What should I consider before purchasing a pressure washer?

Personal Use:
Pressure washers for home use offer the benefit of cleaning better with less effort and in less time. The right combination of PSI (pounds per square inch), GPM (gallons per minute), nozzles, attachments and cleaning solutions let you wash siding and windows, clean walkways, driveways and patios, bring wood decks and fences back to life, power clean vehicles, boats, lawnmowers, ATVs, even cut back vegetation growing alongside driveways and walkways.

Business Use
Pressure washers intended for business use will have greater pressure (PSI), water flow (GPM) and horse power (HP). Plus, you get extra features designed for greater performance necessary for heavy-duty cleaning in a shop, at a construction site or on a road crew. Depending on the model, these features could include a longer-lasting pump with adjustable pressure, easy-start engine, larger tank, wheel cart with large tires, hot water capability, longer hose and industrial-grade gun and wand. Northern understand the needs of the business user, and offers a great selection of professional and industrial pressure washers, in gas-powered or electric, cold or hot water models.

Pounds Per Square Inch (PSI)
A pressure washer's PSI rating is the maximum amount of force (pressure) discharged by the pressure washer. The higher the PSI, the more cleaning power available and the more things you will be able to clean. See chart below.

Gallons Per Minute (GPM)
A pressure washer's GPM rating refers to the water flow during one minute of operation. The higher the GPM, the faster you will be able to clean. See chart below.

More GPM for Faster Cleaning*

Gas-Powered vs. Electric
Gas-powered pressure washers offer the portability necessary for outdoor work while providing higher pressures and flows for more industrial applications. However, gas pressure washers can only be used outdoors because the engines generate carbon monoxide.

Electric pressure washers must have safety features necessary when working near water, such as double insulation and a ground-fault circuit interrupter (GFCI). Though limited in overall power, electric pressure washers can be used indoors or outdoors and are quieter than gas-powered washers.

Hot or Cold Water Cleaning
Hot water pressure washers clean faster and more thoroughly than cold water washers. They use less soap to sanitize and degrease, making them ideal for industrial and farm use. Cold water pressure are less complicated and are more compact for easy portabilit

Ceramic vrs Non-Ceramic Plungers
The plunger is the moving part of a pressure washer pump that travels back and forth between rubber seals to create the flow and pressure of a pressure washing system. The material that is used on all industrial grade pumps is ceramic. This material has excellent properties that allow it to be extremely smooth — extending the life of the seals. Ceramic also does not wear. Non-ceramic plungers will wear and reduce the life of the seals. They are found only on pumps designed for short life.

NEUHAUS Key Pressure Washer Features
Safety Relief Valve
The safety relief valve is the designed weak point in the pressure washer. If the unloader malfunctions, the safety relief valve will open and relieve system pressure safely.

Quick-Couple Chemical Injector
One of the most common failures in a pressure washer system is the chemical injector. There is a small orifice in the injector that can become blocked with dried up soap rendering the chemical injector inoperable. The advantage of the quick-couple injector over the hard-plumbed style is that you can remove the quick-couple injector in seconds with no tools. When it becomes blocked up, simply throw it in a bucket of water overnight and the chemical will dissolve.

The second advantage of a quick-couple chemical injector is the option of removing the chemical injector and boosting pressure by 5 to 10 percent. This is accomplished by removing the small orifice that the chemical injector works with.
