Product news: The Kärcher OC 4 cordless pressure washer is designed for anyone who needs a cleaning solution on the go. Thanks to the integrated lithium-ion battery and large 8-liter water tank, cleaning is possible without the need for a power or water connection. Kärcher nozzle technology enables gentle yet effective cleaning. With the optional Bike Kit, you're perfectly equipped for cleaning all types of bicycles.
Not everyone has access to a water connection or wants to load the dirt from their last trail ride into their car. This is where Kärcher comes in with the new OC 4 cordless pressure washer: a powerful, mobile low-pressure washer specifically tailored to the needs of cyclists and outdoor enthusiasts. With a larger tank capacity, modern battery technology, and clever accessories, the OC 4 is the logical evolution of its popular predecessor, the OC 3 – and a true all-in-one solution for on the go.
Technical overview: Compact, wireless, powerful
The Kärcher OC 4 cordless pressure washer operates at a constant low pressure that protects sensitive bicycle components such as bearings, seals, and brakes – yet still has enough power to reliably remove mud and dust. The device draws water from a removable 8-liter tank, which is twice the capacity of the 4-liter tank of the OC 3. This allows one to thoroughly clean one or two bicycles.
The integrated Li-ion battery provides up to 22 minutes of runtime—more than enough for multiple cleaning sessions. A particularly practical feature: Charging is now via USB-C, making mobile use much easier. A full charge takes approximately 3,5 hours.

The scope of delivery included in the Bike Kit makes the system particularly attractive for cyclists. Included are:
- Multi-Jet 4-in-1 nozzle: for targeted blasting, wide fanning, gentle rinsing and spray mist – depending on the degree of soiling.
- foam nozzle: creates powerful cleaning foam – perfect in combination with the included Natural Bike Cleaner.

Whether off-road, at the campsite, or in a van – the OC 4 demonstrates its strengths wherever there's no water connection. This portable cleaner is especially valuable for mountain biking after wet rides. Thanks to the 4-in-1 nozzle, coarse dirt can be removed specifically, while delicate areas can be gently rinsed.
A full tank is sufficient for thoroughly cleaning one heavily soiled bike or two lightly soiled bikes. The amount of water is easy to control – with a little practice, you can establish very efficient cleaning routines. If you need more water, you can optionally connect a suction hose – perhaps from a canister or stream. Ideal for extended van life.
The Kärcher OC 4 cordless pressure washer has been redesigned not only technically but also visually. The device also bears Kärcher's new Eco-Design seal, thanks to its particularly resource-efficient operation. This means no energy waste, low water consumption, and sustainable packaging.
A clever addition is the new USB-C port for charging – it allows you to use power banks, car adapters, or solar panels for power supply. Ideal for longer trips or camping.
The Kärcher OC 4 with Bike Kit is more than just a portable water sprayer – it's a sophisticated cleaning system for anyone who wants mobile, flexible, and thorough cleaning. Combined with the appropriate accessories, the Bike Kit becomes a true care center for any bike that's regularly used outdoors. The RRP is €199,99.
