Please note that depending on stock levels we may special order in this unit for your order. Expect there to be a 1-2 day delay to fulfil this order from our standard freight guidelines.

This K4 Full Control water blaster with hose reel is ideal for occasional cleaning on moderate levels of dirt, with an area performance of 30 m²/h. 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.

Powerful and easy to use

I like how it has a built in hose reel and places to store all the attachments. Works well with PA Italy foamers making wearing your car a breeze.
