Features

All-in-one cleaning

The FC 4-4 removes dry and wet dirt in a single step. The integrated coarse dirt pick-up technology saves up to 50 % time by eliminating pre-vacuuming. Thanks to the hair filter, hair is also easily collected, even right up to the edges.

20 % cleaner than a mop

With the two-tank system, clean water is continuously fed from the fresh water tank onto the rollers, while dirty water is collected separately. No bucket carrying, no manual wringing, no scrubbing – for hygienic and convenient results.

Two cleaning modes

Choose between two modes depending on the floor type and level of dirt. Roller speed and water volume can be adjusted. Suitable for all hard floors such as parquet, laminate, stone, tiles, PVC or vinyl. With low residual moisture, floors are walkable again after about 2 minutes.

4 V Kärcher Battery Power

The durable lithium-ion exchangeable batteries offer maximum flexibility and are compatible with all 4 V Kärcher Battery Power devices. With the Duo fast charger, two batteries can be fully charged in parallel in just 70 minutes.

Smart tank level monitoring

An optical signal shows when fresh water needs to be refilled or dirty water emptied. The balanced ratio ensures that the dirty water tank is full when the fresh water tank is empty.

Practical & comfortable

The FC 4-4 is self-standing, easy to manoeuvre and reaches under furniture and along edges effortlessly. With a removable handle and parking station with roller storage, the device can be stored compactly.

Easy cleaning

The hygienic dirty water tank can be emptied without contact with dirt and is even dishwasher-safe. Rollers can be washed in the washing machine at 60 °C. A cleaning function for the device and rollers plus a supplied brush make maintenance even easier.
