial triples plunger pump this is a good combination. Our best combination is Honda and CAT engine and pump respectively, however this Simpson will also do well with a General pump.

In terms of PROS expect a quieter operation and quick and easy start engine. There have been reports of users of Honda engines on professional washers such as this one always getting to run it on first pull even after a long period of non-activity in storage. This is the beauty of Honda engines.
