 About The K4 Pressure Washer

The K4 has a trigger gun that allows you to fully control the pressure, this makes cleaning various surfaces very easy as you control how much pressure you need for the task in hand. On the trigger its easy to switch to the detergent mode when needed and it features and LED display, this allows you to see what what the pressure is set to. The LED display is powered by 2 AAA batteries.

Its upright design makes it very stable when its in use and with less chance of it tipping over, it also has some storage space for the lance to fit into. One of the best bits is the Plug and Clean system as all you need to do is plug in the cleaning liquid of you choice. Over the years Karcher have done many improvements to their high pressure washers and one of them is making the on and off switch higher up on the machines to make it easier to use with less bending down to turn them on or off.

Have you got a pressure washer? If your answer is no why not pick the K4 for all your outdoor cleaning needs, have a look at your patio and driveway, can you see how dirty it is? One quick blast with this washer will show you how dirty you patio or driveway really is. It might look half clean to you but until you try a pressure washer you will not be disappointed. Maybe you have a car or a van that you always take to a car wash or even wash by hand, think of the money you would save and not forgetting the time you would save as well. Hope you have enjoyed reading the karcher k4 review and hope this has helped make the right choice.
