Product overview

✔ Now with a 7 Year Karcher Warranty*

This K4 Full Control water blaster with hose reel is ideal for occasional cleaning on moderate levels of dirt.

With the Full Control waster blaster, you will find the right pressure for any surface. The pressure setting is adjusted on the spray lance and can be viewed on the LED display on the trigger gun – for maximum control. You can switch from high pressure to detergent mode without changing the spray lance. The trigger gun is within easy reach and can be parked, together with the spray lance, during brief interruptions in cleaning.

Thanks to the height-adjustable telescopic handle, you can move the device around at a comfortable pulling height and store it compactly. And with the easy-to-use Plug 'n' Clean system, you can change detergents in one easy motion and check the filling level at a glance. The K4 also offers a lower centre of gravity for greater stability, a practical hose guide and a sturdy base.

The base can also be used as a second carrying handle, making it easy to lift the device onto a shelf or into the boot of a car. Order yours today.

What are the main benefits of the K4 over the K3. From what I can see it is the additional hose length and the water cooled motor. Anything else? & is the purpose of the water cooled motor to enable longer life & perhaps longer use per session? thanks
The biggest benefit with regards to a water-cooled motor as opposed to an air cooled motor is that you can use the water-cooled water blaster a lot longer without overheating the unit. This is beneficial when doing big jobs around the house where you need more power for longer periods of time. The K4 has a higher powered motor, larger cleaning area and a higher maximum pressure.

What does the "area performance" specification mean?
This is to help you size the water blaster to the job you wish to do - so cleaning 30m2 per hour is about limit in terms of keeping the motor in safe operating temps, avoiding activating the thermal cut out etc.

Would this be suitable for cleaning black mould off my drive and also for fences?
Yes this will do the trick.
