Product information

Pros and cons

According to our high-pressure cleaner expert

  • With an operating pressure of 130 bar, you can perform medium-sized jobs, such as cleaning your car and garden furniture.
  • You can adjust the water pressure to your job, so you always use the right power.
  • You can mix exactly enough cleaner with the detergent feed, so you can wash thoroughly and quickly.
  • Without included accessories, you can do fewer cleaning jobs and you damage delicate surfaces more easily.
  • You can't quickly store the cable without kinks,without a reel.

Description

The Kärcher K4 Power Control is the successor to the Kärcher K4 Full Control. This model has been upgraded on the inside and the outside. The high-pressure hose is now flexible and 8m long, so you can easily reach every corner. The accompanying app helps you make the most of your tool via useful tips and helps with selecting the right pressure. With this 130-bar high-pressure cleaner, you can determine the power of the water jet yourself. That means you're always in complete control of your cleaning job. The induction motor is water-cooled, so it does its job relatively silently. Whether you want to use it on your car, patio, or garden furniture, you won't be annoyed by its hum any time soon.

Good value for money, powerful and quick to clean.

  • easy to assemble with manual (even easier via manual in the app, but I only found out after putting it together with the paper manual).
  • powerful enough to clean my terrace
  • thanks to the T5, almost no more splashing water/dirt cleaning on the patio (instead of spray lance/dirt blaster)
  • Either the dirt blaster or the spray lance fits in the storage compartment, so one of them does not fit.

Our old Kärcher had unfortunately broken down and had to be replaced. After much deliberation (K4 or K5 or K7 or.... too much choice ;-)) opted for the K4 Power Control Home (premium) (without the car extras because you are officially no longer allowed to clean your car in front of your home) . The Premium models have space at the back to roll up the hose, so that's why we chose this one and that is very nice when storing. In addition, this newer model is much more powerful and quieter than our old "critter". The hose and cord are reasonably long (8+5 meters, so a total of 13 meters) so that you can clean a large area without an extension cord. Because this Kärcher is stronger than our old ones, cleaning is done much faster. By the way, we cleaned our terrace without the cleaning agent and that went well. And the spray cutter from our previous Kärcher damaged our terrace tiles and while using the T5 Terrace Cleaner we had no (new) damage. In short, very happy with it, hopefully this pressure washer will last for years to come.

Recommended

  • nice design
  • relatively quiet
  • Power adjustable
  • a lot of plastic

A switch from a supermarket pressure washer to a Kärcher is always welcome. It is simply a top product from a top brand. Quiet, economical and most important of all: it cleans extremely well. It's just a shame that it contains so much plastic, which makes it feel very cheap.

Short term: good buy. Long term: a waste of money

  • Lifespan

Have now bought a Kärcher 2 times and I will not do that again. After the warranty period of 2 years, the device starts to leak from the inside and you can take it to the landfill (where there are a whole pile of those yellow devices).
