Hard floor cleaner FC 4-4 Battery Set

Precise cleaning: The FC 4-4 removes dry and wet daily dirt precisely and quickly with its two cleaning modes. Includes exchangeable batteries and Duo fast charger.

An indicator lets you know when the fresh water tank needs to be refilled and the dirty water tank emptied. After activating the device, the two rollers are automatically moistened with the water from the fresh water tank. The water volume can be adjusted to the floor covering using the two cleaning modes. The FC 4-4 cleans even hard-to-reach places and the hair filter means the machine can easily pick up hair. The integrated hygienic dirty water tank can be easily removed and cleaned after use and because of the 2 tank system you are only ever cleaning your floors with clean water.
