The most important facts in brief

The KHB 6 itself is offered without a battery as standard. The reason for this is simple: If you already have a Kärcher product, you can most likely use its battery and save money. However, the pressure washer is also available as a starter set with battery and charging cradle. The basic device comes with a lance and two different nozzles to attach. It is not explicitly designed for cleaning bicycles, but is recommended for this purpose according to the manufacturer. A wide range of optional accessories is available. Everything that is beneficial for bike cleaning was provided for the test.

An external water source is required for operation. Thanks to a commercially available quick-release connector, almost any garden hose can be connected. If there is no tap nearby, the optionally available suction hose can be used to draw water from a river, lake or container.

First impression

The cleaner is made of robust plastic and the supplied parts, such as the lance and nozzles, are easy to attach. An LED display on the battery indicates how much remaining runtime and power capacity is available. The KHB 6 sits comfortably in the hand thanks to the optimum weight distribution. The plug connections work well and the device is easy to use. Unfortunately, it cannot be stood upright with the lance fitted, as it tips forwards. This is poorly designed and impractical.

In use

Of the nozzles supplied, the one with the flat jet is ideal, you don't need the adjustable rotor nozzle. The water pressure is moderate and therefore perfect for bike cleaning as it prevents water from entering the bearings. If the "simple" flat jet is not enough, you can use the 5-in-1 multi-jet nozzle. As the name suggests, this offers five different nozzles in one. A very useful accessory for more targeted cleaning. Kärcher also offers a foam nozzle with a 3 dl container for cleaning agent. The supply of detergent can be dosed using the rotary wheel and the appliance produces a light to very compact foam.

Conclusion

Kärcher describes the device as a medium-pressure cleaner, which sounds strange at first, but it's exactly right. A device that produces a medium water pressure and is therefore ideal for gentle bike cleaning. In addition to its good cleaning properties, the Kärcher KHB 6 scores points with its compact size for transportation. The only drawback is that it is not free-standing when the lance is mounted, so you always have to lay it down. On the other hand, it is multifunctional and can be used for cleaning all types of objects and floors.

Recommendation

The foam nozzle and the 5-in-1 nozzle are useful accessories that you don't want to do without. The same goes for the suction hose, which makes you independent of a water connection. If you combine this with a 10-liter water tank from the DIY store, you can easily and conveniently hose down your bike anywhere.
