Karcher K5 Review: Premium Full Control Pressure Washer

Karcher K5 Review: Premium Full Control Pressure Washer

The Karcher K5 Premium Full Control is a powerful pressure washer and patio cleaner that features a number of improvements over earlier versions of the product. It is capable of handling almost any outdoor cleaning task with ease, and it is actually enjoyable to use.

In this Karcher K5 review, I will go over the features that make this pressure washer stand out from its competitors.

The ability to control the pressure at the touch of a button, the convenience of the 3-in-1 multi jet lance, and the included T350 patio cleaner are just a few of the features that make this a powerful and efficient pressure washer.

The on-board storage and wind-up hose add to the convenience, and the 8-metre hose is longer than most of the similar machines on the market. Karcher has produced a number of models of pressure washers, but not many can match the K5 when it comes to raw power and convenience.


  • Powerful 2100W motor
  • Control the pressure at the touch of a button
  • 3-in-1 lance makes it easy to switch between cleaning jobs
  • Handle and large wheels make it easy to move around


  • Slightly on the heavy side
  • One of the more expensive models

Karcher K5 Review: Design and Appearance

Just like the earlier versions, this Karcher K5 Premium Full Control Pressure Washer still maintains the yellow colour scheme. The body has, however, been improved and made more suitable for outdoor cleaning chores.

It is a small and compact machine and although it is quite heavy, the large wheels and pulling handle make it easy to move around when cleaning your car, patio, and other concrete surfaces.

It comes with an 8m hose that is long enough for most cleaning tasks and the LED display on the power gun makes for a very sleek and contemporary design.

Furthermore, it comes with a 2100W motor that features a unique cooling system designed to increase the lifespan of the motor. The on-board storage space is generous enough to house the additional accessories that come with the machine.

Specification and Performance

Karcher K5 Cleaning

It is safe to say that one of the most impressive things about this pressure washer is the raw power; it is a very powerful machine when compared to similar models from other manufacturers. The 500 litres per hour flow ensures that you clean adequately with little or no wastage.

Most pressure washers in this size range come with 5m hoses, however, the Karcher K5 Full Control comes with an 8m hose that enables the user to move around without having to drag the machine along at every point.

All these features make the machine suitable for removing deep-seated dirt and grime from different surfaces.

Full Control Spray Gun

Karcher K5 Review Premium Full Control Pressure Washer

The Full Control spray gun is one of the things included in this new K5 version. An LED display is fitted on the spray gun to show the level of the power setting; with this, you can always check for the right setting before you start cleaning.

On the trigger gun, you can also adjust the power setting depending on the type of cleaning and the surface you want to clean; the power with which you clean your patio is not the same as you clean your car with if you don’t want to damage your car’s body.

The trigger gun is powered by two aaa batteries which are included in the package.

On-board Storage

It is not enough that this Karcher K5 pressure washer comes with various additional accessories, there should be storage space for these accessories so that they can be easily accessed when they are needed. The on-board storage space houses the 8m hose, the trigger gun, and the connected lance.

All you have to do is to reach for any of these accessories when you need them and put them back in place when you are done with them; you don’t have to dedicate a space for these items as you can easily store them on-board.

Karcher K5: Additional Accessories

Karcher K5 Accessories Review

The K5 Full Control Pressure Washer Comes with a number of accessories, more than these, the machine is compatible with other Karcher pressure washer accessories. Some of the accessories that come with the machine are:

8m high-pressure hose

The machine is powerful and it requires a hose that can handle its power. The 8m hose included in the package is a high-pressure hose with sufficient length to enable the user to move around without always having to move the machine with you.

Vario Lance

This enables you to easily regulate the water spray when cleaning different surfaces. All you need to do is twist the Vario Lance to adjust between a fine spray and a heavy jet stream, depending on the surface you want to clean.

Dirt blaster

This accessory produces a very powerful rotating jet that works efficiently on stubborn dirt.

Stone detergent

Karcher K5 Review: Final Thoughts

The Karcher K5 pressure washer is a very powerful pressure washer that is suitable for most outdoor cleaning tasks. The Full Control spray gun is a very interesting feature and it gives you more control during your cleaning activities. It outranks similar pressure washers in power output, flow rate and even bar pressure.

It is a little expensive when compared to similar models and it is quite heavy for a small machine, however, these are not so surprising when you consider the specifications and the performance of the machine.

Judging by the quality and performance of the Karcher K5, it is one of the pressure washers you should consider whenever you think of buying one for your outdoor cleaning.
