Shopping Guide: Everything You Should Know About Karcher Pressure Washers
The power and efficiency offered by Karcher pressure washers is on a whole other level, compared to using a simple garden hose. These devices are smaller versions of the industrial pressure washers invented by Alfred Karcher, and are the perfect tool for working around the home. To help you find the model that is best for you, in this section we answer the most frequently asked questions about Karcher pressure cleaners.
What is a Karcher pressure washer exactly?
The German inventor Alfred Karcher created the first industrial cleaning machines that used pressurized water towards the end of the 1940s. However, it was not until 1984 when the company designed and released Karcher models of pressure washers, similar to those available today, which were intended for domestic or semi-professional use.
They have since evolved into the most popular outdoor cleaning tool (perhaps along with the leaf blower), to the point where these days saying “Karcher” is the same thing as saying “pressure washer”. They are the most popular type of appliances for cleaning outdoors. Especially if you have a house with a large yard, or any outdoor area that requires a little maintenance.
How do Karcher pressure washers work?
In order to be operated, a Karcher pressure washer must be connected to a water outlet and an electrical outlet. They are very simple to use. You just need to choose the most appropriate level of pressure, depending on the type of cleaning you want to do. Every Karcher pressure washer has a slightly different variation in power capacity and the accessories it uses.
The water first passes through a pump that generates pressure of between 110-180 bar. All models of Karcher pressure washers on this list, except for the K2 Basic, are capable of using added detergent, which improves their cleaning performance. There are different types of guns and nozzles to control and direct the propelled water.
What are Karcher pressure washers used for?

What are some good tips for using a Karcher pressure washer?
Although these tools are extremely simple and intuitive to operate, here are some useful recommendations that will help you get the best performance out of your device. These important tips should be taken into account from the moment you plug in your Karcher pressure washer, until your store it away again.
- The water and power outlets must be close enough to the area you will be cleaning.
- In the event that you need an additional extension cable or more hose sections, they must meet minimum safety standards.
- Select the correct level of pressure, suitable for the type of cleaning you wish to perform. Too much pressure can potentially cause unwanted damage to less durable surfaces.
- Security: Remember that electricity and water are a dangerous combination. Ensure that all plugs and extensions remain well insulated.
- Use the correct type of detergent for the type of cleaning you want to do. For example, there are products available that are specifically designed for washing a car.
What accessories and components are available for Karcher pressure washers?
High pressure washers consist of a water intake, pump, detergent container, hose with a head that offers different levels of control. All the models on our list of Karcher pressure washers are shipped with a varying range of basic accessories. There are also extra accessories that can be purchased separately.
Karcher pressure washers include standard accessories – such as the single spray head, a turbo nozzle, a gun with a high-pressure hose, and a water filter. The filter is important to make sure the device functions properly, and will prevent it from breaking down by keeping dirt particles out.
In addition to the basic accessories, when you buy a Karcher pressure washer you can also purchase a car kit or a home kit. The car kit includes a pair of washing brushes – one of which is made to be used with a type of foam detergent specifically designed for cleaning your car.
The home kit includes a surface cleaner, as well as detergent. The surface cleaner is designed to avoid spills and minimize any splashes, and it can be used horizontally or vertically.
There is a Karcher pressure washer suitable for just about any type of job you can think of. There is a special kit for cleaning bicycles and another designed for cleaning wood. Karcher also has a wide range of additional accessories and products out on the market.
Now you know that there are many different models of Karcher pressure washers, with different power capacities that consume different amounts of water and electricity. When choosing the model that best suits your needs, it’s important to keep the following factors in mind:
- Intended Use
- Frequency of Use
- Size of the Surface to be Cleaned
- Type of Cleaning
There are so many different ways to use a Karcher pressure washer, maybe some that you haven’t even considered. It’s a good idea to buy the model with the most features, while still remaining within your budget range, so that it will be suitable for as many different applications as possible.
For example, if you buy a basic model just to wash your car, it is highly likely that after it arrives you will decide that you want to use it for other tasks, such as cleaning the facade of your house. Having a more advanced and more powerful unit, will allow you to use it in ways you never even thought of.
Frequency of Use
If you are someone who will make up any excuse to put off cleaning up around the house, it is likely that your Karcher pressure washer will spend most of its life forgotten, packed away in a corner somewhere. However, if you are one of those people who takes pride in presenting their home all neat and tidy to their neighbors, you will more than likely use it much more frequently. The more often you plan to use your new Karcher pressure washer, the more money you can justify spending on it.
The frequency of use will also depend on your lifestyle. You won’t be washing your car very often if you only drive a short distance to work on weekdays, compared to an SUV that you drive off-road every weekend. If you have a medium-sized house with a large yard, and a garage with five bikes and three cars, the frequency of use is going to be “high”.
The most powerful Karcher pressure washer we reviewed in this article is the K5 Full Control Home. This version is the most suitable for frequent use over large areas, and for cleaning away the most persistent dirt and grime.
In the following table we compare the power ratings of the most popular models of Karcher pressure washers:
|K5 Full Control Home||145 bar||2100 W|
|K3 Full Control||120 bar||1600 W|
|K2 Full Control||110 bar||1400 W|
|K2 Basic||110 bar||1400 W|
Size of the Surface to be Cleaned
It seems obvious, but it is worth remembering that cleaning your front porch is not the same as a cleaning a parking lot. Performance needs grow proportionally to the size of the surface to be cleaned. Let us now review the performance of each Karcher pressure washer by measuring the square feet that it can clean per hour:
|K5 Full Control Home||430 ft²/h|
|K3 Full Control||375 ft²/h|
|K2 Full Control||215 ft²/h|
|K2 Basic||215 ft²/h|
Type of Cleaning
Difficult dirt and grime need greater jet power. The K5 and K7 are the best models for dealing with embedded dirt and surfaces that are hard to get clean. They are suitable for dealing with grease and heavy-duty tasks. However, if you only need a pressure cleaner for simple tasks, like cleaning your bike, a basic model will be enough for your needs.
Karcher pressure washers are based on the design of the industrial cleaning machinery that was originally created by the founder of the brand back in the 1940s. In the 1980s the first domestic models were released and Karcher has been the industry leader ever since.
To find the Karcher pressure washer that best suits your needs, you just need to consider the factors we outlined in this shopping guide. Karcher have a wide range of products available on the market, so there is definitely something for everyone.
