How To Increase The Cleaning Capacity And Performance Of Your Karcher Pressure Washer?

Why Choose Karcher?

The question you should be asking is, why not? Karcher has been in the industry since 1950. Since then, they have been developing Karcher pressure washer parts, accessories, cleaning machines, and agents that combine functionality, user-friendliness, and sophistication. Thanks to their in-house research facility, Karcher has over 1,300 patents and utility models. The company has also received awards from renowned institutions.

Karcher spells the difference, especially in home cleaning and car washing. They owe it to their certified manufacturing plants in the US, Mexico, Brazil, Germany, Italy, and China. They have the following ISO certifications:

  • ISO 14001 Environmental Management Standard
  • ISO 9001 Quality Management Standard
  • ISO 50001 Energy Management Standard

How Do Karcher Fare With Other Popular Brands?

Perhaps, in your opinion, certifications are not the best criteria to judge a manufacturer. True enough, comparing brands is a smarter way towards the best purchase. The buyer will, of course, be the ultimate judge.

So, are Karcher pressure washers any good? Let these comparisons speak for themselves.

1. Karcher Vs. Ryobi

Ryobi is a Japanese company founded in 1943. They are a manufacturer of components for automobiles, telecommunications, and electronics industries. When it comes to pressure washers, their units are known to be lightweight and compact but with different motor sizes to suit any application.

Is Karcher better than Ryobi?

In terms of cleaning systems, we think Karcher offers better quality. Karcher’s research and development facility focus on cleaning solutions, so you can expect to find interesting and innovative features on their pressure washer units. Besides that, Karcher offers a number of units that are suitable for very specific groups. For instance, the K7 Premium Home Pressure Washer has a single multi-jet lance, which you can adjust and replaced to suit the type of cleaning you want to complete indoors.

2. Karcher Vs. Stanley

Been around for over 170 years, Stanley has been known for its quality and innovative household tools. Stanley Black & Decker offers two types of pressure washer— gas-powered and electric— which have different manufacturers. Stanley pressure washer's cleaning power is taken from their powerful tri-axial pump and universal motor. The brand is also known to incorporate robust mobile design in most of their pressure washer units.

So, are Karcher power washers better than Stanley’s?

We’d say they come in on a tie on the range of pressure washers and value for the buck. However, in terms of customer support, Karcher pressure washer customer service has the edge because they are the manufacturers of their products.

3. Karcher Vs. Sun Joe

Sun Joe and its sister company, Snow Joe are known for their outdoor tools. From 2012-2016, Sun Joe had consistently ranked in the top charts for garden tools.

In terms of electric pressure washers, Sun Joe is particularly known for its SPX3000 model and the cordless SPX6000C-XR which both earned awards.

Should you choose Sun Joe over Karcher?

Yes, if you are more concerned with the starting cost, but if quality and durability is your primary criterion, Karcher will satisfy that. Sun Joe’s products are lower in prices. Karcher, however, offers a wider range of machines that are suitable for various jobs. In the long run, Karcher pressure washers will cost less.

4. Karcher Vs. Greenworks

The Greenworks Tools brand was founded to market lithium-ion technology and outdoor power equipment. Now, they are known for outdoor tools that have quite as much power than gas types but without the noise and fumes. Because their promise has been to deliver powerful machines without noxious fumes, they only manufacture electric and battery-powered types.

Is Karcher better than Greenworks?

Yes, we think so because Karcher offers a wider range of choices for pressure washers. Greenworks line of pressure washers are cheaper, but they are also in the lower end of the PSI range as compared to the Karcher line. Both, however, have regard for the environment.

5. Karcher Vs. AR Blue Clean

AR, which stands for Annovi Reverberi, an Italian pump maker, has been around for 60 years to produce its brand of pressure washers, AR Blue Clean. The company spends its resources on research to meet the cleaning needs of homeowners and industries. They do not only manufacture machines; they also develop a range of accessories.

Do Karcher Pressure Washers have better quality than AR Blue Clean’s?

We think they are on a tie. Like Karcher, AR Blue Clean manufactures their machines in-house. A research facility at AR, like at Karcher’s, is dedicated to developing cleaning systems. In terms of the variety of products, Karcher and AR Blue Clean both manufacture a wide range for different groups.

Important Features To Look For:

When shopping for the best Karcher Pressure Washer, it is important to consider the following factors at the least:

  • Pressure

The rule of thumb: the higher the pressure, the more power is focused on the grime. Thus, cleaning is more efficient. The pressure output, which is measured by pounds per square inch (PSI) and gallons per minute (GPM), determines which jobs can the pressure washer handle. The higher the PSIxGPM value, the better and faster the machine can clean. For Karcher, and perhaps in other brands too, washers that have higher PSIxGPM values are often pricier.

