Karcher Pressure Washer Buyers Guide

Now that you have an idea of the best Karcher pressure washers, it’s time to narrow down your choices. Our buyer’s guide gives you everything you need to know for selecting the right Karcher pressure washer to meet your needs.

Why Do You Need a Pressure Washer?

Start the selection process by identifying the tasks you do around the home that benefit from the assistance of a pressure washer. For instance, if you wash your car on the weekends, but don’t have any other needs for a pressure washer, then go with the specialized K2 model designed for this purpose.

However, if you think you could use a washer to clean out your gutters, spray down your walls, or degrease your driveway, you’re going to need a powerful, multi-functional machine. If you’re a homeowner, you could benefit from one of these multi-use models as well, but if you rent your place, you might not have to do that type of maintenance to your home.

Write down a list of chores you do around the house that can benefit from the use of a pressure washer, and then cross-reference the tasks to the choices on this list to find the model that’s right for you.

Pressure Washer Accessories

Pressure washers are versatile tools offering you plenty of user functionality for a variety of tasks. Whether you’re a contractor, landscaper, or homeowner, there’s a pressure washing system from Karcher to suit your needs.

One of the reasons why pressure washers offer so much multi-functional use is due to the full range of accessories that alter the performance of the machine under different working conditions. Here is a quick look at the top accessories available with Karcher pressure washing kits.

Surface Cleaners

This accessory helps you clean flat surfaces fast. The tip fits onto your pressure washer wand, providing consistent coverage and removal of dirt and debris from flat surfaces.

The nozzle features an internal rotating bar that distributes the pressure evenly, and the round enclosure holds back any overspray from damaging surrounding objects like flowerbeds.

Brushes

The brush attachment for Karcher pressure washers operates on the same principle as the surface cleaner. The brush helps to drive away dirt and debris while the water cleans the surface.

Brushes are an essential accessory for cleaning cars and boats, as well as patio furniture and trash bins. Choose a model with a rotating brush for the best performance.

Wand Washer Tips

A rotary turbo washing nozzle rotates the water stream at 0-degrees and 3,000-rpm, providing a pulsing action through the wand that washes away the toughest grit and grime.

The stream rotates so quickly as it exits the nozzle, that it appears as a standard cone stream to the user during operation.

This accessory helps to remove hardened grease, grime, and oil marks from driveways, garage floors, and walls.

Wands and Lances

When selecting your machine, look at the wand. The “Vario” power-spray wand and the “Dirtblaster” wand both offer individual functionality, and some models come with both types attached.

Look for a telescopic model if you need to clean gutters, as this feature helps you reach further during your cleaning.

Perfect for cleaning decking

Brooms

The broom accessory is a combination of a rotating power brush and a surface cleaner in one tool. It’s a powerful accessory for cleaning cars, boats, and tougher areas like floors and driveways. The broom operates by connecting to the pressure washer wand.

The wand then connects to two or three ports in the broom, broadening the coverage area for easy work cleaning larger flat surfaces, like shop floors. Some models come with rollers on the broom for smooth movement.

Contractors will benefit the most from using this accessory, and there aren’t many uses for it around the home.

Foamer Wands and Tips

Most Karcher models come with onboard detergent tanks. If you’re washing down your car, boat, or a wall, and you want to create a rich foam that eats away debris and dirt from the surface you’re cleaning, use a foamer.

The foamer attaches to the tip of your power-wand, mixing the detergent with the water stream. The Karcher K2 car cleaning kit includes a foamer that provides your car with a deep clean, keeping it in showroom condition.

The Difference Between Gas-Powered and Electric Pressure Washers

If you look at the top three models of Karcher pressure washers in this review, you’ll notice there are two electric models and one gas-powered model. So, which one suits your needs? If you need a pressure washer for use around the home, then an electric model is fine. The unit comes with a power cord that long enough to reach any electrical outlet. You also have the option of connecting it to an extension cord to improve the range of the machine.

An electric model produces a powerful enough water stream to handle most jobs around the home, from cleaning your driveway to washing your car. However, if you’re a contractor or a landscaper, you need a more robust, portable machine.

A gas-powered Karcher pressure washer is the ideal choice for contractors that need more power and portability from their pressure washer system. Gas-powered models have no electrical cord limiting your range, and they produce higher operating pressures for tougher jobs.

Karcher Pressure Washer FAQ

In case you’re still sitting on the fence with your purchase decision, check out this list of frequently asked questions.

What does psi mean when referring to a pressure washer?

PSI is a term that refers to the Pounds Per Square Inch produced by the water jet, leaving the nozzle of the spray wand. The higher the psi rating on the machine, the more suitable it is for tough cleaning jobs.

If you’re cleaning your car, you only need low psi ratings in your machine. However, if you need a pressure washer for degreasing driveways of shop floors, or cleaning walls, then choose a pressure washer with a high psi rating.

What tips suit which jobs with a pressure washer?

When using your pressure washer, the type of tip you use alters the water jet produced by the wand. Follow this as a quick-reference guide for selecting the right tip for your application.

  • 0° – For the toughest cleaning jobs
  • 15° – For stripping paint and grease from surfaces
  • 25° – For flushing dirt from sidewalks and gutters
  • 40° – For cleaning large areas and vehicles

Will a pressure washer damage my car?

There are specific nozzles that mitigate the pressure produced by the water stream. If you wash your car with the wrong nozzle attached to the pressure washer, it could damage your paint or dent your bodywork. Always work with the vehicle cleaning nozzle when cleaning your car or boat.

Why do the spray nozzles clog?

Nozzles will clog when debris enters the system. You need to ensure you remove all clogs immediately to prevent over-pressurizing the machine, causing it to fail.

Can I leave the washer on when not in use?

Never leave your pressure washer running while not in use. When you don’t pull the trigger, and the motor is running on the pump, then the water cycles through the pump, causing it to heat up. The hot water causes the melting of internal components and the eventual failure of the pressure washer.

Can I run hot water through the pressure washer?

No, running hot water through the machine will damage the internal components. There are hot-water pressure washers available, but there are none of these machines in the Karcher range above.

Conclusion

Karcher makes the best premium-brand pressure washing equipment, hands down. There’s a model on this list to suit any need for a pressure washer around the home. If you’re still battling to narrow down your selection, you can rely on our top choices for guidance.

Our top choices include models for professional and home use, as well as the best budget buy. One of these models is sure to find a place in your tool shed or on your contracting crew.
