Karcher K2 Home Pressure Washer Review

The K2 Home is a small, lightweight and portable machine, used for cleaning exterior items including patios and decking, cars, bicycles and garden furniture. An upright design, wheels and a long handle makes this machine easy to use and to maneuver and the on-board storage solution means the trigger gun and accessories are stored neat and safely with the machine.

What We Say

What is it:

The K2 is Karcher's entry level pressure washer range with the "Home" being a general use practical solution to multiple cleaning tasks around the home. In a small neat package, the K2 comes complete with various lances and a patio cleaner attachment.

How we Tested it:

We actually happened to own the K2 as our previous pressure washer to the Kranzle we are now using and have used the machine for a variety of uses. We have observed its overall performance at such tasks as well as ease of use, value for money and range of uses.

We Liked:

  • Lightweight and compact making it easy to manoeuvre.
  • Good value for money. Can regularly be picked up in offers for less than £60.
  • Generous accessories for the price included, the patio cleaner is very useful and very effective at its task.

We Didn't Like:

  • We found that the handle often become detached whilst using it. We're not sure if this was a manufacturing fault or a design fault.
  • The hose feels a little short. Its 4 metres long but doesn't feel enough for many tasks and quite often end up pulling the machine over.


As an entry level pressure washer for use at home in patio cleaning and light cleaning tasks, the K2 is a competent performer. The included patio attachment makes short work of large patio areas quickly and effectively. We do wish the cable was longer and a rethink is certainly needed on the handle design as it needs to either be more secure or fold down rather than being a detachable handle. A few tweaks and more clarity on the K2's target market are needed for the K2 to fulfil its place in the market effectively.
