Design and Cost

In terms of design, it is quite simplistic and what you would expect from a pressure washer. It comes in yellow and black.

While these colors may not necessarily be to everyone’s tastes, you cannot deny the quality of this pressure washer.

Its weight is 34 pounds and it is a compact pressure washer. This means it can be easily stored when not in use. Its dimensions are 34.33 x 13.07 x 16.77 inches. It has a water flow rate of 1.4 GBM.

The K5 comes with a useful handle to move the washer with ease and wheels so you can pull it instead of carrying it. Some users have had issues with their K5 toppling over and being unsteady when in use.

Others have noted some issues with the wheels being faulty, this is worth taking into consideration.

This pressure washer is an investment and is one of the more expensive models on the market. It is a high-quality product compared to many of its competitors, and as the brand, Karcher states, “it is built to last”. Although it is a high-end product, the quality is reflected in the price.

The Karcher pressure washer comes with a two-year warranty.


This pressure washer is powerful and particularly durable. It is made to be used time after time without damaging and it is a product that you can rely upon to last.

It comes with a patented water-cooled induction motor. This motor will help to prolong the lifespan of the motor overall, allowing the washer to last longer. This cooler will also help to minimize the noise the washer creates.

In addition to this, it helps to conserve energy, helping your energy consumption.

The Karcher K5 has an N-Cor pump. This pump is easy to maintain, is made out of durable materials, and will not corrode over time. This is important for a product that uses water at high pressures.


In terms of the pressure this washer creates, it is around 145 bars. It is a strong and powerful device so caution will need to be used when you are using it to prevent any injuries.

The Karcher is great at cleaning dirt from surfaces such as walls and patios. The pressure hose can reach heights of up to twenty-five feet. This is great if you need to clean tall walls. 

Types Of Wand

There are two types of wand attachments that come with the Karcher. The Vario Power spray wand and the Dirtblaster spray wand. 

The Vario Power spray wand - This attachment is great for your standard and everyday cleaning. It can be easily adjusted for either a lower or higher pressure and is powerful. This wand can be used to cleans floors and walls with the higher pressure setting.

If you want to clean objects such as your car, you can choose the lower pressure for a finer spray.

The Dirtblaster spray wand - This wand is perfect for particularly difficult to remove stains. It is more powerful than the Vario wand and is great for concrete and floors. The Dirtblaster takes half the time of your standard pressure washer to clean surfaces.

These wands are up to 50% quicker than their competitors. In terms of pressure, they provide 40% more pressure compared to other pressure washers. This means you will save time and your cleaning will be more efficient.

Detergent Tank

The blaster comes with an inbuilt detergent tank that will hold your cleaning solution. The tank can be removed from the washer to allow you to fill it with ease.

You can also change the flow of the detergent and how much is used. This is great if you are cleaning multiple things as it allows for less wastage.

Energy Consumption

The Karcher K5’s energy consumption is particularly good. The water-cooled induction motor cools down the machine and stops any excess energy consumption. 

As the water pressure and detergent can be adjusted you are not wasting unnecessary water or detergent.
