Kärcher is expanding its range with a new mobile low-pressure cleaner. The OC 4 is a compact cleaning device that has been specially designed for flexible use on the move. With a working pressure of 7 bar and an integrated 8-litre water tank, the device is particularly suitable for cleaning dirty bicycles, outdoor equipment or animal paws. Kärcher states that around 3 to 4 bikes can be cleaned with one battery charge.
At the heart of the cleaner is a 10.8-volt lithium-ion battery, which is said to provide a runtime of 22 minutes. Charging takes place via a USB-C connection and takes around 3.5 hours, according to the manufacturer. For additional flexibility, the battery can also be charged in the car or with a power bank. An LED display informs the user about the remaining battery capacity.
When developing the OC 4, Kärcher placed particular emphasis on a space-saving design. When folded, the appliance measures just 17.2 x 29.0 x 29.8 centimetres. This is made possible by a well thought-out design in which the base, nozzle and hose can be stored in the 8-litre water tank. This reduces the height of the cleaner from 24.5 centimetres to 17.2 centimetres, allowing compact storage in tight spaces or small car boots.
The water tank of the OC 4 can be easily filled under a tap or from alternative water sources. A tight sealing cap is also designed to enable problem-free transport in the vehicle. With a weight of 3.02 kilograms, the cleaner is also easy to handle.
The Kärcher OC 4 works with a water flow rate of 2 litres per minute. A 2.8 metre long spiral hose is designed to ensure a generous cleaning radius. For particularly practical work, the trigger button can be clicked into place, allowing continuous spraying without the need to constantly press it.
Despite its performance, the new OC 4 is said to be pleasantly quiet in operation. This could be a particular advantage when used on campsites or in residential areas.
The OC 4 from Kärcher is supplied with a charger and a USB-C charging cable as standard. The manufacturer also offers the cleaner in three different set variants, each of which includes a transport bag and special accessories for bicycles, camping or pets.
The multi-jet nozzle is a new development in the range of accessories. This combines four different jet types that can be adjusted depending on the cleaning task. Kärcher states that existing accessories for the company's low-pressure cleaners are compatible with the OC 4, which opens up additional application possibilities.
