Product details
With the FC 4-4 hard floor cleaner, you can skip vacuuming before mopping and remove both dry and wet everyday dirt in one step. With a long battery life of up to 30 minutes, it can effortlessly clean areas of up to 90 square meters. The included Duo fast charger allows for charging in just 70 minutes. A visual signal indicates when the fresh water tank needs to be refilled and when the dirty water tank needs to be emptied. Upon activation, the two rollers are automatically moistened with water from the fresh water tank. The amount of water can be adjusted to the type of flooring using the two cleaning modes. The FC 4-4 also cleans hard-to-reach areas and easily picks up hair. Direct contact with dirt is avoided thanks to the integrated and hygienic dirty water tank, which can be removed and cleaned after using the device. The FC 4-4 stands on its own and can be stored space-savingly thanks to its detachable handle. The device is suitable for all hard floors. The 4 V Kärcher Battery Power interchangeable batteries are compatible with all 4 V Kärcher Battery Power devices.

The Kärcher vacuum wiper is pleasantly compact and easy to hold. The two wiping rollers run in opposite directions, which should improve the cleaning effect. In the end, however, the result is not quite as convincing. We also find recharging the batteries cumbersome.

- For the most part "very good" cleaning performance, depending on the respective stains: smooth operation of the model