Fortunately, there is a wide range of cleaning machines at Karcher for specific needs. They are classified into light-duty, medium-duty, and heavy-duty. They have products such as the Karcher K2 Car and Home Kit with a maximum pressure of 1,600 and flow rate of 1.25 GPM. This is an example of a light-duty washer that is perfect for washing cars, as well as house premises, facades, and swimming pools.

  • Model

The model may not be as important as the pressure output, but it tells what kind of build the machine is capable of handling. Karcher has premium and compact models. There is no difference between these models in terms of specifications such as pressure and flow rate. They differ in the machine’s housing. For premium models, there is a board storage for Karcher pressure washer attachments and a hose reel. With such a structure, these models are bulkier and heavier and more robust. So, if the cleaning jobs you usually perform require a lighter build, the compact models would be more suitable.

  • Hose

Hose length is also an imperative feature to check in relation to the kinds of cleaning jobs. For washing cars, it is important that the length of the hose allows flexibility and movement without dragging the machine here and there. If the machine is bulky and heavy, a lengthy hose will ease the burden of rolling the machine to and fro while cleaning.

  • Accessories

Karcher also offers accessories such as a pipe cleaning hose, foam cannon nozzle, and extension wand among other tools that can increase the flexibility and efficiency of the pressure washer. Find out which Karcher pressure washer attachments are most suitable for the cleaning job at hand.

For example, if you have to clean the driveway, take the Deck and Driveway Cleaner accessory. Make sure it is compatible with the machine that you have. A general note from Karcher said devices from the Home & Garden range are not compatible with machines from the Professional range.

The Karcher Pressure Washer Parts To Buy!

Make the most of your Karcher Pressure Washer by getting the best accessories that will fit your cleaning needs. Here are some of them:

Using a surface cleaner can help complete your task faster since the wide coverage of this attachment allows you to cover more space.

Using Karcher pressure washer parts can help complete your task faster.

  • Rotating Wash Brush

This accessory is perfect for cleaning smooth and delicate surfaces such as your car or windows. With the rotating wash brush, the surface is scrubbed as the pressurized water pushes off the dirt and stains, leaving it smooth and clean.

  • Extension Wand

Need to clean high areas? That’s not a problem with the Karcher extension wand. It is a telescoping rod that allows you to clean gutters and other hard-to-reach areas. No more ladders for you. With the extension wand, cleaning is quicker, safer, and hassle-free.

  • Karcher Power Scrubber

Just the sound of it delivers a sigh of relief. This broom-like accessory will help you clean surfaces without you having to spend a muscle for rigorous scrubbing. It is suitable for staircases as it can clean the top surface, as well as the edges.

  • Karcher Surface Cleaner Attachment

Surface cleaners from Karcher usually have an 11 to 12-inch wide cleaning area. Using these wide surface cleaners will help you wash large flat areas quickly. It is a good accessory for cleaning driveways and patios with flat surfaces.

  • Vario Spray Nozzle

The Vario spray nozzle can be turned on with the following settings: 0-, 15-, 25-, and 40-degree spray. That corresponds to a blasting spray or a delicate one for your windows.

FAQ Karcher Pressure Washer Troubleshooting

  • Why Is My Karcher Power Washer Pulsating?

A pulsating washer may mean that the nozzle tips caught some dirt, which is causing enough obstruction. Use a nozzle cleaner to wash away that accumulated dirt on the tip.

  • Why Is My Karcher Power Washer Leaking?

This is a common problem, especially in the hose connection area. Leaks around this area may be caused by a reversed installation. For some models, the silver side threads to the machine, and the black knobby side takes the garden hose.

  • Best Detergent For Karcher Power Washer?

The best detergents that go with your Karcher Pressure Washer are those developed by Karcher themselves. That will ensure its compatibility with its cleaning capacity. Karcher offers biodegradable multi-purpose detergents. However, there are also solutions that are specific to some surfaces such as cars or other smooth surfaces.

  • Where To Buy Karcher Power Washer?

You can buy Karcher Pressure Washer at Amazon or eBay or visit the Karcher website to locate an authorized Karcher pressure washer dealers and service center near you.

  • How Much Are Karcher Power Washers?

Electric Karcher pressure washers cost within the range of 120 to 330 USD. Karcher gas pressure washers tend to cost higher. The price range is from approximately 200 to 350 USD.
