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.
Consider purchasing a light-duty consumer, heavy-duty consumer or professional model pressure washer for your personal needs.
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 understands 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.
Horsepower (HP)
A higher horsepower engine is needed for higher PSI and higher GPM. The combination of PSI and GPM is what does the cleaning.
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.
| Application | 1500 PSI | 2600 PSI | 3000 PSI | 4000 PSI |
|---|---|---|---|---|
| Charcoal Grill | x | x | x | x |
| Bicycle | x | x | x | x |
| Automobile | x | x | x | x |

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.

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 pressure washers. They use less soap to sanitize and degrease, making them ideal for industrial and farm use. Cold water pressure washers are less complicated and are more compact for easy portability.
Product Support
Toll-free number. Talk directly to skilled NorthStar™ personnel at the factory where the product is made.
Quick Response Time
All NorthStar™ replacement parts orders ship within 24 hours. In fact, 80% ship the same day.
Lower Maintenance Costs
NorthStar™ replacement parts cost 33% less than the competition.
Quality
NorthStar™ meets the high-quality standards expected by Northern Tool + Equipment Co.
Proven Performance
You can rest assured your product will last. That's because all NorthStar™ designs go through rigorous engineering life tests before going to market.
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.
Goodyear & Unisource Non-Marking Hoses
All NorthStar™ pressure washers are equipped with a yellow, non-marking hose. These hoses will not leave black marks the way standard black hose can on concrete or other surfaces that have just been cleaned. Pressure washers rated up to 3000psi are equipped with a Goodyear™ brand hose and pressure washers with a 3500psi and 4000psi rating come with a Unisource™ brand hose.
Ceramic vs. 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.

When do I change the oil and what type of oil do I use?
I'm not getting any pressure. What do I need to check?
My engine will not start. What do I do?
I cannot get any soap injection. What should I do?
If the above steps are followed to no avail, remove the high-pressure hose and run the pump/engine with the soap injector turned on to see if it works without the hose. If it does, replace the hose, gun, wand, nozzle and tip, in that order, to determine which item is defective.
It is starting to get cold. How do I winterize my pressure washer?
Prepare the pressure washer for storage by running a 50/50 mix of water and anti-freeze into the unit. This will keep the internal parts lubricated, protected from rust, and prevents the pump from freezing. Please use environmentally friendly anti-freeze whenever possible using the following procedure:
Note: This procedure works best if you have someone to help with the hose and funnel.
